While we’ve seen the removal of the iris scanner from the 2019 Samsung flagships, Google’s new Biometric API has been enabled by the latest Android 10 beta for the Galaxy S9 and Note 9.
You may have seen the beta program open in the US for the OneUI 2.0 build of Android 10 for those of you with a Galaxy S9 or Note 9 device. The iris scanner has gained the ability to be used in a wider range of apps that support Google’s Biometric API (via Android Police), according to some who have enlisted on Reddit.
Previously, it was only possible to use the iris scanner on the Galaxy S9 and Note 9 to unlock your device, Samsung Pay and the Knox Secure folder. This update means you can now use biometric data to secure and unlock Google Biometric API-supporting apps such as LastPass, Google Pay, and a few banking apps.
Adding the Google Biometrics API to both Android 10 builds for Galaxy S9 and Note 9 is a huge bonus, but it’s unlikely that those with the Galaxy S8 and Note 8 will ever be able to use their own iris scanners for anything more than they do at the moment— because Android 10 won’t get to either device.
Consequently, the iris scanner on both phones has become infinitely more useful than in the past. So if you haven’t set up iris scanning on your Galaxy S9 or Note 9, it might be time to do that now.
You will need to go to Settings> Lock screen and security> Iris Scanner and follow the on-screen instructions to enable iris scanning and record your own eye biometrics.
