In any App that makes Use of Camera API 2 set ISO to manual-mode. Than try to set a value higher than 800.

Some Apps show higer ISO than, but there is no difference between images made with ISO 800, 1600 or 3200 at all. Only between 100 and 800 the value makes a visible difference.

I contacted the makers of FilmicPro and OpenCamera. They confirm, that this is an API 2 issue.

In Auto-Mode this Apps can reach much higher ISO without Problems.
