The OP said the following yesterday.
"Just got my X a few hours ago and I have to say that it's incredible. By far the best phone ever made, I'm astonished on just how great the iPhone X is. It's a phone worthy of Steve Jobs, if Steve were here today he would be proud. GOOD JOB Apple, you have done it again!"
Ya, that was before it got dark out.. Funny how a device can go from the best thing ever to fundamentally flawed overnight. I'll bet OP is afraid of the dark..
My space grey phone in a black case disappears at night completely. I thought that was the DND feature. Huh..
