The facial recognition feature has been incorporated in Android already but it was not as protected and secured in the past years. The Isis scanners have contributed a lot in making the technology secure and protected. It seems like Google is adding up the official support for Iris scanners now.
Samsung’s Galaxy Note 7 was the pioneer in bringing this idea to the market by making its integration felt less than the expected. We may expect it will gain the official support of biometric authentication for the Android future version. To achieve this objective, the software engineers of Fingerprint Cards are already doing this job. There are possibilities that they would sell their own hardware.
Currently, they are developing an internal design and structure to make it easier for OEM to incorporate this feature.
We expect Google to say something in this regard before it actually gets merged into AOSP or even an Android future version, what we’re seeing is surely positive. Remember not to expect the tech in Android P.
