Samsung Electronics has announced a new privacy layer for Galaxy smartphones aimed at reducing shoulder surfing in public spaces. The feature focuses on controlling what people nearby can see on a phone screen when users are travelling, waiting in queues, or using devices in crowded environments. The company says the system has been developed over several years and will be introduced on upcoming Galaxy devices.

What problem the new Galaxy privacy layer addresses

Smartphones are frequently used in public places, often exposing messages, passwords, and notifications to unintended viewers. As phones become more personalised, the amount of sensitive information displayed on screen has increased. Samsung’s new privacy layer is designed to reduce this exposure by limiting screen visibility based on context and user preferences, without fully blocking access for the device owner.

How the new privacy layer works

The new Galaxy privacy layer combines hardware and software controls to manage screen visibility at a pixel level. When enabled, it can obscure PINs and passwords during entry, restrict what others can see while apps are open, and reduce the visibility of notification pop-ups. The system is designed to operate automatically once configured, allowing users to interact with their phones normally while limiting what is visible from side angles or nearby viewpoints.

Customisation and app-level controls

Samsung says the feature is not applied uniformly across the device. Users can choose which apps require additional privacy protection and decide whether the feature should activate during specific actions, such as entering passwords or viewing sensitive content. Notification visibility can also be adjusted, allowing alerts to appear in a limited or masked form when the phone detects public usage.

Security foundations behind the feature

The new privacy layer builds on Samsung’s existing security framework, including Samsung Knox, Knox Vault, and Knox Matrix. Samsung positions the feature as an extension of its security architecture, focusing on visual privacy rather than data protection alone.

Availability and rollout expectations

Samsung has not confirmed specific devices or timelines but says the privacy layer will arrive on Galaxy smartphones “very soon.” More details on supported models and settings are expected closer to the rollout.
