new member, 1st thread/post... as title says. i can use phone and all goes well, then sometimes ill go to use the phone, slide to unlock, and everything missing, only background appears... if i turn the phone off, and turn it on again it works fine. but then could possibly do it again. also problem number two... when in a txt, or in my browser, the screen will freeze and not let me do anything but then the screen starts scrolling up and down and acting up and none of the front home buttons will work at that time, i have to hit the top lock/power button to then hopefully go back to what i was doing. thank you very much for your help!
