What device that you use Jeffrey?
But its still happening to my device, Huawei Honor Y336.
Did you exit your world properly? When you exit there's a message saying that your world is being save.
That's wicked. Is this happened when you use texture packs?
It happened to Huawei Honor Y336 only. Other device works fine. Any other method to fix this? I set all volume to max but it didn't fix the problem.
