Why doesn't Touch ID recognize my finger? A simple and effective way to make Touch ID work better, more securely and faster. Resetting the Scanner

IN Lately V news feed and in in social networks there are often discussions and opinions regarding new feature fingerprint recognition called Touch ID in iPhone 5s. Basically, all discussions come down to security issues and future prospects for this method of protecting and accessing the device. For some reason, what seems to me to be a more pressing question is raised much less frequently: is it convenient to use Touch ID in Everyday life?

It is clear that initially the fingerprint is stored in memory, followed by a touch, then pressing the “Home” button, and as a result, the device is unlocked. All this is very fun and interesting, but does the process really look so beautiful, simple and easy?

I think it would be quite appropriate here to give a few opinions or, if you like, observations from famous people in the world of “Apple-aligned” journalism, based on their personal experience.

For example, here's what John Gruber (of daringfireball.net) has to say about it:

Although, this may be technically correct, Dustin Curtis (creator of the interactive magazine svbtle.com, and part-time blogger) that in fact everything is not quite like that:

When the phone is locked, unlocking with using Touch The ID looks a little clunky; you must touch the sensor on the Home button with your finger, press the button and manage to release it without removing your finger from the sensor, and you must manage to do all this before Siri is activated. It works, but it feels strange.

In general, I will say this - unlocking is truly “instant”, but only if the lock screen is in an active state at that moment. It was funny to watch new owners trying to unlock the device by simply swiping or touching the sensor with their finger. It would seem that a completely simple and logical action - unlocking the iPhone - actually consists of two non-obvious ones: “waking up” by pressing the “Home” button and reading the fingerprint with the sensor. That is, an iPhone in an inactive state simply will not respond to the finger; reading occurs immediately after activating the device by pressing Home as usual.

And John Gruber is at it again:

Touch ID doesn't rely on button presses in any way, and there shouldn't be any delay... Try this: Place your finger on the Home button while your iPhone is locked. Activate iPhone button power button, not the Home button. Unlocking is instant.

What can I say: apparently, I’m somehow wrong, not one of those people who usually unlock the iPhone with both hands...

Touch ID – unique technology fingerprint reading. The following versions are equipped with it mobile gadgets from Apple, like the iPhone 5s, iPhone 6 and iPhone 6 Plus. According to the manufacturer, this technology is more advanced in models of the sixth line. However, many users often complain on forums that Touch ID is a rather poorly functioning element in both the first and second versions.

Touch ID is definitely a good idea. And not only in terms of marketing, but also for practical use. Using Touch ID, the owner of an iPhone can unlock his device, log into the “accounts” of some programs on the network, and make payments using Apple Pay. But this is only if the technology functions smoothly, which is not always the case. Like any electronic mechanism, Touch ID sometimes has problems. How to deal with them? Let's figure it out.

Firstly, if problems were discovered after a recent firmware upgrade to OS version 9 (or more recent ones) iOS versions), may require a downgrade. This term refers to a system rollback to previous version. But if the problems are not so significant, the best solution will wait for the next update.

All other problems are often caused by misunderstandings that do not imply anything serious. Therefore, the user can solve most of them independently, without going to a repair shop. Moreover, there are not many such problems, and the methods for solving them have long been known. In this article we will look at each problem and how to solve it in detail.

It often happens that the fingerprint does not work on the iPhone 6 or iPhone 5S. If a system malfunctions, experts recommend making a simple reconfiguration. In other words, you need to retrain the gadget to recognize a fingerprint. When the first scanners appeared, Apple was concerned about annual updates software for them. This is done so that the devices remember the fingers of their owners as best as possible.

Significant optimization in this area was carried out in the eighth version of the operating system. But as the practical experience of many users has shown, if the fingerprint is not regularly refreshed, somewhere after month touch The ID will start to malfunction. The reasons for this are usually the most banal, but they are basically cosmetic in nature (the fingerprint has worn out, dry skin on the finger, and similar misunderstandings).

Considering the above, if Touch ID glitches on the iPhone 5S you need to update the fingerprint in the gadget’s memory. But before the procedure, you need to thoroughly wipe the surface of the display and wash your hands. Then you should go to the iPhone settings, and after that - to the section Password Touch ID. In this case, the earlier fingerprint must be deleted using a swipe, moving across the display with right side to the left. After this action, you need to click on the add a fingerprint button and again carry out the usual operation of entering a fingerprint, in accordance with the instructions.

Touch ID doesn't work in the App Store

This, like the previous problem described, occurs quite often. And this usually happens due to the fact that the scanner does not interact with App Store. As before, the reason most often lies in cosmetic factors. But sometimes the problem occurs due to software problems in the iPhone 5S. Many users note that gadgets based on OS version 8, or rather, the Touch ID technology in them, do not work in this store.

To solve this problem, you need to follow these steps:

Click on the settings section, and then on the Touch ID and password item.
Go to the technology usage section and disable the App Store.
Reboot the device system.
Come back to initial settings, enable the App Store.

After all the steps have been completed, the Touch ID bug in the store should automatically disappear. Let us also remind you that if the user has not made purchases in a store during the day, when entering the store again, the system will prompt you to enter a password.

The fingerprint scanner doesn't work at all

It happens that the scanner itself fails, that is, it simply breaks. Although this happens extremely rarely.

A breakdown can be signaled by complete inoperability of the technology after the update. In this case, you can try " Hard Reset", having done the backup procedure before this.

But if the issue is a malfunction of the iPhone 5S software, hard reboot usually solves the problem 100%. Otherwise, the user will have to seek repairs, since it is impossible to do without competent diagnostics of the device.

Touch ID stops working in cold temperatures

According to statistics, glitches in the operation of technology in winter or in cold conditions occur much more often. As always, the explanation for this phenomenon is simple. It's all about changes in the papillary pattern of the fingers, which, when changed, weather conditions is changing. Of course, it is not possible to detect such changes by eye. But smart Touch ID immediately detects them and reports failures.

As you might have already guessed, this whole issue is also treated through updating the fingerprint. But here everything can be made even easier. It is enough to complete and save your “winter” fingerprint in the device’s memory. To do this, you need to do the procedure as soon as you come from the street, and your fingers are still cold. Although, this is not a guarantee of a successful solution to the problem. According to reviews from iPhone owners, the above methods do not always cope with the situation.

If the scanner does not work in dirty or damp conditions

There is no need to go into long explanations here. Obviously, moisture and dirt prevent the system from scanning a fingerprint. It's about about the presence of dirt or moisture not only on the finger itself, but also on the surface of the scanner. Therefore, before the operation, you need to wash and dry your hands well and carefully wipe the scanner with a dry cloth.

But one thing to remember important point: There is no need to keep your hands in water for a long time when washing, as this will cause the skin to swell and the papillary pattern will change significantly.

However, Apple guarantees fans of its products that in the new sixth line of gadgets labeled S, Touch ID works more effectively with wet surfaces. But at the same time, the developers still do not recommend using the scanner when your hands are wet.

Breakdowns after repair: reasons

Speaking in simple words, during the process of repairing the device, the cable between Touch ID and the telephone board may be damaged. This leads to the fact that the system is no longer able to determine the authenticity of the fingerprint. And after that, the gadget deactivates the biometric sensor. IN similar situation Replacing individual elements in order to improve the operation of the technology is impossible. Identifiers between Secure Enclave and sensor third party manufacturer they just won't match.

If the cable is completely damaged, then restoring it is an impossible task. The fact is that it includes ten tracks consisting of several layers. And the thickness of each track is a tenth of a millimeter.

A different situation with the elements Home buttons regulating the click registration process. Replacement is a simple matter. However, from now on, unlocking the device will be available exclusively through a password. It's easy to identify a broken Touch ID through settings. To do this, you need to carefully consider the menu for adding new fingerprints. It must be gray if there are any malfunctions.

The only method of obtaining a properly functioning sensor with fingerprint technology at its core is to use elements of another device. This means that you will need to install new board and the Home button. However, this repair will be very expensive for the user. In such a situation, it is advisable to purchase new iPhone. Of course, if Touch ID technology is very important for the user.

Touch ID is an excellent technology developed by Apple, which allows you to increase the security of user data on the company's devices. To the Home button on iPhone and iPad Apple company has a built-in fingerprint scanner that allows you to identify real user devices without having to enter a password. In this case, identification is used not only to unlock the device, but also when logging into various applications, paying for purchases in online stores and in a host of other situations.

But no technology is perfect, including Touch ID. Users may encounter another attempt using the fingerprint scanner with an error “Crash. Touch ID setup cannot be completed. Go back and try again". On English language this error sounds like this: "Failed." Unable to complete Touch ID setup". Faced with similar problem, it will take some effort to fix it, and in this article we will look at the main ways to do this.

Updating fingerprints in Touch ID

Quite often, the error “Cannot complete Touch ID setup” occurs after updating your device. Apple regularly releases new firmware versions for iPhone and iPad, but their installation does not always go without errors and problems. If you have a problem with downloading and installing a new version of the software Touch operation ID, try the following:

After completing all the steps described above, the “Unable to complete Touch ID setup” error should no longer bother you.

What to do if updating your fingerprints doesn't help?

If you followed the instructions described above, but did not succeed in getting rid of the problem in question, there are a few more tips on how to fix the error:

If none of the above methods helped fix the situation, you can try to wait until Apple releases new version firmware and install it, it is possible that this will fix the problem. Another way is this.

It is worth noting that if you contact the official service center Apple, you can hear the answer that this malfunction is hardware. If the phone is under warranty, Apple will repair the device free of charge (replace the Home button) or exchange it for a new one. That is why it is not recommended to try to disassemble the device yourself and try to “fix the Home button cable”, which is what various “craftsmen” recommend doing when the error “Cannot complete Touch ID setup” occurs.

iPhone and iPad can be considered premium devices. However, users also have problems with them. One of these common problems is “Crash. Touch ID setup cannot be completed." This error occurs when updating operating system and disappears with the subsequent loading of components. For those who don't want to wait next update, we suggest the following methods to solve the problem.

Ways to solve errors when setting up Touch ID

The official way to solve the problem is to recreate Touch fingerprints ID. The instructions for performing it are as follows.

Select the “Settings” menu, then “Touch ID and passcode”.

A new window will appear. Here we enter the password, and also disable “ Unlocking iPhone" And " iTunes Store And Apple Store" On some models, this section may have an “Apple Pay” item. It also needs to be disabled.

Let's go back to home screen. Press and hold the Home and Power buttons AT THE SAME TIME. We hold these buttons until the Apple logo appears. The device will reboot. This may take some time.

After rebooting the device, you should go back to “Settings”, “Touch ID and passcode”. Here we enable those items that we disabled earlier and set a new fingerprint. Everything should work. However, if this method does not work, you should try the following.

Go to “Settings”, “General”, “Reset” and click “Reset all settings”.

Then we try again to create a fingerprint.

If resetting the settings does not help solve the problem, you should contact the service Apple support. According to reviews from many users who encountered a similar problem, replacing the Home button and sensor helped. However, you'll be lucky if your phone is under warranty. This service is quite expensive.

What password can be called the most reliable and at the same time constantly accessible to the owner of the equipment? Fingerprint. IN new development Touch ID uses a fingerprint sensor as a means of identification. This method allows you to quickly or otherwise Apple devices and at the same time be confident in the security of the stored data.

Of course, the question immediately arises: Touch ID - what is it? The device itself, the technology or, in general, the phone model? Apple Touch ID is a technology that involves the use of a sensor that recognizes the user's unique fingerprint pattern. The unlocking process is simple: just place your finger on the Home button. The installed sensor reads the received data from absolutely any angle and in any way the iPad is positioned.

button iPad unlock mini 3 is made of sapphire crystal, which is enclosed in a stainless steel ring. Each part: the ring detects touch, and the glass part transmits fingerprint data to the sensor. The reading program carries out comparative analysis and signals compliance. It is noteworthy that the Touch ID sensor performs the entire operation within a fraction of a second.

Advantages of the technology:

Speed of response and minimum number of required operations.
Safety confidential information(due to the specific architecture of the A7 processor).
Information Security user (the password and fingerprint used cannot be copied or transferred in any way, and is also not available to the OS and applications).
Authorization in applications (Touch ID technology is already integrated to simplify the process of confirming actions or signing).
Using your fingerprint, you can confirm your purchase and iTunes - use Touch technology ID will eliminate the need to enter payment data and passwords.

How to enable and configure Touch ID?

Unfortunately, it is not yet possible to put a single checkmark to implement the functions of the technology. Then a logical question arises: how to enable Touch ID?

Initial setup

First of all, you should deal with the initial setup. She :

Before starting the process, thoroughly wipe the button and fingers.
Enter a four-digit password that you have created, which the program will use without recognizing the fingerprint (the request is also possible after a reboot, two days after the last unlocking of the device, or to access functions).
Holding the device as if you normally press “Home”, place your finger on the button (a light touch is enough) and hold it until there is a slight vibration or until the system signals that you can remove your finger.
After completing the initial recognition, the system asks you to change the position of the pad - this is necessary to complete the scanning. Now you need to attach the edges of the fingertip.

If the device is activated, then initial setup can be done through the main menu: by going to “Settings”, select “Touch ID and password”, then “Fingerprints”. The system itself will offer to go through the described registration process and about fingerprints.

Activation methods

If you can't set up Touch ID, you can use the sensor for purchases and password entry. To unlock an iPhone using technology, simply wake it up from sleep mode by pressing the “Power” or “Home” buttons, and then place your finger on the “Home” button. To use a sensor as an identifier account, you need to go to the settings section, then select “Touch ID and password” and activate “iTunes Store, App Store”. When downloading content, the system will inform you that you need a fingerprint on your iPad or other device.

Authorization using a scanner is activated separately, in the settings. Below are the relevant actions for Touch activation ID on iPhone 5s, iPhone 6 Plus with iOS 8 and updated iPhone 6 free application 1Password:

Open “Settings” (tab located on the bottom panel of the program).
Select the “Security” section.
Scroll to the tab with the name of the technology.
Switch the toggle switch to the “On” position.

Now the entrance to the program is available after pressing the fingertip against the sensor for a second!

Non-working function: defective or improper operation?

Undoubtedly, but what should you do if Touch ID stops working or does not work initially? There may be several reasons for this:

Household reasons (incomplete coverage of the button with a fingertip, contamination of the sensor, and even others). It should be noted that most of the complaints about Touch ID not working well fall precisely under this and the next category.
Just a glitch in the recognition program. In this case, it is better to register a different fingerprint.
There is, unfortunately, such an option as marriage. An indicator of such a situation is the lack of effect from rebooting the device and a scanning error. Moreover, it does not matter whether the defect was made at the production stage or by a rogue seller who assembled one iPhone from two without taking into account the linking touch sensor ID to “its” processor, the phone will still have to be taken to a service center.

With customization of the functionality, the functions in each application are more than covered by convenience, speed of operation and optimization of purchasing processes. Although the possibility of a marriage that could bring trouble cannot be ruled out.
