How to run the test

Start at medium brightness, then try other levels — how visible a mark is can change with the color and the brightness.
Start the test and look at each solid color for a few seconds.
Pay most attention to gray and red — burn-in usually shows best on these.
Check where your phone's keyboard, status bar and navigation buttons usually sit.

Burn-in or image retention?

Image retention: a temporary mark that fades gradually after the content changes. It can take anywhere from minutes to longer, depending on the screen.
Burn-in: a shape that's still there after hours or days. The pixels in that area have aged faster than the rest and the damage is permanent.

To tell them apart, run the test, use the device normally for an hour, then run it again. If the shape is fading, it's retention.

Buying a used phone or TV?

Burn-in is one of the most common hidden problems on second-hand OLED devices, especially phones used for navigation or gaming with a fixed interface. Run this test before you pay — it takes less than a minute.

Frequently asked questions

Can burn-in be removed?

Real burn-in is permanent. Some TVs and monitors have a pixel refresh routine that can reduce mild unevenness, but a strong outline usually stays. Image retention, which fades on its own, is a different and harmless thing.

Do LCD screens get burn-in?

LCDs don't age the same way, but some can show temporary image retention after a static image stays for many hours. It normally fades after a while of varied content.

Which color shows burn-in best?

Mid gray shows most burn-in. Then check red, green and blue: aged areas often show as a tint in one of them, for example a yellowish or pinkish shape.
