## Description

Screen Dimmer – OLED Saver is a Chrome extension designed to reduce eye strain caused by PWM flicker and prevent OLED screen burn-in. It offers auto brightness control directly from the notification panel, a screen filter for burn-in prevention, and flicker reduction features. The extension runs efficiently to minimize battery use, providing a smooth, ad-free, and simple user interface for easy brightness adjustments.

By applying a dimming overlay via Accessibility services, Screen Dimmer optimizes screen comfort at the pixel level without introducing extra flicker or affecting battery life. This makes it a perfect tool to help protect both your eyes and your device's display, enhancing your viewing experience seamlessly.

## Review summary

Users broadly praise Screen Dimmer for lowering brightness and easing eye strain, aided by pixel-filter/grid features and cross-device usefulness. However, repeats include privacy/permission concerns, device-specific reliability issues on Samsung S25/S25fe, brightness resets on unlocking, and stability/visual artifacts on older Android versions. The app is beneficial for eye comfort but carries caveats related to permissions, device compatibility, and occasional UI quirks.

### Pros

- Significantly reduces screen brightness and mitigates eye strain, including PWM issues on OLED displays.
- Pixel-related features like pixel filter and pixel grid provide visual control and customization.
- Works across a range of devices (Samsung, Xiaomi) and different displays, improving usability on problematic panels.
- Ad-free experience (no ads) and generally reliable performance when it works.
- Good support for contrast adjustment on OLED displays.

### Cons

- Privacy/permissions concerns: reviewers worry about data access and broad app permissions.
- Device-specific reliability issues on Samsung S25/S25fe, including auto-started services and difficulty enabling the dimmer.
- Brightness can unexpectedly return to full on unlock/lock-screen, undermining the dimming effect.
- Stability issues on older Android versions or certain devices, including crashes and hiccups.
- Occasional visual artifacts or UI conflicts (color banding, overlay visibility) and inconsistent dimming at higher brightness.
