For all the newcomers - the problem was that 4.0 did not tell the hardware memory controller to trim on deletes.
When memory filled up, lag got horrible.

The real miracle was that 4.1.2 fixed that; memory is now released correctly.

ForeverGone gets an assist, in that it fills your storage with dummy data, then deletes it.
This lets the memory controller truncate correctly..
This is really a security program, but it is very handy in cleaning up the memory.

You lost me there - Currents is not an app you install. It just comes with Android, along with a few other Google apps.

ForeverGone gets a huge assist. Saved my nexus from a wall.

After installing 4.2 (or any major update), always do a Factory Reset. Then disable your currents sync, and run Forever Gone.

If that doesn't help your lag, your placebo is broken

Seriously worked for me though

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.

Ok why didn't any of you nice people tell me about 'safe mode'? Huh? Huh!?

Hold power button to get power off prompt then press and hold the power off/shutdown button.. Reboots into safe mode.... Tried it just now and its snap city! It disables 3rd party apps.
Many apps will still work some not, but if you can feel the difference then you know its a 3rd party app or widget messing with your program. I have currents disabled btw.

Apparently on reboot all is restored, so its a win win test of your system. I can definitely feel less lag as it was making my normally calm self angry. So now I hunt the app or apps slowing things down.

Suck it and see.
