Phone - Doogee X5
When placing 256 or more cauldrons in a world (I was making pictures with dyed water), the game hides the GUI. When placing or destroying a block, the screen flashes blue.
When quitting the game after this, the screen turns green and goes to the Android home screen.
I had to delete a world I had worked on for a long time!
