Google is rolling out a new protection system called Google Play Protect, it is a machine-learning system to protect Android users. Google implements a machine learning and app usage analysis to identify any malicious activity on the mobile device. The system is integrated into the Google Play Store app, this means that its usage is transparent to the end user that doesnt need to install or enable it on his device. Google also implements Anti-Theft Measures, the Android Device Manager has been replaced with Find My Device, that allows users to locate lost and misplaced devices.”]
