Post process exposure dont work in some mobile devices.

hi guys, i have a rather important problem.
I have two high-end devices.
The first is a xiaomi mi10t, where everything works fine (both bloom and exposure work).

The second is a samsung galaxy S21, where as you can see, the exposure of the post processing volume does not work. Post processing seems to be there, because the bloom effect is visible, but the exposure doesn’t work.
I’ve tried every kind of exposure setting (auto, manual) but nothing changes.

At the moment I have been testing on 3 different devices.
3 of which have never had any problems.

Do you have any idea what the problem might be?

fixed by activating android vulkan support
