While there are still a lot of unknowns, the Z6 Pro will possibly stick to single camera setup, as suggested on a teaser, and the rest of the rumored features include HyperVision camera, Super Night View, Super Steady Shot, and a way to make 100-megapixel shots.
While the teaser clearly states it will be based on Qualcomm's flagship Snapdragon 855 SoC, earlier details also pointed to a possible 5G version as well as an under-display fingerprint scanner.
The teaser was posted over at Weibo by Lenovo's VP, and hopefully, we will hear more details about the Z6 Pro soon.
