I just replace the screen on this iPhone 6 and there’s little squares on the top of the screen. I cleaned the flex cable and connectors with alcohol and made sure its on good. They seem to fade away as the screen stays on for awhile… anyone know how to get rid of them or know what causes it?

Have you tested a new screen or tried applying pressure to it while device is on? I remember getting this on the 5 &5c and it was due to the flex cable being damaged.
