We haven’t even entered the start of 2020, and there are already reports surrounding the Galaxy Note 11 camera hardware. To refresh your memory, both the Galaxy S10 and Galaxy Note 10 family allow authentication using an in-screen fingerprint reader. However, next year could see Samsung adopt a wide range of technologies for its mobile handsets, including a ‘touchless’ and secure way to gain access to the home screen.

A fresh report from DigiTimes states that Samsung’s reportedly mulling over using ToF 3D sensing technology for the Galaxy Note 11 camera. It’s possible the Korean giant doesn’t want to employ the use of an in-screen fingerprint sensor thanks to a myriad of security issues reported earlier. It’s clear Samsung wants a more advanced way for users to authenticate themselves, which also suggests that in addition to gain access to the home screen, users may also use the feature to access apps and make payments using their face data.
