What s the deal with the insensitive fingerprint when the Apple 7 plus is charging?

1. There is an error in the home button and finger fingerprint sensing, such as a hand with water, which cannot be recognized, it is recommended that you add multiple fingerprints to unlock it, and try to change the fingerprint.

2. It may be that your charger is not original and the voltage is unstable, so it is recommended to try to replace it with an original charger.

3. The fingerprint does not fully touch the metal ring, resulting in an error in identification. It is recommended that you place your finger multiple times to increase the recognition rate.

How to set a fingerprint passcode:

1.Click Settings - General - Password & Fingerprint.

2.Click to open the password (if you have already set your fingerprint during the activation process, you can skip this step and add your fingerprint directly, and you can register up to 5 fingerprints).

3.Select Add Fingerprint.

4.To start setting up your fingerprint, place your finger on the home button and follow the prompts.

5.It takes several times to complete the setup of fingerprint addition, you need to repeat the action according to the prompts, then lift your finger after placement, and then place the repeat action.

<>6.Until it is successful, you can unlock your iPhone with your fingerprint

1. The sensor becomes dirty: The TouchID sensor is recognized by the static electricity and heat of the finger: when entering, it is not easy to identify if the fingerprint of a finger is not obvious.

2. If the home button becomes dirty, because when you use one hand to unlock the phone, instead of hanging on the home button**, the metal ring next to it is also one of the components that increase the recognition rate, you need to place your fingers many times, you had better enter a few more, or restart the device, so if it is a broken limb, it cannot be used; The second is to adjust the input of different positions.

3. The colder environment will also affect the working of the sensor.

1. For the problem of mobile phone film, try to contact the fuselage directly with your hands.

2. If there is a problem with the charger, you can change the charger and try it.

3. The fingers or mobile phone are damp and the ambient temperature is too low. The Touch ID sensor uses static electricity and heat from your finger to identify it, so if your finger or home button gets water stains or is too wet, it will also cause recognition to fail.

4. Restart your phone. For security reasons, fingerprint unlocking cannot be done every time the phone is restarted, and you need to use a passcode to unlock it before you can use the Touch ID function again.

5. The sensor is stained. If the home button is stained, it also has a great impact on fingerprint recognition, of course, we can't guarantee that the finger is in a very clean state at all times, at this time you only need to wipe the home button with a clean cloth.

6. It may be a voltage problem, and there is also a quality problem of the plug-in board.

7. It may be a problem with the mobile phone system.

Workaround:

1. It is recommended to change a data cable or socket to try to charge it again.

2. If the unlocking is still not sensitive after replacement, it may be a system failure, just restore all settings.

3. If these cannot be solved, it is recommended to send it for repair to the Apple authorized after-sales center for testing.

Here's how to solve the problem:

1. After the Apple mobile phone is permanent, the fingerprint recognition is often not sensitive, which may be a problem with the fingerprint setting, and under normal circumstances, the fingerprint needs to be re-entered once after 2 or 3 months.

On the main page of your phone, go to the Settings option.

2. Select [Touch ID & Passcode] settings.

3. After entering [Touch ID & Password], delete the previously entered fingerprint, and click [Add Fingerprint].

4. In the process of entering fingerprints, make sure that there are no stains on the home button, you can use a paper towel to wipe it, and there can be no stains on your hands, which are all ways to improve fingerprint recognition.

5. After successful entry, touch the entered fingerprint directly on the home button, and a black stripe will appear, indicating that the fingerprint is successfully entered and valid.

Method 21: If you have re-entered your fingerprint and it still fails, you can wipe the home button before unlocking, which can improve the accuracy of your fingerprint.

2. Whether the fingers are watery, sweaty, stained, peeling, etc. If there is water, sweating, stains, and peeling fingers, it will affect the success rate of fingerprint entry.

It is recommended to reset the fingerprint unlock and then clean the keys and hands.

The fingerprint recognition does not work when charging, because the charging provides unstable or excessively high current and voltage, and this may also cause the finger to be charged when it touches the idtouch.

2.I tried to plug it into the computer with the original data cable before, but it can't be unlocked, but it can be plugged into the original charging head, which is further proof.

3.Therefore, when charging the iPhone, you should use the original accessories or accessories of third-party brands certified by Apple MFI.

4.The third-party brands with Apple MFI certification are: iwalk, belkin, etc. The same is true for other mobile phones or electronic products except for iPhone, which should be used with original equipment or recognized by the original manufacturer.

iPhone7 Plus is in Settings - TouchID & Passcode - Add Fingerprint.

The charging head and data cable are the direct cause.

What is the reason why the touch screen of the iPhone is not sensitive?

Inferior tempered film has a certain impact, at present, I have used it for half a year, and there is nothing wrong.

It's been a long time, change the screen, domestic 200, original 700

iphone7plus fingerprint unlock does not work solution:

1.Adjust the position.

When entering, not only do you need to place your fingers vertically, but you also need to adjust the angle appropriately, and you can adjust the angle of your fingers at willUse different fingers.

Touch ID can enter the fingerprints of up to 5 fingers, if the fingerprints of a finger are not obvious and not easy to identify, you had better enter a few more to increase the recognition rate, 3Make sure your fingers are touching the metal ring.

The sensor of Touch ID is composed of many parts, among which the metal ring is one of the most important components to increase the recognition rate, so when using it, make sure that your fingers touch the metal ring, rather than hanging on the home button**, after the fingerprint is recorded, when we usually use the mobile phone, due to some of the following reasons, fingerprint recognition will also fail.

Hope it helps.

As follows:1Wet fingers or mobile phones, and the ambient temperature is too low.

The Touch ID sensor is recognized by the static electricity and heat of the finger, so if your finger or home button is stained with water or too wet, it will also cause recognition failure, then make sure that the finger and the phone are dry, in addition, the cold environment will also affect the work of the sensor;

2.The phone restarts.

For security reasons, fingerprint unlocking cannot be done every time the phone is restarted, and you need to use a passcode to unlock it before you can use the Touch ID function again.

3.There is a stain on the sensor.

If the home button is stained, it also has a great impact on fingerprint recognition, of course, we can't guarantee that the fingers are in a very clean state at all times, at this time you only need to wipe the home button with a clean cloth, and the general fingerprint recognition will immediately "resurrect with full blood".

Hope it helps.
