I got mine a week ago. Have been having freezing issues when I was in the browser, and other various apps. Phone would lock up, with the power button being the only functional thing, and then the app will force close or w.e it says. I was about to return the thing but I do not want to play that game yet because I am worried I could get another phone with a different issue.
But anyways I did a factory reset and got a new SD card. Slowly started putting some core apps that I need back on. Its only been a day, but no freezing, Gonna go another few days to see if it happens again and if I need to swap it out.
