Note that Samsung is also developing a hole-punch design, which it calls the Infinity-O display, for its next generation of phones, including the forthcoming Galaxy S10. Lenovo may use a similar O-shaped cutout on its rumored Z5S.

For now, the Nova 4 is on sale exclusively in Asia, but the company plans to unveil it in the US in January at CES 2019.
