Screen protectors are pieces of thin plastic film that adhere to the screens of your phones, tablet computers, laptops, portable gaming systems and any other small-screened devices. Although they protect the screen from scratches and other damage, the adhesive side can trap lint and hair against the screen, making for distracting eyesores. Just because your screen protector has dirt on it doesn't mean it should be replaced, though -- simply cleaning it fixes the problem.
Peel the screen protector off of your device.
