Minecraft Pocket Edition - Crash after 30 seconds in any World

10 to 30 seconds into gameplay on any World, Minecraft Pocket Edition suddenly goes black and back to device home screen. The bug needs to be fixed, as this is ruining the game and experience for many players. No "Minecraft Pocket Edition has stopped" error is displayed on device screen.

In addition, Global Resources almost always make the game crash. Another bug that needs to be fixed.
