Samsung left a fairly large gap between the release of its Galaxy Tab S2 and Tab S3 tablets, but it appears that the Korean electronics giant isn't resting on its laurels when it comes to the Galaxy Tab S4 launch — a listing believed to be the next iteration of Samsung's flagship tablet has shown up on the Federal Communications Commission (FCC) website (via Droid Life), just 16 months after the launch of its predecessor.

While the Galaxy Tab S4 isn't specifically listed by name, the device submitted to the FCC carries the model number SM-T835, which follows the same naming scheme as Samsung's previous tablets in the S series, including the Galaxy Tab S2 (SM-T810) and Tab S3 (SM-T825).
