I'm looking for a way to reduce the real brightness (the backlight) of my lcd. I'm using android 4.2.1 on a Star b94m/b943.

I search for apps, and i found RootDim, which can decrease the light below the minimum 30/255 (default by android). I found another great app, Velis Auto Brightness, which allows to control the brightness in function of the light sensor. It can't go below the 30/255. So i thought if there were a method to reduce the default android brightness i could use Velis Auto Brightness (so auto brightness) AND use lower than 30/255 levels.

I tried this tweak of build.prop

How can I reduce screen brightness below the minimum without an app?

but it didn't work. Any other ideas?

Thank you!

  • If you don't mind installing a custom ROM, CyanogenMod ROMs allow much more control of the Brightness setting...Including going below 30/255. – Namuna Jun 26 '13 at 20:44
  • This answer should work. Otherwise, try Gravitybox app which definitely would do the job. – Firelord Jul 2 '15 at 21:17
