Fingerprint sensor not responding: what to do

The “fingerprint sensor not responding” warning usually comes from corrupted saved prints, an unsuitable screen protector or a software bug. If the problem started after a screen replacement or liquid contact, the sensor should be checked.

Cep Market Repair TeamIn Kadıköy since 2006
Key points
  • Delete your saved fingerprints and register them again.
  • On in-display readers, a thick or unsuitable protector can block the sensor.
  • Keep the sensor and your finger clean and dry.
  • Restart the phone and update the software.
  • If it started after a screen replacement, the sensor or screen compatibility should be checked.

01Step-by-step fix

  1. Restart the phone. Temporary software glitches clear.
  2. Re-register fingerprints. In the biometrics / security section of Settings, delete saved prints and add them again.
  3. Clean the sensor. Wipe it with a dry, soft cloth; make sure your finger is not wet or very dry.
  4. Check the protector. On in-display readers, remove the protector and test.
  5. Update the software.
  6. Test the sensor. On Samsung, the Samsung Members diagnostics include a fingerprint test.

Menu names vary by brand and software version.

03Sensor repair

If settings and cleaning do not help, the sensor or its connection should be checked. On phones with in-display readers, the sensor sits under the screen, so compatibility matters in a screen replacement. Choose your model on our Samsung models or Xiaomi models page and ask about the fault.

FAQ

Frequently asked questions

01

Why is my fingerprint sensor not responding?

The most common causes are corrupted saved prints, an unsuitable screen protector, a dirty sensor and software bugs.

02

Can a screen protector affect the fingerprint reader?

On in-display readers, thick or unsuitable protectors can make reading harder.

03

Will a fingerprint repair delete my data?

Data is usually preserved during a repair; still, you need to back up your data before the repair starts (backups are the customer’s responsibility).

04

Does re-registering the fingerprint help?

Often, yes. Delete the old one and register your finger again from different angles; make sure your finger is clean and dry.

Phone works but the screen is black: what to do

If your phone rings or vibrates but the screen is black, the phone is on; the problem is the screen or its connection. Force restart and charge it first. Shine a torch close to the screen in the dark: a faint picture means a backlight fault. If it started after a drop or liquid, the screen is usually replaced.
