Updated to kitkat 4.4.2 and now, when I reboot, this is what comes up on the screen. I can't escape, exit or return to the home launcher. Some tabs work on the test screen but exit, full test... do not. I can only power off but it just rebbots to this screen. I even did a factory restore, erasing everything, but no luck. This appears to be the factory testing sequence that is supposed to be disabled or removed? before leaving the assembly line I would presume? Any help or ideas? George
