My L90 has no auto-brightness option. Could anyone please suggest a way to fix the issue?

The L90 lacks an ambient light sensor, so there is no true auto brightness method.

XDA user gdjindal has a unique tutorial for adding a pseudo-automatic function on the Optimus L9 (it'll most likely work on your phone as well): link


Other option is to use my app. It is real auto brightness. "Auto Brightness by PP"

  • Tell us why we should use your app. Features, good reviews? I'm not just gonna follow a random link. Mar 27, 2016 at 18:22
  • You can see on good rate (4.5-4.6), and positive review. Even though it has a few download count because I just put it into app store this year, but the range is going up. More feature please read in the app link, to prevent "too much promote app" rule. Thanks. Mar 28, 2016 at 2:39
