Hi. I'm having the issues with MPE on my Nexus S running Android 4.1.1 "Jelly Bean" since 0.3.3 version. Game and phone works fine, but after I move a little around the map (and just in-game, not in the menu), the phone freezes completely and just battery pull resolves the problem. It works the same every time I run Minecraft PE it turns the same. I hoped 0.4.0 fix the issue but it didn't. For now the game is unplayable for me and (I assume) the rest of people using Android 4.1.
