Introduction to the realme Narzo 60x 5G Fingerprint Sensor Issue
The realme Narzo 60x 5G is a feature-packed smartphone valued for its performance and sleek design, which includes a reliable side-mounted fingerprint sensor. However, many users experience issues where the fingerprint sensor fails to register new prints, becomes sluggish in recognition, or completely stops unlocking the device. This problem can stem from minor software glitches, accumulated cache corruption, physical dirt on the sensor surface, or internal hardware damage like a loose flex cable. In this comprehensive diagnostic and repair guide, we will walk you through step-by-step troubleshooting methods to fix your realme Narzo 60x 5G fingerprint sensor issue, whether you are a standard user or a professional mobile technician.
Step-by-Step Software Fixes
Before opening up the phone for hardware repairs, always rule out software-related glitches that frequently interfere with biometric authentication sensors.
1. Clean the Sensor and Your Finger
Fingerprint scanners rely heavily on optical or capacitive clarity. Dust, grease, sweat, or a micro-scratch on the side-mounted power button/sensor can block recognition. Clean the sensor gently using a microfiber cloth and rubbing alcohol, and ensure your finger is clean and dry before testing.
2. Delete and Re-add Fingerprints
Corrupted biometric data can cause recognition failures. Go to Settings > Passwords & Security > Fingerprint, delete all existing registered fingerprints, restart your device, and register your prints again from different angles.
3. Clear System Cache Partition
Temporary system bugs can cause hardware components to malfunction. Boot your realme Narzo 60x 5G into Recovery Mode and clear the system cache partition to refresh background operations without losing personal data.
4. Reset All Settings
If the software configuration has been corrupted by a recent update or app conflict, resetting your system settings can resolve it. Navigate to Settings > System Settings > Backup & Reset > Reset Phone > Reset All Settings.
5. Boot into Safe Mode
Third-party applications—especially screen lockers or security apps—can conflict with the biometric sensor API. Hold the power button, tap and hold "Power Off," and select "Reboot to Safe Mode." If the fingerprint sensor works normally in Safe Mode, uninstall recently downloaded apps.
Hardware Checks & Repair Advice
If software troubleshooting does not resolve the problem, the issue is likely hardware-related. For technicians and advanced DIYers, follow these hardware inspection and repair guidelines:
1. Inspect the Fingerprint Flex Cable
Drops, impacts, or previous improper repairs can dislodge the fingerprint sensor's flexible ribbon cable from the motherboard connector. Carefully power down the device, remove the back cover, and inspect the connection. Reseat the flex cable securely if it is loose.
2. Check for Liquid Damage and Corrosion
Moisture ingress around the side-mounted power button can cause oxidation on the contact pins of the fingerprint module. Clean any visible corrosion using isopropyl alcohol and a soft-bristled brush.
3. Fingerprint Sensor Replacement Guidelines
If the sensor hardware is permanently damaged or cracked:
- Source a genuine or high-quality OEM replacement fingerprint module for the realme Narzo 60x 5G.
- Heat the back cover evenly using a heat gun or repair separation plate to safely remove it.
- Disconnect the battery before handling any connectors to prevent short circuits.
- Install the new sensor module, secure the bracket shield, and reapply fresh adhesive to seal the back cover securely.
Safety Precautions
Always prioritize safety when performing hardware repairs on modern smartphones:
- Power off the device completely before starting any disassembly.
- Always disconnect the battery connector first to prevent motherboard short-circuits.
- Wear anti-static wrist straps to protect sensitive CMOS components from electrostatic discharge (ESD).
- Use appropriate eye protection and heat-resistant gloves when working with a heat gun.

Frequently Asked Questions
1. Why is my realme Narzo 60x 5G fingerprint option missing from settings?
If the fingerprint option has completely disappeared from your settings menu, it usually indicates that the hardware is not being detected by the motherboard. This is commonly caused by a disconnected flex cable after a drop or permanent hardware failure of the sensor module.
2. Can I replace the realme Narzo 60x 5G fingerprint sensor myself?
Yes, if you have basic mobile repair tools like a heat gun, precision screwdrivers, and spudgers. However, exercise caution when removing the back cover and handling internal ribbon cables to avoid tearing them.
3. Does a factory reset fix a broken fingerprint sensor?
A factory reset will fix software-related biometric registration failures and driver conflicts. However, it will not fix physical issues such as a broken sensor glass, liquid damage, or a disconnected ribbon cable.
