I recently purchased Minecraft PE for Android to join my kids who play on PC. I paired a bluetooth keyboard and mouse and though I was disappointed with the lack of true mouselook, it worked well enough.  Yesterday however when I tried to play the keyboard no longer seemed to register all the keys. The "W", "A", "S", and "D" keys no longer work to move, yet "E" still opens the inventory. Worse, attempting to remap any of the keys in the settings doesn't seem to work either.  The arrow keys seem to work for movement, but they are too far from other keys to be practical. Curiously, holding the control key to run and pressing any of the "W", "A", "S", or "D" keys causes the player to run continuously in that direction, even after the key is released.  In reviewing old bug reports (MCPE-10353) it seems like this exact issue was present in earlier builds, but the bug reports indicate these issues were fixed long ago.  I'm not sure why these issues suddenly manifested again, but I am wondering if the recent update from 1.8 where things were working to 1.8.1 has reintroduced this bug.
