hi all, i have a moto g7, have been using it for ~6 months now. recently, every single person i talk to on the phone complains about hearing their own voice as an echo about a half second after they say it. there is no echo on my side. i switched phones with my wife to see for myself, and sure enough, every single thing that is said is echoed exactly back into their ear piece. looking further, it ONLY happens during regular phone talking. it does not echo during bluetooth calls, it does not echo with a plugged in headset/earphones, it does not echo when on speakerphone. it only echoes during normal phone calls directly through the phone while not on speakerphone. for grins, i also tried to make phone calls through wi-fi apps like facebook messenger/what's app. there is no echo through those apps. it ONLY echoes during normal phone calls through my network (AT&T). my wife has the exact same phone that we got on the exact same day, and only i get the problem (it's not a signal or network problem since she has no problems from the same house/tower/age and model of phone). i have also tried it on different towers (my job is ~20 miles away from the house), and have the same problem.
i have already removed the protective case, re-started the phone multiple times, tried it in SAFE MODE, removed/reset the SIM card, and even did a full factory reset without re-installing any apps. i still have the problem. i was assuming it was a hardware issue, but then i would think that it should have the same problem when talking on wi-fi apps...but it doesn't. i am completely out of further ideas. please help!
