My cosmos 2 phone's screen started fritzing out and just completely went black. I can still call and text but cant see it. This EXACT proble happened to my friend with the same EXACT phone and both times (mine and his) were just out of the blue. I have verizon and can i upgrade early or do i have to get the same phone for another 2 years. (I dont want that). Now (3 days later) it's completely broken!
