The latest Android 15 beta hints at a feature that will automatically delete poorly performing face or fingerprint unlock models and prompt users to set them up again. This proactive approach aims to address issues with biometric authentication on Android devices, which can vary in accuracy due to different sensor technologies and environmental conditions. While the exact criteria for determining when a biometric isn't working well remains unclear, the upcoming Android 15 release could provide users with a more seamless experience by managing these issues automatically. Google is expected to release the third beta of Android 15 soon, with potential improvements in biometric authentication through automatic model deletion and re-enrollment. Stay tuned for updates on this feature as Android continues to enhance security and user experience.
