I have had my phone since Dec. of last year and haven't had any major problems. My alarm volume does go down on its own, but its not that big of a deal to me. I've never used bluetooth but I recently got a new car with Sync and it turns out that my bluetooth doesn't even turn on. It will attempt to turn on but then just got back to "off" after a few seconds. Is there anything I could do to fix it myself? Should I just reset it, or take it back to a store?
