Hi Everyone, I dropped my ZTE Z820 (Obsidian) on the floor face down. It now has a frozen white screen. I already attempted the hard reset that was recommended but it just flashes the white screen and then back to off. It, obviously, powers up, it rings, produces notification noises. I am extremely desperate, there is no possible way to afford a new phone! (My daughter and I just moved and absolutely need it!) Thank you so much!
