Since the 1.19.40 update, a problem occurs when connecting an Xbox controller to my mobile device (I don't know if it happens with controllers of another brand). When connected either via Bluetooth or cable, the touch controls continue to appear on the screen even if you are already playing with the controller. 

This error also occurs when the option to control the hotbar with the touch function is activated. This didn't happen before, it's awkward to see the touch buttons when you're playing with a controller connected.
