There is a internal list with the UserAgents and the DeviceModels, which contains the information needed by the Device Detection Framework. As I have mentioned, I will forward this to our developers, so they could update those lists accordingly.
As for the GetScreenSize approach, you have mentioned in one of your previous posts that this approach works and allows you to change the views of the RadCalendar, which is why I suggested that you keep using this approach.
Please excuse us for any inconvenience caused by this.
