Samsung has long been rumored to be working on an in-screen fingerprint scanner and a recently published patent suggests it’s not given up on the idea.
Filed with the World Intellectual Property Organization (WIPO) and spotted by TechTastic, the patent shows a handset with a fingerprint scanner built into the display, just above the bottom bezel.
