iPhone 5S Dead Pixels Issue

[pepelino224]

I've heard that many iPhones came out from China with at least 1 or 2 dead pixels, check your screen on full brightness with white wallpaper, i replaced 3 models and all of them same, every year has to be something wrong! Damn!

There is not a single company on the planet that can produce a 100% yield rate LCD panel. Doesn't exist.
