How is the game's performance looking on Android?

How is this game's performance looking? Is an A.R game and it's running on Galaxy Y. I can't see nothing wrong, but the problem is that sometimes, when I lost the tracking (and execute some codes to take off all renderers and some behaviours) the game just stop responding at all. These lines show the problem with 'Watchdog wakeup'.

Seems like it starts happening after UpdateTrackablePoses function gets called. How is the performance looking? Someone already has knowledge about QUALCOMM A.R package and know how to get through this problem?

Thanks from now!
