How do I enable USB tethering without turning off the WiFi?
I want to tether my phone's WiFi connection to my computer via USB.
There's a setting for USB tethering, but when I enable it there is a message

Wi-Fi is turned off when USB tethering or Mobile HotSpot is active. To turn on Wi-Fi, please turn off USB tethering or Mobile HotSpot.

But what's the point of tethering if the Wi-Fi is turned off? I have no connection to share with the computer if the Wi-Fi is not on.
If I turn off the Wi-Fi before I try to enable USB tethering, it shows the message

Unable to connect
You need a network connection to use this application. Please turn on mobile network or Wi-Fi is Settings.

So...it needs Wi-Fi to tether, but when I turn on the tether, it turns off Wi-Fi? I don't understand. How do I keep the connection from being turned off when I try to enable the USB tether?
I'm using an HTC One phone.

Looks like this was asked before and answered. http://android.stackexchange.com/questions/3134/can-i-use-my-android-device-as-wi-fi-adapter-for-my-pc-i-e-tethering-to-pc-thr
But if this doesn't help you. Let us know what device and version of android you are running and then we can dig around a little bit more.

Mine works even Wi-Fi is turned on. But when WiFi hotspot, it actually needs to turn off WiFi adapter because it will interfere with the WiFi network.

I resolved this. The solution seems a little bit hacky, but it worked.
I unplugged the USB cable, turned on the Wi-Fi, enabled the USB tether option, then plugged in the USB. When I plug it in, it shows the message

Wi-Fi is turned off when USB tethering or Mobile HotSpot is active. To turn on Wi-Fi, please turn off USB tethering or Mobile HotSpot.

and then after a few seconds

USB tethering is ON

If I turn on the Wi-Fi after the first message but before the second message, the Wi-Fi is not turned off automatically and my computer is able to successfully connect.

OP mentioned that they have an HTC One in the question

I know this is a little old now, and neither the question nor the answer was ever clarified, but I just encountered this issue and found a workaround I wanted to share.
I'm using Joshua Wise's HoRNDIS to tether my HTC 10 (Verizon, 'Android O' OTA update, unrooted, USB C) to my 2017 MacBook Pro (USB C/Thunderbolt). The tethering works fine, if only in a slightly undesired way: my phone demands that WiFi must be shut off in order to tether. I want my phone to bridge the WiFi to my MacBook (i.e. I've forgotten the WiFi password).
Furthermore, trying to turn the WiFi on through the system UI while tethered gives two options, either continue tethering or stop tethering and turn WiFi on.
My solution was to make a Tasker widget on my home screen with the action "Wifi Set On". This Tasker action turned the WiFi on, and my MacBook didn't lose internet access. I verified WiFi usage by turning mobile data off and browsing on my MacBook for a while. It's my suspicion that every UI option to turn the WiFi on is linked the dialog box to turn tethering off, but getting around the normal UI to change your WiFi settings may work (Tasker may not be required.)

Android exclude WiFis
In my area I have a lot of paid WiFi hotspots that are open and my android connects to them automatically.
Can I set that WiFi's only with certain keyword in their name(SSID) would not connect to?
EDIT:
Imagine there several hundred hotspots of open wi-fi hotspots on diferent networks configurations and so on. The only common denominator is that all of the have network name in ssid. Lets say 'crazy sheep'
On a flip side same area has hundreds of free open wi-fi hotspots again all in different networks and these have almost no common denominator.
In the past I have done some Android development. So I do not look for settings tutorial. If the function is in stock there is a little chance I will not know about it.
I am looking for
An app that adds an option to write a query (regex is fine) with SSID as a variable in it. That would omit matching networks from initiating connection but would not affect other networks

Tap on those wifi ssid names and and use forget network to remove phone from automatically connecting to the network

In addition to Rajat's answer ("Forget" each network), when you connect to a new network or re-connect to a network you're device has "forgotten", you have the choice to clear the "Connect Automatically..." checkbox. If you do that, when you choose that connection, it will ask for the SSID each time.

Connection Oriented Channel for L2CAP
Does Android support Connection oriented Channel for L2CAP in BLE?
What about in Android M ?
Thanks !

answer from Texas Instruments can be found here

neither of the major smart device OS's support L2CAP CO channels

meaning iOS and Android. posted Oct 7, 2015, after the launch of Marshmallow.

Looks like BlueZ has the support  -  in Bluez 5.x. I will update on this in sometime after checking more.

but BlueZ isn't used in Android...

Exactly, Agreed. But I was commenting to the above comment : "neither of the major smart device OS's support L2CAP CO channels".

Yes will be interesting to see how it develops for use on Ubuntu, raspian, etc

Cyanogenmod not saving video + root missing
After rooting and flashing my LG G3 D855 with Cyanogenmod 12.1 I was quite satisfied, however I noticed that when I shoot a video from the rear camera the video would not save. The capturing would proceed normally but when you click on stop recording and look for the video in the gallery, it wouldn't be there.
What do I do with this?

The problem was that the back video camera was set to record in 4K resolution.
The fix for the video camera issue is:

Go to the default camera app.
Swipe from the left to see the "Camera" "Video" Menu, on the bottom right corner the is a gear icon, press it to go to camera settings.
Go to resolution and quality and change the back camera video quality to 1080p instead of 4K.

For the root problem I found that you need to enable root once you have Cyanogenmod so you need to:

Activate Developer options (settings->about phone, tap 'Build number' multiple >times).
  In Developer options, tap 'Root access' and enable either "Apps" or "Apps and >ADB"

http://wiki.cyanogenmod.org/w/User:PsychoI3oy#Superuser_on_CyanogenMod_12.0

Please enlighten how changing the resolution from 4K to 1080p is related to video not getting saved?

I have got no idea to be exact, but it worked.

Samsung Galaxy S3 camera light keeps flashing
Ever since I updated the software on my Galaxy S3 the camera light flashes randomly all day, it also flashes when my alarm goes off.
I cannot find anywhere in my settings how to disable this annoying light. My flash notification is not checked off. Please help!

S3 users have reported similar issue while receiving calls and alarm going off at AndroidCentral forums here.
The solution posted there is to go to Settings > My Device > Accessibility > Hearing > Flash Notification
Un-check Flash Notification.
Even if the flash notification box is not checked, check it once and un-check it again. It should solve your problem.

Was annoying, but has stopped, by doing the following:
Go to: Settings > My Device > Accessibility> Hearing> Flash notification
Select flash, close out, return and deselect flash.
Working properly now!

This phenomenon could be due to some rogue app that is using the permissions of the camera to take pictures or activating flashlight without your intervention.
Check with some app like F-Secure App Permissions, applying the advanced filter CAMERA, FLASHLIGHT (applying OR operator as shown in the screenshots).
In the resulting list, look for any suspicious app (mainly a game or another app that should not be using those permissions) and uninstall it (you can uninstall apps directly from F-Secure App Permissions by long-tapping its name in the list and tapping Yes in the confirmation message).

I found it was a flashlight app I had downloaded. It had permissions to override various functions. After uninstalling the app, the flashing is gone!

Clear "Recent Labels" list in Gmail
It's bugged me for awhile that Gmail shows a "Recent Labels" list when viewing the labels.  Does anyone know how to clear this list or even remove it?
Gmail: 4.7.1
OS: Jelly Bean - 4.1.2

Although the Original Answer is already in place, let me just re-phrase it, which hopefully resemble Vanilla Android AOSP based phones.

Open "Settings" application
Choose "Apps" or "Applications" from the list of different Settings.
Locate "GMail" App in the List of Apps shown.
Select "Gmail" App and in this screen, there is "Clear Data" option available.  Tap the button Clear data. Confirm the operation and wait for Gmail Sync to complete.

This should clear the Recent labels.

Do the following:

Go to App info for Gmail: Open app drawer and drag up the Gmail icon to the option App Info.
Tap the button Clear data. Confirm the operation.
Wait for Gmail sync.

You'll be greeted again as if it was the first time you opened Gmail, but Recent labels list will be cleared.

Samsung Galaxy Ace 3 has USB OTG (On The Go)?
Samsung Galaxy Ace 3 supports USB OTG (On The Go)?
I've dedicated a long time to research, both in Google and on specialized sites (rich in Technical features), but I could not figure out if this device has this feature.
Here in Brazil this device is marketed as Galaxy S II Duos TV, much poorer in specific device technical features since it was only released for this local market. Therefore if I find out about the Galaxy Ace 3, brother machine, I think I find the answer.
Having to buy a device only know it's crazy, but I have real buying interest for being OTG valuable.

phoned to samsung hotline today, they said no.

"Your phone is too slow" Message that have been shown after every few minutes
An app has been shared from my friends phone. But when I try to open that app, I'm getting "Your phone is too slow" message. After uninstalled the app, I'm still facing the same problem.

Post a screenshot of the message, and mention the Android version and device name?

i am using lenovo A7000 mobile with android5.0

Honestly, android doesn't have any inbuilt way to give out warnings like that. It does have code to switch to alternate methods if the device's specs aren't enough, or it may hang/lag, but it never gives out any such message. So a high chance is that the message is a spam/advertisement. Can you post the screenshot of the message here? It would help knowing the possibilities (since android system toasts and messages look quite different than advertisements etc, mostly). Plus your phone is good enough, not that slow. So such possibilities are even high.

Try to stop an application that use so much memory in the background by doing :
1. Go to your phone Settings
2. Select "Apps"
3. Select the tab "Running"
4. Click on an app that you don't use it or have a high memory consumption
5. Click stop
Hope this works.
If this method doesn't work, you might need to factory reset your phone.
That's my suggestion

Are you sure it's a genuine message and not an Advertisement by a rogue app?

thats what i am not able to confirm

Is there an app called "Mobogenie" in your phone? You need to un-install it. It gives you some pop-up add such as what you having now.

GPS for WiFi only MiPad
I have a MiPad which works only with WiFi. How do I use it as a GPS device? Google map isn't able to access my location and my MiPad doesn't support tethering.

I found the solution on MIUI website here:
(Click image to enlarge)

Prerequisites:

Have a device that has GPS built-in and tethering/hotspot.  In my case, I'm using the Xiaomi Mi 3.
Download and install TetherGPS Lite on both the Xiaomi Mi 3 and Xiaomi Mi Pad.

How it works:

In the Xiaomi Mi Pad, enable Settings-Developer Options-Allow mock locations.

GPS location must be enabled on both devices.

On the Xiaomi Mi 3, enable Settings-Wireless & networks-Tethering & portable hotspot-Portable hotspot.

On the Xiaomi Mi Pad, enable Settings-WLAN and I connect to my Xiaomi Mi 3 hotspot.

Start TetherGPS on both devices.

On the Xiaomi Mi 3, click on Start Server.
On the Notifications bar, you will see the IP of the TetherGPS Server.  Note it down.

You will also see that your device will be searching for the location until it is found.
On your Xiaomi Mi Pad, click on Start Client.

Under the Notifications bar, if you find that TetherGPS Client is not working, go into the TetherGPS app.  Uncheck "Automatic Broadcast IP" and key in the IP you noted down earlier.  Click on "Stop Client" and on "Start Client" again.

If the setup is working, you will notice that both Notifications bar will show the connection time of TetherGPS.
Start your Google Maps or any other navigation apps and enjoy driving from point A to point B using your big 7.9" screen.

Why does my phone say I am roaming when connected to my "home" network?
I recently got a new phone, the Elephone P7000 and it runs stock android 5.0. Everything seems to work perfectly apart from the fact that most of the time the top status bar says I am roaming.
When I check which network I am connected to, it says I am connected to my actual provider network, so why does it say I'm roaming. The only partial fix to this issue is manually selecting the cellular network, and this only works for around 10 minutes with no roaming shown in the status bar, after that it switches (? – I don't know if it actually does since I still seem to be connected to the same network) by itself when I am not moving and I get the roaming indication again.
So far, this does not seem to affect my ability to make calls or receive messages, but I find the roaming indicator in the status bar to be very unsettling.
Edit to clarify:
On my network operator selection screen, I see the same operator name multiple times and only upon selecting one specific (the topmost) option I get no roaming indication.
Any help or clarification would be appreciated.

Let me guess, you're on EE? Or a network that uses EE for it's coverage? (like Virgin or Asda). These swap between the Orange and T-mobile masts depending on which has the strongest signal, and when that happens the phone thinks it's then "roaming".
When you see 2 versions of the same network operator, you'll often see different capitalisation, e.g. "virgin" and "Virgin". One of these is actually Orange and the other is T-Mobile.
It doesn't have any negative effects.

Internally, mobile networks identify themselves through a Mobile Country Code (MCC) and a Mobile Network Code (MNC). The MCC and MNC of "your" network are stored on your SIM, along with other data with which your phone identifies itself to the carrier.
Each cell tower transmits a cell ID, which also contains the MCC and MNC. When you are connected to a mast whose MCC/MNC pair differs from that on your SIM, the phone assumes you are roaming on a different network. This is usually the case when you are traveling abroad, but there is also "national roaming" (the MCC is the same but MNCs differ).
However, some carriers have multiple MNCs within the same country. US carriers have a handful of MNCs. In Europe this is less common, but occasionally mergers between carriers have resulted in multiple MNCs being assigned to the same carrier.
Edit: I recently saw a portion of the Android source code which has lists of which networks are not considered “roaming” for a SIM issued by a particular carrier. Thus, if you are running a recent version of Android and you’re on a network which uses multiple MCC/MNC pairs, Android will not show the roaming icon. However, this will only work if your phone runs a version of Android which already “knows” about these MCC/MNC pairs being part of the same network. If it doesn’t, Android will mistakenly report your status as roaming.

Android 4.4.2, Google Play Store error: No connection, but pages loads fine in browser
The Android version is 4.4.2. When I open Google Play Store, it says "Error, no connection"But when I open browser I can load pages like Google.com.
I tried clearing cache, logging with other Google account, but it isn't working.
Any ideas to resolve the issue?
EDIT: I downloaded Anututu and it says that there is root access..

I haven't opened Google Play on this phone before..It just shows that error message..Also youtube isn't blocked..

going through this answer might help you
http://android.stackexchange.com/questions/108967/cant-connect-to-google-play/116688#116688

It happened to me when I did factory reset, solved after upgrading the play store, go to the play store settings scroll down and click on version number it will update to the latest version of play store

I had this issue once too when flashing a custom ROM. Download an Play Store apk for Android 4.4.2 and install that.

Try going to Settings > Applications and finding Google Play Services. Clear the cache and force stop the app. If that doesn't work, try clearing data instead of cache and then force stopping it.

I can't clear the data, also I can't Force stop it, because I can't press the button..Clearing cache didn't help.. :\

Sounds strange: If you cannot clear its data, have you setup a Google account at all (and if so, when)? Is the "uninstall updates" button enabled (also check this for the Google Play Store app)? For how long are you using the device already?

Yes, I've logged in my google account. I tryed clearing the data from Google Play Store app, and force stopping it, but it didn't work..There is no button uninstall updates..The device is new, from 1 day.

Add obsolete phone to contact
I have old messages from contact sent using temporary phone number he had on vacation. I want those messages grouped under his name in conversations, so I added it as another number to contact details. Messages are now fine, but this "obsolete" number is now clutters phone list when I tap on contact and need to chose what number to dial.
Is there a way to add a number to contact, but make it not appear in list of numbers to call when you select contact?
As first answer mentions, I can set other phone as default, but this still leaves obsolete phone on contact summary page and you can still accidentally call it with mis-click. I'd really like it to only show on contact edit page and be uncallable or at least not without confirmation prompt.

What device? Many phones allow you to set a "default" number on a contact, that one is used by default. Try to edit your contact and see if you can set one as the default.

@acejavelin, I already have correct default number. This doesn't solves question "how to hide obsolete number" at all.

Then the answer is you can't... If you remove a number from a contact, the SMS messages associated with that phone number will no longer have a contact associated with them, thus will display as the number only as the contact.

You can select a number as "default" or "main" and then this number will be dialed when you call that person.
Usually it can be done by long tap on a number and then selecting "Set as default".

How to rotate emulator screen (not device orientation)?
Some apps run in landscape orientation, but sometimes allow you to see some picture in higher resolution by displaying it as portrait-oriented full screen image. Those are mostly games that allow you to tap character's portrait in profile to see it - Soccer Spirits, Chain Chronicle and and pretty much any other game that features character art as one of its draws.
IRL you supposed to turn your device to look at image, but how can I do that on Genymotion or any other emulator? It does have button to change device's orientation - i.e. internal state on what device thinks about it and will automatically turn screen accordingly, but it obviously doesn't help with apps that have fixed orientation.
Is there any way to just rotate emulator window?

Nox version 5.0.0.0 added this feature. Quote from changelog:

Added Rotate button to change Nox screen display from vertical to horizontal or back with just one click.

LG G Flex navigation buttons problem
A couple days ago I noticed a problem who is starting to frustrate me.
My LG G Flex (LG-D958) is having laggy navigation buttons.
If I open text messages, and my keyboard pops out to write, if I click "Home" button it wont react. It's the same with other two buttons "Back" and "Properties".
I tried to click it multiple times in a row, but nothing. But after i get out from the messages or any application where I need to use keyboard(viber,whatsapp), it's still almost the same. I also tried on the home screen clicking the home button for multiple times and it only reacts on only second-third click.
There are no dead pixels or any kid of problems on the display, the touch on any other part of the display is fine and works correctly.
Android version 4.4.2
Update 2#
I downloaded MultiTouch tester on Google Play, and by what I see the display is okay, but I cant test the navigation buttons...
Update 3
Okay, Ia managed to test the touch where the buttons are. I hid them and then started the application for multi-touch testing. And it seems that the touch doesn't react on a small part of the display where the nav. buttons are.Below is the picture of the phone. If i got more down the touch signs will disappear.

I am not sure if this can be a solution for you but it is worth a try right? Go to the "developer options" inside your settings app. If it is not listed there, go to "about the phone" and click 7 or more times on the entry "buildnumber". Now go back and head to the devoloper options. Under the subcategory "Input" there should be an option that touch gestures on the status and nav bar should be ignored by apps. Try disabling/enabling it and see if it makes a difference. I hope it does.

In input subcategory is only "Show touches" and "Show touch data" options

Google+ data connection issue on Samsung S4
I'm having a strange problem with my Samsung S4 using the stock, current firmware. The phone is new and straight out of the box. Updates have been allowed to proceed and now report current.
Google+ reports 'Data connection error'. This error should not be taken literally as there is very clearly a fast network connection available: on both 4G and wifi. Every other network accessing app, including other Google apps (including those using the Google user account) work fine.
I've cleared the app cache and data without effect. The issue existed prior to and after a Google+ app update.
Any suggestions?

Google+ comes bundled with the firmware installed on your S4. Just uninstall the latest update via Application Manager to take you back to the Google+ version that comes with the phone. If you still get the same error, log a bug report with Google and get them to fix their crappy product.

As I stated above, the issue exists both before and after the Google+ app update: perhaps I didn't make it clear enough that the initial version (prior to update) in the version locked in firmware. What is the point of emailing Google, I might as well shout at the wall.

Well, a friend of mine has Google+ v4.2.4 on his S4 international version and it seems to run fine before and after the update. What version do you have on your device?

It is unfortunate that this question stayed without reply. It seems I have the same issue but with my S3. The phone works perfect with all apps on Wifi and 3G/LTE. However, for the last 2-3 weeks, Google+ just stopped being able to update. I tried to clean data and cache without success, then I cleaned data and cache and uninstalled the app to go back to the firmware version of Google+, same issue. I then re-cleaned data and cache and re-updated to the latest version, Google+ is still not able to connect.

Sending linux commands over serial
I have a question about being able to send Linux commands over a serial connection to an Android device.
I have heard of putty and tried to use it, but i am ultimately lost with it. Like if I was in the Linux shell of the Android and could type, reboot and the device would reboot. The Android device has a virtual serial connection, and I have been able to connect to it using putty, but I don't know where to go after that. I know this is confusing and may be completely wrong, thank you for your time in advance.
I also have been able to connect to it with QPST, and see a 100mb drive come up with some files in it.

what do you want to do with linux commands?.You can check for devices in the i2c bus and you'll get to see the debug messages.If you want to test something specifically  please mention it.

Persistent download notification on Galaxy S3 running Android 4.3
My Galaxy S3 from Sprint keeps showing me that a file (a picture) has been downloaded. I deleted the downloaded file after a day or two, yet the notification still pops up and when I tap on it, it says item not found.  I believe there is a bug in the software that this keeps happening. How can I get rid of this?
Note: I don't want to get rid of download notifications at all, just this one.

Saw this on another site:
Ryan answered 4 weeks ago
I was having the same issue after I updated my Galaxy S3 to Android 4.3.
I think I just fixed it. Here's what I did:

From the home screen, click the Apps icon
Open the "Downloads" app
In my case the files that kept showing up in the notification pull down were in the Other Downloads tab
Click the "Clear list" button at the bottom of the screen

After a restart I didn't get any more notifications.
Source: Just did this myself.

CyanogenMod 12.1 on Samsung i9500 intl caller echo
I've installed CM 12.1 nightly (currently nightly 20151013) and people who call me complains that they have an echo, and they hear them selves.
I already tried the following:

Update Nightly (started at 20151008)
Doing a fresh install clearing all cache.
Flashing the modem with different versions (currently i9500XXUBMG9)
Stop "Ok Google"
Changing the voice recognition to "Basic Google recognition"
Try different ROM (PAC Man)
Edit the build.prop and modify the persist.audio.fluence.voicecall=false

I'm 90% sure that the problem is with the noise cancellation, because when I mute my mic the echo on the other side stop.
This problem did not occur on the stock (4.2.2) I had before moving to CM.
On the stock ROM I had an option to enable/disable the noise cancellation, this feature seems to be missing on CM12.1 ROM.
Do you have any suggestions?
Do you know how to enable/disable the noise cancellation?
Update:
I've installed the stock rom with Android 5.0.1 and everything works well.
Thanks,
Liron

I have the same problem with the same rom just lower the call volume two notches down from the max and it works fine

Thanks for the suggestion, but I already tried it.
It did help a bit, but people kept complaining.
At the end, I un-rooted the phone and installed Samsung`s 5.0.1 version which works Ok.

How to delete SU binaries without root?
My Android device used to be properly rooted, I had root access to things, but the root manager (old version of vRoot, no computer) was a virus. So, I deleted the root program and I was gonna root another way, but I can't delete the old su binaries. I was gonna try and use something like Odin and TWRP to root, or perhaps another method. I have a Samsung Galaxy Tab 3 7' Wifi Only (SM-T210).
How do I delete the SU binaries without root? Maybe using adb? I do not have fastboot.

are you open to flash custom recovery ? also try to install SuperSU from the play store open it if it ask to update su binary say yes and choose normal method ,see if that updates you su binary or not

@lord-ralf-adolf I can't. I tried to update the su binaries through supersu and it said that it failed. Also, I tried to flash TWRP through Odin, but it didn't work.

it didn't flash the TWRP ? you have truble flashing TWRP or you did flash but you din't figure a way to use it to remove the SU binary ?

@lord-ralf-adolf It didn't flash the TWRP. I booted into recovery (with ADB) and it was my usual device recovery. That is meant to root the device by installing the SU binaries but I had the 2 problems. 1. TWRP didn't flash and 2. I still had the old SU binaries. Should I flash the stock firmware? Or will that still keep the bin and xbin folders from /system

so you wanna delete the su binary so you can root again ? your problem is how to regain root access right ?

@lord-ralf-adolf Yes and yes.

did you try flashing this zip file threw recovery ? https://download.chainfire.eu/696/SuperSU/UPDATE-SuperSU-v2.46.zip

You don't need to delete the existing binaries.  If you root it properly they'll be overwritten.

How can I delete cookies for a specific site in chrome in android
I can see 'Settings' -> 'Privacy' -> 'CLEAR BROWSING DATA', but that will clear my browsing info for all sites. I can also see under 'Settings' -> 'Site settings', there is an option to select 'All sites' and then pick a specific site. However, the site that has a cookie that I want to delete is not in that list (perhaps that list is only sites that have more than just cookies set?).
I also tried navigating to chrome://settings/cookies (which works in the desktop browser), but this doesn't work in the mobile browser.

Press the favicon for the site and a pop-up will allow you to change a few settings for that specific site including removing data like cookies, just did it, Android 6.01, works.

In Chrome 108 on Android 13, I have this: tap icon to left of address bar; tap "Cookies and site data"; I see "199 cookies in use" and I tap the trash bin icon, tap Delete to confirm; afterwards, though, it still says "199 cookies in use".

It's been like this for a long time, too - I had the same problem on my Pixel 2XL for as long as I can remember.

Settings → (under Advanced) Site settings → All sites
Select the site you want and under Usage you can clear any stored data, includes cookies. You can also Clear & Reset.
I do not think there is a way to clear only cookies but this will allow you to clear data for individual sites.

Oh I see. Under Site settings, does the site show up under Storage? It's strange that it has a cookie but isn't in the list.

I can only delete data for a specific time span but not for specific site I want

Click Menu (the 3 vertical dots on top right of screen)
Cilck History
Click the Search magnifying glass
Enter the name of the site OR you can be less specific so you pull up EVERYTHING with the site name....Example....you want to clear cookies from www.butterball.com.  Enter "butterball" and all sites, including search pages, will be listed in your resulting History.  (If you want to clear cookies from just one site, put that site's specific URL.)
Click the Trash icon next to each site in the History list (ALL of them)
ALL your cookies for your "blocked" site are cleared
Now try the site...it worked, right???? :-)

I don't believe history entries would clear any cookies. For the site I'd like to delete cookies for I have about 100 history entries...

Currently I have both my Google accounts (gmail, Google+..) on my phone (Galaxy S4, had to link/transfer data from my old phone to my new) and all pictures and information and such gets saved to the old account I don't want to use anymore.
But I still have some important emails on the old account as well as some contacts and such which I would like to keep. Can these be transferred to my other Google account which I wanna keep and have as my primary?
What do I have to do in order to get rid of this old account I don't longer need without losing the data (pictures,  some emails, contacts) which are currently under that primary gmail/G+ account which I don't want anymore?
Otherwise,  is there an option to say "lock/disable" that old account so nothing gets send or saved to it anymore?

Important: Sync your old Google account data between your phone and Google before starting with the following instructions.
You should log in to your old Google account, and then go to Google Takeout, where there are tools to export your account information to an archive (and even you'll be able to transfer all your Google+ circles to your new account).

To move contacts and other info from the old account to the new one, follow the instructions from this article.
Also you can go to Data tools settings page, where you'll find how to delete your old account, in the section Account management. Good luck.

Samsung Galaxy Grand is running out of space
I'm using a Samsung Galaxy Grand and I have not much apps installed: in fact just about 3 apps besides the pre-installed apps, but still I have no space when I'm downloading apps like Skype and Candy Crush.
On the process of updating my phone I get this message, that there is an insufficient space; the phone too shows a lot of used up space. I have an 8GB microSD card, which is hardly used.
Please help me on this.

You can clean junk data from mobile:
Clear App Data
Some apps store a lot of temporary files on the internal memory which can build up over time.  Apps like Facebook, Google Maps and web browsers are particularly bad for this, due to the massive amounts of data they have to manage on a regular basis. Clearing out these temporary files can free up a great deal of memory for your smartphone and can be done by following these simple steps:
Go to Settings
Select 'Applications'
Select 'Manage Applications'
Find the application you wish to clear and press on it
Press the options for both 'Clear Data' and 'Clear Cache'
Another simple way to free up storage space is by deleting all the log files in the device memory.
Just dial *#9900# on the tablet and
select option 2 “Delete dumpstate/logcat” in the prompted menu.
Hope it helps you!!

Please be sure to move all the Media files (Music, videos, photos) in to the SD card. Your internal storage should have a minimum free space as to install applications. Now go to Settings > Storage > Cached data and clear it.
If the problem persists, do  a factory reset after backing up your important data into your SD card. This should work.

I faced the same problem. I've tried almost all the solutions given in almost all the forums. BAD NEWS - none helped. There may be still be a valid/correct solution out there.
However, GOOD NEWS is that there's a way to overcome this problem. Maybe we can call it an 'indirect way' as the problem remains but you can install new apps. Install and run moborobo on your PC. Connect phone to PC through moborobo, and install apps to phone through moborobo.

So, you're also running out of space, but you were still able to install using moborobo?

Just dial *#9900# on the tablet and
select option 2 “Delete dumpstate/logcat” in the prompted menu.
this is awesome!

Try "Clean Master (Cleaner)" App, it might work for you.
Edit: I just realised that the question was asked a couple of months ago!!

Can't download apps from Google Play store via mobile network
I have a Sony Xperia sola in Egypt. I bought it with Gingerbread, then I upgraded to ICS 4.0.4. After the upgrade, I became unable to download any apps from Google Play using my mobile network, and while using Wi-Fi the download is slower than before the upgrade.
I tried all available solutions like clearing cache or clearing data from Google Play or Google Services Framework, in Settings -> Apps -> All. How can I fix this problem? As it is very serious, many times I'm at places without Wi-fi and I need to download a missing app, or upgrade another one.

Have you checked your APN settings are correct? Have you set it to 'GSM/WCDMA preferred' by default?

This really sounds stupid, but when the time and date are wrong, most Google apps won't work.

Assuming you have a Mobile Data plan or working WiFi connection:

Go to App Info page of Play store.
Clear data and then Clear cache
Then click on Force stop
Now download latest Play store .apk file from this link
After the download, install the Play Store from the file.
Done.

You may have a problem with data connectivity. You can check this (See, for example, here)) by either

Looking the type of your data connectivity in
settings -> about phone -> status -> mobile network type
Consulting the icon indicator on top. H+ and 3G should allow you to download apps.

It you are not on a fast network it may be that the APN settings are not correct for your carrier or that your account is not defined correctly with your carrier. For APN settings you can consult your carrier, its web site or an app (look for APN and your country name). For account definition you'll need to consult your carrier.
WiFi maybe slower because 4.0 is heavy on the Xperia sola because it only has 512MB RAM. You can watch the RAM load with an app such as Android system info

If nothing works just go to Google hangout installed on your devica and sign in and signout 5 times,then return to playstore and try downloading any app,it might work. I called up the google support team and got the issue fixed in this way.

When will my phone get the Android 2.3 update (Gingerbread)?
Android 2.3 (Gingerbread) SDK was released on December 6, 2010. (High-level user highlights)
Of course, not all devices will get this update right away and others won't get it at all. Each manufacturer and carrier often choose to add their custom modifications which tend to delay the official release.
When will each device get Android 2.3, either officially or unofficially, if ever?
See also:

When will my phone get the Android 2.2 update (FroYo)?
When will my tablet get the Android 3.x update (Honeycomb)?
When will my device get the Android 4.0 update (Ice Cream Sandwich)?

Related: Why aren't the manufacturers updating the phone to the latest Android version when it's available?

This community wiki will list all of the known and rumored dates for devices. If you have an update make sure to follow the format that's been established, and the following guidelines:

Keep phones in alphabetical order listing the manufacturer and model
Specify if the date is confirmed or rumored and link to the source
If there is an unofficial release, link to the site where it can be downloaded
If a new update comes out (e.g. 2.3.5 over 2.3.4), link to the new and don't keep the old information

Note that devices that do not meet Google's Compatibility Definition will not receive a Google-sanctioned update.  In the case of the major manufacturers and many others, that means they won't release an update at all since Google's certification is important to their business.

I don't think it's necessary to include devices that ship with Gingerbread. The main reason for this question is to short-circuit all of the "when will {phone} get 2.3" questions. No one will ask that about the Nexus S.

What can you do with Samsung Kies for Android phones?
I only recently managed to connect my Galaxy S with Kies via USB. And I've upgraded it to Froyo 2.2. What can you do in Samsung Kies other than upgrading your firmware. I've seen the interface and there doesn't seem to be a lot of interesting that you can do with it

As you noted, you can upgrade the device software.  You can also back your contacts, text messages up, and you can sync photos or videos/movies both ways.
You can view movies from your phone on your pc directly, that goes both ways; watch from cell on pc and from pc on cell. I believe you also can download apps from kites onto your cell but that doesn't work anymore because of google's market policies.  Apparently, you also can make your cell work as a modem, but I didn't try that so...
Anyways, as edelcom and mru said before me it still needs some work to live up to what it should do and to keep up with handset itself.
Lastly, in samsung defense, kies isn't just for androids, it's their software for the whole cellphones lines, and many users are happy with it, obviously not us, android handsets' owners.

But the thing is, other than checking for and loading firmware through Kies it's actually far easier to do all that without Kies. All my contacts and calendar are constantly syncing and backing up to Google Mail, I can already just drag and drop movies between phone and pc, and the Samsung Apps link on the phone works, whereas the one in Kies is for their legacy non-Android phones. When you have the Froyo update you can use Android's built-in tethering to use your phone as a modem, none of this needs Kies. Once Samsung start using OTA updates I'll uninstall Kies as it will have no further use.

Yes, I agree to all of that, and I, also, don't use it at all, I just tried those things out for the sake of answering the question.
The question is; do you really think that Samsung will do OTA updates?! I hope so.

Basically you are right. You may use it for synchronizing your data between the mobile and the computer, but nobody really wants to do so with such crappy kind of software.

I think you are correct . At least I don't use KIES for anything apart from upgrading the firmware.
Lately it's better, but I think that the KIES software is far from the quality of the Galaxy phone and it's operating system.

I had to install kies because i needed the samsung-win7-usb-dirvers, that are neccessary to connect laptop to internet via cellphone via usb. found no other source where i can get the drivers.

This software may be used for:

Data backup
Data transfer (between a Windows or Mac PC, and a Samsung    mobile
device), limited to certain media file formats
Multimedia    (audio,    photos, video, etc.) management, but limited
to certain file       formats; for example, Kies does not recognise
.avi files
Purchase/acquisition of additional or special device    features
Device     firmware and operating system (OS version)    upgrades

When should I start charging my Lithium battery?
The comments in this question say that I shouldn't wait until low battery charge level before I charge, because that reduces battery life (this is contrary to my understanding before that the faster we charge (without waiting for battery to discharge) the worse it will be for battery life). My question is, when I should generally start charging to avoid this effect? 20%?
Interesting question: If we always limit the usage of the battery only 20% and above, won't we, in effect, reduces our battery capacity to 80%, because we will only use the battery in 20%-100% state?

Related: http://android.stackexchange.com/questions/1020/does-constant-charging-harm-my-cellphone http://android.stackexchange.com/questions/2997/do-i-have-to-charge-my-phone-before-i-use-it-the-first-time

This is not endemic to Android phones, either. See this post on the Electronics and Robotics Stack Exchange: http://electronics.stackexchange.com/questions/7992/does-leaving-a-cell-phone-on-charge-all-the-time-weaken-the-battery-and-why

Al Everett's linked question has an excellent answer - very detailed explanation of modern lithium battery care.

http://batteryuniversity.com/learn/article/how_to_charge_when_to_charge_table

As soon and as often as you can. Spending time at any extreme of charge (high or low) can damage lithium batteries. High charge isn't that bad, considering how quickly modern devices will drain away from that state. Spending time at lower charge levels will damage the internal structure of the battery though.
Draining to "0" on the device won't actually immediately kill the battery though -- the battery protection circuitry will prevent it from going down to critical levels. But the more time you spend at lower charges, the more cumulative damage you do and the more time you take away from the lifespan of the battery. Do the best you can to avoid this, and you'll likely have a battery that still gives you 70-80% of it's life by the time the device is considered obsolete.

So you mean I should always connect my phone whenever I have access to a charger or a USB port with cable? Boy I thought this reduces battery life.

Yes, connect it every chance you get.  It does not reduce battery life.  That is only on Nicad batteries and you have a li-ion.

Exactly - charge whenever you have an opportunity. The only time you're likely to run into a NiCad (last tech that had significant memory effect) is in cheaper cordless power tools.

... and some digital cameras.  Most of those look like two AA batteries tapped together because they are two nicad AAs taped together.

I haven't seen that in a digicam in awhile - just NiMH. Shouldn't surprise me for the cheaper ones though. I do remember pulling apart a Black & Decker flashlight recently too that had some NiCads. They died on the shelf, it was DOA. There's a reason we have newer tech these days. :)

Good point, I may be been confusing my Ni based batteries.  Now that I think of it I can't confirm that I've seen a NiCad since my old radio shack rc car (that could only turn by going in reverse).

thanks! another question. Should I always try to wait until it's full, or if I need to take my phone somewhere I can just unplug it without hesitation?

No worries about unplugging early - If you can only squeeze in a few percent charge before moving on it's still beneficial and has no downsides.

Lithium Ion batteries don't develope "memory" like Nickel Cadnuim batteries, so charging every day regardless of your discharge level will not affect the battery life.  If my memory serves me right, because of the way that the batteries are recharged it is less strain on the battery if you don't let it get below 40% but I wouldn't worry too much about it.  In that same respect, don't be hesitant to charge anytime you have the opportunity.

Now there's Chargie - a USB stick+Android app combo that limits charging externally (no root needed). Just install the stick between the charger and phone and use the app to select the charge level. Simple as that. Look for "chargie stick" on Google.
Even if you want to charge to 100% - it will go there but disconnect power completely until charge goes down to 97% (a few hours). Then it will reapply charge, but that's way less stressful than normal trickle charging. However, given today's battery capacities, 90% is enough to get you out of most days.
Disclosure: I am the CEO of Lighty Electronics. We developed Chargie and would love people who have had this issue to enjoy our product as much as we do. No spam, just the solution to the problem.

Samsung s6 edge battery drains super fast at 15%
My battery lasts normally during the day however I am observing a weird issue where when my phone reaches 15% battery warning. It discharges in few minutes which to me is counter intuitive.
I had phone for about a year. I normally last working day without needing to recharge with 50% left. But sometimes if I am using phone a lot it drops to less. I think problem is not with battery but rather with it discharging really fast after warning. It's as if some mechanism starts using more battery after the warning.
I haven't reset phone since I bought it. I don't frequently get to 15% level though, only noticed this behavior recently, and had phone for a while.
I use normal charging mode and not 'fast charging'.
UPDATE: I had a theory that it's 'power saving' mode that was causing this so I changed setting to switch to it at 5% from previous 15% then drained battery and observed and it didn't matter - once battery got to 15% it discharged to 7% in ~3 minutes.
I am sure it's happening to others, why does it discharge so fast? How do I fix it?

@beeshyams suspected the "battery display" might not yet have adapted (it takes a little until the values shown are half-way accurate). With "about a year" of usage, I'd say we can rule that out – unless you frequently factory-reset the device, that is, or often swap apps (i.e. uninstall a bunch and install another bunch).

Is this behaviour seen if you charge the battery using fast charge- as a thumb rule, what charges fast will discharge fast too. So this may be the culprit and you may need to verify by charging in standard mode using a standard charger @izzy: That's all I can come up with :)

@beeshyams that's one point more than I had: no more ideas either.

@beeshyams no I use normal charging mode.

Ahh..that is also ruled out :( , upvoted your question and hope a solution emerges

This was occurring for me as well, and a resolution was reached, although it may not be valid for everyone.
It is the sign of a failing battery, and is unfortunately common in the S6 series. Once the phone goes into Power Saving Mode, it seemed like the battery would drain abnormally fast, sometimes skipping from 15% to 12% immediately.
My carrier (Verizon) claimed that it is indeed a bad battery, and they are aware of the issue. Samsung typically wants you to send your device to them for repair, as removing the case and battery yourself will void any remaining warranty. Thankfully (hah), my device also had a faulty camera, which was close to failing entirely, and Verizon was able to replace my device with a brand new one (not a refurb, which I was surprised at). It was still under a manufacturer's warranty, so I did not have to pay for the replacement.
Regardless, get in contact with your carrier or Samsung, and see what they can do for you. This is unfortunately the only solution that worked for me. All the tweaks and tips from various Android sites were unsuccessful in helping the battery drain.

okay guys i found out the solution it was home run baseball app in mine it must b some app which uses your more battery after 15% left not a battery problem try factory reset if u fail to find out app good luck :)

How to block private numbers
I am getting way to many calls from marketers these days. I have listed my number on no call list and they still keep calling. Most of the time I can't be bothered to report everyone.
How to block callers from private numbers that are hiding their Id?

Per their description both Call Control - Call Blocker and  Call Blocker Gold should work.

On Android version 5.1.1 (Samsung Galaxy S6 Edge)
One way to do it is go to Phone (like you would make a call) then click on the More in top right of the screen and choose Settings then Call Settings > Call rejection > Auto reject list and select the "Unknown" option.

Hope this saves you some time.

It's probably worth [edit]ing your answer to add your device details as these options may not available on all devices (e.g. it's not available on my Nexus 6P).

@bmdixon I have added Andriod version do you think phone model is relevant too?

Yes, I've used Nexus devices for years and none of them have had this so worth adding your phone make and model. If it apples to other devices then people can comment/edit to add other info.

Why is the screen acting weird while charging?
I noticed that when I charge my phone with a cheap charger that I bought from Ebay, the screen acts strange:

It suddenly can't position my taps correctly and
It detects swipes as taps.

After a fast googling the reason is most likely that the charger has a bigger voltage output that the phone expects and that causes the trouble.
Why does a bigger voltage output cause a behaviour like this?

I have a similar problem.  I put In a cheap charger,  my screen starts going mental

My phone used to do that too ;) although I use the charger that came along with it. BTW my phone is Xperia M and thank god the problem got away by itself, I didn't do anything.

It happened with my Pixel 2 using the charger that came with it. It's not the charger as I use it all over the place without problems. It's the mains sockets on Great Western trains.

Problems with ghost touches on the screen while charging is very common when using third party chargers or cables. It is caused by electrical discharge in the form of either current or static charge. I'd toss that charger and/or cable away and buy an original one. Damage might have been cause already though which will most likely be seen by unusual battery draining (it can mess up the  calibration).

WiFi and data connection switches on automatically although I repeatedly turn off the two features
The WiFi feature and data connection in my tablet turns on automatically. After resetting, the problem goes away but as soon as I download programs that I need, the problem comes back. Anyone with suggestions?

Related: Wifi and Data switching on automatically in my HTC Desire 820 device

Either an app that you have given permission to modify system settings is doing this which should be easily solved by checking each of your apps permission settings?
...Or maybe you have something like WiFi "Scanning Always Available"?
If you feel up to it, you may also find more information by looking at your Android's log files (either via an app that can look at the logs or connecting a computer and using "adb logcat")

I deleted Android OS from my Karbonn device
I have a smart phone (Karbonn A50,Android version 2.3.6) which was rooted earlier.
While accessing my files on the memory card, I came to know that I can access the system files and apps:think OS. I've selected all the files and tapped to delete them and got a warning not to delete. On repeated trying, I was able to delete them to some extent and the device got stuck.
Then I removed battery and switched it on. Nothings works. The phone gets stuck on boot logo (karbon smart) and if try to switch it off it doesn't, until I remove the battery.
If connect to PC, it notifies that something has been detected but no device is seen in my computer. I can't access factory reset either.
Please help me.

hmm :( please do help man

You mean you deleted Files from /SYSTEM/ folder.

I would NOT recommend downloading odin from that site. There are plenty of posts and etc on XDA saying that site packages viruses and malware with odin. http://forum.xda-developers.com/showthread.php?t=2712008&page=2 You can find plenty of legit links on XDA for odin.

hey can you please give in detail the process of getting download mode and flashing
thanx!

You can goto download mode by press and hold volume down button home button and power button together! Then when you will see download screen leave keys and follow instruction.

Connect usb cable to your phone and pc

Run ODIN and select rom you downloaded for your deice from above link.

Click Flash and wait. You phone will auto-reboot after complete.

After your OS will load, disconnect usb cable and do setup.

Done! Enjoy........ And hit the UP button of this answer.

Playing web games that require arrow keys without using a physical keyboard
I would like to play some web games like Unikong using my tablet. But the problem is, they require a keyboard, or specifically, the arrow keys in order to play.
I know I can connect a mouse and/or keyboard via OTG and play, but I don't always have access to them.
I have Hacker's keyboard (has arrow keys) but the game registers my arrow key inputs only sometimes at irregular intervals. This happens not only for Unikong, but other similar games too (I remember creating a small JS canvas game myself that it works fine on the PC, but not with hacker's keyboards' arrow keys). Here is a GIF from where you can see the problem (Sorry for the low quality 5 FPS GIF):

Note that this happens on some games only. For example, this problem does not exist with Chrome's T-Rex game.
So, how do I play web games that require the use of arrow keys using my Android tablet without a physical keyboard?
I'm running a rooted Android KitKat 4.4.2

Game Pad seems to meet your needs looking at the play store video ( I don't play games so not sure if that's what you want)

@beeshyams Unfortunately, for some reason, Game Pad's permanent notification doesn't work. I can't see any notification even though I've enabled its 'Permanent Notification' setting. So, I can't open the keyboard to test it.

How to start Chrome's T-rex game from an Android tablet?
I can't start Chrome's cute endless T-rex running game from an Android tablet. On a PC, pressing Space starts the game while for an Android phone, I can just tap the dino to start it. But I can't figure out how to do the same on an Android tablet!
I've tried tapping, holding, swyping, and what not but the game doesn't start.
So, How do I start the T-rex game from an Android tablet?

I'm pretty sure you can connect a physical keyboard and press space to start it, but I don't have a keyboard to test it currently and so, I'd appreciate it if anyone could verify this and post an answer.

are you sure , that youre running chrome's latest update?

Yup. Version 56.0.2924.87 now and Play Store says its fully updated.

One way to do this would be to install a third-party app called Hacker's Keyboard.
Then, enable the keyboard and set it as the current input method. Also, check the box against the 'Use permanent notification' setting under 'Input mode settings' in the Hacker's Keyboard settings.
Now, open Chrome and make the dino appear by, say, by enabling airplane mode and visiting any website. Tap on the permanent notification of Hacker's keyboard and press Space.
Voilà! The game will start. Press Space or ↑(Up arrow key) to jump. Oh, and Enjoy! :-)

Is there any sniffer aplication for Android 2.2?
Is there any network sniffer program for Android 2.2 similar to Wireshark for Windows?

There is Shark that does just this, it requires root, there is also Pixie, but it too requires root.

There is also Packet Sniffer By AndroidArts
and For Facebook and Youtube...Try FaceNiff...
Also there is DroidSheep (just like Firesheep) , "Network Spoofer" which uses Debian Image and "Arpspoof" is also good app.
PS: Use Shark For Root Instead of Shark Native

If you had root access to your phone, there are many package sniffers on the market.
Some free are:

Unknown error code during application install "-24"
I just updated my Moto X to latest and greatest Android 4.4 KitKat (I even did full factory reset just to be sure) and now I'm trying to install WhatsApp Messenger but unable to do so, I'm getting following error:

Unknown error code during application install "-24"

Please advise.

According to a thread on AndroidCentral, this is a problem with either...

the app itself having trouble to update an already installed version (unlikely after a factory-reset) → uninstall first, then try a fresh install
certificates not being handled properly → install from a different .apk (e.g. one from your backups, if you've made any, or from an alternative source)
certificates (variant 2) → Go to Settings→Apps, select the "All" tab, scroll to Google services framework, tap the entry, "clear cache", "uninstall updates". Repeat the same for Google Play Store, then reboot, then try again

I didn't verify this (don't have the issue, so I didn't even have the chance to), but it sounds reasonable.
Additional sources on this error:

Unknown error code during application install: "- 24 " (XDA Developers)
App description of the PocketTool App:

The -24 error is a killer. People think it is because of PocketTool when it is actually the device. You may want to include in the description that if they get the -24 error to reboot the device, then try reinstalling mcpe. If that doesn't work, uninstall all apps that could be used to modify the game, reboot, and try again. If even that doesn't work, the only other option I am aware of is to back up important things such as Kindle books, music, movies, and saved app data on something (I used my laptop) and do a factory reset. If they are on Jelly Bean, then they will get a -24 error if they try to reinstall mcpe after a failed mod install.
Users had the same trouble with Spotify. A second factory-reset solved it.
A thread on Android-Hilfe.DE (German) again supports the first variant of my answer (remains of a previous install). Maybe your factory-reset did not complete cleanly.
A Google search on "google-play error-24" reveals even more sources.

Use Titanium Backup to delete the orphan app data, then install the application again. That should fix the issue, but you'll lose all of the user data for that app.

Download the app Master Key multi-fix. You can think of it as a plug in. But as soon as it is installed on your phone, you should be able to download the apps that had the error 24 notice. Hope this helps.

If you are not rooted and don't want to root your device, forget about this app because to install it a prerequisite is something called Xposed Framework (which in turn requires root)

Dude, try this one, don't have to install an apk or reset your device, just delete via root explorer file named com.whatsapp in dir data/data/com.whatsapp
Then install your whatsapp again from playstore or apk directly

That would require the device to be rooted, which is not stated in the original question.

Remove application and set to factory setting. Mine works now.

What to uninstall – after a factory-reset? A factory-reset includes removing all user-apps and their data, so there's nothing left to uninstall.

Always seeing "No connection: Retry" in Android Market
I have an HTC Touch with Froyo installed that I use for app development. I haven't used it for a couple of months, and when I fired it up today I'm seeing the same error every time I launch the Market app: No connection and a Retry button. It doesn't matter how many times I hit Retry, I just end up back in the same place. The phone definitely has a solid Wi-Fi connection though and all other online apps (browser, Twitter, etc.) are working well.
I've tried force stopping the Market and restarting, clearing its data and uninstalling updates, all to no avail. What can be causing this error?

The answer is that the date/time settings were incorrect. The device had been off for so long that the clock had reset. Once I set the correct date and time the Market app ran normally.

Found the answer in an Amazon forum after a lot of searching. Just thought I'd contribute it here too. :)

I have had the same issure, but correct date / time. My solution has been to Turn Off/On the WIFI, works every time!

I had this problem once and it was because I was running DroidWall and I forgot to whitelist the Market app.

just clear your data and restart your phone

You might like to give more information on what data exactly you think Mark should clear, and how.

Try clearing cache and data for the Market app. You can do this by going to menu>settings>applications>manage applications>all and scrolling down to the Market app then using the "clear data" and "clear cache" buttons.

Yep, did that as I said in the question: it didn't make any difference unfortunately.

Backup my Android without my Apps, Settings, Config's, etc.
As the title states,
Is there a way I can backup my phone, without including all the extras, that I would just prefer to pick and choose to install later.
feel free to read the whole thing, or just read the bold as the bold summarizes most of what I am looking for. As well as the bottom explaining my device & set up.
The best method I would think of, to do this, would obviously be to do this after a factory restore, and data wipe. But considering I am way past that point, I am trying to find another method.
I already backup all the applications I need, using Titanium Backup, so I don't want to backup my apps that will probably be different at the point of recovery, or will have certain apps I ditched before the point of restore, or have certain configurations I don't use/need/etc. I could go on and on. But the point Is I would just like to backup my stock rom, kernel, with my Super User privileges, without anything else. So I can basically use it as a factory reset, by just flashing my rom.
The main reason I ask this, is because I tend to get big into customization. Recently I used a font installer, form Rom Toolbox, and basically bricked my phone by getting caught in a boot loop. It would never pass to boot animation. So I had to use an old Odin Image with Clockwork Recovery. That was all I had. Luckily that fixed it, but I would like to make my own recovery images.
But, really the best thing I would just love, yet I am not sure whether it is possible, or as customizable, is it would be great if their was a way to just pick and choose what you want, or don't want to backup to a single image file.
Like an application that lets you choose certain things:

System
Root
Kernel
Applications with or without caches, data, accounts, and settings, etc.
System Settings
Account Settings

...you get the point...
Now there wouldn't happen to be something like this for backups would there? Or is that just a dream of mine?
Even though right now, I would prefer to just backup only my system without everything else, like apps. Maybe one day in the future I may like to be able to backup other things as well. Which is why I ask. Might as well use a "one backup to rule them all" method if it exists. But if not that's fine, I could always just backup the system itself, and continue to use Titanium.
Now that, that is covered, what are all the different methods of backups? Odin. Nandroid. Anything else? What do they cover, and how customizable, etc.
Ive been looking into this for the past week, but I am having trouble finding something that is relevant to what I am looking for. And all the information regarding backups seems quite specific to certain devices, and custom roms.
Which puts me kind of at a fallback, as I have a pretty uncommon device, with a pretty default rom.
I have a Samsung Conquer 4G (SPH-D600) With the FE16 firmware update, on a stock rom with root, with a slight mod of having ClockworkMod Recovery.
So when I press and hold the: "Volume Down, & Power button" it takes me to a "ClockworkMod based recovery mode" (according to what it says on the header on the screen.)
So that's what I am working with.
Any thoughts on this selective backup utilities I am thinking off? Any good resources I should look into on this topic? as well as any other information you may find relevant to this situation that you would care to share?
I would greatly appreciate any input on the subject, as android backups aren't a topic I know much of anything on, and cant really find any good resources on the subject myself.
So any and all help is appreciated. Even just links are great. I enjoy reading for myself.

Odin is not a backup utility, its rather more of a means to flash boot/recovery and the rom itself. So that's one off the list. :)
Use CWM to backup the entire handset to SDCard - this includes, boot, recovery, system, userdata partitions. Easy and much quicker to restore from! The latest Titanium Backup can do a restore from a nandroid created by CWM.
Can you include a screenshot of this "ClockworkMod based recovery mode" as that does not sound quite an official CWM and hence would be slightly concerned. Official CWM would have this as shown below! Note the lack of the wording 'ClockworkMod based recovery mode'.

To perform the backup, use the Volume down key to scroll down until you reach 'backup and restore' as shown:

Hit the Home key, to bring you to this screen, the highlight bar is on '-Backup' for some obscure reason, the screenshot failed on this one so no screenshot, hit the home key again to start the backup process.

When you do a restore, it will erase boot/system and userdata, and does the job in dumping everything back in place. As if nothing has happened next time by rebooting within CWM. Consider this as a equivalent of a Windows System Restore Point, cannot go wrong there.
But ultimately, what you're asking for, Titanium Backup does it quite nicely. See the screenshot below, where there is a list of apps and can choose which to backup/restore.

Here's a menu option to do the extraction from a CWM backup.

Ultimately, it is up to you how to do the backup, pretty much in the same way doing a backup on Windows, the strategy used will depend and vary, to each and to their own. Personally, as I experiment a lot with ROMs, I do a straight nandroid backup, then get down to flashing another ROM and if I don't like it, I can go back to CWM to do a restore.
As for Settings etc, I ignore them, as that can be a minefield which may cause a ROM's apps to force close so I disregard them and selectively choose which apps I wish to backup.
Using the two combined can be quite potent means of backing up.
Edit:
This question - how you managed to take a sreenshot of CWM? If I'm not mistaken, it is run at the boot point making it act like a "BIOS" in terms of PCs. So how did you do it?
The recovery is identical to Android's ROM running from /system, it has its own kernel, near identical to the one used when booting into /system. The recovery has the init.rc script heavily modified to not to start up the Android's services that makes up the standard familiar environment. In fact, if you were to peek into the init.rc, it executes one program, called appropriately enough recovery which is what you're seeing here.
When the bootloader runs, its like this in English pseudo-code

load kernel from boot partition at memory address.
If Volume Down key is pressed then
read from recovery partition's kernel and chain boot load mechanism (read recovery's kernel into memory address, and jump into the entry point of that kernel and start running, overwriting the previously loaded boot kernel) and execute run scripts to bring up recovery program a lá CWM and hence in recovery environment
else
continue to run as normal reading from system partition and execute run scripts and bring up services a lá Android OS and hence in system environment.
endif

So quite clearly, there is no difference behind the scenes, the kernel, shell scripts, etc.
As to how to obtain the screen-shots, that is a specialized script specifically for the Zte Blade and using the linux tools imagemagick command line utilities involving ffmpeg and mogrify, it is hardcoded to use the resolution of the screen for the Zte Blade, i.e. 800x480, and using adb to pull in the framebuffer, pass it into ffmpeg, and flip it over. IIRC, it does not work on any other resolution and depends on the kernel itself if it has framebuffers compiled in.
#!/bin/sh
adb pull /dev/graphics/fb0 fb0 && ffmpeg -vframes 1 -vcodec rawvideo -f rawvideo -pix_fmt rgb565le -s 480x800 -i fb0 -f image2 -vcodec png $1.png && mogrify -flip -flop $1.png && rm fb0

Humm... Can you reduce the size of the images on your answer? My 22" monitor suddenly doesn't feel that big ;)

Oh...... hummm... gimme a few mins ;) lol! lucky you have 22", mine is 19" :P

Better now that its smaller, should make your 22" still feel ahem big? :D

Now it's kinda small :D +1 t0mm13b, Nice answer!

cheers, great :)

May I ask @t0mm13b how you managed to take a sreenshot of CWM? If I'm not mistaken, it is run at the boot point making it act like a "BIOS" in terms of PCs. So how did you do it?

@ShedoSurashu refer to this xda forum thread.

@t0mm13b Thank you, Thank You Thank you!!! Thank you so very much!!! I appreciate that big time!   But by backing up like that, wouldn't that save all my applications with the backup? I dont want to save the applications, so can I backup using that without the applications? Because the apps will make the backup huge, plus most are on my SD card, and like I said, my apps change daily, so to restore from my backup will have tons of apps that I will need to remove anyway..  Heres a the screenshots of mine. http://i.imgur.com/dEvssh.jpg  &  http://i.imgur.com/WJTJFh.jpg

So people who want to backup before flashing CWM are out of luck...

Samsung Galaxy Tab 2 infinite login redirect with 2 step authentication
I've just bought a Samsung Galaxy Tab 2 and tried to login with my google (gmail) account (which has 2 step authentication) and it redirected me to the web login which I completed (with the text message for the code because it's an unrecognized device). It then returns me to the OS login which I try again which then redirects me back to the web login.
So I get stuck in this infinite loop when trying to login. I assume that this is because I've got 2 step authentication enabled. Any idea how to login in the Samsung Galaxy Tab 2 with 2 step authentication?

You should try to set up an "application specific" password for your tab, and enter THAT password when you enter your account details.
Now you totally avoid the second screen asking for the code.
You can create an application specific password at
https://accounts.google.com/b/0/IssuedAuthSubTokens (at least that's the one I use)
Kind regards
joern

He already has it.

You can temporarily turn off 2-step verification, and turn it back on after you have logged in.
I had the same issue with Galaxy Tab 2, and did just that.

Is it "safe" to provide users with the apk file?
I was wondering, if I have an app that is available on the Play Store, is it "safe" to provide a direct download of the apk file to someone (either signed with the proper keys, or just debug-version)?
"safe" in the sense of does the marketplace do anything special to the apk to protect the source code, signing keys, etc.?
Reason I ask is a user of my app has said that their Marketplace/Play Store is no longer working and therefore can not upgrade the app - so asked me to email them the apk file.
The app is a free app, so on the surface I can't see any issues - though just wanted to double check.
Although this raises the question - the apks of the apps you download from the marketplace (paid and unpaid) are on your phone. Are these apks (on the phone) somehow unique to the phone/google account? Otherwise, what stops one from buying an app and passing that apk on to others?

@Power-Inside However, it is talking about Google Play and APK's from a developer perspective.

Yes, I wasn't quite sure where to ask the question, here or stackoverflow. But since there was no code, and is very Android specific decided to ask here :)

Protip Do not upload debug apks - that's a moth to a flame - people will know exactly what is going on with the source and will rip you off and pass it off as their own work. Use proguard, but since this is android enthusiasts stack exchange, head over to the sister site StackOverflow to find out! :)

Signed or not, someone can always decompile the application(.apk), that's why it is very important to use Proguard.

There is nothing dangerous about it, and this is done occasionally when the store isn't accessible.
In response to your second question, apks are not unique - and can be easily transferred to another device, or the internet. This is the base of android app piracy.
When you upload the APK to Google Play, GPlay does nothing to it. It is up to the developer to obfuscate the code, to prevent decompilation.

As Liam already pointed out, there's no danger involved for the developer. If one wants to grab the .apk for distribution, that's easily possible using apps like AppMonster, which can back up the .apk file to SD card. No extra protection from Google's side -- except users might feel more safe installing it from a "trusted source" (and they are right about that at least when it comes to unknown/new devs, as the Google Bouncer adds a protection layer against malware, see Android and Security).
In fact many developers hold their apps .apk files available on their project site for good reasons. One you already mentioned in your question: Playstore might have (temporary) problems. Moreover, not all devices are able to access the Playstore (and thus could not use your app if it would be available only there). Another good reason would be to provide "Beta versions" this way, so as a dev you can get early feedback without running the risk of negative feedback on the Playstore.
To sum up: At least for free apps, I'd even recommend to keep a direct download link to the .apk available, if possible.

"Safe" from who? "Safe" opposed to what?
If your app is "nasty" (an app for crime), you can not count on a solution which "hides" the executables (such as Google Store,) due to; antivirus businesses can use adb (https://stackoverflow.com/questions/4032960/how-do-i-get-an-apk-file-from-an-android-device/18003462#18003462) to move the executables to a personal computer do analysis,
or can use WireShark/Snort (https://manpages.org/snort/8) to clone Google Store's protocols (to produce a version of Google Store which does not install, but, just downloads the executables) to do analysis.
If your app is a "game" (you want to "hide" the executable to prevent abuse,) cheaters can do just what antivirus businesses do, but you have a solution; do not use the client to store/process important attributes, but, have your server store/process all important attributes.

Is harmless to offer executables of your apps, if you wish users to install your apps.
[It is unsafe to install an app unless you submit it for analysis -- to services such as https://virustotal.com -- which is not possible without an executable to submit for analysis.]
[Google Play Store is unsafe, for various reasons]

I don't understand why "Google Play Store is unsafe" from the POV of the developer/provider of the APK, which this question is about.

Such an unsafe ecosystem is unsafe to the developer (as opposed to just unsafe to users) due to trickle-up effects (https://wikipedia.org/wiki/Trickle-up_economics); if the whole internet becomes infested, the developer does not have access to hosts nor to users.
Suggest to use an actual package manager (such as https://wiki.debian.org/Aptitude, which https://play.google.com/store/apps/details?id=com.termux -- Termux is the one possible exception to "Google Play Store is malevolent" -- has) or an app store based-off such (such as https://f-droid.org/)

HTC One Deactivate Autocorrection
Is it possible to deactivate the autocorrection feature of the HTC One (Android 4.3) without losing the 'swype' feature of the keyboard?
I could only figure out how to deactivate the 'swype'-, wordprediction and autocorrection feature all together.
What I would like is to deactivate just the behaviour that unknown or uncommon words get corrected.

Go into your Settings/Language & Input.  Under "Keyboard & Input Methods" hit the settings icon next to your keyboard.  Scroll down to "Text Correction" hit "Auto Correction" and select "Off". That should do the trick.

Device won't wakeup from power button
I used a Navigator app that prevents my device (Galaxy S2 with Cyanogenmod) from turning the screen off while plugged in. But at some point I could no longer wakeup the device screen with the power button anymore. The only thing that wakes up the device screen is to plug it into a USB charger. This behavior continues even after uninstalling the app. The device is not turned off, it's just the screen wakeup from the power button that stopped working.
I assume that the app overwrote some settings.
I couldn't get any help from developers of app.
Thanks for any help!

If you unlock the developer options (if not already unlocked with Cyanogenmod), there is an option "Stay awake" that will keep your screen turned on when plugged in.  You can try using that and see if it will revert any settings that the app might have changed.
See this website for a brief explanation on how to enable developer options.
If that doesn't work, you can "remap" the power button back to the power button.  Check out this guide to remap the buttons on your phone.  Hopefully it won't come to this though

Thanks for the adive. Unfortunately it didnt work. Only when the USB charger is plugged in, the screen will wake up.

How to set up priority mode in Android 4.3?
I have an Android 4.3 phone and don't expect any Lollipop updates soon. However, Lollipop's "Priority Mode" is a feature that would be tremendously in my daily life.
Specifically, I expect the following:

Phone rings only when receiving calls from specific callers, otherwise stays silent
SMS notification sound only when receiving texts from specific people
GMail notification sound only for mails from specific senders

To achieve this, I came up with the following "solution" so far:

Ringtone: I set the default ringtone to none, then set the actual ringtone for the specific contacts only.
SMS notification: Haven't found anything useful here...
GMail notification: In the GMail web app, I set up a filter that adds a label to messages from specific senders; then in the GMail Android app I set the notification sound for those labels. I turned off the notification sound for my inbox in general.

The upside of this solution is:
It works (more or less). It was rather easy to set up, because we're talking about just 3 "priority contacts". I didn't need to install any extra apps, which sometimes complicate things and maybe cost money.
The downside of this solution is:
I don't see any easy way switching between "priority" and "normal mode" -- I had to set both the default ringtone and GMail notification sound by hand. Also, SMS are not prioritized, but that's not so much of a pain, because I don't receive so many texts from "less important" people.
My question:
Generally, what would be considered "best practice" to set up priority mode (in this case for phone calls, SMS and GMail) before Android 5.x?
Is there any way to set custom notification sounds for SMS from specific contacts? Or is there any recommendable app which allows to do exactly that?
Or better yet: How could I easily switch between "priority" and "normal mode" without having to change settings in three different places -- is there any app which handles phone calls, SMS and GMail altogether?

That ringtone part is covered here by an app. Anyhow, ringtone and sms can easily be covered with Tasker or perhaps, with some other automation app too. I don't use GMail so can't comment.

@Firelord I edited the question to reflect the exact Android version.

In case Tasker covers contact-specific GMail notifications, this would probably make a good answer -- has anyone tried that? In either case, it would be interesting if there is a free solution as well...

Hacker's keyboard v1.38.2 doesn't show any suggestions other than "Android"
I downloaded and installed Hacker's keyboard v1.37 some months ago. It was functioning as expected and the experience was great. Then, I upgraded it to v1.38.2 and set the settings to the same for what I had for the old version.
The problem with he new version is that it doesn't show any suggestions. The only suggestion that I see when typing is "Android" and nothing else.
What do I need to do in order to fix it?

It seems that the dev has decided to seperate the keyboard and the completion dictionary. Download and install the completion dictionary by searching pub:"Klaus Weidner" in the Google play store and then, the suggestions will appear.
Quote from the Hacker's keyboard app description:

Completion dictionaries are provided by plug-in packages, see the "other applications by this developer" section for the currently available list. The keyboard also supports use of dictionaries (but not keyboard layouts) provided by AnySoftKeyboard language packs.

Quote from the English completion dictionary description:

In the future, the English dictionary will no longer be included in the Hacker's Keyboard package. Use this external dictionary to provide English completion suggestions.
An English completion dictionary for use with Hacker's Keyboard. Needed for future versions, release 1.29 still has  it built in but I plan to unbundle it to save space.

Assuming that your contacts are synced to some service like Google or your mobile carrier, you should be able to do that right through their website (or Gmail, if all of your contacts are synced with your Google account). Any changes you make in your account on a PC, including contacts, will automatically sync to your device.

via USB of any device with Linux (not rooted device)
Need to change some files in the system folders...

As I said in my other comment: Try adb.

If you're not rooted you can't do this. /system is read only and you can't remount without root.

The best way is relative and dependant on not just hardware but also your desire to modify and or automate. For one-shot tasks I'd suggest adb & for special projects and automation I'd suggest Casual or Xposed. For messing with stuff I probably shouldn't, I'd definitely start with Xposed if I were you because the settings can be non-permanent.
To help future answer attempts try giving us a bit more info on your setup; Linux distro & CPU 32/64 bit, Android model & OS/Kernel versions if added to your OP will help better narrow down the best answer quickly. Additionally while looking into ADB you may wish to also look to the C.A.S.U.A.L. project as the tools there may allow for shortcutting lots of the driver and SDK installation hunting time down as well as enabling custom scripts that fire when you plugin your Android; very simple to understand language and very powerful under the hood.
ADB The Android Debugging Bridge will be the command line interpreter that you'll want to become familiar with. Commands are not hard to understand; push and pull files or directories is fairly straightforward. Mounting the directory as read/write and remembering to reset those permissions correctly can sometimes lead to trouble; make backups first with pull & try not to push where you shouldn't.
'Android SDK Tools' is the software suite that you'll usually need running on Linux to make use of push & pull commands.
Be sure in your Android's settings that you've got USB debugging enabled; sometimes this needs to be revealed by repeatedly tapping 'Build number' within the 'About device' section and then pressing the back button and the 'Developer options' should have become visible in your Android's settings screen.
Installing the necessary drivers and software packages is Android device and Linux distro specific. Some Android's drivers are not available online for Linux and require much work, others are happy enough to talk to a PC that your distribution may already be capable of basic file read/copy operations of protected file systems but unable to push without the Android SDK.
Installing the Android SDK Tools is a whole different can'o'worms when both Linux distro and Android version has to be taken into account. The route I would take would be booting a pentesting distro and installing to that anything missing for Android USB hacking as the tools that these distros offer may give you options to make full backups any time an Android device is plugged into it as well as run tailored exploits that keeps your Android's system synced with the wishes you have.
Depending on the files you're trying to modify you may run into issues with checks run by other apps or you may need a special compiler to be sure you don't brick it by killing your radio's firmware... backups don't really help there or if you mess with the bits that read your power button such that... most call that a 'brick' I call it 'spare parts' when I get a device that really doesn't respond. As stated in the beginning of this response best is relative to what you're trying to accomplish and on what hardware you're rocking. Lastly when embarking on a Modding expedition it's a good idea to know how much a refurbished model will cost, two Android devices that I've come to really enjoy boot-looping is less than $40 to have shipped (even less for ones that work but don't have a screen) and the refurbished devices I use during testing phases of development while my main device holds the most stable modifications only after I've repeatedly boot-looped the refurbs. This method has allowed me to mess with parts of the Android system, locally at times, without to much fear of perma-bricking something that I've invested data into.

All of the above being stated if you're not opposed to root then the Xposed module loader and their documentation on how to make your own module for Xposed may be useful for making modifications on the fly that automatically revert (ie not load mods on boot) settings if a bad shutdown happened last. The framework allows for modification of nearly every process of your device, often without the need to reboot to see settings take effect, so it is not for the faint of heart... used correctly though you can hide root (SU) permissions access from the rest of the Android system, root? what root? and used incorrectly it can hide it's own presence while slurping a victim's dastructrueta. Though the same feature also allows for covert data collection after device theft as well as faking the shutdown so really this yet again comes down to user's wishes for their device's features or functions and what syntax structure you feel comfortable tackling first.
