Why is the fingerprint scanner not working after replacing the screen on my Pixel 6 Pro?
I recently replaced the screen on my Pixel 6 Pro, and now the fingerprint scanner is no longer working. Before the screen replacement, the fingerprint sensor was functioning perfectly, but since the repair, it no longer recognizes my fingerprint. I’m extremely frustrated because I’ve tried to re-register my fingerprint multiple times, but it keeps failing. I have also rebooted the device and ensured that the screen replacement was done correctly. It’s puzzling and inconvenient, especially because I heavily rely on the scanner for unlocking my phone and accessing secure apps. Why is this happening, and what could be the underlying cause?

Another factor that could be causing the issue is the use of a third-party or non-original screen. The Pixel 6 Pro’s fingerprint sensor is intricately designed to work with the original screen hardware. Third-party screens might not have the necessary components or the correct thickness, leading to faulty fingerprint recognition. Always ensure you use genuine parts when replacing essential components like the display.
There’s a chance that dust or debris might have settled on the fingerprint scanner beneath the new screen. Even small particles can interfere with the scanner’s ability to function effectively. Cleaning the screen with a microfiber cloth and a gentle cleaning solution might help. Make sure to turn off your device before attempting any cleaning to avoid any damage.
Sometimes, the new screen might come with a protective layer or coating that interferes with the fingerprint scanner’s accuracy. If there’s a screen protector on your new screen, it might be causing the issue. You can try removing the screen protector and then adding your fingerprint again to see if it resolves the problem.
In some cases, the replacement screen might have its own inherent defect. Quality control can miss defects occasionally, even with reputable parts. If the above solutions don’t work, consider contacting the seller or manufacturer to discuss the possibility of a defective screen. They might offer a replacement or refund.
If you performed the replacement yourself, it could be due to a faulty installation. Sometimes, even a tiny misalignment or improper handling during the procedure can cause sensor failures. In that case, you might need to revisit each step carefully and ensure everything is in place. Alternatively, seeking professional assistance for reinstallation may lead to better results.
In rare instances, replacing the screen might have led to damage to the internal components of the fingerprint scanner itself, whether from static electricity or mishandling. If internal damage is suspected, professional repair services would be required. It would involve more intricate diagnostics and possibly replacing the fingerprint scanner unit entirely.
It’s also possible that a software glitch is causing the fingerprint scanner to malfunction. Sometimes, after such modifications, the device’s software, including the drivers responsible for the fingerprint scanner, may need recalibration or reinstallation. You can try updating your phone to the latest firmware, as Google often releases patches that enhance hardware compatibility. Here’s how you can do it:
1. Go to ‘Settings’ on your phone.
2. Scroll down to ‘System’ and tap on it.
3. Select ‘Software Update’ and follow the prompts to check for and install any available updates.
One common reason why the fingerprint scanner might not work after replacing the screen on your Pixel 6 Pro is because of improper hardware alignment. During the screen replacement process, it is vital that the fingerprint scanner assembly is correctly positioned and aligned with the new screen. If it’s even slightly off, the sensor might struggle to capture and verify your fingerprint accurately.
