While the Galaxy S8 won't be announced at Mobile World Congress next week in Barcelona, the Galaxy Tab S3 appears to be headed there. And now there is a system dump floating around, from that device, which people are tearing apart to see what they can find about the new tablet. But Samsung has a bit of a surprise in that system dump. And that surprise includes a few features of the Galaxy S8 in plain sight. This includes things like the on-screen buttons, and the rear-mounted fingerprint sensor.
In the pictures below, you'll notice that Samsung is still using the back button on the right side of the home button. This is where Samsung has always had it, even though just about every other Android device has it on the other side. On the left of the home button is a new looking button, but it's simply a multi-tasking key. The home button looks a bit different, as it's a square instead of a circle, like most software keys use. The fingerprint sensor is indeed still on the back of the device, which has been the subject of plenty of talk in recent weeks. Not because the fingerprint sensor is on the back of the device – many flagships do that already – but the position it has on the back. The sensor is up next to the camera, and on a larger smartphone like the Galaxy S8 or Galaxy S8 Plus, that's going to be pretty tough to reach.
Android Police also notes in their piece that they have spoken with a source and was able to confirm DeX, which is basically Samsung's docking system, which allows you to use your phone as a desktop computer. It's something we've seen before, but it's never really worked out well. Supposedly DeX will flip open to dock your Galaxy S8 or Galaxy S8 Plus, and then that will connect to your monitor via a HDMI port on the backside. Of course, there is still plenty more to learn about DeX, but for now it seems pretty simple.
Everything here seems to line up perfectly with recent leaks and rumors about the Galaxy S8 and Galaxy S8 Plus, which isn't a huge surprise really. Given that we are this close to the thing launching, Samsung is already on their last prototype and likely mass producing it already. The two devices are expected to be unveiled at a separate event in March or April and be available shortly thereafter.
