Keep scroll position on mobile app when going back to page from detail view

PROBLEM:

Currently, when viewing the details of a data item in the mobile app, if the user presses the back button and returns to the page where the widget displays, the user always returns to the top of the page. So, if they have scrolled down the page a lot to find the data they are looking for, they will then have to scroll again to return back to that data. This is a usability problem and results in less efficent navigation for the user.
