I took my phone into the Samsung store where they have professionals there to do all the checks and fix your phone. I took it in and they told me that they were going to do a full check up and fix everything and to come back in a couple of hours. When I went back they said everything was fixed and the phone was fine now. When I got it home the mic was still not working and all I had done was get my phone wiped clean. Useless. All that messing around by so called professionals and all I got was a phone that was still faulty and I got all my stuff wiped off my phone for nothing. Some professionals! Really disappointed with Samsung.
