I have come across a serious crash issue with Minecraft Pocket Edition's new update/s (0.6.0/0.6.1).
I believe this is an issue with performance, although my phone actually mostly performs better than Minecraft: Pocket Edition on my tablet, on which the game never crashes.
When I load up large worlds (E.g. Isak_01, a city world, structures take up about 90% of the world), whether I am on Fancy Graphics or Low Graphics Quality, after playing in the world for a few seconds (with a VERY low framerate), my phone freezes. The phone does not respond again unless I take out the battery and put it back in again.
NOTE: This is a common crash. Only reproduce-able in large worlds.
Please respond, someone, and please fix this problem for the next update.
