Control screen brightness with fingerprint sensor thanks to DigiLux


DigiLux is an application that makes use of the new Oreo Android 8.0 print sensor API to be able to control with gestures, the screen brightness .

When I get a big cell phone (about 5.5 inches or more), I realize how uncomfortable it is to get the notification center when I'm holding it with one hand. It is true that, since Nougat 7.1, certain devices could remove the notification center with the fingerprint sensor . But if you always do this to adjust the brightness, we bring good news.

The option to remove the notification center is really useful, but if we change the brightness of the screen, we are still in the same. The bar for adjusting the brightness is at the top . So it's still a bit uncomfortable to get to it. Solution? DigiLux An application that uses the fingerprint sensor API available to Oreo developers, you can adjust the brightness with the fingerprint sensor.

Not available for everyone, for now


Before running to download it, say that it is only available for terminals with Android 8.0 Oreo and those belonging to a list. In addition, need not be the root of the work . The developer says that later he will try to get more compatible devices in the list. For now, we only have these:

  • Google Pixel 2 XL
  • Google Pixel 2
  • Google Pixel XL
  • Google Pixel
  • Nexus 6P
  • Nexus 5X

They are Google devices and they have Android 8.0. But according to the developer, the application makes use of the FingerPrint Gesture API available from API 26 . Some functions that will work in tandem with Android's accessibility services. So in the future, it may be compatible with more models.

A simple but very useful application

Now let's go back to the application. DigiLux, which is called, allows you to set the brightness of your Android screen by gestures on the fingerprint sensor. The gestures are reduced to:

  • Sliding, we raise the brightness little by little
  • Sliding, we reduce the glimmer little by little
  • Sliding to the left we reduced the brightness to the minimum
  • Sliding to the right we increase the brightness to the maximum

In this way, you do not have to take your thumb to change the brightness. Simply while you're using, place your finger on the back sensor, slide up or down, and you're done. Adjusted brightness Say this allows you to go a little further and get a lower brightness than the device offers by default . Ideal for those times when we check the bed nets before bed.

As a customization feature, the application allows to set the brightness control at the bottom of the screen and also to change the color of the bar .

A free app but with certain payment features

An application that is free but has certain functions that will be unlocked with a purchase within the application itself. Explain that these types of payments are no more than the "payment" for the developer's work. The premium features you now have are those that choose the color of the bar according to the background of the screen and the brightness smaller than the default.

I always say the same, which Google does not give us by default, the community is there to patch and meet the needs of a group of users.
