Works great on Samsung S9 Plus no bloatware no ads! Just make sure to turn off notifications and terminate the app when you're done using it. Yeah there's Miss Spelling's in some of the text but it's not a big deal and this will show you all the main colors of your screen to see if there's any burn in.

there is a lot of misspelling/typos. it lets you cycle through different colors then tells you if you saw a difference in colors have it looked at by a professional. all that really needs to do is cycle through different colors most people that are downloading this already know there is some static image retention

Doesn't light up the whole screen, there was always a black strip up at the top of the screen where I was intending to check. Being that that's where notifications etc are, I feel that would be an important place to be able to check.
