Certified technicians dispatched to you — same day.
Your Samsung fingerprint sensor won't recognise your fingerprint, fails repeatedly, or doesn't respond at all. Fingerprint sensor failures lock you into PIN or password entry and compromise the phone's convenience and security. Call 0723763173 and our Nairobi technicians will get it working again.
Why Is the Samsung Fingerprint Sensor Not Working?
- Dirty sensor or finger — oil, moisture, or debris on the sensor surface significantly reduces recognition accuracy; clean the sensor and your fingertip
- Screen protector interference — thick or non-compatible screen protectors block the under-display sensor on newer Samsung models; use a Samsung-approved protector or remove it and test
- Fingerprint not enrolled correctly — re-enrol your fingerprint covering all edge areas of your fingerprint, not just the centre
- Software fault — a One UI update changed sensor sensitivity or calibration; re-enrolment after the update usually resolves it
- Physical sensor damage — a drop or crack that reached the sensor area has damaged the sensor hardware
- Screen replacement aftermath — if the screen was recently replaced with a non-Samsung-compatible display, the under-display optical sensor may not function correctly
Sensor Locations on Samsung Models
Under-display optical sensor — Galaxy S and A mid-to-high-range models; embedded in the screen, sensitive to screen quality Side-mounted sensor (power button) — older and budget Galaxy A/M models; more robust and less affected by screen replacements
Our Fingerprint Sensor Repair
We diagnose whether the fault is software (re-enrolment, firmware) or hardware (sensor or screen replacement). We use Samsung-compatible displays that maintain under-display sensor functionality.
