Realizing the Nex's expansive, almost bezel-free look naturally demanded slight changes in other design components. In this case, the earpiece speaker is moved into the screen, and Vivo opts for an third gen in-display fingerprint scanner which helps to conceal the sensor beneath the display. There's still a tiny chin at the bottom, but it's really minimal.
The jury's still out on overall efficacy -- our test provided mixed results -- but early owners will be able to determine whether the fingerprint tech has improved since then. Regardless, Vivo's attempts at developing in-display fingerprint readers has paved a path which other smartphone makers are likely to follow.
Update: We now have hands-on pics that really show off that bezel-free experience, taken by our colleagues at Engadget Chinese at the Vivo NEX unveiling in Shanghai.
