I've had this phone since November and it's still in great condition. From the start though call quality hasn't been amazing, friends often tell me that I'm very quite (I'm not actually speaking quietly). In the last few days though absolutely no one can hear me unless I have my headphones plugged in but even then it's not ALL the time that it works. The headphones don't have a mic so it's nothing to do with them I imagine. I've made a few videos to check that it was still recording sound and it works perfectly still. It's really left me baffled. While the phone is still in warranty I really do want to avoid sending it to LG as I don't have a backup phone.
Does anyone have any idea what could be causing this? I'm running stock vanilla 6.0.1 I don't have a case on the phone (I've seen a few people complain their case covers up their mic), neither I've muted the call (I've tapped the mute button a few times to make sure).
