Back in early 2009, Samsung unveiled a working foldable display at CES. Unfortunately, they did not push that technology into mass production yet, but various patents showing devices that take advantage of it continued to surface from time to time. Now, we get more than just a foldable display, since Samsung added multiple biometric authentication methods to the equation as well.
Although Samsung's foldable smartphone, known as Project Valley, is expected to come out by the end of 2017 and we might even see it show up in the first part of the year, the details are still shady. The latest Samsung patent spotted by Patently Mobile shows that the upcoming handset (or maybe one similar handset scheduled for a later launch) might use a fingerprint reader and an iris scanner. Even more, Samsung might use various other forms of biometric ID, including voice, palm print/line, or full face scans.
The current rumors claim that Samsung is working on two foldable smartphone models already, one with a single flexible display, and the other using a dual-display setup. Remains to see when will they finally manage to hit the market and how will they be received by the masses.
