Can one import FENs of positions involving checkmate into Droidfish? I recently copied the following curious position (from this answer) to clipboard, and tried pasting it in Droidfish.
3b1q1q/1N2PRQ1/rR3KBr/B4PP1/2Pk1r1b/1P2P1N1/2P2P2/8 w - - 0 1

However, the situation involved a checkmate and when I tried pasting it, Droidfish displayed an error message (King capture possible).
My question
So can't I load the FEN of any position involving a checkmate in Droidfish?
Apparently the FEN is wrong. In the position it should be black to move next, so in the FEN there should be a "b" instead of "w". The correct FEN would be: 

3b1q1q/1N2PRQ1/rR3KBr/B4PP1/2Pk1r1b/1P2P1N1/2P2P2/8 b - -
