Samsung One UI 8 Based on Android 16 Brings Major Privacy Upgrades with KEEP and Post-Quantum Security

Samsung has officially unveiled One UI 8, built on Android 16, and it's packed with a powerful new suite of security and privacy features. The announcement strongly suggests that the Galaxy Z Fold7 and Flip7 will be the first devices to debut with this new software version pre-installed.

Meet KEEP: Knox Enhanced Encrypted Protection

A major highlight in One UI 8 is the introduction of KEEP (Knox Enhanced Encrypted Protection). This new tech creates encrypted, app-specific storage environments inside your phone’s secure storage, ensuring that each app only accesses its own sensitive data—nothing more.

KEEP is designed to safeguard your personal insights like app usage patterns, preferences, and routines. These insights power features such as:

Now Brief

Smart Gallery Search

Samsung Moments

Smart Suggestions

All of these run on-device, without compromising your privacy, thanks to KEEP and the Knox Vault hardware security layer.

Next-Level Account and Network Protection

Samsung is also introducing automatic account sign-outs for devices flagged under “serious risk” (like system tampering or identity spoofing). This action prevents compromised devices from accessing cloud-connected services, and notifies users across all linked Galaxy devices for real-time awareness.

On the network front, Secure Wi-Fi now supports post-quantum cryptography, making Samsung one of the first smartphone makers to prepare for the next generation of quantum-resistant cybersecurity. This means your encrypted data stays secure—even against future threats capable of breaking today’s encryption standards.

Final Thoughts

With One UI 8, Samsung is doubling down on on-device AI, user data privacy, and future-proof network security, setting a new standard for Android-based ecosystems.
