Hello all, I've had my G4 since Thursday 06/04 and I've been experiencing terrible signal problems, both with data and cell, this is with my original Sim card and then with a new Sim card I picked up from AT&T on Sunday. Data signal keeps going to "E" edge, and my cell signal is terrible, after a couple of missed calls, I looked and the cell icon was no bars and the spinning wheel looking for a signal. I put my Sim card back in my Optimus G Pro and it was 3 bars solid and LTE solid. I experimented with this over 2 days making sure to give it a few hours each time and in the same exact location. Tried it at work, and at home, same results. The people at the AT&T store don't have any suggestions or answers. Is anyone getting worst reception with the G4 than your other phone(s)? I really am debating on keeping the phone because I know I'm stuck with it after the 14 days are up.
