    Hello, I bought an iPhone 6s Plus. I was checking dead pixel via:

    On Portrait mode, I see brown-read across the screen but when I rotated the phone by 90 degrees to landscape model, I see lots of square boxes like a tartan. Is this normal?

    What is the best way to check for dead pixel? Thanks

    If you can't see a dead pixel then does it matter?
    Select a solid colour like white or gray. Any pixels should show. Despite posts to the contrary much rarer than you think.
