Fingerprint Sensor Issue After April 2025 Update on S23 FE

[krishnagangrade]

Hi Team,

I’m Krishna Gangrade, using the Samsung S23 FE since March 2024. After installing the April 2025 security update, I’ve been facing a serious issue with the fingerprint sensor.

Before the update, the sensor worked flawlessly. Now, it frequently fails to recognize my fingerprint, and there's no clear pattern—it sometimes works but mostly doesn't. On top of that, I’ve noticed that I have to restart my phone regularly just to get the fingerprint sensor to function temporarily.

This has impacted both the usability and security of the device.

I’ve tried the following steps already:

• Cleaned the sensor area
• Deleted and re-added fingerprints
• Restarted the device multiple times

Unfortunately, the problem still exists.

Device Details:

• Model: Samsung Galaxy S23 FE
• Security Patch: April 2025
• Location: Indore, Madhya Pradesh

Dear Samsung Member,

Greetings from Samsung Customer Support!

At Samsung, we always aim to provide impeccable services to our customers, and we highly regret that you feel this way.

Please follow these easy troubleshooting steps which may help in resolving this issue:

● 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.

● 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 the password then advise to reset (Forgot password) your Google account.

Path: Settings> General Management.>Reset>Temporary cloud backup or External storage backup>After backup tap 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/
