Anyone having poor signal and dropped calls with their new Pixel? I read that there is a microphone issue (people can't hear me) and a weak signal/dropped call issue with the same "people can't hear me" problem. Has anyone found a solution? I have turned off advanced calling, changed preferred network type from Global to LTE/CDMA, talked to Google pixel tech and did a factory reset. The same issue continues. Thanks in advance for anyone's suggestions
