What to do if the fingerprint works. Does not work fingerprint on android

Touch ID is a device for recognizing the fingerprints of iPhone and iPad users. Thanks to reading, you can unlock the phone or instantly logged in applications such as Amazon, LastPass. Also, the function is used in the AppStore for payment.

After installing the new iOS 10, some users have troubleshooting in the scanner. Distinguish several varieties of faults:

Phone hanging at the refrigeration recognition stage;
Non-working sensor while charging iPhone;
Sudden reset of previously configured prints.

Also the reason that the touch ID does not work on the iPhone may be a drop or punch of the phone, as a result of which the sensor was damaged. Consider more detailed how to quickly solve the problem and return the print scanner into normal state.

Repeated scanner

If the iPhone freezes in the process of scanning a print, the sensor should be reconfigured. All data on saved "fingers" are in the phone settings ("Touch ID and Password" window).

Delete all existing prints, disconnect the "Unlocking iPhone" and " ITunes Store., App Store."And then restart the phone. After turning on the device, go back to the settings and add new prints for several fingers. This re-configuration allows you to reset the erroneous configuration and resume the scanner operation at the program level.

No response Touch ID during charging

There are cases when the Touch ID does not work while charging an iPhone. In this case, you should completely discharge the phone, then connect to the power and charge up to 100%. During charging, it is desirable to enable the "aircraft" mode and do not use the device. Then make Soft Reset (without data loss). After these actions, the biometric scanner will work normally. Do not use the fake charging for iPhone, after connecting it to the device, functional failures may occur.

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

Improvement of the sensor in the cold

In the cold, prints are recognized worse, often disaster biometrics of the phone. To improve the work of the Touch ID at low temperatures, enter a new cold fingerprint to the existing scanner database. It helps an iPhone to remember the current state of the finger and in the future it is better to recognize it.

Replacement of the touch ID

If the reason for the non-working scanner is the hardware breakdown, in the smartphone settings (Touch ID window) will not be displayed previously saved data. There will be no possibility to add a new imprint. The only solution is to check the scanner cable.

Disassemble the phone and remove the HOME button from the display module. Check the connection of the loop if it just moved away, just just reconnect it and collect the phone. However, most likely it will be broken. The figure below shows a visual example of the loop of the "Home" button (the location of the breakage is indicated by the red line curve).

Replace the loop is not possible, because the "Home" button cannot be disassembled. Thus, Apple protects devices from the substitution of a biometric sensor. You should replace the HOME button (when buying parts in the configuration there is a corresponding loop).

It is not surprising that such a thin system often can "capricious", which is why the fingerprint on the iPhone 5S does not work.

When Aidi's touch does not work on Athos, most people are waiting for the OS update, but no one is going to wait so long to be able to deal with how to do if the adjustment is impossible.

The latest models are equipped with a "home" key, which have a dactyloscopic scanner. Since people actively use it, there is nothing surprising in the frequent breakdown of this mechanism. The failure is able to occur after random fall, damage to the case and much more. There are rare cases when a mobile phone is faulty in the production stage or the store receives a recovered smartphone, and after the update they are detected. If not much time passed, and the smartphone writes a failure, it is recommended to immediately return it to the store.

Climatic conditions are also able to affect the functionality. A sharp temperature difference or the advantage of cold saturated air moisture affect the functionality of the smartphone. Some users do not know how to customize the fingerprint scanner, which is why they register their physiological data on the street with a temperature below zero. In this case, the root of the failure is not in the smartphone itself, namely in changing the papillary pattern of the pattern.

It is impossible to independently fix various changes, but Ayidi's touch detects various changes, after which failures begin. There are messages like "The fingerprint sensor error occurred." The update corrects defects, only such manipulations does not always trigger properly.

Users who lack money for repairs in the official service center are sent to local "crafts." Many of them change the situation to the worst - "home" ceases to respond to pressing, and they themselves do not know what to do in one situation or another. After replacing a bunch of other faults appears. The problem is the mechanism itself - Apple designers created it so that it cannot be fixed. Only its replacement, like motherboard And other spare parts, able to completely repair the mobile phone.

For independent repairMost likely, the sensor is blocked, due to the invasion of the protected area of \u200b\u200bthe system. It can be fixed only in the official service center.

The second way to solve a malfunction

If the Touch ID has stopped working, and it does not recognize your fingers, then you should use other methods that are not so effective as the previous one:

Reset the basic parameters on the device, while you can save files and contacts. For reset, go to the main settings menu, then "Basic", "Reset all settings". When all items are done correctly, restart the gadget.

Chemicals

Then the cleaning agent to get rid of pollution and not only the key, but also the touch of Ayy will return to life.

Third-party programs

This option Will not change the state of the iPhone, but you can use the phone as before. Such an uncomfortable method, although it is better than the incapable item. The "Home" image is transferred to the main screen, after which it is used, like the mechanical key.

Even though it is not an exquisite method, but it will allow you to use iPhone 5 to the campaign in service center. The main thing is not to carry the device to the above "craftsmen" that do not know how to install a fingerprint to Apple's products correctly.

Installing a new mechanism

Engineers took care of a similar replacement of the mechanism, so everything is not as simple as it may seem at first glance. When the home button does not work, in some situations it is easier to buy new smartphone. The usual user will not open the mobile phone without damaging some details, even many specialists are not ready to take on such a risk, which is why only highly qualified wizards with the necessary tools are required. The replacement is only needed in the event that the button does not work on all operations. It is worth adding only to the official service center, otherwise the likelihood is that the fingerprint on the iPhone 5S and other series appear other breakdowns.

Replacing the mechanism for professionals

Before any manipulations, you need tools that allow opening iPhone 6 without unnecessary deformations. To begin with, come in handy:

Tweezers.
Small blade.
Screwdriver plus.
Screwdriver-minus.
Sucker.

To start, unscrew several screws located next to the power connector. Next, hold the screen thanks to the suction cup and do not forget to help your spatula. When disconnected, the hands should not tremble, since the touch loop at any time breaks away from negligent circulation. The blade will allow you to disconnect the connector and raise the display. Disconnect the protection from the loop and, after unscrewing several cogs, disconnect the desired part. After the procedure, there are no errors on the similarity "the touch of Ayida does not work on iPhone."
