We've seen a lot of subtle design changes take place in the smartphone space over the years. Bezels kept getting smaller, leaving less space for front camera hardware. And then in 2018, we saw the hideous display notch make its debut. 2019, on the other hand, had a more sane approach towards maximizing screen real estate. Enter the hole-punch design that eliminated the notch by punching a hole in the screen and placing a camera sensor there. It appears that Vivo has taken that to another level, based on its recent patent filing.
