The flower icon on the iPhone camera indicates that Macro Mode is enabled, which allows users to take close-up photos of objects such as flowers and insects. When Macro Mode is enabled, the iPhone camera automatically switches from the Wide lens to the Ultra Wide lens when an object is placed within 5.5 inches of the rear camera. The viewfinder still shows "1x" framing, but the camera relies on the Ultra Wide lens for autofocus. The flower icon appears when the camera is close to an object to take macro photos and lets users easily switch between off and on without going into the Settings page. To turn on the option to see the toggle when taking close-up shots, users can follow these steps: launch the Settings app on the iPhone, scroll down and tap Camera, scroll down and toggle the switch next to Macro Control so that its in the green ON position.
