Re: Game randomly freezes up during arena battles
No antivirus, but often have apps like Gmail, Reddit, Twitter, Facebook etc running in the background. It shouldn't really matter though, since they're usually running as background tasks in Android anyway doing synchronizing etc as usual.
Given the randomness these freeze-ups happens, there's really not more info I can provide, besides that they usually happens between 20-30 seconds into battle, and often during/after the more graphic "intensive" animations (AoE attacks, multiple GUI/status updates and so on like Trayas saber storm, etc).
