Screen Test vs Domain Checker

Check your iPhone display in seconds. Screen Test fills the screen with pure colors so dead, stuck or faded pixels stand out, and helps you test touch, burn-in and uniformity before you buy or sell a phone. Free: • Color test: white, black, red, green, blue, yellow, cyan and magenta at full brightness. Tap for the next color, long press to see its name. Premium (one-time purchase, no subscription): • No ads • Touch grid: drag over every cell to find dead touch zones • Multi-touch: see how many fingers the screen detects at once • Gradients, gray levels and checkerboard: spot burn-in, banding and uneven panels • Custom color: fill the screen with any color • Stuck pixel fixer: rapid color cycling, with a photosensitivity warning • Used iPhone check: run the tests in order, mark pass or problem with a note, share a PDF report and keep a history on your device Who it is for: • Checking a used or new iPhone before you buy it • Finding dead pixels, stuck pixels and OLED burn-in • Finding dead touch zones after a drop or a screen repair • Repair shops checking a display before and after a repair Bought Screen Test before it became free? Premium is already yours. Use "Restore purchases" in Settings if needed. Tips: clean the screen first, test dark colors in a dim room and light colors in a bright room.
