The much leaked ZTE Axon M (codenamed Multy) has finally become official today. You can call this a flip smartphone, or a foldable one like its maker would like you to. This isn't foldable like in those tech dreams where the screen of the handset folds - instead, what we have here is a two-screen phone with a hinge in between.
When it's folded, the Axon M has a display on either side. When you unfold it, you get a total viewing area of 6.75", but the bezels don't help create the illusion that you're looking at one screen and not two.
