If you suddenly notice a small green dot in the upper-right corner of your Android phone, there is usually no reason to panic. The indicator is a privacy feature that alerts you when an app is accessing your device’s camera or microphone. It is designed to make this activity visible rather than allowing it to happen unnoticed.

The green dot may appear when you take a photo, record audio, make a video call, or use an app that requires camera or microphone access. On many Android devices, including Samsung phones, the feature helps users understand when sensitive hardware is being used and gives them greater control over app permissions.

If the dot appears unexpectedly, swipe down from the top of your screen and tap the privacy indicator. Your phone should identify whether the camera or microphone is active and show which app is responsible. If you recognize the application, the activity may simply be related to a permission you previously approved.

If an unfamiliar app appears, review its permissions through Settings > Privacy or Permission Manager, depending on your device. You can revoke camera or microphone access when it is unnecessary. Ultimately, the green dot is there to protect your privacy, giving you a quick way to see when your phone’s camera or microphone is being accessed.
