Hey guys, Just got my s-view cover and Ive had one problem from time to time, When I open the flip cover, it comes to my unlock screen with my background and stuff, but sometimes half of the screen simply doesnt light up, its like turned off / black, When I drag my finger over it, it works and stuff, but it doesnt show anything but the motion defection of my finger works, Ive found a solution to restart and it fixes it, but i wanted to know if this means my phone is broken? thanks
