How to fix iPhone 5s fingerprint recognition problems

As the most popular smartphone this year, the innovative highlights of iPhone 5s are mainly reflected in the Touch ID fingerprint recognition function.Although some previous laptops and mobile phones were equipped with similar functions, the fingerprint recognition sensor did not have any influence due to its abrupt shape and low recognition rate, the iPhone 5 S is cleverly integrated into the body, and the recognition experience is also enhanced.

However, as the usage time increases, it seems that Touch ID fingerprint recognition has also encountered some minor problems. users complain that the recognition speed is slow and the accuracy is reduced, which affects the user experience. It is certain that the fingerprint recognition sensor used by Apple is very advanced, but still not perfect, we may try to solve it in a few small ways.

First, ensure the most accurate fingerprint Input

Before using the Touch ID function for the first time, you should first input fingerprint information, which is an important part of recognition accuracy. Fingerprint input is divided into two parts. The first is general input, which requires fingers to be placed multiple times. The second is to adjust the input at different positions, which helps increase the recognition rate, after all, you cannot ensure that your fingers are placed in the same position each time. The following are the key points of fingerprint input:

Adjust position: when entering the data, you not only need to place the finger vertically, but also adjust the angle, for example, 45 degrees, because the thumb is usually not vertical when you unlock the phone with one hand.

Use different fingers: Touch IDS can be used to input a maximum of five finger fingerprints. If the fingerprints of a finger are not clearly easy to recognize, you 'd better enter a few more to increase the recognition rate.

Make sure that the finger is in Touch with the metal ring: The Touch ID sensor is not just the Home key, but the metal ring next to it is also one of the components that increase the recognition rate, so make sure that the finger is in Touch with the metal ring during use, instead of hanging in the center of the Home Key.

If the Touch ID still cannot be used after a good fingerprint entry is completed, it may be in the following situations:

Wet fingers or mobile phones, and the environment is too cold: The Touch ID sensor is identified by the static electricity and heat of the fingers, so it cannot be used if the contact is disconnected. Of course, if your finger or Home key is stained with water stains, it may also lead to abnormal identification, then make sure that your fingers and mobile phone are dry. In addition, the cold environment also affects the work of the sensor.

In safe mode: if the five scans fail or the device is restarted, you must unlock the password before you can use the Touch ID function again.

Sensor dirty: if the Home Key is dirty, fingerprint recognition will also be greatly affected, especially after the fingers are contaminated with oil stains. In this case, you can try to clean the Home key with an anti-static soft cloth. If it still does not work, you need to check it at Apple's customer service.
