My galaxy S5 has been having issues with the companion app latley. When I open a thread and wish to return to the main forum I used to be able to simply hit the back button on my phone. Latley, however, the companion app has decided that when I press the back button on my phone it will.randomly go back to a previously visited page. It will jump to notifications, groups, messages, a previous forum or thread but it will not take me back to the forum I was just viewing. This seems to apply with the forums and group forums as well. Just thought id post this issue and see if it needs fixing.
This is how it's always worked. If you're viewing a thread and you click a link to take you to view another thread, upon select "back" it's going to return you inside the original thread. The easiest way to think is it's not a "web browser" in the traditional sense, it's an app that will take you directly back to what you were viewing previously.
