Fingerprint sensor on my samsung A16 5G stopped working abruptly 10 days after the purchase. Tried all those stupid suggestion of cleaning the sensor, resetting the mobile, the problem is seen again.

Such a pity that a company like Samsung can still not get this right. There is a reason why Chinese mobiles are beating them. I chose Samsung over the Chinese brands despite of less features in the price range primarily because of data security. However, Samsung never fails to make you regret that.

Hope to see meaningful response followed by a conclusive solution.

I understand your frustration. It's indeed disappointing when a brand like Samsung, known for its quality and reliability, faces such issues.
Given that basic troubleshooting steps haven't resolved the problem, it strongly suggests a hardware issue with the fingerprint sensor itself.
Here's what I recommend:
* Contact Samsung Support: Explain the issue in detail, including the fact that the problem persists despite your attempts to fix it.
* Warranty Claim: Since the issue occurred shortly after purchase, it should be covered under warranty. Insist on a repair or replacement of the device.
* Service Center Visit: If contacting support doesn't yield a satisfactory resolution, visit an authorized Samsung service center. They can diagnose the issue and provide a proper repair or replacement.
Regarding your concerns about Chinese brands:
* Data Security: While concerns about data privacy with Chinese brands exist, Samsung has also faced its share of security issues. It's essential to research and choose brands with robust security measures and a good track record.
* Quality Control: Quality control issues can occur with any brand, not just Chinese manufacturers.
I hope this helps. Remember to be persistent with Samsung support to ensure your issue is resolved effectively.

Dear Samsung Member,

Greetings from Samsung Customer Support!

As per your concern, we would request you to kindly perform the following steps to resolve your issue.

● Ensure that your fingers are clean and dry.
Note: If the skin on your fingertips is peeling or cracking, or your fingerprint is difficult to capture, the fingerprint ID on your phone may not work.

● If your fingerprints fail to unlock the phone while the phone is recharging, remove it from the charger and try again. If you are charging the phone with a charger and data cable from other brands when you use fingerprints to unlock the phone, they may interfere with the fingerprint sensor and cause the recognition to fail.

● Clean the fingerprint sensor with a soft cloth. Make sure the fingerprint sensor is dry and free from any debris that may cause the sensor to be unable to recognize the fingerprint.

● Remove the current fingerprint and set up the fingerprint again. When you touch the sensor to set up a fingerprint, make sure you set the entire fingerprint, including the outer area of your fingertip. Setting the entire fingerprint area enables successful fingerprint recognition with any grip.

● How to remove Fingerprint: Path: Settings> Biometrics and Security> Fingerprints> Fingerprint1> Remove> Remove again to confirm.

● How to Set up Fingerprint: Path: Settings>Biometrics and Security> Fingerprints> Fingerprint> Scan your fingerprint> Place your finger on the sensor, then lift it off when you feel a vibration> Continue> Reposition your finger each time to capture the edge of your fingerprint> Done> Fingerprint added successfully.

● Try Safe mode: https://www.samsung.com/in/support/mobile-devices/safe-mode-on-samsung-phones/

● Update the software if available: https://www.samsung.com/in/support/mobile-devices/samsung-galaxy-smartphone-how-to-update-software/

● You can reset your device by following the steps.
1. Kindly create a data backup of your device via the SMART switch mobile application or http://www.samsung.com/in/support/smartswitch pc suite.
2. Remember the Google password before resetting the device because it is required during initial setup.
3. If you do not remember then advise to reset (Forgot password) his/her Google account.

Path: Settings> General Management.>Reset>Temporary cloud backup or External storage backup>After backup tab on Factory data reset to reset your device to its factory default settings.
This will erase all data, including files and downloaded apps.

If the issue still occurs, please visit the service centre for a physical inspection of your device. You can locate your nearest service centre with this given link: https://www.samsung.com/in/support/service-center/

Warm Regards,
Samsung Customer Support
