Was great then rooted and the problems started coming. On stock root using Nova launcher then came the process.media.whatever error popping up randomly then the infrequent random rebooting then the problem with calling. I start a call and it can be 10/15min in, doesn't matter, and the other person is unable to hear me. This is a known problem with the GNex with lots of mythical fixes like downloading new radios, rooting, getting 4.0.3
Still the best phone I've owned. I will just be patient for fixes.
