With a screen protector, you protect the screen of your smartphone. Place a screen protector over your touchscreen and your screen will remain free from scratches. Feel free to put your device in your pocket along with your keys. You can choose a glass or plastic screen protector. A glass screen protector feels like your own screen and offers protection against scratches. Plastic offers less protection, but the protective film is thinner and less noticeable. Go for a protective glass with a blue light filter if you suffer from tired eyes. A screen protector with privacy filter ensures that nobody can peek at your screen. Do you have a phone case? A case-friendly screen protector doesn't extend to the edges, so that your case still fits well around your device.
