Comments on Screen Dimmer – OLED Saver for Android
★★★★★Abdullah Al Abtahi· Feb 4, 2026
This does a really good job in the Samsung Galaxy A24 4G I am using. Quite a blessing considering the terrible PWM Samsung devices usually have. There are some hiccups though, and I wonder if some updates could be implemented firstly when changing orientation and opening any app from the lock screen goes to full brightness and I have to close my eyes just in time reduce its intensity on my eyes secondly when using Google Maps the screen starts to dim and becomes darker than what it was before.
★★★★★Mathew S.· Apr 1, 2026
Great app. Fixed basically all my eye strain issues in my Pixel phone. One update I would like it see is the possibility of dimming the screen more in a dark room. It feels too bright if I'm laying in bed or something.

The app dims the screen, but the permissions are concerning. Android privacy settings show Screen Dimmer has “full access” to my device, and it is the sole app with full access. I understand Accessibility may be needed for some dimming features, but full access to literally everything on the device is not justified. Even after closing the app and disabling background activity, it still showed continuous access. Uninstalled.

Screen goes full brightness when orientation changes or during certain transitions. Every time you use it you have to keep granting permissions in settings through lengthy menus. Ad free I guess...

It made my screen brighter instead of dimming it
