When i try to open my minecraft on my phone, it will load to the main menu of minecraft. I then click play and it takes me to where i can choose my world, but then when I look my world isn't there. So I switch it back and forth from external storage to application storage and back again. Then my world shows up and i click on it to play it. But when I goes to the loading sign of minecraft, it loads for a few seconds and then it completely kicks me out of mincraft and back to the home screen of my phone.
