When I just looked at my phone it was flashing wierdly so i powered down. It boots fine now but has a gray bar on top of the notification bar that has what appears to be tiny hex dump info and changes with red squares on it. Also suddenly it traces my finger movements on the screen. Running verizon gnex with 4.0.4 rooted and unlocked. I did install an app yesterday that was supposed to put back root even after an ota. Uninstalled it but didn't help. Anyone seen this before and know what to do about it. I'm hoping I don't have to wipe and start over!
