If your vivo S50 fingerprint scanner suddenly stops recognizing your fingerprint, unlocking your phone becomes frustrating. You may see repeated failed attempts, slow response times, or no reaction at all. In most cases, the issue is related to screen conditions, fingerprint data, or software settings, and you can fix it without visiting a service center.
Why Your vivo S50 Fingerprint Scanner Is Not Recognizing
- Your finger or the screen is dirty or wet.
- The registered fingerprint data is incomplete or outdated.
- A screen protector is interfering with the sensor.
- The fingerprint area is damaged or scratched.
- Temporary software glitches affecting biometric recognition.
Clean Your Finger and Screen
The fingerprint sensor needs a clear and dry surface to scan properly. Even a thin layer of oil, sweat, or dust can block accurate recognition.
Wipe your finger with a dry cloth, and then clean the screen using a microfiber cloth.
Make sure both surfaces are completely dry, and then try unlocking again.
Remove and Re Register Your Fingerprint
Fingerprint data may become less accurate over time, especially if it was registered quickly or under poor conditions. Re registering your fingerprint improves accuracy and responsiveness.
Open Settings, and then tap Security.
Tap Fingerprint, and then select the registered fingerprint to delete it.
Tap Add fingerprint, and then follow the on screen instructions to register it again carefully.
When registering, press your finger at slightly different angles. This helps the sensor recognize more variations of your fingerprint.
Increase Touch Sensitivity
If you are using a screen protector, it may reduce the scanner’s ability to read your fingerprint properly. Increasing touch sensitivity can improve recognition.
Open Settings, and then tap Display and brightness.
Tap More display settings, and then enable Touch sensitivity.
Test the fingerprint scanner again after enabling the feature.
Restart Your Phone
A simple restart refreshes biometric services and clears temporary system errors. It is quick and often solves minor fingerprint issues.
Press and hold the Power button, and then tap Restart.
Wait for the phone to boot up, and then try unlocking with your fingerprint.
Update the Software
Software updates often include improvements for fingerprint accuracy and performance. Running an outdated version may cause recognition delays or failures.
Open Settings, and then tap System update.
Tap Check for updates, and then install any available updates.
Restart your phone after the update finishes.
Reset All Settings
If the fingerprint scanner still does not work properly, resetting system settings may help. This does not delete your personal data but restores default configurations.
Open Settings, and then tap System management.
Tap Backup and reset, and then select Reset all settings.
Confirm the reset, and then register your fingerprint again.
Most fingerprint recognition problems on the vivo S50 are caused by simple issues like moisture, poor registration, or software conflicts. Once you clean the screen, re register your fingerprint properly, and refresh the system, the scanner should respond faster and more accurately.
FAQs
Why does my vivo S50 fingerprint scanner work sometimes but not always?
Inconsistent recognition usually happens when the fingerprint was not fully captured during setup or when the screen is slightly dirty. Re registering the fingerprint usually fixes this.
Does a screen protector affect the fingerprint scanner?
Yes. Thick or low quality screen protectors can reduce sensitivity. Enabling touch sensitivity or using a compatible protector improves performance.
Can a damaged screen cause fingerprint failure?
Yes. If the fingerprint area is cracked or heavily scratched, the sensor may not read properly. In such cases, professional repair may be necessary.
