Huawei is one company that's experimented with alternatives to the traditional notch. The P20, introduced in March, lets you turn off the notch in the phone's settings. And the company has another phone with a hole-punch design in the works with the Honor View 20 -- which like the Nova 4, has a 48-megapixel camera -- scheduled to debut in China on Dec. 26 and globally on Jan. 22.

Samsung has its own hole-punch design, called the Infinity-O display. Rumored to appear on the forthcoming Galaxy S10, it's also in use on the Galaxy A8S. Lenovo may use a similar O-shaped cutout on its rumored Z5S.
