PixelCheck: Dead Pixel Test app analytics for May 3

DEAD PIXEL TEST Cycle through 8 full-screen colors — white, black, red, green, blue, yellow, cyan, and magenta. Dead pixels and stuck pixels stand out immediately against solid colors. Tap to cycle, swipe to go back. TOUCH SCREEN TEST Draw across a grid overlay to verify every zone of your touch screen responds. Track your coverage in real time and make sure there are no dead spots.
