C Y S (Check Your Screen)

Hi. I am a University student who is programming as just for fun. This application will help you find out your smartphone display's defective pixels. Easy to use. Just tab your smartphone and find defective pixels. (Of course, you have to use your eyes. This application does not detect defective pixels.)

(This application have 9 colors. (Black, Gray, White, Red, Green, Blue, Yellow (Red + Green), Pink (Red + Blue), Sky-Blue (Green + Blue)))
