Armor film and Face ID – does it affect recognition?

Face ID is one of the most important features of the iPhone, and many users are wondering: will a screen protector interfere with facial recognition? This question has become even more relevant in the 2025-2026 models, as the sensors at the top of the screen are more accurate than ever.

Does the screen protector affect Face ID recognition?

Short answer: A high-quality screen protector will NOT prevent Face ID from working.

Face ID uses an infrared projector and depth camera, which are not sensitive to thin protective films. Problems almost always occur for the following reasons:

• The film partially covers the sensor area – cheap films are cut incorrectly.
• Dirty or cloudy surface – especially on low-quality bulletproof glasses.
• Cracks or air bubbles – affect the camera's field of view.

High-quality armor films, such as ➡ Hydrogel and Titan covers do not cover the sensor part and are optically transparent even to infrared.

Why do some tempered glass screens reduce the performance of Face ID?

Cheap shelters often have:

• Too thick glass (0.50 mm+) which refracts light.
• Rough oleophobic surface that blurs the sensor.
• Incorrect cut – notch area is not accurate.

If you choose a glass screen protector, we recommend slim premium models:

➡ Armored glass collection (premium thin glass, precise cutting)

Can Face ID recognition be improved with an armor film?

Yes. Here's how:

1. Clean the sensor area with a microfiber cloth.
2. Make sure the film does not cover the notch.
3. Start a new Face ID registration after installing the armor film.

Summary

A good screen protector or thin tempered glass will not weaken Face ID at all.

Problems are almost always caused by a cheap or incorrectly cut screen protector. When you use a high-quality, thin, and properly designed screen protector, Face ID will work normally even in low light.
