Hello, all! I have an HTC HD7 from AT&T. I have recently been having problems with trying to get the volume to go down, but to no avail. It has been stuck at 30 since yesterday, and I'm not exactly sure why. I'm running Mango on my phone, and haven't had this problem until now. As far as damage goes, there's been the basic stuff- dropping it on the floor, almost stepping on it...and dropping it in the toilet. It fortunately worked after the incident thanks to the rice trick, and haven't had this problem until a long time after that. Any advice on what I can do to get the volume button working?
