I thought S9 will receive Night Mode too, will it? I just updated my phone yesterday, it was the second update of July after the first one at the beginning of July. And I still can't be able to find Night Mode in Camera. Will there be another update or something?

Are you positive that you installed the July security patch? Lots of community members were looking forward to the night mode option. I should be getting the July update in the next week or two so I'll let you know if I see the night mode option.
