6.2 Why does it takes a long time to unlock the screen after
my phone has been used for a certain period?
1. Your fingers may become dry in autumn and winter. In this case, you can press your finger
against the fingerprint sensor more strongly and keep your finger moderately humid by
blowing hot air to it or washing it.
2. The blood circulation speed decreases when you sleep and the fingerprint pattern gets
shallower. Even though the fingerprint characteristics remain unchanged, it may feel smoother.
In this case, you need to press harder.
3. The working temperature of the fingerprint sensor is from –20°C to +75°C.
6.3 What can I do to successfully unlock the screen if my
fingers are dry?
When your fingers are dry naturally, in dry seasons (autumn and winter) or in plateau areas,
during rest, or after you carry heavy objects, you may fail to unlock the screen using your
fingerprint.
Fingerprints increase the friction between your finger and the object you want to touch. If
your fingerprint is too dry, the friction will decrease.
Solution:
1. Press your finger against the fingerprint sensor more strongly.
2. Keep your fingers moderately humid by blowing hot air onto them or washing them.
6.4 What can I do to successfully unlock the screen if my
fingers are wet or sweaty?
If your fingers are sweaty or still wet after you wash your hands, you may fail to unlock the
screen using your fingerprint.
To solve this problem: Wipe your fingers with tissues and ensure your fingers are free of
water or sweat.

6.5 Why does my phone fail to read my fingerprint?

1. Your phone may fail to read your fingerprint if your finger is too dry, sweaty, wet, or is
damaged. Wipe your finger and try again. If your fingers are dry, you may need to press your
finger against the sensor more strongly.
2. You can try enrolling your fingerprint again. While you are enrolling your fingerprint, use
the gesture you often use, enroll as many fingerprint areas as possible, and avoid enrolling the
same area of your fingerprint, so the enrolled fingerprint image will be consistent with that
read by your phone when you press your finger against the fingerprint sensor.
