PixelCheck: Dead Pixel Test app analytics for August 31

Buying a used iPhone? Just had your screen repaired? PixelCheck gives you a full guided screen check and six focused tests to verify your display is perfect — with a report you can share. GUIDED SCREEN CHECK Run every test in sequence with clear instructions, give each a pass or fail, and finish with a summary. Share the result as a report — proof of your screen's condition when buying or selling. DEAD PIXEL TEST Cycle through 11 full-screen colors — white, black, red, green, blue, yellow, cyan, magenta, and three gray levels. Dead pixels and stuck pixels stand out immediately against solid colors. PIXEL FIXER Found a stuck pixel? Rapid color flashing can help revive it. Position the screen and let it run. BACKLIGHT BLEED TEST A pure black screen reveals light leaking around the edges of LCD displays. TOUCH SCREEN TEST Draw across a grid overlay to verify every zone of your touch screen responds — with true multi-finger support. Track your coverage in real time. OLED BURN-IN TEST A slow-moving gray block and uniform gray screen reveal ghost images, uneven brightness, and burn-in damage on OLED displays. Adjust the gray level to catch subtle issues. SCREEN INFO View your device model, screen resolution, pixel density, display type, refresh rate, and current brightness — all in one place.
