Leaked case images show the Samsung Galaxy S8's slim bezel screen, which is not a detail that hasn't already leaked before, but it does lend further evidence to the rumors that Samsung has changed things up with the Galaxy S8 by removing the physical hardware button that sits on the front of past Galaxy devices, which served as a home button and a fingerprint sensor. In these case images, it is clearly visible that there is no physical hardware button on the front where it would normally be, and also absent is the fingerprint sensor. What is on the front though is a rather large display with plenty of screen real estate, as well as the front-facing camera at the top end with the earpiece and ambient light sensors.
The fingerprint sensor however, is situated on the back as described in past rumors and shown in past leaks. It's visible to the right of the rear-facing camera, with the LED flash and heart rate sensor module to the left. With the cases on the phone in these images you can't exactly make out the entirety of the phone's design, but you can pick out the most noticeable changes to it that Samsung has seemingly made. With that said, the front of the device does also match up with a recent leak of what is said to be tempered glass screen protectors for the Galaxy S8, which also have holes for the camera, earpiece, and ambient light sensors on the front in the same spots.
Another recent leak showcased the branding for the Galaxy S8+ which is to be the larger version of the Galaxy S8 this year, and will be what the Galaxy S7 Edge was to the Galaxy S7 last year, as both flagship variants are rumored to have a curved edge screen this time around. Samsung was initially thought to be unveiling the Galaxy S8 at Mobile World Congress, but they have already confirmed that they will not be showing off the phone at the event, and instead will announce it officially at a later date, which is suspected to be at the end of March.
