Worked fine. Took about an hour and a half to clear image persistence, since LCDs don't technically get burn-in. I used both the color rotation setting and the black and white setting. My image persistence wasn't too severe, I noticed it quickly and then went about solving the problem. However, it can take a long time to clear an image persistence problem, just because mine cleared in an hour and a half, doesn't mean yours won't take longer. Depending on the image was static there can have a large bearing on how long it will take to get ride of. This is not something that always has a quick fix solution really.

Be patient, this will take time. The app is excellent and worked for me. Screen burn on my Galaxy S20 was annoying, especially when the background was white. For my result, I used the black and white for about 4 hours, then the coloured option for around 3. Very pleased I didn't have to replace the screen, for cost reasons, but more importantly the inconvenience of being without the phone. Highly recommended, well done guys.

Removed the ghosting from the edges of my keyboard pretty well. Bottom bar isn't completely gone yet, but might after more use. Tip: do this sooner rather than later. The more visible the ghosting, the harder it will be to get rid of. It only took about a half hour for noticable results for me. Also, make sure you have a standard LCD displace. LED, OLED, and OLCD will NOT be fixed this way; you need a different app and it is less likely that will work either.
