Doctor OLED X

If you’re going to buy a phone with an OLED display, then this app is a great diagnostic tool to have when your checking your display for color consistency. The app will display a wide range of colors that makes it very easy to see if your OLED screen is displaying colors properly. Also, I know it was a small thing for me to nit pick about, but thanks so much for removing the uninterruptible music that would play while the app was open. I love being able to play my own music in apps. I’m givi

Does its job, but is sort of lack luster in terms of features.

This app is a good screen tester. Don’t expect it to balance your checkbook - its a screen tester. It does that fine. Developer: the button for “OLED & App Info” leads to a text display that’s both editable and a user trap. You can’t back out of it, apparently. Requires a force quit if you click anywhere and enter edit mode as the Exit button disappears in edit mode.

Not what I was looking for, but still useful for other things.

The app didn't show my keyboard screen burn in any of its tests, nor did it fix it. But free RGB cycling videos did.
