I know a lot of people share the same issue as me and i don't think it has ever been fixed or they have any desire to fix it. When i'm using my headset my mic suddenly goes mute i have to either unplug it and re plug it in. Or turn on and off the speaker but its a hassle. This is the same issue i had with my zte axon 7 which was frustrating. I'm extremely disappointed because its a great phone. Not sure if anyone has a solution to this or is having the same issue. I returned my pixel xl for this phone and its great but as person who is constantly using the headset its such a pain to deal with it.
