I recently replaced my screen and made sure all the cables were plugged in. iPod works normally for like 5 minutes but then starts glitching out by scrolling up and down and zooming in and out even when I’m not touching it. Any ideas?
That is ghost touching and that means the replacement screen is bad.
You can’t. Apple only has the calibration machines released to service centers for iPhone, any iPod Touch or iPad repair and calibration is done in factory.
