Android 16 is set to bring enhanced security features to users, primarily through the integration of Google's Advanced Protection mode. This initiative aims to provide robust defenses against sophisticated online threats, malware, and data breaches, ensuring a safer mobile experience for all users, especially those at high risk.

The Advanced Protection Program (APP) has been around for some time, initially offering protection against Google Account attacks. Now, with Android 16, Google is extending security hardening to the mobile device itself. This device-level security layer bundles Android’s strongest system-level security features and prevents the disabling of individual security features, whether maliciously or accidentally.

Advanced Protection in Android 16 is designed to be simple to activate. It consolidates Android's highest security features into a single system. Once enabled, it ensures that all of Android's top-tier security features work together seamlessly to protect against online attacks, harmful apps, and data risks. This includes features like verified boot and runtime integrity checks, strong sandboxing, USB port lockdown, app isolation, and enhanced Google Play Protect scanning. Several of the features that would soon be consolidated within Advanced Protection have been safeguarding Android users for a while now. At the same time, other features like Spam and Scam Protection, Theft Detection, Offline Device Lock, and Automatic Call Screening are recent additions to Google's suite of security and privacy-focused features. Alternatively, features like Intrusion Detection/Logging, Inactivity Reboot, USB Protection, and the automatic setting to disable auto-reconnects to insecure networks are all new features posed to debut with Android 16.

One of the key components of the Advanced Protection mode is Intrusion Logging. This innovative feature securely backs up device logs in a privacy-preserving and tamper-resistant manner, accessible only to the user, and enables forensic analysis if a device compromise is suspected. Furthermore, Advanced Protection includes USB protection, which restricts new USB connections to charging only by default when the device is locked, protecting against physical attacks. There is also the option to disable auto-reconnect to insecure networks.

Android 16 also brings enhanced protection against phone call scams. It blocks risky actions during calls from unknown numbers, such as sideloading apps, granting accessibility permissions, or disabling Play Protect. If a user is screen sharing during a call, Android will automatically prompt them to stop sharing at the end of the call.

In addition to Advanced Protection, Android 16 includes improvements to Google Play Protect. Google Play Protect now uses a new set of on-device rules to specifically look for text or binary patterns to quickly identify malware families. If an app shows these malicious patterns, the system can alert the user before they even install it.

Scam Detection in Google Messages is also enhanced. The AI-powered Scam Detection feature can detect suspicious conversation patterns that might lead to scams. The feature works on-device, warning users about various potential scams, including package delivery, job-seeking, crypto, and tech support scams.

The Find My Device network receives a revamp, and anti-theft features are updated. Devices running Android 16 get tougher factory reset protections and better controls over Remote Lock. A security challenge question can be added to prevent unauthorized actions. Furthermore, Google's Identity Check security feature expands to a broader range of Android smartphones with the Android 16 release. This feature enforces biometric-only authentication for high-risk actions, requiring fingerprint or facial recognition before users can perform critical actions, especially when the device is outside of pre-defined “trusted locations”.

These comprehensive updates in Android 16 reflect Google's ongoing commitment to user security and privacy. By consolidating and enhancing various security features, Android 16 aims to provide a safer and more secure mobile experience, protecting users from a wide range of threats.
