Although the Galaxy S8 won't be at Mobile World Congress, it's expected to have an unveiling sometime in March. But that hasn't stopped the leaks from coming. Today, we have yet another drip of info about Samsung's upcoming flagship.

After showing off pictures with the screen off, Twitter user "Ice Universe" has some convincing pictures of the device with the screen on. They give us a great idea of just how slim the bezels are, and we can see the rounded display corners, just like the Xiaomi Mi Mix and the upcoming LG G6.

The Galaxy S8 will be the first Samsung phone with on-screen buttons, if you don't count the Samsung Galaxy Nexus, which was designed in collaboration with Google. So it's a shame that none of the pictures show the home screen with the full suite of buttons present. We can get an idea of what the buttons look like from a leaked post over at Android Police.

Android Police has tutorial artwork from a leaked Galaxy Tab S3 system image that apparently isn't from the Tab S3 (which still has hardware buttons). The tutorial image is actually for the Galaxy S8. The picture seems to demo the use of the heart rate sensor, but the important bit is a full showing of the on-screen navigation buttons.

The design of the buttons is pretty crazy and in line with Samsung's "change for the sake of change" attitude toward Android. The Home button is a square with one of the corners missing, while Back is an arrow with a chunk missing. Recent Apps looks like two opposite "L" shapes, which could be trying to indicate a stack of cards in this apparent "missing parts" style. The buttons are still in a backwards order from every other Android phone in existence, but since they're just pixels, hopefully you'll be able to swap the order.

The system image also shows the "DeX" dock for the Galaxy S8, which is an HDMI dock that turns the phone into a desktop computer.

We still have no official word on the exact date for the Galaxy S8 reveal, but it will be sometime after Mobile World Congress, which ends on March 2.
