ipaniwala, Jul 22, 2015 : I have strange issue with my One Plus one. The mic on my headset stops working and no one can hear me during a phone call. I have tried 2 different headsets and it does the same thing. The headset works fine on my other phone. Its like it goes into some sort of mute mode. Issue first started after my updated my One Plus one to Exodus Rom. I am on T-mobile. Did not have this issue on CM 12.
