6.22 Why can't I unlock my phone or register my
fingerprint when I swipe my finger on the fingerprint
sensor?
Your phone's fingerprint sensor is pressure-sensitive. You only need to slightly press your
finger against the sensor to unlock the screen or register your fingerprint. Don't scratch the
fingerprint sensor.
6.23 Why do I have to set an unlock password before I
register my fingerprint?
If for any reason you can't use your fingerprint to unlock the phone, you can use the password
to unlock it and update the registered fingerprint.
6.24 Why does my phone read my fingerprint slowly in
winter or when the weather is dry?
Your fingerprint changes with different environmental elements, such as temperature,
humidity, acidity, and oiliness. Fingerprint enrolling and reading are also affected by
fingerprint patterns.
Before enrolling your fingerprint, clean your fingers. Keep your fingers in moderate humidity
and moist condition. For example, if your fingers are too dry, your phone may fail to identify
your fingerprint.
If your fingers are sweaty, it is recommended you use tissues to wipe them before you unlock
the screen.
If your fingers are dry, you may need to press your finger against the sensor more strongly.
6.25 How do I unlock the screen when I am not able to use
the fingerprint feature?
Before setting up the fingerprint unlock feature, you must set the screen unlock method to
Number password or Combined password and create a screen unlock password. If your
phone can't recognize your fingerprint or you are unable to use the fingerprint unlock feature,
you can unlock the screen by entering the preset password.
6.26 How do I delete the fingerprints registered on my
phone?
Go to Settings > Security > Fingerprint and enter the unlock password. Select the
fingerprints you want to delete in the fingerprint list and touch DELETE.
