I had the same problem. What I did is hold the power button until it shows “ slide to power off”. Do it, and wait a minute or two. Then turn it back on. I’m really sorry but from here I don’t remember what I did. Maybe this will get you to a new screen? All I remember is it made a difference. If more help is needed, contact me and tell me what it changed I can help from there. I hope this little information helps.
