Phone is 3 years old. It finally locked up at the pattern code and would take calls but crash immediately when pattern was entered. System UI interface error. Reboots were tried. Apps all updated. Had 30 free gigs of memory. Once 8.0 hit it destroyed my phone. I had to factory reset 2 hours ago. And well. The system ui error is back. This update is a nightmare.
