4 Screen Protectors Can Ward off Fingerprints

In addition to being fairly scratch-resistant, most modern smartphones (including iPhones) typically have a thin oleophobic layer. Simply put, this coating helps ward off smudges, fingerprints and marks left by the natural oils from fingers, hands and cheeks.

But oleophobic layers aren’t indefinite, the thin coating can degrade with use and wear off. While an oleophobic layer’s lifespan is dependent on a number of factors, you will eventually find that your screen does accumulate fingerprints and smudges. A good screen protector can increase its lifespan or offer its own anti-smudging abilities.
