I have an unrooted Nexus 7 running 4.2 and a lot of the time it is buttery smooth, except at a random time, usually in front of someone else, when I need to do something RIGHT NOW, and then the Nexus 7 turns into a rebellious teenager. Lagging and freezing badly.
The only thing I have not tried is a wipe. I just don't want to lose saved games and data, and I know of no way to back then up without being rooted.
Any advice on backing up saved game data so I can wipe without fear?
Because really, it's this or back to 4.1.

Have you looked at My Backup?
Otherwise root that sucka! It is a piece of cake.
