OLED Saver is a free utility app for mobile devices from developer MrJS. This screen display tool is made for users who own smartphones or tablets with AMOLED displays that exhibit flickering and oscillations on low brightness. It lets them calibrate levels to help mitigate these side effects.

Where apps like Always On AMOLED take advantage of the battery-saving benefits of OLED display technology, OLED Saver aims to address one of its most apparent flaws and how it handles power management on a per-pixel basis. It does so with the help of some software tweaks and optimizations.

Flicker no more

OLED is one of the best display technologies available to consumer electronics right now. They offer high saturation for vibrant colors and deep black levels since each pixel is individually lit. The latter employs a per-pixel electrical current management system that can result in screen flickering issues when brightness is set to low. OLED Saver is an app that can help you address this issue.

This app basically lets you calibrate your screen's lowest brightness level threshold to help mitigate the effects of said flickering issues. Open the app, and you'll get a simple pop-up window to get you started. From the top, you get an Enable Service toggle, Brightness and Lux values, and a Minimum Brightness slider where you can start adjusting to your preferred level.

From there, it's a matter of tweaking the brightness low enough, while ensuring flickering does not happen. The result essentially places a virtual tint on your screen. The only thing to take note of is that the app itself has not been updated in a while. You can use it as is. Just don't expect any new features or fixes to come any time soon.

A handy disclaimer

Is this app fake? That’s far from the truth, but its effectiveness is highly debatable. While it can fix some minor OLED burn-ins on a smartphone, keep in mind that a simple app like this can’t undo prolonged burn-in damage on a device. Its effectiveness may vary depending on the OLED’s condition. If you think the damage is too severe, you’re better off sending your device for actual repairs.

Simple but effective

In summary, if your device has an OLED display and suffers from flickering issues in low brightness, OLED Saver is a must-try that can help address it. It's simple and intuitive to use, and the single brightness slider is all you need to start calibrating your display. It hasn't been updated for some time now, but it still works as intended.
