Android's Green Dot Surfaces Hidden Camera and Microphone Access

A small green indicator at the top of Samsung Android devices signals active camera or microphone use in real time. Part of Android's system-level privacy layer since 2021, the dot cannot be suppressed by apps themselves. Tapping the notification shade reveals which application holds the session and permits immediate revocation. For personal and BYOD devices, it closes a gap left by permission-based controls alone—recurring audit signals rather than one-time grants.
