Why does not work with a touch ID on iPhone. Touch ID: Just you toucher incorrectly

Sometimes there is a problem at which the fingerprint does not work on smartphones Xiaomi Redmi. 4x and other models. The reason for this can be technical or software malfunctions. Each of these reasons includes several aspects. In this article, you can find answers to all issues related to the inoperability of the print scanner.

Fingerprint scanner works on a simple principle. Special sensor recognizes patterns on the pads of the fingers. These lines are unique for each person. Photo cells, after the finger applied close to the scanner platform, photographs those patterns of the pattern on a finger pad that do not touch the site. That is, the scanner does not read those lines that protrude above the skin, but those that are located between them.

Some of the fastest scanners are installed in Xiami. Unfortunately, they are far from the most efficient. They may not identify the imprint in the event that the owner's hands are wet, sweat or dirty. If there will be even a minimum amount of fatty divorce, the scanner will refuse to identify.

Therefore, if the sensor refuses to read the pattern, it must be wiped and conducting hand hygiene. If earned - it means everything is in order. If not, then the reason or hardware or software.

Solving problems with the work of the scanner

Sometimes the scanner does not work because of the incorrect photographing of the imprint. In other words, the recording of the pattern was not carried out at different angles (for a clearer film recognition) or was interrupted, and the imprint was not fully inflicted.

To overwrite the entered data you need:

IMPORTANT: Applying pillows you need at different angle so that in the future you can make a finger as you like, and the smartphone still unmistakably identified it and allowed access.

Overwriting prints will make it clear why the print scanner does not work. However, the reason may be hidden in the other. Often, after updating the software, the smartphone begins to bite the sensor. Here you can fix the situation to the factory settings. For this you need:

ATTENTION: All data from the smartphone will be deleted! They must be copied to other devices. SD card must be removed before the procedure!

Another way is simple operation Complete smartphone discharge. It must be completely discharged to 0% so that it turns off. At the same time, it is desirable to leave it in this state for 12 hours. You will need to turn on the device into the outlet and charge it up to 100% not including! When it charges, you need to turn on the phone without removing from charging. After a certain time (or immediately), the smartphone will offer to use a scanner for identification. Thus, the failure will not be repeated anymore.

What to do if the imprint is not added

There are situations when the scanner works, but the fingerprint fails to re-finish. To reset through the addition of new data fails. So, when trying to create a new pattern, many owners of Xiaomi appears the error "Repeat an attempt", or "Failed to add a fingerprint".

You can try to correct this situation as follows:

This method can help, but not always. If the print scanner refuses to adjust the pattern, then go to the radical measurement - to reset the settings to the factory.

We solve problems with the removal of the print

Among frequent questions Meets: I can not remove the imprint what to do? The answer is the next question - you need to change the language of the system. For this you need:

After that, it will be necessary to conduct a fingerprint procedure. After a successful operation, the language settings can again be switched to "Russian".

If the solution does not help, then you will have to reset to factory settings. In the case when the print scanner issues some faults, you can make a flashing phone that is much more complicated. This method It is not recommended for the use of those people who do not have at least basic knowledge to reinstall operating system in phone. Otherwise, you can simply spoil the smartphone.

Conclusion

It is worth saying that Smartphones Siaomi rarely when they give such bugs. If they arise, they quickly eliminate them in the company. In the case when the scanner stopped working, then it is not necessary to reset the settings. This will lead to the loss of all data (if they are not previously copied to other devices or media). It is enough just to wait for the correction of the bugs of the MIUI shell. Usually fixed versions become newly available for upgrades no later than a week. Therefore, it makes sense to wait for the released OS to establish it again.

Installing Xiaomi fingerprint scanners to its models has become more common than the symbol of the elite device. Fingerprint at Xiaomi Redmi 3s became one of the first swallows that promoted this technology "to the people".

Already now boast the presence of a high-precision scanner can most of the new Siaomi Tablet. For example, slightly enlarged in the sizes of Xiaomi Redmi Note. 4 or even "half-male" Xiaomi Mi Max. The newest representative of the sixth line Xiaomi Mi6 inherited and received an improved sensor hidden under the glass on the front side of the phone.

In some budget models, like Xiaomi Redmi 4a, a similar sensor is not provided at all, while enough fresh Xiaomi Mi 5, it often works with interruptions and can disappear completely.

Consider the algorithm for adding a new fingerprint.

How to turn it on

Setting the fingerprint to Xiaomi for the first time happens as follows:

1. Go to the "Settings" menu and select the "System" and fingerprint screen "in the" System "list;
2. Next, click on the "Screen Lock and Fingerprint". In Novom open menu pay attention to the lowest point in the window - "add a fingerprint";
3. The system proposes to specify a graphic key in case the imprint on the scanner does not work or the device will partially fail;
4. We repeatedly apply any finger (one and the same) to the surface of the scanner of your smartphone. On the success of each stage of the scan, you will report animation with a filling of a mug and light vibration of the device.
5. If everything is done correctly - you receive a notice of successful configuration. Your device is ready. Additionally, you can install and select another print.

About how it is more convenient to make scan, we will be prompted by the location of the sensors. For example, in the Xiaomi MI 5S, the sensor has a rear position (default for index finger), and in MI 6 - front (for thumb).

However, everything is not always happening so smoothly. It happens that in certain models, as in Redmi 4x, in the settings there is no print menu or the phone does not respond to touch.

Possible problems

Smartphones Xiaomi, as well as samples from other manufacturers, are not perfect. Some of them are subject to systematically emerging problems (namely: the imprint does not work xiaomi fingers) Many users.

Glitters can be several:

• fingerprint scanner works with interruptions;
• disappeared sample;
• there is no reaction to pressing the sensor field;
• the corresponding point in the tincture menu disappeared.

To self-eliminate these unpleasant phenomena in the smartphone, you need to make such actions:

1. unlock it graphic key the main screen installed when setting up;
2. fully discharge the device before automatic shutdown;
3. charge the battery to 100%;
4. wipe the touchscreen sensor with a dry clean cloth;
5. start your smartphone (the sensor should earn).

Often tactile recognition ceases to work on Xiaomi Mi 5, which is explained by the shortcomings official firmware. If the phone does not find it or the menu disappears, as if it was not - you need to contact service center Siaomi. There, your phone will conduct a detailed analysis of the fault that has arisen, and, if necessary, repair or replace the part.

Nuances

Not in all cases of Xiaomi CO, the fingerprint scanner should be supplied to the repair or "torment" firmware itself. New budget and flagship models of smartphones at the start have "raw" firmware. Developers simply do not have time to eliminate all its flaws. Most often, the solution of such trouble becomes a new update. Thus, the work of the fingerprint scanner on the MI 5S was fixed.

The banal cause of the interpretation of the lock screen of the lock can be melted or wet finger. Cuts and scars also negatively affect the ability of Xiaomi to block the screen.

Sometimes the problem is allowed by switching the language into English, followed by the removal of a poorly recognized old scan sample, and replacing it with a new one.

Extreme option - Disable non-working scanner on the phone.

Remove fingerprint

For Linek phones Siaomi and Redmed, creating a new sample scan, occurs exactly as a disconnection of the old one.

The removal process takes less than a minute:

1. we enter the menu "Lock screen and fingerprint" (the path to it is specified in the second section of the article) and enter the password.
2. by clicking on the "New Password" point, confirm the removal of the scan on the smartphone.

After disconnecting the sensor, it will not respond to the touch until the master does not want to set a new profile.

Of course, such defense accounted for 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 Numerous complaints began to appear that it was not possible to complete the Touch ID setup. That useful solution It turned out absolutely inactive? Or can I solve the problem? Consider more in the article.

The reasons

There are a lot of factors that can affect the work of a smartphone. Some bind what failed to complete the configuration of the Touch ID, with the updated design standard applications, new SIRI features, changing the CarPlay interface and many others. However, the reasons may be as trivial than it seems at first glance.

Most often, the problems with the scanner appear at negative temperatures. In this case, the Touch ID configuration cannot be carried out due to the fact that the touchscreen is elementary frozen and cannot count the user. In addition, it changes in cold weather on the fingers of man. Of course, it is impossible to see the naked eye, but for sensitive technology it is a huge problem. Therefore, if you failed to complete the Touch ID setting, go back to a warm place and try to repeat the procedure again when the device and your hands get warm.

The second common cause is dirt and moisture. If you try to adjust the scanner in the rain or in cloudy weather, when the increased humidity prevails on the street, then, most likely nothing will happen. The same applies to dirty hands. Again, outwardly fingers may look clean, however, it will not be enough for the scanner.

Of course, there are more serious reasons for the fact that it was not possible to complete the configuration of the Touch ID. Quite often the problem arises from incorrect setting or short program failure. Also, the reason can be wounded in the hardware.

Proper setting

In order for the Touch ID fully worked, you need to configure it. To make it right, you must perform the following steps:

• Make sure that the "Home" button is clean, there is no moisture on it. Hands should be dry.
• Enter the phone settings and select the Touch ID password. Enter a code combination.
• Click "Add a print" and calmly touch the "Home" button, without pressing it too much.
• Hold your finger in a stationary state while the device does not begin to vibrate.
• Repeat the procedure. The finger needs to lift several times and press the button again. At the same time it is recommended to change its position slightly.
• A new menu will appear on the screen, where it will be prompted to adjust the capture of the imprint. To do this, you need to take the phone in the hand most in a convenient way And apply a finger pad to the "Home" button. This procedure is also repeated several times.

If you still failed to complete the Touch ID setting, you can try to attach another finger. Or use another method.

Restoring Touch ID

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

• Enter the main menu and select the Touch ID password again.
• Enter access code and delete old biometric data.
• Repeat the procedure for adding "cast".

If after that still fails to complete the Touch ID setting on the iPhone, you can try to restore the system through backupwhich was previously done in cloud storage or on PC. To do this, connect the device to the computer and go to iTunes. Then it is enough just to click the "Restore" button and select the desired backup date. After recovery, biometric data must be re-made, as described earlier.

If the problem is hardware

If not happened software failure And it is not possible to complete the configuration of the Touch ID, then the reason may wage in the device itself. Perhaps the loop of the HOME button has departed. To solve such a problem, you need to carefully disassemble the phone. Then you need to turn off the loop from the button, clarify whether there are damage on it, and re-stick it. In some situations, it helps to correct the error.

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

If the Touch ID stops working in the App Store

Very often, users notice the problem with the scanner only when entering the official Apple Store. However, if the imprint is not removed in App Store.This may also testify for malfunctions in the device.

In this case, you must perform the following actions:

• Enter the settings and go to the Touch ID password.
• Enter the code and find the "Use" section.
• Disable the App Store and iTunes Store in it.
• Reload the device.
• Go back to the settings and repeat the procedure, only this time the stores are necessary, on the contrary, activate.

It usually helps get rid of bugs.

Tech support

If nothing from the above helped, you should not despair. Experienced Apple Technical Support Specialists can help figure out why you cannot complete the Touch ID setting. To do this, you must go to the company's official website and create an appropriate ticket. Either you can search already asked questions. Most likely, the site has a large number of Discussion branches with similar problems. If consultants are offered to fulfill everything that has already been voiced, it remains only to go to the service center and try to diagnose the device. Before it is worth copying all the data from the phone again.

Dactyloscopic scanner has already ceased to be something special - today they will be seen not only flagships model Rowbut also many smartphones of a decent level. Fingerprint scanner is used to unlock the apparatus, protecting it from unauthorized access. It is used as an element of protection of some applications. This is a very convenient and reliable solution, but, unfortunately, only until the scanner ceases to react to the owner's finger.

Possible causes of malfunction

All the reasons for the failure of a dactylcon scanner to perceive the fingerprint of the owner of the smartphone and properly react to it can be divided into 4 groups:

1. Damage to the touch of the sensor of the button (with self-opening of the device or after a strong impact);
2. Failure in software;
3. The surface of the wet button or strongly contaminated;
4. Changing the fingerprint drawing (physical damage to the skin, its degradation due to frostbite, chemicals, corn formation).

Ways to correct the situation

Option 1: If you are confident that the sensor loop is damaged, take the smartphone to the repair shop. In most cases, masters manage to cope with the breakdown.

Option 2: Update software Smartphone. You may have missed the arrival of an important update, which led to the failures in the work of the scanner. If, on the contrary, the scanner stopped working after installing the update, go back to previous version firmware. You can reset to factory settings (do not forget to pre-create backupnot to lose all the information from the smartphone).

Option 3: Wet (not wet!) With a cotton wand, moistened in alcohol, gently wipe the surface of the button. Dry it and check it if the sensor has not earned. Take the button only clean and dry fingers.

Option 4: The method associated with the replacement of the imprint is very effective. The operation of the dactyloscopic scanner is not only normalized, but also accelerates. Procedure Next:

No matter how ridiculous this method looked, it works and works perfectly - verified on smartphones Xiaomi. .

Recently in news tape and B. social networks There are often discussions and opinions on new function Fingerprint recognition called Touch ID in iPhone 5S. Basically, all discussions are reduced to security issues and future prospects for the protection and access to the device. For some reason, much less often rises, it seems to me, a more pressing question - is it convenient to use Touch ID in everyday life?

It is clear that the initial print is entered into memory, then a touch is followed, then pressing the "Home" button, and as a result - unlocking the device. All this is very fun and interesting, but is it beautiful, just and easily the process looks really?

I think here it will be quite appropriate to bring several opinions or, if you want, observations from well-known persons in the world of "near-chamber" journalism based on their personal experience.

For example, this is what John Gruber (works in daringfireball.net):

Although, it can technically and right, Dustin Kurtis (the creator of the interactive magazine svbles.com, and a combination blogger), which is actually not quite so:

When the phone is blocked, unlocking using the Touch ID looks slightly clumsy; You must touch your finger to the sensor on the "Home" button, press the button and have time to press it, without removing your fingers from the sensor, and you need to manage all this to do everything until Siri has been activated. It works, but the sensations are strange.

In general, I will say this - unlocking is really "instant", but only if the lock screen is in an active condition at this moment. It was fun to watch new owners trying to unlock the device, simply by spending or touching his finger to the sensor. It would seem that a simple and logical action - unlock an iPhone - actually consists of two non-obvious: "awakening" by pressing the "Home" button and reading a fingerprint sensor. That is, the iPhone is in an inactive state simply will not react to the finger, reading occurs at the time immediately after activating the device with the usual pressing on the Home.

And John Gruber is back for his:

Touch ID does not depend on the button pressing, and there should be no delay ... Try like this: Put your finger on the Home button until the iPhone is blocked. Activate iPhone button nutrition and not button Home.. Unlock instantaneous.

What can I say: apparently, I am some kind of wrong, not of those people that usually unlock the iPhone with two hands ...
