LT button not working properly on Android device

• Eat action does not work immediately after pressing LT button, I have to try pressing more than 5 times in order to eat.
• When placing a block with LT button sometimes it places twice.
• I have tried different controllers with the same result.
• I tested the same controllers with other games and calibration tools to check if my button was bad, but they were working properly out of Minecraft.
