i found an issue. guys please help to see if its happening on your side too.
go to Messaging. Read your SMS. Press the soft back key.
Notice that you cannot return to Home screen. Only way is center button.
However, if you just go into Messaging WITHOUT reading any sms,
you can exit with the soft back key.
If you do a screen off(locked) and on(unlocked), the back key will work to exit.
full wipe. clean install. (i know its no wipe but i prefer to wipe every time)
