AT&T's being all coy about it, but it's pretty clear the phone in its latest teaser trailer is the Samsung Galaxy S4 Active. The ruggedized, water-resistant version of Samsung's flagship was announced last week, and will be on show at the company's Premiere 2013 event in London next Thursday. Meanwhile, AT&T's promising more info tomorrow, June 13.

Check out the video above -- and note the Active's trademark button setup at 0:11, and the TouchWiz UI towards the end. We'll be live from London on the 20th to bring you full coverage of the Galaxy S4 Active.
