Hello all, I have had a Gnex since launch and love it. I bought the best buy replacement plan with it and was considering using it. Reason being, all the time, people I talk to hear themselves. Friends, girlfriend, parents, the only common deliminator is me. Yesterday I was calling a stranger to ask about a rental house and I heard him say, "man I can hear myself echo. I hate my phone," but I knew it was me causing the problem. Should I exchange my device? I have tried different ROMS one different versions of android, different radios, and different volumes on my end but nothing changes and I cant figure out what triggers it.
