So, Friday...told a co-worker -- who is 100% stock he could pull the OTA. He did, and then when it booted back up -- his home screens would appear for a moment, then go black from the notification bar down. Completely unresponsive. He did a few battery pulls and let it sit for a few hours. He ended up going to VZW store -- they did some sort of reset. He wasn't very clear on what exactly they did, but it didn't sound like a factory reset or even a data wipe. But now, the lower 2/3's of his screen flickers a lot. there's a perpetual line where it starts...anyone else having this issue? Just trying to find him some answers since I told him to go ahead and update.
