Help!!, I bought a used samsung continuum, and it worked fine for a week and half maybe. But now it glitching. every 25 secs maybe less the screen blacks out like it freezing than it goes back to the lock screen. i dont know what going on with it but its driving me crazy. i cant even get a text message in before it blacks out and goes to lock screen. sidenote i did download a app from the app store and maybe 10 mins after it started doing it, could it be that?? do i need a new battery. someone please help me before i throw it out the window!!
