2. Fingerprint changes affect unlocking.

Changes in fingerprints (e.g., dry fingerprints, peeling fingers, sweating, etc.) may affect the success rate of fingerprint unlocking or entry.

3. Check whether you use a third-party film (applicable to screen fingerprint models).

The original film used in the screen fingerprint model has been treated with a special process, which will not affect the fingerprint recognition effect, and the use of a third-party film may affect the success rate of fingerprint unlocking or entry, so it is not recommended to use it, you can go to the customer service center to replace the official film and re-enter the fingerprint.

4. Check whether you use third-party one-click lock screen software.

Based on the security control of the lock screen by the Android system, when the third-party lock screen software is required to unlock the screen, the lock screen password or pattern password must be used to unlock the screen, and fingerprint unlocking or face unlocking cannot be used. It is recommended that you uninstall the third-party one-click lock screen software and use the one-click lock software that comes with your phone.

Reasons for fingerprint entry failure:

When entering, the quality of the fingerprint image obtained by the fingerprint sensor is not up to standard.

When entering, the finger is dry or wet (oily, easy to sweat, wet), and can be removed when touched, which will cause the fingerprint image quality and coverage area obtained by the fingerprint sensor to be substandard.

If the image is not up to standard after pressing the image several times in a row, the fingerprint entry will fail.

The area of the fingerprint is too small, and the entry position is single.

The surface of the fingerprint device is unclean during entry, which affects the quality of the fingerprint.

In the process of fingerprint entry, if you exit halfway without completing the last entry, the fingerprint entry fails.

Note: Please try to avoid entering fingerprints while charging.

Please note the following when entering:

When entering fingerprints, please do not slide your finger when pressing, so that a clear fingerprint can be collected.

When entering, please keep your fingers and fingerprint device clean. The fingerprint sensor is recognized by the fingerprint pattern and its fine capacitance difference, so please keep the finger and fingerprint sensor clean when entering, sweat, water stains, and dirt will affect the entry of the fingerprint template, and the sensor will also intelligently identify and prevent the user from entering.

When entering fingerprints, please press with appropriate force, use fingers to enter fingerprints on and around your fingertips, place your fingers on the fingerprint reader of your mobile phone, and lift your fingers to repeat the entry after feeling the vibration. (There are many fingerprint characteristic values of the finger belly, and it is also a common posture).

It is recommended not to use your finger to enter repeatedly in the same position, and to expand the fingerprint entry area as much as possible. The working principle of fingerprint recognition is to match the fingerprint entered before, so please use different positions of your finger to enter according to the prompts, the larger the area of fingerprint entry, the higher the probability of successful comparison, and you need to avoid repeatedly clicking and entering with the same area when entering fingerprints.

When entering, try to use the posture you normally used to unlock. Fingerprint unlocking needs to be matched and compared with the previously entered fingerprint information, and it is recommended to use the usual unlocking posture when entering, so as to improve the success rate when unlocking.

In the process of fingerprint entry, if you exit halfway without completing the last entry, the fingerprint entry will fail, please ensure that the last step of fingerprint entry is completed. The last step of fingerprint entry prompt is as follows: please complete the fingerprint information, after the entry is completed, the interface will pop up the entry success interface, please click OK.

Then restart the phone and try it, it should be a problem with the phone.

You can see if the skin of your fingers is worn, so you can try another finger.

You shouldn't have a problem with the fingerprint touch, right?,Clean the fingerprint touch first.,If it doesn't work, delete the original fingerprint and record it again.。

It may be that there is a problem with the hardware of fingerprint recognition, and it is recommended to repair it.

1. It may be that the mobile phone system has crashed, stuck and other faults, you can restart the mobile phone to see if it has returned to normal.

2. It may be that the recorded fingerprint cannot be recognized, it is recommended to enter "Settings", click "Password and Security", enter "Fingerprint Unlock", delete the existing fingerprint and add it again.

3. If the fingerprint is used frequently and the fingerprint storage file is updated when the fingerprint is full, the fingerprint storage space may be full, resulting in the unavailability of the fingerprint hardware. You can delete infrequently used fingerprints in fingerprint management, only keep or enter 1-2 commonly used fingerprints, and then restart the phone to try it.

4. If it doesn't work, you can back up the mobile phone data and software, and then restore the factory settings, under normal circumstances, if it is a software problem, it can be solved.

5. There may also be hardware failures such as wiring, which cannot be solved by yourself, so it is recommended to send the mobile phone to the after-sales service for testing and maintenance.
