The flower icon on your camera indicates that macro mode is enabled, which is a feature that allows you to take close-up photos of small objects such as flowers and insects. When you get close enough to an object, the flower icon will appear in the camera app, and you can tap it to enable or disable macro mode. Macro mode helps to capture nearby objects more clearly, but tapping on the flower icon disables macro mode, turning your close-up photo blurry. To disable macro mode, you can tap on the flower icon again or turn off the Macro Control feature in your camera settings.
