A useful feature of the Devices report is the ability to view your traffic by operating system (OS).
To find this data, start by visiting the Devices menu.
Next, click the Device Type dropdown above the data table and select OS.
In the data table, you’ll now see how many visitors your site gets by operating system.
In addition to seeing the number of visitors each OS has, make sure to check out the traffic share and compare each OS by engagement metrics too, like session duration and bounce rate.
