Switching between desktop and mobile on mobile

I use my phone most of the time. Sometimes I have to switch to desktop view to post a picture. When I switch back to mobile view I get taken to the home screen.

This is not a major issue. It's very minor. But it would be nice to stay on the thread I am looking at when I switch between mobile and desktop view.

I don't even know if that can be changed, but I'm just throwing the suggestion out there.
