This code is used to test the LCD screen of mobile devices. It can mainly perform testing of following functionalities
  • Test pixels and screen by turning all pixels to Red / Green / Blue or White
  • Test vibration
  • Test dimming of pixels
  • Test Camera
  • Test sensors such as accelerometer,proximity, magnetic etc…
  • Touch testing
  • Sleep mode
  • Speaker (By playing ringtone)
  • Test keys
I have tested it in my Galaxy Y. Hope this is available in all Galaxy mobiles and almost all Android mobiles.
