Phone: iPhone SE iOS: Latest, 10.1.1 Tried, but no luck. 1. Restored the phone as brand new. 2. Tried with a different headsett. 3. The phone is 2-3 weeks old and it's brand new, never dropped. Issue: When I call or answering the phone with my Apple headsett sometime the people can't hear me and sometime I can't hear them. But if I activate the speaker fast and then de-activating it again I can hear people in my headsett and they can hear me. This issue starts sometimes, and the only way for me to get ridd of it is to un-plug the headsett for some time (minutes) then plug it in again and then it works as it should during a period of time but the issue always starts again. It also works to reboot the phone sometimes. This issue are only with the headsett pluged in if I make a reguler call without the headsett I have no issue. So does someone know how to solve this issue? I guess that it's a software issue as I can "make it work" again when I activate the speaker and then de-activate it during the call and then everything works as it should. But what do you think? Is it a bugg or is it HW issue?
