For other gnex owners, do you get good cell service? Mine is terrible, both wifi and network seem to be much worse than previous phones (droid x, htc incredible, razr maxx). It's very slow, seems like it is always maxxed out on memory, battery is useless, even the mammoth extended 3500 or 3800 mah. Texting is a disaster. Group texts are the bain of my existence. But that is partly an android issue, just seems to be worse with this phone than the razr maxx.
