Instructions to turn on iPhone screen flash

iOS 26.2 introduces a new feature that displays a screen warning light to let users know. Unlike Android, which has a notification light , the iPhone does not have a notification LED when you receive a call, message, or other alert. But when you update to iOS 26.2, you can choose both the screen LED and the camera LED to flash when there is a new notification. Here are instructions to turn on the iPhone screen warning light.
