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.

I am shocked that this worked - I bought a used LG V20 online knowing it had really bad burn in/ghosting, was mostly going to use it as parts. It sat in my drawer for a year, then I decided to sell it. Thought to give this app a try, tried Twilight also, but that just dimmed the screen. I wasn't expecting much - I just ran it B&W for about 30 minutes, then I got busy and tossed it aside, not really even looking at it. I had someone reach out to me regarding my online listing for the phone, wanted to know if the camera worked. I powered the phone on, and to my shock, the ghosting was 80% gone! I ran the app for another 2 hours, and now it's completely gone! I'm keeping the phone! Thank you for this app! Wish I could post pictures

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.
