The latest Google Camera update is now rolling out to Pixel phones, and it brings with it a 4K Video Toggle.
Say you only need a 1080p video, or you want to shoot at 60fps, you can't do that in 4K, so now you have the option to quickly switch to 1080p.
Since 4K can only shoot in 30FPS on Pixel phones, it's not needed when 4K is selected.
Remember that the Google Camera app can only be installed on Pixel smartphones, so if you're using a Galaxy S20 smartphone and want to install the Google Camera, you can't.
But Google is sticking with its stance that it takes up to much storage to shoot 4K in 60 frames-per-second.
