Galaxy S7 Edge phone.

This is a duplicate of MCPE-14363 and MCPE-13494 (and others linked), but I couldn't see how to re open it. So starting a new one for version 1. Just received a Xiaomi Mi Bluetooth Wireless Gamepad and it works brilliantly with MCPE, other than the R2 button. I assume it's meant to be "Trigger2" as a MCPE button. All other buttons, and sticks work, and the button works fine in other games, and the Bluetooh testing apps on Android.

It's sooo close to being lovely, and wanted to buy the Gear VR edition to use this with, but this button is kind of essential (well not, but it does take away from a very natural button to use to place/attack/destroy).

Thanks

Update: Still affects new 1.0.2 on Android. Really frustrating as it's such a useful button for attack when moving (using the front right button instead of trigger for the moment, but then can only scroll through to the left!)
