A screen protector is a sheet of clear plastic you adhere to your smartphone’s screen. The plastic is cut to fit the exact shape of your device along with holes for buttons and the speaker — that’s why you buy different screen protectors for different devices.
To apply a screen protector, you generallyclean your device’s screen with a microfiber cloth, apply a bit of soapy water to the screen protector, and then press it on top of the screen. You need to position the protector properly so it fits, and you also need to ensure the screen protector is applied flat on the screen. You wouldn’t want any unsightly bubbles or cracks appearing under the protector.
You end up with a plastic shield over your device’s screen. If your screen would be scratched, the screen protector will be scratched instead. It’s easier to replace the plastic if it gets scratched than to replace the glass on your device’s screen!
