Tasker: App Specific Screen Brightness [Very useful]

Introduction with today's project: An extremely simple yet immensely useful & convenient tasker project. This tasker project automates your android smartphone's screen brightness to act according to the app currently opened/used. 

For example, the screen brightness will be increased when the camera or the gallery app is opened, to facilitate capturing of photos/videos & will be restored to the normal brightness state after the app is closed. This definitely makes capturing photos/selfies or videos a more enjoyable job! 

This is extremely useful for people who don't keep their screen brightness at maximum, due to the ever insufficient battery life, but often feel the need to manually slide the brightness up, while clicking pictures or viewing the gallery or watching videos etc. After creating this tasker project, you'll never need to adjust the brightness level when using a particular app(s). You'll be able to predefine the level of brightness which will be applied when such apps are opened, and will revert to the regularly used(predefined) level of brightness once the apps are closed.

PREREQUISITE: You'll need the app: Tasker (Please turn off beginner's mode in preferences)

In a nutshell, it basically consists of 3 simple steps- Selecting the apps, Setting the increased brightness level & Setting the brightness level to return to, once the app is closed.

Now let's get into a detailed tutorial.

Step 1: Click on the '+' button at the bottom right corner and select 'Application'.

Step 1
Step 2: From the list of the apps, select the Camera & Gallery apps you use.
(You can select more than one camera/gallery apps like retrica/beauty plus/camera 360 etc too). (Make sure only "App" is active at the bottom, while "Services" and " Invert" options are inactive.)
Step 2

Step 3: Click on "New Task +" and give it a name: "Brightness Up"

Step 4: Click on the '+' button at the bottom and browse to Display -> Display Brightness.
  • Slide to set the value of Level to the maximum value possible (eg. 255). 
  • Click on the '+' button at If and type %BATT in the variable box, select "Maths: Greater Than" from the middle box and type 19 in the value box and press the back button. (refer image below)

    [by adding this IF statement, the screen brightness will be increased only if the battery is at least 20%. This acts as a power saving mode for this feature]
