hi i just bought my esteem today at an authorized dealer and so far so good. then i was setting my wallpaper and the phone went black, then i heard the metro pcs wireless for all but the screen was still black. so i took the battery off and turned it back on and it takes a while and when the lockscreen comes up its like missing a backround and i cant slide to unlock. nothing responds, not even locking the screen and unlocking. I turned it off again and left the battery out for a bit then tried again and this time the same thing happened but now it says insert metro SIM. Nothing was responding so i took the battery out again. Now its just sitting with the battery off. Maybe since i bought it from an authorized dealer they couldve had a bad batch sitting there for a while ? Maybe it didnt come with the update like theyre supposed to come with now? Help !
