Screen has fading vertical lines
My iphone 6s fell screen down about a week ago, now the screen has fading vertical lines and an unresponsive screen sometimes, and sometimes it works. If I shut off the screen the lines are cleared away but come back. When the screen is responsive, if I lock the phone and open it back up, it is unresponsive again. I've tried restarting, force restarting, there are no more updates for the phone due to its age. Looking for a possible fix for this issue
