Hi, I'm using a Redmi note 4.
The problem arose when I signed up for the beta testing of Minecraft.
I installed a texture pack (feathercloud deluxe) from a .mcpack file.
After installing I closed the game (version 1.6.0.5) and some time later, I came back, created a new world in creative mode. I just had fun. Testing out one hit kills to different monsters. I could easily open the inventory and teleported using ender pearls. I found an underwater ruin and when I tried to open a chest in it. The game crashed repeatedly. It tried it many times with the same results.

Now before I became a beta tester, on version 1.4.4, I had the same problems with the extension of the inventory button. I tried some texture packs.(jolicraft, mad pixels.) When coming back to the game, if I pressed the inventory button, the game crashed. Consistently. Or if instead I tried opening a chest, the game crashed as well. No exception.

It only happened when I installed a texture pack and after playing, left the game and came back.
Sometimes, the textures were reset, without any messages.
