问题
On the Firebase Analytics Dashboard they display summary data for device and OS breakdown but it does not show the complete breakdown (in my case meaning I can't view the breakdown for 44.7% of my user base). Is there anywhere in Firebase I can either view this information or export it to view it somewhere else?

It's a bit tedious, but you can add a filter on the dashboard to see the usage numbers for each device and each iOS version. Click Filters → User Property → Device Model or Filters → User Property → OS Version to filter to a single device or OS.
If you record or export the numbers for each device and OS, you can work out the percentage distribution.

With the new version of Firebase, you can see it by putting your mouse over the other section:

You can also export a CSVwith a breakdown of the devices. It is available from the Dashboard on the menu in upper-right.
