Not trying to start a iOS vs. Android fight here. Please keep this civil. I do think the iPhone X is a great phone, with a fantastic display, great camera, and overall size is just about perfect, and the A11 chipset is amazing. But this super cool futuristic X phone just seems strange running this version of iOS, like it doesn't belong on the iPhone X, with iOS 11 it makes the X seems like it's running something from 5 years ago. In my opinion, the iPhone X should have gotten a refreshed UI from Apple.
