Starting with the iPhone 5 and iPod 4, fingerprint scanners appeared on the devices . 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, numerous complaints began to appear on the official Apple tech support site that Touch ID could not be completed. Was such a useful solution completely inactive? Or can the problem be solved? Let's consider in more detail in the article.
Causes
There are many factors that can affect the operation of a smartphone. Some associate the fact that it was not possible to complete the Touch ID setup with an updated design of standard applications, new Siri features, a change in the CarPlay interface and much more. However, the reasons may be far more trivial than it seems at first glance.
Most often, problems with the scanner appear at low temperatures. In this case, the Touch ID setting cannot be performed due to the fact that the touchscreen is elementarily frozen and cannot read user biometric data . In addition, in cold weather, the papillary pattern on the fingers of a person changes. Of course, with the naked eye it is impossible to see, but for sensitive technology this is a huge problem. Therefore, if you could not 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 cause is dirt and moisture. If you try to set up the scanner in the rain or in cloudy weather, when high humidity prevails on the street, then most likely nothing will work. The same goes for dirty hands. Again, outwardly the fingers may look clean, but this will not be enough for the scanner.
Of course, there are more serious reasons that the Touch ID setup could not be completed. Quite often, the problem arises due to incorrect settings or a short program crash. Also, the reason may lie in the hardware.
Correct setting
In order for Touch ID to work fully, you need to configure it. To do this correctly, you must complete the following steps:
- Make sure the Home button is clean and free of moisture. Keep your hands dry.
- Go to your phone’s settings and select “Touch ID password”. Enter the code combination.
- Press “Add fingerprint” and calmly touch the “Home” button, without pressing it too hard.
- Keep your finger stationary until the device vibrates.
- Repeat the procedure. The finger needs to be lifted several times and pressed again to the button. It is recommended to slightly change its position.
- A new menu will appear on the screen, where you will be asked to adjust the capture of the fingerprint. To do this, you need to take the phone in your hand in the most convenient way and apply a small pillow of the finger to the "Home" button. This procedure is also repeated several times.
If you still could not complete the Touch ID setup, then you can try to attach the other finger. Or use a different method.
Touch ID Recovery
To roll back previous changes and set new parameters, you must perform the following steps:
- Go to the main menu and select “Touch ID Password” again.
- Enter the access code and delete the old biometric data.
- Repeat the process of adding a "mold".
If after this you still cannot complete the Touch ID setup on the iPhone, you can try to restore the system through a backup that was previously done in cloud storage or on a PC. To do this, connect the device to the computer and go to iTunes. Next, just click the “Restore” button and select the desired backup date. After recovery, biometric data must be re-entered as previously described.
If the problem is hardware
If there was a non-software failure and you cannot complete the Touch ID setup, then the reason may lie in the device itself. Perhaps the loop of the Home button has departed. To solve this problem, you need to carefully disassemble the phone. Then it is necessary to disconnect the loop from the button, clarify whether there is damage on it, and re-insert it. In some situations, this helps to correct the error.
However, without proper experience, such experiments are not worth it. If the user is confident in their abilities, then before performing such operations, it is necessary to save all the data from the smartphone.
If Touch ID stops working on the App Store
Very often, users notice a problem with the scanner only when they enter the official Apple store. However, if the fingerprint is not removed in the App Store, this may also indicate a malfunction of the device.
In this case, you must perform the following steps:
- Go to settings and go to the “Touch ID password”.
- Enter the code and find the "Usage" section.
- Disable in it the App Store and iTunes Store.
- Reboot device.
- Go back to the settings and repeat the procedure, only this time the shops need, on the contrary, to activate.
This usually helps to get rid of bugs.
Tech support
If none of the above helps, do not despair. Experienced Apple tech support experts can help you figure out why Touch ID setup isn't complete. To do this, go to the company's official website and create an appropriate ticket. Or you can search in already asked questions. Most likely, the site has a large number of discussion threads with similar problems. If the consultants offer to carry out everything that has already been voiced, then it remains only to go to the service center and try to diagnose the device. Before that, you should once again copy all the data from the phone.
