The manual says not to cover the bottom inch where the Google logo is while the phone is in use because it will mess up your call quality.
Android noob question: how are you guys getting the signal strength?
menu-> settings-> about phone -> network-> signal strength is right there second item
Yikes... now I wish I hadn't seen that. I'm lucky to get above -80. I mean, it's been good enough for phone calls most of the time (no worse than any other phone I've owned), but now I think I have a problem.
If he's not going above -80 that may be a bad thing, since -60 is above -80.As you said, closer to 0 the better.
