Samsung Galaxy J7
Weird and ANNOYING bug.
Try to reproduce the bug:
Get a tamed horse. Then ride on it, I'm not sure whether with amor or not will change anything. Then while mounted on the horse, try multitasking and switch to a different app then go back to Minecraft PE and face the black screen of death. Annoying crash, MCPE won't load again and I have to force close it and back on my world, I lose all my previous work and start over again. :'( Sorry for typos or other errors. Also help, I can't attach pictures on this post, I'll post one when I can.
