OLED Saver

About this app

When the brightness of the phone using the AMOLED screen lower the brightness past a certain point, the screen starts to flicker or pulsate. This is a result of the AMOLED technology Samsung, among other manufacturers, use in their displays, and the way that these types of screens operate.

With a traditional LCD screen, a light is projected through the array of pixels to increase or decrease their luminosity, and brightness adjustments are made by simply dimming this light. But with AMOLED displays, each pixel emits its own light—so in order to decrease your screen's brightness, the electrical current flowing through these pixels has to be reduced in some way. It's this reduced current that can make your screen seem to pulse or flicker.

This application solves these AMOLED problems by replacing the system functions for automatic brightness adjustment, which dims the pixels displayed on the screen without having to reduce the current flowing through them. This means it can keep the physical brightness of the screen at a high enough level to avoid screen flicker problems, while automatically reducing the actual display brightness according to ambient light, protecting your eyes. It reduces screen brightness by turning off some pixels and adding a transparent black mask layer, and then provides you with an easy-to-access control bar to further adjust the brightness. Another benefit is allowing you to darken your screen further than the minimum stock brightness level.

After the android o version, this app still effective in the status bar, notification drop-down menu or lock screen.

Ratings and reviews

Not a perfect fix but far better than anything else I've found. My Samsung S9 has this issue where sometimes only a few lines at the top of the phone would appear. I found a few workarounds (like tapping the Always On Display before turning on the screen) but this made it so that the screen always turns on all the way. It does affect the picture somewhat, but I think that's a hardware issue with my phone, not the app. Not a total fix but the best improvement I've seen.

I have a galaxy s9+ (old phone by now) that started having issues from the moment I bought it, and this app has helped me avoid needing to buy a new phone over the years. Every time my screen acts up, it is because this app isn't on. Sometimes it does turn off for reasons I don't know, but its a small price compared to getting a new phone because of the screen not working correctly...

My Samsung Galaxy S9+ run into the "green tint" issue. After one week the problem gets even worse, being impossible to see what's on the screen. Since Samsung is unable (or unwilling) to fix the problem caused by themselves with a firmware update, this app is my last chance to keep using my mobile without having to replace the whole screen. When the device warms beyond 40° C the screen keeps green or purple, but OLED Saver makes perfectly possible to read texts. Thank you for this awesome app!
