Test my iPhone screen
Spot dead pixels, discoloration, or burn-in.
We'll show a sequence of full-screen colors so you can look closely for spots, lines, or tinted patches. The browser can't detect a defect on its own — this is a visual aid for your own inspection.
What this test does
What we test: Whether the screen can render full-screen solid colors evenly, as a way to help you spot dead/stuck pixels, discoloration, or burn-in.
What you do: Look closely at each full-screen color panel for spots, lines, or tinted patches.
