The screenshot above is not from a devices, but from an emulator.
The Tizen SDK reports the browser's user agent as Samsung I9500. The interesting thing is not that Samsung is working on a Tizen phone, but that the I9xxx line is usually for their flagship Androids - I9000 Galaxy S, I9100 Galaxy S II, I9250 Galaxy Nexus. We've already heard of the I9500 as the Galaxy S III
