Why is the fingerprint unlocking of my Huawei Maimangwu not very sensitive recently?

If fingerprint unlocking often fails, you can try the following methods to solve it:

1. If there is dirt on the surface of the fingerprint sensor, clean it up in time. Oil stains and water stains will affect the success rate of unlocking.

2. The weather is cold in autumn and winter, and the finger skin is prone to peeling, wrinkles and new texture depression. I suggest you use another finger to enter the fingerprint to unlock it. You can usually use skin care products to maintain your fingers and reduce peeling and chapping of your fingers. Wash your hands with warm water. Finger texture is smooth, which will be improved after washing hands with warm water or proper exercise.

3. If the fingerprint itself is shallow, please don't click to unlock it with your fingertips. Instead, try to cover the whole fingerprint sensor and the surrounding bright edges with a fingerprint belly, so as to input a stable fingerprint image. The fingerprint characteristic value of finger pulp is the most abundant, which can improve the success rate of unlocking. In addition, you can also record multiple sets of fingerprints and unlock them with fingers with higher success rate.

4. When using fingerprint to unlock, please fully contact the fingerprint sensor. Sliding and wiping with fingers may lead to instability of the collected images, resulting in low success rate of unlocking. For other models, such as Glory 7i, the fingerprint sensor is located on the side of the fuselage. If the mobile phone is unlocked vertically, the finger coverage area may be too small, resulting in a low success rate of unlocking. When unlocking, try to cover the sensor with your fingertips to improve the success rate of unlocking.

5. If there is no vibration prompt when using fingerprint to unlock, it is suggested to try again from another angle. If there is still no vibration prompt, please restart your phone and try again. If there is still no prompt, it is recommended to restore the backup data to the factory. If it still can't be solved, please back up the information and bring the purchase invoice to the nearest outlet for testing.
