Phone "Fingerprint" Sensor is Too Slow
4.5
It takes several seconds or multiple tries for the fingerprint sensor to recognize your finger.
Symptoms
- Delayed unlock
- Multiple attempts
- Failed recognition
Possible Causes
- Dry skin
- Dirty sensor
- Thick screen protector
Step-by-Step Fix
1
Re-register Fingerprints
Delete your old prints and register them again, pressing firmly.
2
Register the Same Finger Twice
Adds more data points for the same finger, increasing speed and accuracy.
3
Moisturize Your Hands
Extremely dry skin doesn't have clear ridges for the sensor to read.
When to See a Technician
Optical sensors (under-screen) are slower than physical ones; keeping the screen clean is vital for speed.
