If the listed app is something you recognize, there is generally nothing to worry about. The indicator is simply confirming that the application is using a sensor you have permitted it to access. For example, messaging, camera, recording, and video-call applications commonly require these permissions.
However, an unfamiliar application deserves closer attention. You can open Settings, find Privacy and Permission Manager, and review which applications have access to your camera and microphone. Permissions can be removed if an app no longer needs them or if you do not trust its access.
You can also choose to restrict permissions so an application can only use a sensor while it is actively being used. If an unfamiliar app has no legitimate reason to access your microphone or camera, uninstalling it may be the safest choice.
Ultimately, the green dot is meant to provide reassurance rather than fear. It gives you visibility into what your phone is doing and allows you to investigate unexpected activity. Once understood, this tiny indicator becomes an important privacy safeguard that helps keep control of your camera, microphone, and personal information in your hands.
