Comments on Screen Dimmer – OLED Saver for Android
★★★★★A. Vest· Sep 3, 2026
This app is lifesaver - no more headaches and tired eyes! Easy, simple, straightforward. The eye strain from reading ebooks for hours became a problem this app helped solve. Now I can enjoy my Cloud Library** ebooks again. Took me a few days & some dark screenshots to adjust (there's an easy screenshot feature / shortcut that I failed to see at 1st). Screen dimmer is a 5-star, essential App for me. (*Cloud Library bc Amazon is ruining Kindle's user experience like it ruined Alexa with Alexa Plus).

Save my eyes! Prefect solution for OLED screen pwm sensitivity issue.
★★★★★J M· May 18, 2026
Dims the screen without reducing brightness (which means no increasing flickering from PWM that causes eye fatigue for some people) I prefer manual mode & and ise the pixel filter (4 pixel pattern) to further desaturate (intentionally) my screen. Did I mention it's free, without ads?

It made my screen brighter instead of dimming it

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...

Not a screen dimmer, just an app to replace your phone's built-in brightness adjuster EditToReply: how? I wanted my screen dimmed below hardware limits, so artificially. Your app only adjusts the hardware part. What is different from the phone's built in option? Edit2:Then the app name is very misleading. But I'll remove one part of the review then and up the rating to 2 for a legit reply that isn't AI.

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.
