## Description

New: guided Screen Check with a shareable report, Pixel Fixer for stuck pixels, backlight bleed test, and true multi-touch testing.

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.
