How to get rid of white vertical lines in my phone screen?
I recently noticed white vertical lines appearing on my phone screen, and it’s becoming quite frustrating. These lines are affecting my ability to use various apps, read messages, and even watch videos. At first, I thought it was a temporary glitch, but the lines have persisted and seem to be getting worse. I am concerned that this could be a hardware issue or something more serious. I’ve tried restarting my phone and even performed a factory reset, but nothing seems to work. Can anyone provide guidance on what might be causing these lines and how to properly address this issue?

From my experience, one possible fix is cleaning and reseating the display connectors. First, power off your phone and carefully open the back cover with a plastic pry tool. Disconnect the battery and display connectors with a non-metallic tool. Clean the connectors using isopropyl alcohol and a soft brush. Then, reconnect the cables and close the back cover. Turn on your phone to check if the issue is resolved.
