Your problem
My problem is: every email has stats available about the type of devices that viewed it. These stats do not seem available in the reporting. Am I missing something?
Reports are run based on the fields in the customer data and some mautic functions . Unfortunately, Ive never seen device as a selectable field in custom reports. A workaround would be to build a segment by device type or whatever and use that as your base segment in the report buider. You could build a large aggregate segment by setting the segment equals filter and select all device segments you build.
