That's right, it's the iPhone, but it's not all right, because Trump used two phones together, an iPhone was specifically designed to answer calls, and another iPhone made him send Twitter, browse web pages, etc. (PS: Truly Twitter Rule the country...).
Of course, these two iPhones are not the same as those sold directly on the market because the mobile phones are provided by the White House Information Technology and the White House News Service. Therefore, the system must be carefully inspected. There should be no leakage of confidentiality.
It is reported that one of Trump's iPhones, which can only make telephone calls, can also take pictures in addition to the telephone function, and all other functions are blocked.
