Xbox 1 S Controller not working

I have paired my Xbox one controller to my tablet via Bluetooth, and it works with my device. Whenever I open Minecraft, the game seems to not recognize that the controller is connected. The game receives no input from the controller, except for the D-pad (including left stick) and the left menu button. D-pad (left stick) moves the player, menu button pauses the game. No other buttons work, and trying to keybind doesn't either. When using the left stick or d-pad, it shows on-screen as though I am phisically touching the buttons (which to metion, aren't supposed to be there if I'm not mistaken.)
