The fingerprint scanner on your vivo X300 Pro is designed to unlock your phone instantly and securely. But sometimes, it may stop recognizing your fingerprint or fail to respond altogether. This can happen for several reasons, from dirty sensors to software glitches.
If your vivo X300 Pro fails to recognize your fingerprint, try the solutions below to get it working again.
Why Your vivo X300 Pro Fingerprint Scanner Might Not Be Working
- Dirt, oil, or moisture on the screen or your finger.
- Fingerprint data not properly registered.
- Screen protector interfering with touch accuracy.
- Outdated software version.
- Hardware or calibration issues with the scanner.
Clean the Screen and Your Finger.
The fingerprint sensor on the vivo X300 Pro sits under the display, so even a thin layer of dirt or moisture can affect detection. Keeping both the screen and your finger clean ensures accurate readings.
- Turn off your phone, and then wipe the screen with a soft microfiber cloth.
- Wash and dry your finger, and then try unlocking the phone again.
If it still does not respond, move on to the next fix.
Re-register Your Fingerprints.
Over time, small changes in your skin texture or moisture levels can make your saved fingerprints less accurate. Re-registering your fingerprints helps restore recognition accuracy.
- Open Settings, and then tap Security and privacy.
- Tap Fingerprint, and then delete the existing fingerprints before adding them again.
Make sure you record the same finger multiple times at slightly different angles for best results.
Remove Screen Protector or Replace It.
Some third-party protectors can reduce touch sensitivity or interfere with the under-display sensor. Removing it temporarily can help you test if it is causing the issue.
- Remove the screen protector carefully.
- Try scanning your fingerprint again to see if it works.
If the sensor works without the protector, consider replacing it with one designed for under-display fingerprint scanners.
Update the Software.
Fingerprint recognition issues can also come from outdated firmware or bugs. Updating ensures the sensor runs with the latest optimizations.
- Open Settings, and then tap System update.
- Tap Check for updates, and then follow the prompts if a new update is available.
Restart the device after installing updates to refresh system processes.
Calibrate the Fingerprint Sensor.
If the problem persists, recalibrating the sensor may fix the issue. This ensures the hardware and software work in sync for accurate detection.
- Open Settings, and then tap Fingerprint.
- Tap Fingerprint calibration, and then follow the on-screen instructions to complete the process.
Once done, test unlocking your phone again using your registered finger.
Reset All Settings.
If none of the methods above work, there may be a system configuration issue. Resetting all settings restores default options without erasing your personal data.
- Open Settings, and then tap System management.
- Tap Reset, and then tap Reset all settings.
After the reset, register your fingerprints again and check if the scanner works normally.
Fingerprint recognition problems are usually minor and can be fixed quickly. Keeping your device clean, software updated, and fingerprints properly registered will ensure your vivo X300 Pro unlocks smoothly every time.
FAQs
Why does my vivo X300 Pro fingerprint scanner respond slowly?
It may happen due to dirt on the display, thick screen protectors, or system lag. Cleaning the screen and closing background apps usually helps.
Can I use multiple fingerprints for better accuracy?
Yes. Registering more than one finger increases success rate, especially if one finger is wet or dirty.
Will a factory reset fix fingerprint issues?
In rare cases, yes. If all else fails, a factory reset can clear software conflicts, but back up your data before doing it.
