Samsung and WhatsApp are rolling out new security features aimed at reducing everyday privacy risks, including shoulder surfing in public places and cyber attacks targeting user accounts.
Samsung said it will introduce a new privacy layer for Galaxy devices that selectively hides sensitive on-screen content from side angles, while remaining visible to the user. The feature, developed over more than five years, can protect specific areas such as message notifications or passcode entry fields and builds on the company’s Knox security platform.
WhatsApp has also launched a new “Strict Account Settings” mode that groups multiple protections behind a single switch. When enabled, it blocks media and messages from unknown senders, disables link previews, restricts who can add users to groups, and turns on two-step verification and security alerts by default.
For businesses, the updates highlight the importance of reducing simple exposure risks by limiting what can be seen in public, tightening controls on unknown contacts, and enforcing strong default security settings across devices and messaging platforms.
