Devices might use different commands or accept different key presses to perform certain actions. Therefore a universal button configuration or UI screen layout would not work the same way.
Devices profiles are device specific configurations that contain default button mapping and UI configuration for a specific device.
These configurations are tested to make sure it works with the specific device.
For Android TV based streaming boxes and TV devices, try the generic Android profile if there's not a specific profile for your device.
Use the default profile if nothing else matches.
We will be adding more profiles.
Custom profiles can be uploaded with the API, a UI option will be provided in the future.
