I just got the OTA 4.3 update and now the touch screen is unresponsive. It won't unlock and i can't power it off to reboot. any suggestions ?
First try holding the Volume down and Power button until you get a buzz that lets you know its rebooting, thats gonna drop you into a Fastboot menu, you should then be able to select recovery mode with the volume buttons, and press the power button to confirm it, at this point you should select the clear cache option, NOT the Data one, that should wipe all cache from the previous version of android and hopefully end the freezing
