It’s pure, pristine, uninterrupted glass. And it takes up the entire front of the phone, flowing seamlessly into the aluminum shell. The result is a beautifully curved, perfectly symmetrical, singular object, and the camera is also competitive with other selfie ready smartphones with 12MP rear camera and the 8MP front camera, accurate and fast that you won't miss a moment, day or night. With its new technology that will allow the user to fully secure their data and other other personal files, the security feature of the Galaxy S8 is super crazy, crying eyes are not a problem when you have iris scanning on the Galaxy S8 and S8+. No two irises have the same pattern, not even yours, and they're nearly impossible to replicate. That means with iris scanning, your phone and its contents open to your eyes only. And when you need to unlock really fast, face recognition is a handy option.
