Huawei Mate XS - Ultimate Foldable Smartphone?

A foldable that works as a proper flagship phone first, with a standout rear-camera selfie setup and the best Android multitasking he has seen, and battery that lasted a full day.

Mentioned as a contrast: the small front screen leaves you stuck when the phone is folded.

Last year's model, referenced for the improved opening mechanism and hinge on the Mate Xs.
