RT And LT Are Not Working

I am using Xiaomi Mi 6. I connect my DS4 to my phone via bluetooth. Keybinds of DS4 are wrong in Android but you can fix it with a keylayout file. Every button except RT and LT are working. Those 2 buttons work in every game except Minecraft. I can also see they are working in key mapper program. The game just doesn't detect those 2 button. I can't also use them to map other actions in Mc. This error is only my Android device, working fine on Windows 10 Edition.
