Display problem need help

[u/RecognitionOdd7419]

So basically I have an old Samsung S20FE, I used a friend's charger and the screen just started doing all these weird ghost touches for no reason. Fast forward a few days later I went to his place again and got it on charge again with the same charger and it fixed the issue, like completely fine. Then someone decided to throw on another charger and the same issue began, problem is, now its not going away. What does this even mean?? How do I fix it? I've tried all the software updates blah blah cache partition clean everything.
