I realized lately that the speakers on back aren't working properly. The sound only comes out of the top left corner instead of the whole thing. I'd return the phone and get a new one, but I've had it for more than 30 days. Can I still exchange it, or is there any way to fix it? Also, I am currently on a Sprint Relay plan and was wondering if there was any way that I could add Sprint Pick 3 onto that, so I can use Google Voice to get free calling. Maybe not the right forum to ask this on, but I thought I'd give it a shot.
