What should I do if the fingerprint unlock fails? What happens when the phone fingerprint unlock fai

1. Reason why fingerprint unlocking failed:

After long-term use, the surface of the fingerprint recognition key is affected by sweat stains, water stains and dust, and the recognition response gradually decreases.

The mobile phone system is faulty, resulting in the fingerprint recognition module being unable to respond to work, and cannot play desktop display and other related work.

The fingerprint recognition module cannot be used if there is a quality problem after pressing and using it for a long time.

When the mobile phone is accidentally dropped or bumped during use, the fingerprint recognition cable of the mobile phone is accidentally broken or the contact is poor, resulting in the fingerprint recognition not working normally.

2. Try the solution:

Wipe the relevant area with a clean paper towel or soft cloth to ensure that the fingerprint recognition area and the large finger of the hand for identification are in a clean and dry environment.

Perform power on and off and system detection to keep the mobile phone system in a normal state, and try fingerprint recognition.

After repeated attempts, the fingerprint module cannot respond, and the fault is explained to the relevant after-sales rolling trouble, and then professional mobile phone fault detection is carried out: fingerprint recognition quality problems, fingerprint recognition internal wiring problems caused by human factors, and professional maintenance and replacement treatment.

If you are using a Huawei phone and your fingerprint cannot be unlocked, you can do it by using the following methods:

1.Please keep your fingers and the unlocking place of the mobile phone clean and free of dirt;

2.If your mobile phone is an under-screen fingerprint, unofficial mobile phone film (anti-privacy film, hydrocondensation film, tempered cover transportation film, etc.) may cause the sensor to receive a weaker signal, affecting your fingerprint unlocking experience.

3.After restarting your phone, delete the original fingerprint and re-enter your finger to improve the unlocking experience.

If the above methods still do not solve your problem, we recommend that you back up your data in advance (third-party applications such as QQ and WeChat need to be backed up separately), and bring your purchase voucher to a nearby Huawei Customer Service Center for testing.
