Microphone not working properly during call (LG G2) I have an LG G2 (d802) with a rooted Lollipop rom installed. During any call the person I'm speaking with has difficulties hearing my voice due to stuttering and distorted sound. Sometimes they stop hearing me altogether and I found out that if I mute and unmute the microphone it starts working again for a very brief period of time. Before dispatching it to the repair shop, is there anything I can do to try and fix the problem? To rule out any (possible?) software bugs. Thanks
Give Microphone Guard app a try.  

My Mobile was working only on Loud-speaker (software issue) and it helped me.
