A (relatively) huge white speck of dust just appeared on my iPhone 6S screen. Lower left, above headphone jack, over the phone icon. It's black on a white screen, and pure white on a black screen and when the phone is powered off. These new 6S screens are obviously not sealed! I've never had a situation where dust was able to get in an iPhone months after purchase. It's always been an issue out of the box and if its fine then you used to be able to breathe easy. Not anymore! This is definitely in front of the screen but under the first layer of glass. I thought this was impossible. I've babied the thing since September. Anyhow taking it to Genius Bar on Sunday. So frustrated. Thanks for letting me vent.
