Infinix has made a name for itself by offering affordable yet feature-packed smartphones, appealing to a broad audience worldwide. Models like the Infinix X655, X656, X693, X682, X675, X666, X650, X626, X6716, X6816, X695, and X6711 are popular within the budget smartphone segment. These phones come with various features, including an integrated fingerprint scanner for added security. However, like all technology, these fingerprint sensors can sometimes fail, causing inconvenience. If you’re experiencing issues with the fingerprint sensor, you may need to replace it. This guide will walk you through the process of replacing the fingerprint sensor on your Infinix device, including the steps involved, costs, and considerations before replacing the sensor.
Why Does the Fingerprint Sensor Fail?
Before diving into the replacement process, it’s important to understand why the fingerprint sensor might fail. There are several potential reasons for malfunction:
- Physical Damage: If the phone has been dropped or subjected to water damage, it could lead to issues with the fingerprint sensor.
- Software Glitches: Sometimes, fingerprint sensor issues can stem from software malfunctions. This could be resolved with a system update or a factory reset.
- Dirt or Dust Accumulation: The fingerprint scanner can become obstructed by dirt, grease, or dust, leading to failure. Cleaning it might solve the problem in such cases.
- Aging Hardware: Over time, the fingerprint sensor may degrade in performance, causing it to stop working correctly.
- Manufacturing Defects: In rare instances, the fingerprint sensor might fail due to manufacturing issues, requiring replacement.
How to Check If You Need a Fingerprint Replacement
To determine if your Infinix phone’s fingerprint sensor needs replacement, you can follow these steps:
- Test Fingerprint Recognition: Go to your phone’s “Settings” and open the “Biometrics” or “Security” section. Try adding a new fingerprint or re-enrolling your fingerprint. If the system cannot recognize your finger or struggles to save the print, it’s a sign that the sensor is not working properly.
- Try a Clean: Wipe the fingerprint sensor gently with a microfiber cloth to ensure there is no dirt, dust, or oil that may be causing the issue. After cleaning, try again.
- Software Reset: Sometimes, a simple reboot or a software reset might resolve the issue. You could also try updating your software if you haven’t done so in a while.
- Factory Reset: If the problem persists, perform a factory reset to rule out software issues. Just make sure to back up your data first, as this will erase all content from the device.
If the sensor continues to fail after these troubleshooting steps, it’s likely time to consider replacing it.
How to Replace the Fingerprint Sensor on Infinix Phones
Replacing the fingerprint sensor on your Infinix device involves several steps. While you can try to fix it yourself, it’s recommended to take your phone to a professional technician to avoid further damage. However, if you’re confident and want to proceed with DIY repairs, here’s a general guide for replacing the fingerprint sensor.
Tools You’ll Need
- Small screwdriver set (preferably precision screwdrivers)
- Plastic pry tool
- Pentalobe screwdrivers (depending on your phone model)
- Soldering iron (in rare cases)
- New fingerprint sensor compatible with your Infinix model
- Adhesive tape or glue (optional)
Step 1: Power Off the Phone
Before beginning the repair process, make sure to turn off the device to prevent electrical short circuits or damage.
Step 2: Remove the Back Panel or Screen
Depending on your Infinix model (X655, X656, X693, X682, etc.), the fingerprint sensor may either be embedded into the back panel or part of the display assembly. In some cases, the fingerprint sensor is integrated into the screen, while other models may have a separate back panel.
- Use a small pry tool to carefully detach the back panel or screen. Some models may have adhesive holding them in place, so be gentle to avoid cracking the glass.
- If you’re working with a front-mounted fingerprint sensor, you may need to remove the entire screen assembly. Ensure you are aware of any delicate connectors.
Step 3: Disconnect the Fingerprint Sensor
Once the back panel or screen is removed, locate the fingerprint sensor, which will either be connected via a ribbon cable or flex connector. Disconnect the sensor from the motherboard carefully.
Step 4: Remove the Old Fingerprint Sensor
If the fingerprint sensor is attached with screws or adhesive, remove those carefully using the appropriate screwdrivers. If the sensor is glued, use a plastic pry tool to lift it from its position.
Step 5: Install the New Fingerprint Sensor
Now that the old sensor is removed, take the new fingerprint sensor and align it correctly with the mounting area. Carefully connect the sensor to the motherboard using the flex cable or ribbon connector.
If the sensor is held in place with screws, ensure that you tighten them properly. If adhesive is used, make sure the new sensor is securely attached without any risk of shifting.
Step 6: Reassemble the Device
After installing the new fingerprint sensor, carefully reassemble the phone in reverse order. Ensure all connectors are reconnected, and the screen or back panel is properly sealed.
Step 7: Test the New Sensor
Once the phone is back together, power it on and go to the settings to enroll your fingerprint. Test the new sensor to ensure that it is functioning properly.
Cost of Replacing a Fingerprint Sensor
The cost of replacing a fingerprint sensor can vary depending on the Infinix model and the location you’re in. On average, here are the potential costs:
- DIY Replacement: If you’re doing it yourself, the cost of the new fingerprint sensor can range from $10 to $30 depending on the model and availability.
- Professional Repair: If you take your phone to a technician or service center, the cost can range between $30 and $70. This cost includes labor, the new sensor, and any other repair services needed.
Keep in mind that prices may fluctuate based on your region, availability of spare parts, and whether you choose an authorized service center or an independent repair shop.
Considerations Before Replacing the Fingerprint Sensor
- Warranty: If your phone is still under warranty, check if fingerprint sensor repairs are covered. Replacing the sensor yourself or through a third-party service provider may void the warranty.
- Third-Party Parts: Be cautious when purchasing third-party fingerprint sensors. Always make sure the replacement part is compatible with your specific Infinix model to avoid compatibility issues.
- Professional Repair: If you’re not familiar with phone repairs, it’s better to have the sensor replaced by a professional to avoid damaging other components.
- Data Backup: Before starting any repair, it’s wise to back up all your data. Although the repair process shouldn’t erase your data, it’s always better to be safe than sorry.
Conclusion
Replacing the fingerprint sensor on an Infinix phone like the X655, X656, X693, X682, X675, X666, X650, X626, X6716, X6816, X695, or X6711 is a relatively straightforward process, but it does require patience and care. If you’re not comfortable with DIY repairs, seeking help from a professional technician is the best course of action to ensure a smooth and safe repair process.
By following the steps outlined in this guide, you can save money and bring your Infinix phone back to full functionality. Always remember to weigh the pros and cons of DIY versus professional repair and consider factors like warranty and cost before making a decision.
