Long story short the phone is very new. The firmware is very buggy. And the radio is down right schizophrenic.
Everything that is bad can and will be fix. But the radio seems to use very little power finding the signal, but once it gets a lock on the signal, boosts the power to keep it.
I was standing about 30 feet from a tower with 1 bar and then I was 4 miles from a tower with all bars.
It is just the firmware and software is not pounded out. Which is why we bought the first round of the phone. To be testers.
