This update includes improved support for Android 10 (SDK 29) and AndroidX, introducing features like Face Unlock and Iris Unlock, alongside existing iOS Face ID functionality. It addresses the critical challenge of securing mobile devices, which are integral to daily life but pose significant security risks when compromised.
