1. Please check whether you use a third-party protective film, the third-party protective film is not officially certified, can not guarantee the performance, may cause the fingerprint recognition rate to be reduced, it is recommended that you use the official protective film;

2. The protective film of the fingerprint area Whether the touch screen is scratched or broken. If yes, please re-enter the fingerprint or replace the protective film screen;

3. Whether the fingerprint area is dirty, there are bubbles in the protective film, dust, etc. If so, it is recommended to clean and replace the protective film;

4. After removing the protective film, you need to re-enter the fingerprint, otherwise the fingerprint recognition effect will be affected.

1. After unlocking with the preset pattern digital password, delete the previous fingerprint again, and set the fingerprints of other fingers to see;

2. When re-entering, try to stick to the screen as hard as possible, and record fingerprints of the same finger at different angles, which can improve the unlocking rate and security;

3. When unlocking, press your finger slightly the position of the fingerprint icon, and stay for a little (don't lift your finger too fast) to increase the unlocking rate.

1. If unlocked in strong light, please use your finger to completely cover the fingerprint recognition area;

2. At low temperature (less than -5), the recognition success rate will decrease, and it is recommended to turn on the face recognition function to assist in unlocking in a low temperature environment.

I couldn't unlock my phone with my fingerprint last night, and I couldn't unlock it with a password. I was in a hurry at the time, but then I used the phone restart function to unlock it with my fingerprint.

Log in with other unlocking methods first, and then delete the saved fingerprints, if there is no other unlocking method, the mobile phone interface can't enter, and you can only go to the repair shop to unlock it. It is recommended that graphics, passwords, fingerprints, password problems, face brushing, and everything that can be set in the future.

It's better to change a mobile phone, but if you don't have the money, you can fix it, as long as it's more than two hundred, it's not expensive, it mainly depends on how you choose, and it may be better to change your phone.

If you use your fingerprint continuously, it will be abnormal, or it may be that there is a problem with the phone, delete the fingerprint on the phone and re-do it, try it.

What mobile phone, Android's can change the fingerprint key, Apple can't, Apple can't change the key, you can only reconnect.

It is likely that the cable is broken, and it can be repaired in about a hundred years. Its practical digital unlocking is also possible, and there is no need to waste money to fix it.

If the fingerprint recognition of the mobile phone is abnormal, it may be that the fingerprint recognition is no longer available, or it may be temporarily out of order.

The fingerprint of the mobile phone is generally not wrong, it may be that the finger is not clean or there is water, if it does not work, change it to a digital password.

Log in with other unlocking methods first, delete the saved fingerprint, and set it up again.

Just bought it back, you have two unlocking methods at the minimum, and the fingerprint can be unlocked with a password if there is an abnormality!

First of all, clean up the fingerprint unlock, if it does fail, you can only replace the module, ** is not very expensive.

Maybe your fingers got water or something else, or maybe your phone is broken.

Fingerprint unlocking is more convenient, and it is too useful, so use the password to unlock and take a screenshot.

Fingerprint recognition is generally not a problem, unless you are not doing it yourself.

My phone is like this, I can be re-admitted, and if it doesn't work, I can change the fingerprint key.

If there is no problem with the fingerprint, it is a problem with the machine, go to the after-sales service to check it.

Log in with a different login method and then set up a new fingerprint.

First of all, clean up the fingerprint to unlock, and make sure that the module can only be replaced if it fails.

Then use the password to enter it first, and try it again after a while, it is not recommended to fix it.

The fingerprint recognition device is abnormalThis is caused by an error in the computer's fingerprint recognition device settings, and the specific fixes are as follows:

1. First click on the computer icon on the desktop of the electric ant clear brain:

2. Select "Device Manager" in the main menu of "System".

3. In the "Device Manager" that opens, double-click the left mouse button "Biometric Device:".

4. The dialog box appears to select the restore device, and then click on the next step to rent a piece:

5. Finally, you can see that the computer's fingerprint recognition device has been working normally at this time

What's going on with the failed to add fingerprint:1If the finger slides quickly, the quality of the fingerprint image obtained by the fingerprint sensor will not meet the standard, resulting in the entry failure, it is recommended that you place your finger in the fingerprint sensing area and wait for a while when recording.

2.If there are sweat, water stains, dirt, etc. in the finger or fingerprint sensor identification area, the sensor will also intelligently identify it, affecting the entry of fingerprints. 3.

If you exit the entry interface or keep the screen on for more than 10 minutes, which will cause the entry to fail, we recommend that you re-enter the fingerprint and complete the fingerprint entry in time.

Reasons why fingerprints cannot be recorded:

1. When entering fingerprints, the fingers slide quickly, which will cause the quality of the fingerprint image obtained by the fingerprint sensor to be substandard, and the input will fail, so it is recommended to place the finger in the fingerprint sensing area and wait for a while.

2. If there are sweat, water stains, dirt, etc. in the finger and fingerprint sensor identification area, the sensor will also intelligently identify it, which will affect the entry of fingerprints, so it is recommended to clean it up.

3. If you exit the entry interface or the screen is not operated for a long time, if you exit the entry interface or keep the screen on for more than 10 minutes, it will lead to the failure of the entry, it is recommended to re-enter and complete the fingerprint entry in time.

4. After exercise, swimming, or other changes that affect the condition of the fingerprint, resulting in inaccessibility. Wash your fingers and dry them with a clean, lint-free cloth.

5. The finger is offset from the recognition area, and the finger should completely cover the main screen button, and do not press and hold it hard when the fingerprint is scattered and scanned.

Your mobile phone is an under-screen fingerprint, and unofficial mobile phone films (anti-privacy film, hydrogel film, tempered film, etc.) may cause the sensor to receive a weaker signal, affecting the user's fingerprint entry experience.

Fingerprint lock technology:

Most mobile phone manufacturers also pay more attention to fingerprint unlocking, looking at the types of fingerprint recognition technology, there are no more than three: capacitive fingerprint recognition, optical finger pattern recognition and ultrasonic fingerprint recognition. <>

The fingerprint recognition device is abnormalThis is caused by an error in the computer's fingerprint recognition device settings, and the specific fixes are as follows:

1. First click on the computer icon on the computer desktop:

2. Select "Device Manager" in the main menu of "System".

3. In the "Device Manager" that opens, double-click the left mouse button "Biometric Device:".

5. Finally, you can see that the computer's fingerprint recognition device has been working normally at this time

Fingerprint recognition modules are divided into three categories as far as I know. One is the optical fingerprint module ZAZ-010-B, the second is the capacitive fingerprint module ZAZ-020, and the third is the RF fingerprint module ZAZ-030-B. Through these fingerprint modules, the second-generation fingerprint reader and fingerprint lock have been developed.

If your phone's fingerprint sensor fails, it is recommended that you do the following:

1.Shutdown and restart attempts;

2.Re-register fingerprint attempt after deleting the previous fingerprint;

3.If it doesn't work, check whether there is a new version of the mobile phone system and try to upgrade;

If the problem persists, please bring the purchase invoice, repair card and machine to the Samsung service center for professional after-sales engineers to help test.

According to the fingerprint, it is always wrong, there are the following reasons, the first is that your fingerprint is not clear enough, so it will always be wrong, and the second is that your fingerprint is possessed by water, and it is easy to be unidentified.

There is a problem with the fingerprint input, resulting in a mismatch with the fingerprint stored in the A7 chip, resulting in unlocking failure.

1. There is a problem with the home button and related parts of the iPhone6, and the fingerprint cannot be scanned correctly.

2. Fingers with sweat or powder, or oily fingers. Causes an error in scanning the fingerprint because the iPhone6 is a capacitive fingerprint unlock, which has this drawback.

3. Finger injuries have left scars.

4. The unlocked finger is not the same as the finger you entered before.

5. It may be that the fingerprint is too shallow.

Second, there is a problem with the stored fingerprint sample.

1. Whether the entered fingerprint has been damaged (it may be software or hardware damage).

2. The fingerprint identification sample is not standard when entering, and the fingers are oily or wet, resulting in a mismatch of fingerprints when unlocking.

Precautions when entering fingerprints].

1. Keep your fingers dry when entering fingerprints.

2. Fingerprints are entered on both the left and right hands.

3. When unlocking, if your fingers are wet, or there are food crumbs sticking to them, or your fingers are very oily, wipe your fingers dry with a paper towel, which can greatly improve the success rate of fingerprint unlocking.

Fingerprint recognition is more precise, wipe off the fingerprint module and hand to try, whether your fingers have peeled or fingerprints worn or something recently, use the most commonly used grip posture when recording fingerprints, enter as much finger area as possible, it is best to use fingertips, do not use fingertips, these will improve the success rate of unlocking.
