  • Samsung has filed a patent for a foldable phone with a double-sided in-display fingerprint sensor.
  • This would enable fingerprint unlocking via both screens on a Galaxy Fold-style device.

One of the more understated challenges with foldable phones is biometric unlocking, and we’ve seen almost all major devices adopt a side-mounted fingerprint scanner instead of an under-display sensor. Samsung has adopted a side scanner on its foldables too, but it looks like the company is hard at work on an alternative solution.

Let’s Go Digital has uncovered a Samsung patent filed with the World Intellectual Property Office (WIPO), detailing a dual-sided in-display fingerprint sensor for a Galaxy Z Fold-style foldable. Check out an image below, courtesy of the outlet.
