I've been using the new controls, specifically the Joystick and Aim Crosshair since it is more convenient and stable for Marketplace Addons. The thing is, whenever I kill the app or exit for a moment and open another app, there are frequent occurrences where the controls would reset to their default positions. 

Sure, I could properly exit the app if I'm planning to exit the app and open another one. But that's just extremely incovenient, especially when worlds with or without addons load longer than usual compared to the PC ver. of the game. (My device is pretty good for a mid range).

I hope that this gets fixed in the near future.
