Why is my Pixel 7 fingerprint flickering after screen replacement?
Why is my Pixel 7 fingerprint flickering after screen replacement?
I’ve recently had my Google Pixel 7’s screen replaced, and since then, I’ve been facing an annoying issue with the fingerprint sensor. It’s constantly flickering and making it difficult to unlock my phone. I didn’t have any problems with the fingerprint sensor before the screen was replaced. This flickering issue is particularly frustrating because it disrupts my daily use of the phone. Has anyone else experienced this? I’m wondering if this is a common problem after screen replacements, or if there’s something specific about my device that’s causing this malfunction. It feels like a hardware or connection issue, but I’m not sure. What could be the reason for this persistent flickering, and is it a problem that can be resolved without further causing damage to my Pixel 7?

This problem occurred after I had my Pixel 7’s screen replaced. Here’s how I fixed it:
1. Disassemble the phone ensuring every connection is clean and properly placed.
2. Clean the area around the sensor for any physical obstructions.
3. Run a software diagnostic tool to pinpoint potential issues.
4. Reset fingerprint settings by removing and re-adding fingerprints.
5. Monitor battery and performance for any impact on the sensor.
6. Finally, if nothing works, perform a factory reset. Most importantly, using an OEM screen helped me fix the flickering sensor issue.
This exact issue happened to me as well. The repair shop used an aftermarket screen, which caused the flickering. Replacing it with an official Google screen fixed everything. I learned that not all third-party screens are fully compatible with the Pixel 7’s fingerprint sensor. Ensure that the replacement screen is an OEM part to avoid such issues.
A flickering touchscreen sensor usually points to hardware or calibration issues after a part replacement. My best bets:
1. Check for firmware updates since new hardware sometimes needs the latest software.
2. Re-register your fingerprints to recalibrate the sensor.
3. If issues persist, consult Google Support or a certified technician. These steps ensured my Pixel 7 worked perfectly post repair.
I faced a similar issue with my Pixel 7 post screen replacement. Here’s what you can do:
1. Double-check the connections to make sure they’re secure. Loose connections can cause flickering.
2. Recalibrate the fingerprint sensor via the settings menu. Sometimes, a new screen impacts the sensor’s precision.
3. Update your phone’s software; software bugs can affect the sensor.
4. Restart your phone. A simple restart can sometimes clear up glitches.
Whenever I experience such hardware issues, I suspect the parts used first. Third-party screens often don’t match the quality and compatibility of original parts. It turned out I had a non-OEM screen installed. After switching to an original Google screen, the problem vanished. Always check with your repair service about the parts they use.
I’ve been through this. It probably stems from a misalignment of the screen. When I replaced mine, I noticed the screen wasn’t perfectly seated. This caused the sensor to malfunction. Secure the screen properly, clean the sensor area, and ensure no dust or debris is causing interference. These steps resolved the issue for me.
