The message flash on an iPhone occurs when you have text message alerts enabled on the device, and you have also enabled another setting that causes the camera flash to trigger when an alert occurs. This is a popular configuration on the iPhone 7 because it is very eye-catching, can be easier to notice when compared to a vibration or a sound, and it’s just kind of a neat effect if not a lot of other people you know are using it.
