In Strategy Mobile 9.3.x and above, there is a way to render the report service document fit to page or width to make the document uniform across different Android devices.
1. In Strategy Web, open the document in design mode,go to document properties > Mobile, check on "Optimize layout for micro applications".

2. Run the document in interactive mode(or express, editable,flash mode). Zoom the layout to fit to page/width. Save the document.
3. Run the document in Strategy Mobile on Android. The document is fit to page/width.
This option only respects to Android.
