I've had the flip 6 for around 6 months. I've hunted online and can't really find anything on this issue so I'm curious if anyone else is experiencing similar. When on a call I can hear the other person perfect which is great however I've had alot of people ask if I'm still there etc as they can't hear me (they can at the start of the call this happens during) I've already contacted my network provider and had a replacement SIM sent. This also happens on WiFi calling. One thing I have noticed it seems to only happen when on calls to landline numbers. I don't recall having this issue on call to a mobile number. The mic works fine as I've tested it and have no issues with mobile numbers and also face the same issues with landlines when on a call in the car via android auto. Has anyone had similar issues or heard of anything like this?
