Frequently Asked Questions
Why does my fingerprint sensor stop working after I apply a screen protector?
The sensor often fails because the protector is too thick or contains an air gap between the glass and the screen. The ultrasonic waves lose their signal strength when traveling through too much material. You can usually fix this by re-registering your fingerprints after the protector is installed to help the sensor learn the new surface.
Is it better to use tempered glass or plastic film for this phone?
If you prioritize biometric speed, a high-quality film protector is your best bet. While tempered glass offers superior scratch resistance and a premium feel, it frequently interferes with the ultrasonic sensor unless you use a specialized liquid adhesive system.
Do I need to re-scan my fingerprints after installing a protector?
Yes, you should always delete your old prints and register them again once the protector is on. Since the sensor now has to read through an additional layer, the surface details look slightly different to the phone. Registering the prints with the protector in place ensures the best possible recognition rate.
Can I use the S-Pen with these screen protectors?
Most screen protectors on the market are fully compatible with the S-Pen. If you choose a thick glass model, you might notice a slight difference in pressure sensitivity or a hollow tapping sound while writing. Film protectors generally provide a closer experience to the bare glass of the screen.
What is the purpose of the UV light included with some kits?
The UV light is used to cure the liquid adhesive that bonds a glass protector to your screen. This liquid fills in any microscopic gaps to ensure the sensor can read your print without interference. You must hold the light over the sensor area specifically to ensure a strong, clear bond.
