Today the "Browsers" report, classifies mobile devices as "None".
Displaying "None" even when a User-Agent is clearly captured, represents a confusing and misleading end-user experience.
If anything, this behavior only breeds mistrust of all reported data.
At a minimum, the "Browsers" report should behave similar to the "Browsers Type" report by presenting an "Other".
None should be reserved for the instances where the user-agent is unavailable, obscure, or otherwise not reasonably classifiable.
