Useful for finding glitches in The Matrix. I get deja vu looking at certain pixels!
Very good freeware for finding physical screen and calibration defects. Would love to see grid display.
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
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
Too small to do any good Looks like its only for phones, doesn't take up the full screen on my 7 inch screen. Otherwise does what its supposed to in the small space it takesup
