Step-by-Step Guide to Redo Fingerprint on Samsung S21
Redesigning your fingerprint on the Samsung Galaxy S21 is a straightforward process. Follow the steps below to ensure that you do it correctly.
Prepare Your Device
Before you start, it’s always good practice to ensure that your device is ready for the process:

Removing Old Fingerprints
Before adding new fingerprints, consider deleting any old or unresponsive ones:
- In the Fingerprint menu, you will see a list of all stored fingerprints.
- Tap on the fingerprint you wish to delete. For instance, if you want to remove your old fingerprint #1, tap on it.
- Select Remove. Confirm the action when prompted by tapping on OK.
Adding a New Fingerprint
Now, let’s add a new fingerprint:
- Go back to the Fingerprints section in Biometrics and Security.
- Tap on Add Fingerprint. You might need to input your PIN, pattern, or password again.
- Position Your Finger: Follow the on-screen instructions. Start by placing your finger on the fingerprint sensor located beneath the display. This usually involves a sequence of lifts and presses.
Digging Deeper into the Fingerprint Registration
As you register your fingerprint, it’s essential to get a good scan:
- Angle Variations: Rotate your finger slightly after each lift and press to capture different angles, ensuring a complete scan of your fingerprint.
- Complete Coverage: Make sure the sensor reads all areas of your fingerprint, encompassing the edges and center.
- Stay Consistent: If you have added multiple fingerprints, try to keep them consistent by using the same finger or fingers for easier recognition later.
After following all the instructions, once you have finished registering your fingerprint, you will receive a notification indicating that the process has been successfully completed.
Testing Your New Fingerprint Settings
Once you’ve added and saved your fingerprints, you should test them:
- Lock Your Device: Press the power button to lock your Galaxy S21.
- Unlock Using Fingerprint: Try unlocking the phone using the newly registered fingerprint. If successful, your device should unlock with minimal effort.
- Repeat for Other Fingerprints: If you’ve added multiple fingerprints, test each one to ensure they all work seamlessly.
Troubleshooting Common Fingerprint Issues
Even after redoing your fingerprints, you might face occasional hiccups. Below are solutions to common fingerprint-related issues:
Fingerprint Not Recognized
If your Galaxy S21 fails to recognize your fingerprint, consider these troubleshooting steps:
- Clean the Sensor: Ensure that the fingerprint sensor area is clean and devoid of smudges or dirt that might interfere with detection.
- Moisture or Dirt on Your Finger: Wipe your fingers to ensure they are clean and dry before scanning.
- Check Finger Position: Sometimes, the angle at which you place your finger matters. Make sure you are following the recommended techniques while adding fingerprints.
Performance Lag**
If you notice a lag in performance when using the fingerprint sensor:

What is fingerprint redo and why is it important for Samsung S21 users?
Fingerprint redo is a feature that allows users of the Samsung S21 to re-register their fingerprints for enhanced security and convenience. This process is particularly important for users experiencing issues with their current fingerprint recognition, which may be due to damage to the sensor, changes in the user’s fingers, or the accumulation of dirt or oil on the sensor.
Re-registering fingerprints can improve the device’s ability to quickly and accurately recognize the user, thereby providing a smoother unlocking experience. Additionally, mastering the fingerprint redo process can help users maintain secure access to their device and the sensitive information stored within it.
How do I redo my fingerprint on a Samsung S21?
To redo your fingerprint on a Samsung S21, start by navigating to the device’s ‘Settings’ menu. Once there, scroll down to ‘Biometrics and security’, then select ‘Fingerprints’. You will be prompted to enter your current PIN, pattern, or password to proceed.
After verifying your security method, you can either delete the existing fingerprints or simply add new ones. Follow the on-screen instructions to register your fingerprints again, ensuring to position your finger at different angles for optimal recognition. Once you’ve completed the registration, your new fingerprints will now be used for unlocking your device.
What should I do if my fingerprint sensor is not recognizing my fingerprint properly?
If your fingerprint sensor is not recognizing your fingerprint properly, consider cleaning both the sensor and your fingers. Dirt, moisture, and oil can create a barrier that inhibits accurate scanning. Use a soft, dry cloth to gently wipe the sensor to ensure it is clean. Also, make sure your fingers are dry and clean when attempting to use the sensor.
If cleaning the sensor does not resolve the issue, you may want to redo your fingerprint registration. Delete the current fingerprints stored on your device and re-register them, making sure to follow recommended techniques for capturing fingerprints. Sometimes, repositioning your finger at various angles can lead to better success during the registration process.
How many fingerprints can I register on my Samsung S21?
The Samsung S21 allows users to register up to four different fingerprints. This limitation ensures that users can still access their devices securely while accommodating multiple fingers if desired. You can use different fingers or register multiple prints from the same finger to improve the likelihood of a successful scan.
If you find that your fingerprint recognition is still inadequate after registering the maximum number of fingerprints, consider adjusting your registration technique. Incorporating more angles or parts of your finger can enhance the way the sensor reads your prints, leading to better recognition rates.
Can I use fingerprint redo in conjunction with other unlocking methods?
Yes, you can use fingerprint redo alongside other unlocking methods such as PIN, password, or pattern lock. Samsung devices are designed to provide multiple layers of security, allowing users to select the most convenient method for their needs. This multi-faceted approach enhances overall security while allowing flexibility in access.
In a situation where the fingerprint sensor is not functioning, users can easily switch to their alternate unlock method. By enabling multiple security options, you are better protected against unauthorized access while ensuring that you can still gain entry into your device even if one method encounters issues.
What should I do if I forget my PIN or password after redoing my fingerprint?
If you forget your PIN or password after redoing your fingerprint, don’t panic. Samsung devices provide a safety net that allows for recovery through various methods. You can use the ‘Find My Mobile’ service that Samsung offers if your account is set up for it. This service can help you unlock your device remotely or reset your credentials.
If you are unable to access your device through Find My Mobile, you may need to perform a factory reset. Keep in mind that this will erase all data on the device. To prevent such issues in the future, it is advisable to record your credentials securely and to use Samsung’s features for password recovery when setting up security options.
