Galaxy Nexus(Global Version) Post 4.2 Issues.

Since I got the OTA for 4.2 my Nexus has been acting very odd.

1. Sometimes when multitasking the phone will simply shut off and will require a battery removal in order to be powered back up.

2. When my alarm goes off, I swipe to the right and the screen simply dies. Alerts keep chiming, secondary alarms will go off, notification light will still blink but the screen will not power back on.

3. Volume is very unreliable now. Sometimes the phone will ring, sometimes it will just vibrate. Sometimes the screen will just light up with a call but no vibrate or ring.

I'm not entirely sure what's going on, but I have never, EVER had an issue with this phone before 4.2

Is anyone else experiencing oddities?
