3. Make sure the finger area you press against the fingerprint sensor is the same as the one
you enrolled on your phone. It is recommended you use the gesture you often use when you
enroll your fingerprint.
6.6 Why do people whose fingerprint patterns are shallow
often fail to unlock the screen using the fingerprint?
Female and children's fingers are slim and their fingerprint patterns are shallow.
1. Slim fingers may not be able to touch the edges of the fingerprint sensor, which may result
in an incorrect fingerprint image collection. (For example, the edges of the Mate7's fingerprint
sensor provide a weak but stable electricity signal. When a finger touches the edges, the
sensor generates sensing capacitance on its surface to produce the fingerprint image. If the
finger doesn't touch the edges properly, the image quality may be poor.)
2. Shallow fingerprint patterns may also cause poor quality fingerprint images.
To solve this problem: Use the finger pad to cover the whole fingerprint sensor and its edges
to enroll clear and stable fingerprints.
6.7 Why does the fingerprint sensor often fail to recognize
my fingerprint and respond slowly when I'm unlocking
the screen?
Circulation in your fingers will deteriorate in high-altitude locations, when sedentary or when
lifting heavy objects, resulting in dry skin and therefore slight changes to the shape of your
fingerprint. Refer to the solutions for dry skin above, e.g. press slightly harder on the
fingerprint sensor and keep your skin moist by breathing onto your fingers or washing your
hands and then wiping them dry.
6.8 Why can't I unlock my phone using my fingerprint
until I restart my phone?
Check how often this occurs. This problem is caused by a software defect rather than the
hardware of the fingerprint sensor or your phone. Please pay attention to the follow-up
version instructions.
6.9 Why can't I unlock the screen using my fingerprint
when my phone is connected to another brand charger?
Please use the standard charger that comes with your phone.
Non-standard chargers have different anti-interference capabilities. The interference from the
power supply will affect the performance of the fingerprint sensor.
