It would be nice if it were a bit easier to go back to previous colors, but otherwise it does its job. For anyone confused, this app literally just cycles your screen through a set of solid colors; you have to visually inspect the screen yourself on each of those colors to determine if any pixels are dead/stuck. That is not something that can be done with software, so of course the app doesn't have "test results" or anything like that.

The best of its kind. It's the only app that lets you check your display for dead pixels in a comfortable way by sliding from one color to another. Lots of phones come with several dead pixels out of the box: I had this problem with the Samsung Galaxy S9+, with the Galaxy A8, with the Galaxy J5 2017 and the Xiaomi Max 3, to name a few. It's very disappointing and you'd better use this app the day you buy your phone so that you can return it if you find defects.
