The bug

Observed Results

When connecting an Xbox controller to an Android mobile device to play Minecraft with it, when the RT or LT buttons on the controller are pressed, it causes the in-game camera to spin around uncontrollably even when no buttons are being pressed on the controller. In fact, the LT and RT buttons do not do their assigned function at all when pressed. Even when disconnecting the controller from the device and using touch controls, the camera still spins uncontrollably. The only way to fix this issue is to restart Minecraft entirely. I also tried using this controller on the Windows 10 edition of Minecraft and the LT and RT buttons work without any issues. I also tried an old Logitech F310 controller on both the mobile and Windows 10 versions of Minecraft and strangely, it works with no issues on both versions.

The mobile device I used was a Samsung Galaxy S9+ running Android 10. The controller I used was a third-party Xbox controller connected to the mobile device using Samsungs USB-A to USB-C adapter.

Expected Results

For the RT and LT buttons on the Xbox controller to do their assigned function on the Android version of the game (attack/destroy and use item/place block respectively) and not cause the camera to spin uncontrollably.

How To Reproduce

1. Connect an Xbox controller to the charge port of the mobile device (usually by using a USB-A to USB-C or USB-A to Micro-USB adapter).
2. Open Minecraft and enter into a world
3. Press either the RT or the LT buttons on the controller and the bug should occur.
