Samsung positions the Galaxy S26 Ultra’s privacy around three layers: screen visibility, isolated on-device storage, and app-level data separation.
Privacy Display narrows viewing angles directly in the hardware, can switch on automatically for tasks like banking or PIN entry, and adds a maximum-protection mode without the brightness loss of third-party filters.
Knox and Knox Vault extend that protection below Android: Knox checks secure boot and monitors tampering, while the separate Vault stores passwords, biometrics, and encryption keys entirely on-device.
KEEP, Secure Folder, and Private Album split personal content into encrypted containers, while Auto Blocker can stop installs from outside the official app store at setup.
