So much for secrets.

Ahead of Samsung's Galaxy Note 7 announcement event on Aug. 2, we now have our first look at how the smartphone's iris scanner will work.

In a video posted to YouTube (and originally published on China's Weibo), we can see the phone detect a person's eyes and then instantly unlock the screen.

I had to rewatch it a couple of times because the eye detection happened so quickly.

As you can see in the video above, the lock screen will be split into two halves: the top for the iris scanner and the bottom for the regular pattern/PIN unlock half.

Users will also presumably be able to use a fingerprint sensor embedded in the home button to unlock the phone as they do on the Galaxy S7 and S7 Edge.

When it was first rumored that the Note 7 would come with an iris scanner, I said its success would depend on its responsiveness. A slow, inaccurate iris scanner would doom the feature to being a gimmick.

But if the phone's iris scanner is indeed as instantaneous as shown in this leaked video, Samsung could have a very compelling phone on its hand, especially now that people are more cognizant about protecting their personal data.

Rumored specs for the Note include a 5.7-inch Quad HD Super AMOLED display, Qualcomm Snapdragon 821 processor, 6GB of RAM, 64GB of storage, a microSD card slot, 12-megapixel rear camera, 5-megapixel front camera and IP68 dust and water resistance rating.

In recent weeks, we've seen the clearest images of the Note 7 in all its glory.

One thing that's still unclear is if the phone will have a flat screen or dual curved sides like the S7 Edge Plus. Leaked images have surfaced for both, but it's possible Samsung might just release one model.

Mashable will be reporting live from the Aug. 2 Samsung Unpacked event. We'll have full details on the Note 7 once it's officially announced.

Based on what we've seen from the leaks, though, the Note 7 looks like it'll be pretty sweet.
