How far can you go to make your smartphone paper-thin? Or rather, how far should you go? Despite the recent #bendgate scandal that has seen many a phone deformed, Chinese manufacturer Vivo seems to be still hellbent on retaining its crown of "world's thinnest smartphone", no matter the cost. Well, it might have pretty much bagged that title with its upcoming X5 Max expected to be announced next month. This boasts of a profile that is absurdly only 4.75 mm thin, but with a screen size of 5.5 inches.
