Still torn- the phone itself is a great device, but it makes me sad/mad when I see 1-0 bars in areas where I used to have 2-3 bars. I don't make calls a lot, but when I do, I want it to work.
I'll wouldn't be too discouraged by how many bars you see.
My htc rezound would show full bars but the dBm would read - 95(not a great number).
My S3 shows full bars the vast majority of the time, it gets less at my building at work(which is 50 years old and I'm behind multiple cinderblock walls) but the dBm stills is around - 73.
Short story... Less bars doesn't necessarily mean weaker reception.
