Well, that will happen sooner than you may expect. vivo is holding an event in Shanghai, China on June 12, during which we assume it will introduce us to the market-ready version of the Apex. This assumption comes from the promo materials the company has sent us, which clearly depict a smartphone that looks very much like the Apex concept, complete with periscope selfie camera.
What's more, the company itself mentioned during its MWC event that the Apex will enter mass production sometime in mid-2018, and the timeline fits.
The Apex concept has 1.8mm side bezels and a 4.3mm chin. With that in mind, it's the closest any handset has been to the 'bezel-less' dream. The screen is a 5.99-inch Full HD+ OLED, and there's an under-display fingerprint sensor too.
