THE FUSE

If you have a Samsung phone, you might have wondered at one time or another why a green dot periodically shows up at the top right corner of your screen. I know I had. Don't worry, it's not a bug or in any way connected to the green line issue that sometimes affects Samsung and Apple devices. In fact, it's a security feature that lets you know if you've opened an app that's accessing your camera or your microphone. If you didn't fire up an application that's supposed to use your camera and mic, that's when the green dot appearing becomes a cause for worry.
