After owning my iPhone 6S+ since its launch, I have discovered a single dead pixel. Do these appear throughout the life of a display or will it have always been there? It's a constant black dot about 1cm from the top of the screen. And it is easily visible in almost every app thanks to its location. No idea how I haven't noticed it before! It's one tiny dot on an otherwise perfect screen, but the trouble is, it's all I can see now. (Yes first world problems) What are Apple like with these sort of issues? It seems so small that I'd probably be wasting my time as the Apple Store. Which is about a 2 hour drive away.
