Is anyone having an issue with the Razr M sound cutting out? I had this happen three weeks after getting my phone. Cant hear callers but they can hear me, wont play music or anything. Did a Factory reset on the phone and fixed it for a couple days but started again. I took it to the local Verizon store and they exchanged it for free. Now having my second Razr M in less than a month it is doing it again. I am very frustrated. I dont think its anything I downloaded as anything I have put on the phone I had on my Droid 2 with no problems. Also when the sound goes out the battery drains very fast. Any help would be helpful.
