Lenovo has issued a third firmware update for the Z6 Pro in China and this one puts the emphasis on the camera.
The firmware, ZUI 11.0.542, adds dual-view Vlog mode that allows video capture from the front and rear cameras simultaneously. Macro mode is now smart enough to switch on automatically, you can record video with variable speed with the wide angle camera. There will also be support for lock screen flash.
There are a number of bug fixes and optimizations in the update as well. Because the Lenovo Z6 Pro is China-only for now the firmware update is also China-only.
