First off, love my Nexus. Going to try and swap it for a new one as my current Galaxy Nexus is exhibiting some odd and frustrating behavior. Since I bought it, I've felt like the 4G signal it received was fairly weak, especially compared to friend's and family's 4G phones which were at least "showing" better reception in the same spot.
For the past few months, my signal at work and home both drop off fairly frequently throughout the day (couple times per hour). It's acting like it's bouncing from one tower to another, but it only seems to drop signal when I'm actually trying to do something. It will show 2 bars, but as soon as I try and load a webpage, or send a text, I get whatever failed message pertains to the particular application (text not sent, webpage cannot load, etc) and the bars disappear. About 30 seconds later they come back to the same signal strength. Now I'll admit that at work, many people don't get great reception on any service (I'm in downtown Portland). At home, I usually get 2-3 bars, and still the signal will bounce/drop/disappear.
For the past few weeks, the signal will sometimes completely vanish, and won't return until I restart the phone.
In the past few days, the phone has, on three occasions I know about, shut down and restarted itself. I was hoping it was self-updating (and perhaps fixing these issues), but alas the reception problem still exists. Just 5 minutes ago I had to restart, as I lost all signal, and it stayed that way for 10 minutes until I restarted. When it came back on I had 3 bars, and currently have 2 sitting at my desk.
I'm not rooted and on Version 4.0.2. I bought this phone at Costco about six months ago.
Thanks all for listening to my gripes. Hopefully a new Nexus will fix this, as I really do love the phone, aside from these annoying issues.
