In our App we\'re using FCM, so Firebase analytics is also working. However, from the dashboard, we can only see top devices.
Is there a way to see more detai
There is one way to see the list of devices and OS. In the screenshot you uploaded, click on the Add Filter -> User Property -> {Device Model, Device Brand, App Version, OS Version etc.}
will be listed there.
If you have not specified any User Properties your self then also, firebase is Automatically collected user properties. Check the list of properties automatically collected by firebase.

Note: If firebase has collected any of the properties itself you will as I mentioned above.
Good luck!!
