The Samsung Galaxy S8 is impatient - its official debut is on March 29, but the flagship frequently visits the rumor mill. In another short video, the S8 shows off its fingerprint reader. It relocated from the front (which no longer has a front button) to the back, very near the camera. There's a good chance that you'll smudge the camera when you unlock the phone, which isn't ideal. Initially, the fingerprint reader was meant to be under the screen, but (allegedly) the engineers ran out of time. Have a look at the lockscreen at the beginning of the video - is it just us or does that...
