What should I do if I am unable to recalibrate my fingerprint sensor with a replacement screen?

From my experience, the issue might lie with the fingerprint sensor itself. I visited a certified technician who specialized in my smartphone model. They found a slight damage in the sensor which occurred during the screen replacement. Once they replaced the fingerprint sensor, it worked without any issues.

I realized that the way I positioned my finger during recalibration mattered a lot. I had to ensure I covered all angles lightly but steadily. Pressing too hard or just covering the center wouldn’t work. Moving my finger slightly during the setup process solved the problem for me.

Once I dealt with the same issue, performing a factory reset turned out to be the solution. I recommend backing up your data first, as this will erase all information. After the reset, I could recalibrate the fingerprint sensor successfully. This approach seems to reset all settings and clear up various hardware-related bugs.

When I encountered this problem, accessing the developer options helped me fix it:
1. Go to ‘About phone’ in your settings and tap the build number seven times to unlock developer options.
2. In developer options, locate settings related to sensors.
3. Use the newly available options to recalibrate the fingerprint sensor.
This trick did it for me, and it restored the sensor’s functionality.

In my situation, the replacement screen was the culprit because it didn’t meet the required specifications. After ordering a screen from a reputable supplier who guaranteed compatibility, and having it installed by a professional, the fingerprint sensor recalibrated without any issues.

Updating the software helped me when I faced this problem. You can try checking for any available updates:
1. Go to the settings menu and find software updates.
2. Install the latest update.
3. Attempt the recalibration process once updated.
This fixed the fingerprint sensor issue for me after installing the latest software version.

I had the same problem, and the first thing that you should verify is the compatibility of the replacement screen. Sometimes third-party screens can create issues. Make sure all connections are secure and properly attached. Simply reconnecting everything may solve the problem.

In my case, the adhesive used during the screen replacement was interfering. After returning to the repair shop, the technicians found that some adhesive was obstructing the sensor. They fixed it carefully, and the fingerprint sensor recalibrated successfully. You might want to have the installation checked again.

I faced a similar issue, and here’s a step-by-step guide that helped me resolve it:
1. Ensure your phone’s firmware is up-to-date from the manufacturer’s official website.
2. Download and install any available official calibration software for your phone brand. Sometimes, these tools are only available at authorized service centers, so visiting one might be necessary.
3. Clean the fingerprint sensor area thoroughly to ensure no dust or dirt is interfering.
Following these steps resolved my issue with the fingerprint sensor.
