It’s been about 4 months since this has been happening. My Zte Prestige a few months ago it was just the screen freezing, and as a solution, I smacked it on my lap to work and it did. But know, my screen is either, black, unresponsive, or is showing weird and distorted colors. I think this whole situation all started when I first opened the back of the phone and put it back. Please help me with how to fix it and what not to do with the phone.
