"IPhone5S fingerprint identification speed slows down the solution"
1, adjust the position
Input, not only need to position the finger vertically, but also need to adjust the angle, such as 45 degrees, because you use a single hand to unlock the phone, the thumb is often not vertical.
2, the use of different fingers
Touch ID can be entered up to 5
Finger fingerprint, if the fingerprint of a finger is not so obvious that it is not easy to identify, you'd better input a few more to increase the recognition rate.
3. Make sure the finger touches the metal ring.
Touch ID sensor is not just a home button, the next metal ring is also an increase in the identification rate of one of the components, so use to ensure that the finger contact with the metal ring, rather than dangling in the center of the home key. If the Touch ID is still unavailable after a good fingerprint entry is completed, there are several possible scenarios:
1 finger or mobile phone damp, cold environment
The Touch ID sensor is identified by the static and heat of the finger, so it is not available if it is severed. Of course, if your finger or home button is stained with water stains, it may also cause the identification is not normal, then make sure that the fingers and mobile phone is dry. In addition, the cooler environment can also affect the work of the sensor.
2) in Safe mode
If the five scan is unsuccessful, or if the device is rebooted, the Touch ID feature will need to be unlocked before using a password.
3) the sensor becomes dirty
If the home key becomes dirty, it also has a significant effect on fingerprint recognition, especially after contamination of the finger grease. At this point you can try to use anti-static soft cloth to clean the home button, if still not, you need to go to the Apple Customer service to detect.
