Remote physical keyboard support in PPSSPP for Android

[Uszasty]

Yeah, I know this is very specific, but here is my problem: I cannot properly use remote physical keyboard(Xperia X10(mimmi) connected to Xperia E1 via DroidMote). What's weird, I can assign buttons in options, but I cannot use them in-game. Can you help me?

DroidMote gamepad function works as intended(can use it ingame), but I didn't want to use another phone if I need to use touchscreen anyway.

Exactly the same problem with USB OTG connected Keyboard.
