Samsung Galaxy S8 (rumor)
Samsung is reportedly working to put an optical
fingerprint scanner on the Galaxy S8 and it will help Samsung achieve a truly
full-screen device.
The optical fingerprint recognition is the oldest
tech, preceding the capacitive and ultrasonic solution currently used in modern
devices. It is bulkier due to its need to illuminate the surface and relies on
a 2D image instead of a 3D one (as is the case with Qualcomm's ultrasonic
tech).
Samsung may have found a way to use high-res optical
sensor under its smartphone displays, and in the meantime, shrink the needed
pieces to fit the Galaxy S8 shell. It is said to include such an optical
fingerprint recognition on its upcoming flagship and it may even ditch the
front keys altogether for a true full-screen smartphone (something Xiaomi is
trying to achieve with the Mi Mix).
Samsung is reportedly having some hiccups with the
components for the optical fingerprint recognition, but the Galaxy S8 is still
half a year away so there is plenty of time to resolve the production issues.
