Vivo has announced a new flagship device called the Nex, a phone that the Chinese company claims “fulfills the bezel-less dream.” The Nex is based on Apex, the impressive concept we saw at Mobile World Congress in February. Like Apex, the Nex avoids the now-ubiquitous display notch by employing an elevating selfie camera that pops out from the top edge of the phone when required. This allows the Nex to achieve a screen-to-body ratio of 91.24 percent, Vivo says, though there is still a slight “chin” at the bottom of the screen.

Further contributing to the bezel-less effect is Vivo’s glass-vibrating “screen soundcasting technology,” which replaces the earpiece speaker and sounded pretty good in my experience with Apex. The Nex also uses an in-display fingerprint sensor, but unlike Apex it doesn’t cover a large area of the screen — it sounds like the implementation is similar to the X21, which we found to be impressive in practice despite only working over a thumbprint-sized area. Vivo does say that its “third-generation” sensor improves on speed, which was a slight caveat with the X21.
