First Apple smartphone with fingerprint scanner finger touch ID became the iPhone 5s, which entered the market back in 2013. Since then, the "apple" corporation has managed to develop and begin to implement the second generation of the fingerprint module, which is characterized by increased recognition speed and increased reliability. However, problems can arise in the operation of any Generation Touch ID, so revision website I decided to talk about five ways that will fix a poorly functioning fingerprint scanner in iPhone and iPad.
Activate Touch ID in iOS Settings
Before you start looking for the cause idle scanner fingerprint in iPhone and iPad, you should make sure that it is enabled in the settings operating system iOS. To do this, you need to launch the "Settings" application, and then go to the "Touch ID and passcode" section and activate the toggle switches opposite all the parameters associated with this module. If they are already enabled, then they can be turned off and on again in order to exclude the possibility of some kind of bug.
Clean the module from dirt and dust
Because Touch ID scans your finger, you should always keep it clean. Of course, you should not overdo it with cleaning it, but dirt and dust can cause bad work the entire module and lead to incorrect fingerprint recognition. You can clean Touch ID from dust and dirt using a special solution for cleaning electronics. It should be sprayed on a microfiber cloth and thoroughly cleaned the entire module for several minutes, and then tested for its operation.
Update your iOS operating system to the latest version
Despite the fact that the iPhone and iPad are among the most reliable in the world mobile devices, in the operating room iOS systems there may be some glitches and glitches. As a result, the Touch ID module may not work correctly on certain firmware versions. This problem is solved by updating the device to the most latest version iOS, which probably does not software problems with TouchID.
Finger position for scanning
In some cases, unlocking iPhone and iPad with Touch ID may not work for the simple reason that the fingerprint scanner cannot scan. To help him with this, you should place the fingertips on the entire fingerprint scanner. Also, Touch ID takes some time to complete the scan, so don't take your finger off the scanner too quickly.
Adding more fingerprints
Up to five fingerprints can be added to all iPhones and iPads to unlock the device. Apple does not impose any restrictions on this account, so the same finger can be scanned several times, thereby increasing the chances of successfully unlocking the device with it.
If all the described methods for solving problems in the operation of Touch ID did not help, then you should think about visiting a service center. It often happens that the fingerprint modules in the iPhone and iPad fail and the only way The only solution to the problem is to visit the ASC. Note that repairs or Touch replacement ID is possible only in authorized service centers that are able to "bind" new scanner fingerprints to the old iron.

Installation by Xiaomi fingerprint scanners on their models has become more commonplace than a symbol of an elite device. fingerprint on Xiaomi Redmi 3s was one of the first swallows to promote this technology to the people.
Already, most of the new Xiaomi tablet phones can boast of having a high-precision scanner. For example, slightly enlarged Xiaomi Redmi note 4 or even Xiaomi Mi Max "semi-tablet". The newest representative of the sixth Xiaomi lineups Mi6 inherited and received an improved sensor hidden under glass on the front side of the phone.
In some budget models, like Xiaomi Redmi 4A, such a sensor is not provided at all, while in a fairly fresh Xiaomi Mi 5 it often works intermittently and may disappear completely.
Consider the algorithm for adding a new fingerprint.
How to turn it on
Setting up a fingerprint on Xiaomi for the first time is as follows:
- We go to the "Settings" menu and select the "Lock screen and fingerprint" tab in the "System and device" list;
- Next, click on "Screen lock and fingerprint". In the new open menu pay attention to the lowest item in the window - "Add fingerprint";
- The system offers to set a graphic key in case the supplied print on the scanner does not work or the device partially fails;
- Repeatedly apply any finger (the same) to the surface of the scanner of your smartphone. The success of each stage of the scan will be reported to you by an animation with filling the circle and a slight vibration of the device.
- If everything is done correctly, you will receive a notification about successful setup. Your device is ready. Additionally, you can install and select another fingerprint.
The location of the sensors will tell us how it is more convenient to make a scan. For example, in Xiaomi Mi 5s, the sensor has a rear location (by default for the index finger), and in Mi 6 it is in the front (for the thumb).
However, things don't always go so smoothly. It happens that in certain models, as in Redmi 4X, there is no fingerprint menu in the settings or the phone does not respond to touch.
Possible problems
Xiaomi smartphones, like samples from other manufacturers, are not perfect. Some of them are subject to systematic problems (namely: Xiaomi fingerprint not working) that many users experience.
There can be several options for glitches:
- fingerprint scanner works intermittently;
- the saved sample is missing;
- there is no reaction to pressing the sensor field;
- the corresponding item in the settings menu has disappeared.
To eliminate these unpleasant phenomena on your smartphone yourself, you need to perform the following actions:
- unlock it graphic key home screen set during setup;
- fully discharge the device before automatic shutdown;
- charge the battery up to 100%;
- wipe the touch zone of the sensor with a dry, clean cloth;
- start the smartphone (the sensor should work).
Often tactile recognition stops working on Xiaomi Mi 5, due to shortcomings official firmware. If the phone still does not find it or the menu disappears, as if it never existed, you need to contact the Xiaomi service center. There your phone will be held detailed analysis failure and, if necessary, repair or replacement of the part.
Nuances
Not in all Xiaomi cases with a fingerprint scanner, you should take it in for repair or “torment” with the firmware yourself. New budget and flagship models smartphones at the start have a "raw" firmware. Developers simply do not have time to eliminate all its shortcomings. Most often, the solution to such troubles is a new update. Thus, the work of the fingerprint scanner on Mi 5s has been fixed.
A smeared or wet finger can become a banal reason for blocking screen fingerprint recognition. Cuts and scars also negatively affect Xiaomi's ability to lock the screen.
Sometimes the problem is solved by switching the language to English, then deleting the poorly recognizable old scan sample, and replacing it with a new one.
The last option is to disable the idle scanner on the phone.
Removing a fingerprint
For the Xiaomi Mi and Redmi phone lines, creating a new scan sample occurs exactly like turning off the old one.
The removal process takes less than a minute:
- enter the "Screen lock and fingerprint" menu (the path to it is indicated in the second section of the article) and enter the password.
- by clicking on " New password", we confirm the deletion of the scan on the smartphone.
After turning off the sensor, it will not respond to touches until the owner wants to set a new profile.
