Officially, support for a fingerprint scanner appeared in Android 6.0, but many users still perceive it only as a means to unlock their smartphone. Meanwhile, the scanner can be used to press the Home or Back buttons, open the curtain, shoot with the camera, launch applications, protect passwords, SMS, photos and bank accounts. And if you know how to use Tasker, you can assign almost any action to the fingerprint scanner.
Let's immediately make a reservation that in this article we will talk about smartphones with Android based 6.0, in which the fingerprint scanner and access to it are implemented according to Google requirements. Only such smartphones allow third party applications use the scanner for your own purposes. Chinese and some other smartphones with a fingerprint scanner and Android 5.0/5.1 are not suitable, since although they support unlocking the smartphone with the touch of a finger, they do not have an API with which third party software could use it.
1. We attach a “Home”, “Back” or any other button to the scanner
Probably the most useful use that you can come up with for a fingerprint scanner is to attach one of the hardware or on-screen buttons to it, be it “Home”, “Back” or “Browse”. All this can be done with the Fingerprint Quick Action application.
Install the application, check the box next to “Allow Fingerprint Quick Action”. The “Special” window will open. capabilities”, in which you need to find the application and enable it. Then you can assign one of many actions to a single, double click or swipe on the scanner, including the “Back” and “Home” buttons, as well as “Turn off screen”, “Show notification panel” (as in Google Pixel), “Split screen” (to run two applications simultaneously in Android 7.0) and others.
Keep in mind that the double-tap and swipe functions are experimental and therefore work very poorly (in fact, they don’t work). You should limit yourself to just a single click.
2. Launch applications
The same Fingerprint Quick Action allows you to launch applications using the scanner. This can be very convenient if you most often use a smartphone, for example, to communicate on Telegram/WhatsApp or make calls. This way, access to your phone or instant messenger will always be at hand.
You can select an application in the same way as assigning a button. You need to scroll the list of actions to the very end and select Launch app or shortcut (yes, the application is not completely translated), then the Single tap app or shortcut option will appear in the main application window. Here you can select an application.
3. Protecting applications
Using a fingerprint scanner, you can not only launch, but also protect applications. To do this, you can use App Lock - an application that allows you to block access to selected applications using a PIN code, pattern or fingerprint.
It's very easy to use. We launch the application, turn on “Unlock with fingerprint”, then enter either a PIN or a pattern (here it’s called a pattern), skip the screen asking you to enter your email, on the next screen go to settings, select App Lock, activate and return. A list of applications will appear on the next screen. To enable protection, just activate the switch next to the application name. Now, when you try to launch the application, you will be asked to place your finger on the scanner.
However, you shouldn't take App Lock as really serious protection. All you need to do to bypass it is to either kill the App Lock process or uninstall the application. So this is more likely to be protection from children or simply technically illiterate users who may have a smartphone in their hands.

A fingerprint scanner has become a mandatory type of security. Its main task is to recognize the user, but in addition, the sensor can simplify navigation on the smartphone. Companies such as Google, Gionee, Oppo and Xiaomi already allow the use of a fingerprint scanner to access the notification panel and camera. The sensor located on the back of the device can control the audio player, power and many other functions. However, for this you will have to download special software.
Will need free program Fingerprint Gestures from Google Play. Once installed, you need to enable the "scanner gestures" option. Then you will be able to configure 3 modes - single tap, double tap, swipe left and right. Each mode can be assigned its own action:
- go back to main screen, to the list of recently launched applications;
- power off, reboot (root rights required);
page scrolling (root rights required); - notification panel control, access to quick settings;
- music playback, pause, next/previous track (works on Android 6.0 and above); changing the screen orientation, sound profile, turning on the flashlight (Android 6.0 and higher);
- launch the selected application;
- search, screenshot, call assistant (root rights required);
- split screen, go to last running application(only works on Android Nougat 7.0).
I checked the operation of the application - everything functions without problems, gestures on the fingerprint scanner are tied to commands or quick access to applications.
How to take photos using a fingerprint scanner?
So far, only a few manufacturers have equipped their devices with this option by default, but with the Dactyl Fingerprint Camera program, the scanner of any device turns into a camera control tool.
The Dactyl app is available in Play Market in two versions. The free one contains advertising, the paid one (130 rubles) does not. When you launch it for the first time, the program will tell you which of the applications installed on your smartphone are compatible with it. Among the most popular are WhatsApp, Facebook, Instagram messengers (only on Android Nougat 7.0), as well as cameras Prisma, Google, Retrica, Candy, Snap Camera HDR and Manual Camera.
LG Camera, AZ Camera, Proshot and Cameringo+ are not yet supported, but you can send a message to the developer to set up compatibility with the app you want. Dactyl Fingerprint is updated quite often, it is quite possible that the next version will work with the program you need.
In all supported applications, you can take pictures using the scanner. To release the shutter, you simply tap the sensor, just like you would when unlocking your device. This option is especially convenient to use on smartphones with a large display.
Now you know how to set up gestures for the fingerprint scanner on Android smartphones, and also take photos with it.
Modern smartphones, including budget Chinese models, now have fingerprint scanners. With their help, you can unlock your mobile device with one touch. We'll tell you how to set up and effectively use this sensor in your smartphone in this article.
