> Samsung already has live translation, including in calls.

Samsung isn't large enough to be considered a gatekeeper under the DMA. They're exempt from the rules Google and Apple have to follow.

Also I believe Samsung's in-person live translation feature is tied to their Galaxy earbuds hardware. This would be non-compliant if they were classified a gatekeeper.

If Samsung suddenly had to follow the same rules Apple does they'd either have to open up the API or pull this feature from the EU.
