明るさ自動変更君

I want the brightness of the screen to be adjusted automatically, but the automatic adjustment that is included in the smartphone from the beginning is a little different from my feeling!
I set the brightness of the screen to the darkest setting, but it's still too bright and painful!
I made it to eliminate such dissatisfaction.


You can decide the point (brightness sensor value) at which the screen brightness is switched and the brightness to be set.
The brightness of the screen can be specified from -100% to 100%, and by setting it to a negative value, you can make it darker than you can normally set. (-100% does not make it completely dark)
*Currently, on Android 12 or later, the screen cannot be operated at negative brightness, so please set it from 0 to 100%.

The operation mode can be selected from "stop", "only when canceling Sleep", and "always".
If you set it to "Only when canceling Sleep", it will operate only from when the screen turns on until the value of the brightness sensor stabilizes.
(If you move from a bright place to a dark place, etc., please turn the screen OFF → ON once.)

You can pause/resume the operation from the status bar.
You can also specify the brightness of the screen when paused.
(Useful when you want to temporarily fix the screen in a bright state, such as when issuing coupons at a store.)
*Android 13 or later requires user permission to use notifications, so please allow notifications when using this function.

Even if you restart your smartphone, it will automatically start working.

It does not include any extra functions such as advertisement display.


There are individual differences in the brightness (illuminance) values ​​detected by smartphones.
Please refer to the "current illuminance" displayed on the app to find the setting that is comfortable for you.
You can also launch the app by touching the notification on the status bar.


On Android 6.0 and later, brightness cannot be changed without user's permission.
The setting screen will be displayed when you start it for the first time, so please allow it.
(Requires permission to change brightness and permission to set negative brightness)

In the previous version, it was possible to set the presence or absence of the notification icon, but due to changes in Android specifications, it became mandatory to display it, so it was removed from the detailed settings. note that.
