I am getting some of those problems with my v950 along with when opening the camera, I sometime get freezing and have to take the battery out to reset the phone and when I put the battery back in and turn the phone on, I get the color noise on the internal screen and I turn it off and back on and still get the color noise in there.
I got a replacement coming in tomorrow afternoon so hopefully that will solve the problem but otherwise the phone is been good to me overall all with watching NASCAR.
