For some odd reason, my AT&T Galaxy S5 Active began to give me issues with my earbuds mic.. I have tested the earbuds to make sure they did not break using my other phone (Nexus 5), and all is well with the earbuds/mic.. It has worked fine for the past year, now, its no longer working.. People simply can not hear me... any idea why this is happening? I have tried to restart, and no result.. This just happened about 2 days ago..
