Mine has been acting crazy the last couple of days as well. Maybe they are all losing their minds at the same time. I've had mine reboot randomly several times, the audio has stopped working in the middle of several phone calls and while playing music in both Pandora and Google Music and yesterday while driving home I had it in my mount and the screen cut itself in half for about 10 minutes. Top of the screen was normal, bottom was black. When that happened I took it out of the mount and held it in portrait rather than landscape and the screen never rotated.
Maybe they are all excited about an update from Big Red and a hidden ADD function is causing them to be all spastic. I dunno....but it is a little entertaining to anticipate what weird thing will happen next.
