The iPhone 13 features a slightly smaller notch and a different sensor layout compared to the iPhone 12, which means the cutouts on screen protectors must be adjusted accordingly. Even a small shift can cause misalignment, resulting in reduced screen protection or interference with facial recognition sensors. Therefore, screen protectors designed for the iPhone 13 include precise cutouts that align with its unique front hardware. Mobile Phone Guard

The materials and protective technologies used in tempered glass or film screen protectors are generally similar between iPhone 12 and iPhone 13 models. Most companies focus on standard features like anti-scratch, oleophobic coatings, and high transparency. However, some newer screen protectors for iPhone 13 may include added benefits like better edge adhesion or compatibility with Face ID sensors, reflecting incremental improvements rather than major shifts.

This is a common myth. Using a screen protector designed for the iPhone 12 on an iPhone 13 likely won't break Face ID, but because of misaligned cutouts, it could interfere with the TrueDepth camera’s sensors and reduce Face ID’s effectiveness. To keep Face ID working smoothly, make sure to choose a screen protector specifically tailored for the iPhone 13’s front sensor layout. Mobile Phone Guard
