The British newspaper "The Sun" indicated that the green and yellow dots at the top of the front of the iPhone may represent a warning signal.
The newspaper said that the two points are an official alert from Apple, the maker of the iPhone, that the microphone or camera has been activated.
The alert was introduced in the update that Apple released for the operating system in 2020, where the two lights appear when the microphone or camera is turned on.
Thus, the importance of these two points is that if there is any application that surreptitiously records on the phone, the user will be able to know that through the two colors.
