Setting up your fingerprint scanner to work reliably with a screen protector requires a few simple steps to help the sensor adapt to the added layer on your screen.
The most crucial step after installing a screen protector is to re-register your fingerprint. Screen protectors, especially thicker ones, can slightly alter the way your fingerprint interacts with the sensor, whether it's an in-display optical, ultrasonic, or capacitive sensor.
Steps to Optimize Fingerprint Recognition with a Screen Protector
Follow these steps to ensure your fingerprint works smoothly after adding a screen protector:
-
Re-register Your Fingerprint(s):
- Immediately after installing your screen protector, navigate to your phone's Settings.
- Find the Security & Privacy or Biometrics & Password section.
- Locate the Fingerprint settings.
- You will likely need to enter your PIN, pattern, or password.
- Delete any existing registered fingerprints.
- Select the option to Add Fingerprint or Register Fingerprint.
- Follow the on-screen prompts to scan your finger. Make sure to cover the entire sensor area and move your finger slightly as instructed.
- Why this helps: As mentioned in the reference, registering your fingerprint after the screen protector is installed helps the sensor adapt to the added layer.
-
Enable Touch Sensitivity (If Available):
- Some smartphones have a setting specifically designed to improve touch response when using screen protectors.
- Go to your phone's Settings.
- Look for Display or Advanced Features settings.
- Find an option like Touch Sensitivity, Glove Mode, or Screen Protector Mode.
- Toggle this setting on.
- Why this helps: Many phones offer a setting to increase touch sensitivity when using screen protectors, making it easier for the sensor (and the screen overall) to detect your touch and fingerprint through the protector.
By following these steps, particularly re-registering your fingerprints after installation, you significantly improve the likelihood of your fingerprint sensor working accurately and consistently with your screen protector.
