Hi, because this is on a mobile (I assume 'phone') and I assume being displayed via a web browser then why not set a shortcut on the mobile device that specifically uses the tab?
http://localhost:1880/ui/#!/5 specifically forces the Dashboard UI to start displaying at the 6th tab (ordinal value). Tabs start at '0'. You can even setup a timer and, using the ui_control, cycle between several different dashboards every n seconds.
Cheers,
Paul
