I am use piwik API in my application and need to show the number of mobile users in proportion to desktop users. For this purpose i m use Live.getLastVisitsDetails API method and filter data by the field ‘screenType’. But the problem is that every record in API response contains field screenTye=‘mobile’ although browsers and OS are not mobile (Windows 7, Firefox and so on). Can anybody help me with this problem? Can be this because of some wrong piwik installation or i need something do to track mobile clients or something else?
