CNET's biggest problem with the Galaxy S8 and S8 Plus was the placement of the fingerprint reader on the back of the phones, which forces right-handed folks to reach across the camera to unlock the phone.

With the rumored Galaxy S9 and Galaxy S9+ phones, Samsung could reverse that, according to an early render from phone case maker Olixar, which was spotted through online retailer Mobile Fun.
