When you connect a Bluetooth keyboard to your device and open Minecraft you cannot move around using w,a,s, or d. Also, when you connect a mouse and try moving it around in split controls, or non-split controls it does not it does either. To fix this you have to click and drag for it to move the screen to move around. I am okay with it not moving around in the non-split control version, but the split control version should not have to be moved around. If this is changed then you would also have to be able to use the escape key to exit out playing.
