No good on moden devices which no longer have a dedicated menu button. Was great in its day, but now seems to have been abandoned by its developer.
Useful for finding glitches in The Matrix. I get deja vu looking at certain pixels!
No good on S7 The first screen asks to press menu button but the galaxy S7 6.0.1 doesn't have a menu button to access the test cards
Very good freeware for finding physical screen and calibration defects. Would love to see grid display.
Oooh. Pretty colors... So I'm happy that my screen will display all the colors this app will do. But just how am I to calibrate it? Hmmmmm?
Only shows color images, doesn't calibrate touch screen
This will assist an applicator with calibrating a pesticide sprayer.
