I ended up taking my phone to Sprint because it started turning on and off by itself. When I plugged in to charge it just shut off. So they told me that they would be giving me a replacement phone because they couldn't fix the issue. Which I figured is probably a refurbished phone. Has anyone had to turn in their phone because of this and if so, did you have any issues with the replacement phone? I liked my phone and am a little skittish about a refurb phones, because i have heard some people complain about them. Thanks.
