This 8-second video reveals our first real look at the Samsung Galaxy S8

Samsung is set to announce the new Galaxy S8 at its March 29 event, but it looks like someone's already got their hands on a working unit a little early.

The short video was posted on Slashleaks' YouTube channel, and it shows some of the main rumored changes that Samsung is making to its upcoming Galaxy S smartphone. 

Check it out:

Assuming the video is legitimate — and we believe it is — this is what the Galaxy S8 looks like:

There's a mysterious on-screen button that appears when the screen turns on, which could be Samsung's new 'Bixby' smart digital assistant, similar to Apple's Siri.

Samsung says you'll be able to control the Galaxy S8 using just your voice with Bixby. 

The user in the video does say something in the video, but it's not clear whether he's issuing any commands to Bixby.

As the rumors suggest, the display on the Galaxy S8 seems to have rounder corners compared to the square corners on previous models.

It also looks like it comes with a huge number of apps, but there's no way of telling whether the user added his own apps from the Google Play Store or Samsung App store, or if it's a ton of extra apps pre-installed to the device, called "bloatware."
