Privacy is always the main concern for smartphone manufacturers and Apple just added a pretty neat addition to iOS 14 at WWDC 2020. It all starts with permissions and then how these permissions are used later on. However, privacy is a great deal for Apple and it wants to keep everything completely transparent with the end-user. To do that, Apple is adding a new privacy feature in iOS 14 which will allow users to know when an app is using your device's microphone or camera.

Apple is adding orange and green indicators in iOS 14 which will let users know when an app is using your iPhone's microphone or camera for enhanced privacy. The orange and green indicator will be displayed on the top right-hand corner of the display above the signal strength. The orange dot represents when the microphone is being used. The green dot, on the other hand, tells you when the front or rear camera is being used.
