Override your screen brightness temporary.
[Use case] Show others your photos
If you set low brightness for battery-save, screen brightness is too dark for others to see.
But if you change the brightness setting, you must undo it every time. That's a pain.
If you use "Temporary Brightness", overriding brightness stops automatically when the screen turns off.
It doesn't work perfectly on Xperia devices.
The brightness adjust feature of Xperia devices are different from pure Android OS's one.
