Haven't seen a thread started on this, so here goes.
1) Stock camera app doesn't work. Makes screen flicker green! Have to open something else to make it go away. Other camera apps work fine.
2) Not so much a bug, but annoyance. Cannot drag GoSMS app to new bottom app bar. Other apps move fine.
3) This one might be a biggie. Screen has a huge delay coming on. When I hit power button, bottom buttons light up but screen stays off. I then power "off" and power back on and wait about 10 seconds before screen appears. Might need a reset, but hopefully not a factory reset!
I think that is it for now...
Not seeing these specifics, but the update did get stuck in an endless cycle of reboots that required pulling the battery to break. Panning the camera causes the image on the screen to jerk (there is a slight green hue -- but very slight). Don't see the screen delay mentioned, but do so an occasional slight lag (no other word for it).
My biggest complaint with ICS is that battery life, far from getting better as expected, is about half what it was with Gingerbread. According to Verizon, ICS does impact battery life -- though say what I get is more severe that expected.
All in all this reminds me of the Thunderbolt update that caused constant reboots followed by the "fix" that sent SMS to random people.
