Problems with game settings inside the keyboard layout

I use my cell phone is millet 3 MI3C.
Game settings inside the keyboard layout, click Customize, and then go inside and make yourself at one, then back to the default one, you press the back or return on your phone it will always return to first go to settings, or modify the game ID to that place!
And quit the game often appears, Minercaft-Pocket Edition has stopped running.

I have recorded the video download link: http://share.Weiyun.com/e881afb7dc72f8cdd1a896bf205737e5 (password: CYku)

This is phone report!
