4.2.2 has been nothing but trouble for me and my tab 2 10.1 16gb w/WiFi
Ever since the upgrade it's been a real hassle to get screenshots. The features are the same, nothing's improved. It's gotten slow as hell. Pressing the 2 buttons for a screenshot is causing too much ware & tear on them. Now it can't update the firmware that samsung keeps requesting, with or without kies. And it won't recover. Now today all of a sudden it is continuously rebooting non-stop every few minutes,uuuuuugh!
My solution is to downgrade back to ICS. I hate Jelly Bean. Do they really think they can keep upgrading these machine without eventually upgrading the hardware too? WTH?
