A user agent profile (UAProf) from the Samsung Mobile server, has mentioned an unannounced Samsung device bearing model number SM-G890A.

The model number of SM-G890A matches with the SM-G870A, which is the AT&T variant of Galaxy S5 Active. And SM-G890A is expected to be the rugged version of the Galaxy S6 smartphone dubbed Galaxy S6 Active for AT&T.
