I noticed when I Press the sleep wake button on my iPhone 6, instead of the screen turning on and going to the lock screen, the screen has a gradual flicker to white then black, then the lock screen comes up. pressing the button again turns the screen off, and pressing it again turns the screen on normally without flickering.

However after turning the screen off and waiting for about 5 minutes, then pressing the sleep/wake button, the screen gradually flickers to white, then black, then brings up the lock screen.

It's as if the phone when the screen is cooled down or off for an extended period of time, this behavior occurs. I notice it is most easily observed in a dark/pitch black environment.

Anyone else notice this or are you not seeing this? Is this an issue?

I noticed the same problem

About five days ago I noticed my iPhone 6 was doing the same thing. Did you ever find out what was causing it? Did you speak with Apple?

I have seen this a couple of times with different devices. Iphone 4S and iPad 3rd and 4th gen. All seemingly random and never seen again.
