What is the reason why the Apple 5s fingerprint function cannot be turned on?

Before using the Touch ID function for the first time, it is first recommended to enter fingerprint information, and this step is an important part of the recognition accuracy. Fingerprint entry is divided into two parts, the first is general entry, which requires multiple finger placements; The second is to adjust the input in different positions, which can help increase the recognition rate, after all, you can't guarantee that your finger will be in the same position every time you use it. Here are a few key points when fingerprinting:

Adjust the position: When typing, you not only need to place your finger vertically, but also need to adjust the angle appropriately, such as 45 degrees, because when you use one hand to unlock the phone, the thumb will often not be vertical.

Use different fingers: Touch ID can record up to 5 finger fingerprints, if the fingerprints of a finger are not obvious and not easy to recognize, you had better enter a few more to increase the recognition rate.

Make sure your finger touches the metal ring: The Touch ID sensor is not just the Home button, the metal ring next to it is also one of the components that increases the recognition rate, so make sure your finger touches the metal ring when using it, and not place it in the air on the Home button**.

If Touch ID is still unusable after a good fingerprint entry, it could be one of the following scenarios:

Wet fingers or mobile phones, too cold environments: Touch ID sensors are identified by static electricity and heat from fingers, so they cannot be used if they are severed. Of course, if your finger or home button is stained with water, it may also cause the recognition to be abnormal, so make sure that your finger and phone are dry.

In addition, a colder environment can also affect the operation of the sensor.

In Safe Mode: If you fail to scan five times or restart your device, you will need to unlock it with a passcode before you can use the Touch ID feature again.

Dirty sensor: If the home button gets dirty, it can also have a big impact on fingerprint recognition, especially after finger grease stains. At this time, you can try to use an anti-static soft cloth to clean the home button, if it still doesn't work, you need to go to Apple's customer service for testing.

Maybe someone changed the home button for you.

Method.

1. Delete the original fingerprint.

2.After deleting the original fingerprint, click on the "Add Fingerprint" option to add a new fingerprint.

3.Then see if you want to re-enter a new fingerprint, and if not, read on.

Method. 2. Reset your phone settings.

1.If the above method doesn't work, you can try to restore your phone's settings. If your phone is jailbroken, don't use this method. Next, please click on the "General" option in the list of settings as shown in the image.

2.Find the "Restore" option at the bottom of the general list and click to enter.

4.You will then be prompted to enter your lock screen password, and then click the "Reset All Settings" button at the bottom.

5.After waiting for the restore to be successful, try to re-enter the fingerprint to see if it works.

Hardware failure: If the above methods have been tried and still don't work, it should be a problem with the fingerprint recognition hardware module of the Apple 5S mobile phone. For this kind of hardware failure, the current Apple 5S should still be within the warranty period, and it is recommended to send the phone for repair to the local Apple authorized after-sales service point for testing.

Reboot is a password that requires a password. After that, it's fine.

Reason: First of all, the first one may be that the fingerprint unlock setting is wrong, or some friends don't know how to set it. There was a problem with the operation during the setup process.

The second major reason is that there is a problem with the home button and related parts of the iPhone 5S, which makes this mobile phone unable to scan and read fingerprints correctly.

The third reason is that some users have oily fingers or have sweat and powder on their fingers when setting up their fingerprints, which will lead to errors in fingerprint scanning, which is because iPhone5s is a disadvantage of capacitive fingerprint unlocking. The fourth reason is the user's own fault, the user may have injured his finger, because if there is a scar on the finger, it will also cause the fingerprint to be invisible.

The last common reason is that the user's fingerprint is relatively shallow, which cannot be recorded.

Solution: Find the settings menu in your iPhone5s and tap to open; Find the general option in the settings list and click to enter; Find the "Password & Fingerprint" option in the general list and click to enter; Click on the "Fingerprint" option in the password lock and fingerprint recognition window; Then click on the "Add Fingerprint ID" option; Next, the system will prompt you to put the finger you want to set the fingerprint on the "home screen" button, please touch the home button on the home screen with your finger, and touch it with your finger repeatedly until the system completes its fingerprint record, note that this process should last for one minute, don't put it too fast.

If there is a problem with the home button and related parts of the iphone5s, it is likely that there are stains on the surface of the keys that affect fingerprint entry. If it doesn't work, take it to the manufacturer and ask.

For iPhone5S, the fingerprint unlock setting failed, user reason, users should pay attention before entering fingerprints. 1. Keep your fingers dry when entering fingerprints. 2. Fingerprints are entered on both the left and right hands. Or try typing separately with different fingers.

Reason for fingerprint unlocking failure: There is a problem with the fingerprint input, which causes the fingerprint to be inconsistent with the fingerprint stored in the A7 chip, resulting in unlocking failure.

There are also the following reasons:

1. There is a problem with the home button and related parts of the iPhone5S, and the fingerprint cannot be scanned correctly.

2. Fingers with sweat or powder, or oily fingers. Resulting in an error in scanning the fingerprint, because ipiphone5s allows fingerprint unlocking, there is this drawback.

3. Finger injuries have left scars.

4. The unlocked finger is not the same as the finger you entered before.

5. It may be that the fingerprint is too shallow.

Solution: 1. Keep your fingers dry when entering fingerprints.

2. Fingerprints are entered on both the left and right hands.

3. When unlocking, if your fingers are wet, or there are food crumbs sticking to them, or your fingers are very oily, wipe your fingers dry with a paper towel, which can greatly improve the success rate of fingerprint unlocking.
