If your phone's screen fingerprint recognition rate is low or unrecognized, try the following methods to exclude:

1. Is a third-party protective film used on the screen? Third-party protective film is not officially certified and cannot guarantee performance. It may  decrease fingerprint recognition rate and is not recommended.
2. Whether there is dirt in the fingerprint recognition area, bubbles or dust in the protective film.
3. Whether the protective film/cover glass of the fingerprint area is scratched or cracked. If so, please try to re-input your fingerprint or replace the protective film/screen.
4. After the new applied/replacement/removal of the protective film, the fingerprint needs to be re-input, otherwise the fingerprint recognition success rate will be affected.
5. If unlock the phone under strong light environment, need to completely cover the recognition area with your finger. 
6. If under low temperature (-5 degrees) environment recognition success rate is low; try to use the fingerprint at room temperature.

Warm tips: due to the influence of environmental factors such as temperature or light, the recognition rate may decline. It is suggested to turn on the face unlocking function to assist unlocking.
