I've been through 3 Google Nexus (gsm) phones in less than 2 months. I just sent back one to Samsung today because it was randomly turning off on me. Every day. Samsung was good to send me a new replacement and that arrived today. Right out of the box there is a problem with the screen in that it gives off a textured, scratched look. Vertical lines as if columns of LEDs are not lit. Looks terrible. Looks like I am looking through a window screen when I look at the phone. Called Google who connected me to Samsung, who left me on hold for 20 minutes. I hung up. I replied to Google and told them I want a refund. This is a joke that I can't seem to get a phone that has no issues. I think Google needs to start demanding higher quality standards from manufacturers of what they brand as pure Google devices. This GNex feels cheap and, from my experiencs, performs poorly. I can't blame Jellybean -- maybe for the random shut downs -- but now I know why this phone is relatively cheap. Get what you pay for.
