The fingerprint sensor on the phone is not working. What to do if your iPhone's Touch ID sensor is broken

Youtube

Touch ID is a device for recognizing fingerprints of iPhone and iPad users. Thanks to reading, you can unlock your phone or instantly log in to applications such as Amazon, LastPass. The function is also used in the AppStore to make payments.

After installing the new iOS 10, some users experienced problems with the scanner. There are several types of malfunction:

The phone freezes at the fingerprint recognition stage;
Sensor not working while charging iPhone;
Sudden reset of previously configured fingerprints.

Also, the reason that Touch ID does not work on the iPhone may be a fall or impact of the phone, which damages the sensor. Let's take a closer look at how to quickly solve the problem and return the fingerprint scanner to normal.

Resetting the Scanner

If your iPhone freezes while scanning your fingerprint, you should reconfigure the sensor. All data about saved “fingers” is located in the phone settings (the “Touch ID and password” window).

Delete all existing fingerprints, turn off the sliders " Unlocking iPhone" And " ITunes Store, App Store" and then restart your phone. After turning on your device, go to settings again and add new multi-fingerprints. This re-configuration allows you to reset the erroneous configuration and resume operation of the scanner at the software level.

No Touch ID response while charging

There are cases when Touch ID does not work while charging the iPhone. In this case, you should completely discharge the phone, then connect it to power and charge it to 100%. During charging, it is advisable to turn on Airplane mode and not use the device. Then do a soft reset (without data loss). After these steps, the biometric scanner will work normally. Do not use a fake iPhone charger; after connecting it to the device, functional failures may occur.

Remember! You should not update your phone's firmware or restore it through iTunes if one of its hardware components does not work (Touch ID, camera, etc.). During the update process, the desktop program automatically checks the functionality of all components of the smartphone. If contact with one of the components is not established, error code 53 will appear (the update progress will be canceled, and because of this the iPhone will no longer turn on).

Improving sensor performance in cold weather

In the cold, fingerprints are less recognized, and the phone’s biometrics often fail. To improve Touch ID performance in cold temperatures, enter a new cold fingerprint into the existing scanner database. This helps the iPhone remember the current state of the finger and better recognize it in the future.

Replacing the Touch ID cable

If the cause of a non-working scanner is a hardware failure, previously saved data will not be displayed in the smartphone settings (Touch ID window). There will also be no option to add a new fingerprint. The only solution is to check the scanner cable.

Disassemble the phone and remove it from display module Home button. Check the connection of the cable, if it just came off, just reconnect it and reassemble the phone. However, it will most likely be torn. The figure below shows clear example a break in the Home button cable (the location of the breakdown is indicated by a red curved line).

There is no way to replace the cable, because the Home button cannot be disassembled. In this way, Apple protects devices from biometric sensor substitution. The Home button should be replaced (when purchasing the part, a corresponding cable is included in the package).

Any instructions for self-repair You can find your iPhone on our website, or call a specialist for to any place convenient for you.

Is the Touch ID sensor on your iPhone or iPad not working as well as it used to? Are you able to unlock your device only after several attempts? It may be a hardware issue, or the problem may not be that serious and can be easily fixed.

Your device's Home button below iOS control- extremely sensitive equipment. Not only does it allow you to instantly switch to home screen, but also plays the role of a powerful fingerprint scanner. Any iPhone user will confirm that when it works (and, more often than not, no problems arise), everything is just fine. However, sometimes this button does not function quite correctly.

If your Touch ID sensor has started acting strange, there could be many reasons for it. But before you replace it entirely, try a few solutions that may help you save money.

Note: If you still need to change Hardware, remember that this can only be done by Apple itself or an Apple-authorized repair technician. Replacing the Home button at a third-party repair shop can lead to serious problems.

Mud and water

Most often, dirt and water are the culprits of the problem. Most likely, you will not be able to unlock the device with wet or damp hands.

Likewise, if your hands are covered in a layer of dirt or grease that obscures fingerprints, gaining access to your device may not be such an easy task.

IN in this case The solution is quite simple: wash your hands and dry them.

However, there is a possibility that dirt may have gotten on the Home button itself. Try wiping it with a soft, dry cloth. If this doesn't help, use a can of compressed air.

Cold weather, hard work and worn fingerprints

Cold weather can dry out your hands, leaving them rough. If you live in a cold, dry climate, there's a good chance that your fingerprints will change enough that Touch ID won't recognize them.

Handwork can also affect your fingerprints. Your hands may become so rough and worn that Touch ID has trouble recognizing your fingerprints.

Try adding the altered fingerprints to the list of acceptable ones until the weather changes or take a break from working to return your hands to their previous state.

Issues with updates

You should always install the latest updates for your iOS versions, by the way, I recently wrote about how to disable Predictive dialing, . However, sometimes new software versions can become a source of problems. If you experience sudden Touch ID sensor failure right after updating your iPhone or iPad, it may be due to faulty software.

In such a situation, you can wait to install the update, or roll back the system to previous version software.

Update the fingerprints stored in the system

If none of the above methods helped you, try updating your fingerprints saved in the system. This procedure will likely resolve many, if not all, Touch ID related issues.

We have several articles dedicated to this process. There is a method to improve fingerprint recognition on your device. In addition, you can add additional prints in case the main ones stop working.

When all else fails, use a factory reset

If even updating your saved fingerprints does not help you, you may have to reset device to factory settings. After contacting the workshop, this is the most extreme option, which will lead to complete cleaning your iPhone or iPad. Therefore, if you do not want to lose your photos, videos, messages and other important data, take care of it in advance.

If you still can't solve the problem, it's time to admit defeat and take your device to certified technicians for repair. It won't be cheap, but the Home button is tightly coupled to your iPhone or iPad, so you don't have much of a choice. If you try to save, you'll probably end up spending more money in the long run, and also risk turning your device into a piece of plastic. Contact Apple and Apple-authorized repair shops only.

Of course, such protection was to the taste of users who immediately began to use all the benefits of “Apple products”. However, after some time on the site official technical support Apple began to receive numerous complaints about the fact that it could not complete touch setting ID. This useful solution turned out to be completely ineffective? Or can the problem be solved? Let's take a closer look in the article.

Causes

There are many factors that can affect the performance of a smartphone. Some people attribute the failure to complete Touch ID setup to updated design standard applications, new Siri features, changing the CarPlay interface and much more. However, the reasons may be much more trivial than it seems at first glance.

Most often, problems with the scanner appear at subzero temperatures. In this case, the Touch ID setup cannot be carried out due to the fact that the touchscreen is simply frozen and cannot recognize the user. In addition, in cold weather it also changes on a person’s fingers. Of course, this cannot be seen with the naked eye, but for sensitive equipment this is a huge problem. Therefore, if you were unable to complete the Touch ID setup, return to a warm place and try to repeat the procedure again when the device and your hands are warm.

The second common reason is dirt and moisture. If you try to set up the scanner in the rain or in cloudy weather, when high humidity prevails outside, then most likely nothing will work. The same goes for dirty hands. Again, your fingers may look clean on the outside, but this will not be enough for the scanner.

Of course, there are more serious reasons why Touch ID setup couldn't be completed. Quite often the problem occurs due to incorrect setting or a short program crash. The reason may also lie in the hardware.

Correct setting

In order for Touch ID to work fully, you need to configure it. To do this correctly, you need to follow these steps:

Make sure the Home button is clean and free of moisture. Hands must be dry.
Go to your phone settings and select “Touch ID password”. Enter the code combination.
Click “Add fingerprint” and calmly touch the Home button without pressing it too hard.
Hold your finger still until the device begins to vibrate.
Repeat the procedure. The finger must be lifted several times and pressed against the button again. It is recommended to change its position slightly.
A new menu will appear on the screen where you will be asked to adjust the fingerprint capture. To do this, you need to take the phone in your hand the most in a convenient way and place your fingertip on the Home button. This procedure is also repeated several times.

If you still can't complete the Touch ID setup, you can try using another finger. Or use another method.

Restoring Touch ID

To roll back previous changes and set new parameters, you must complete the following steps:

Go to the main menu and select “Touch ID password” again.
Enter the access code and delete old biometric data.
Repeat the procedure for adding a “cast”.

If after this you still cannot complete the Touch ID setup on your iPhone, you can try restoring the system through a backup that was previously made in cloud storage or on PC. To do this, you need to connect your device to your computer and go to iTunes. Next, you just need to click the “Restore” button and select the desired backup date. After recovery, you must re-enter your biometric data as described earlier.

If the problem is hardware

If it didn't happen software glitch and you cannot complete the Touch ID setup, the reason may lie in the device itself. The Home button cable may have come loose. To solve this problem, you need to carefully disassemble the phone. Then you need to disconnect the cable from the button, check if there is any damage on it, and re-insert it. In some situations, this helps fix the error.

However, such experiments should not be carried out without proper experience. If the user is confident in his abilities, then before performing such operations it is necessary to save all data from the smartphone.

If Touch ID stops working in the App Store

Very often, users notice a problem with the scanner only when logging into official store Apple. However, if the fingerprint is not removed in the App Store, this may also indicate a problem with the device.

In this case, you must perform the following steps:

Go to settings and go to “Touch ID password”.
Enter the code and find the “Usage” section.
Disable the App Store and iTunes Store in it.
Reboot the device.
Go to the settings again and repeat the procedure, only this time the stores must, on the contrary, be activated.

This usually helps get rid of bugs.

Technical support

If none of the above helped, do not despair. Experienced specialists Apple support can help you figure out why you can't complete Touch ID setup. To do this, you need to go to the company’s official website and create the appropriate ticket. Or you can search in already questions asked. Most likely the website has a large number of discussion threads with similar problems. If the consultants suggest doing everything that has already been stated, then all that remains is to go to the service center and try to diagnose the device. Before doing this, you should copy all the data from the phone again.
