Asus is still very much an also-ran in the smartphone world, but that gives it the space to try some unconventional designs that many find appealing. Take, for example, the Zenfone 6 and later, which elegantly solves the aesthetic issue of the notch by making its rear camera module flip around to the front when needed. Personally, I think it makes the Zenfone series some of the best-looking Android hardware there is. Asus isn't quite done with this design yet, according to a newly-leaked render of the unannounced ZenFone 8 Flip.
