Good luck with lag, I had similar probs after ota but kept shucking un-needed apps and moved all I could to sd via manage and finally got my snap back. Oh ya, after ota Helix is out. I tried pro but finally went with ADW and luv it, you really need a theme for it to work good.
Best and gl..
Come on flash
Oh btw, why do ppl use tapatalk?
I use xScope and all seems fine.
