The tempered glass of Tech-Protect is a hardened glass, specially made to cover and protect the screen of your mobile phone from scratches and other damages. It does not affect the functionality of the screen. In case of a drop, it does not guarantee that the screen will not break along with it, however, it provides an additional protection. The matte coating prevents the formation of fingerprints on its surface, as well as the reflection of light. In some cases, it may limit the clarity of the screen. It is compatible with iPhone 15 Plus.
