In the beta version of iOS 13, they mentioned a possible date for the presentation of the new Apple smartphone - September 10. In fact, it’s difficult to call it a surprise, since the American corporation shows “annual” mobile phones at about the same time with a few exceptions, when the schedule shifts by a couple of days.
The expected date - September 10 - differs from the previous two when Apple held the presentation of new devices on the 12th of the same month (usually this is the second Tuesday of September). The new calendar is indicated by the built-in calendar, more precisely a screenshot, on which the icon with the corresponding day is visible. This was noticed by iHelp BR resource browsers.
In comparison, iOS 12 had a similar story when Apple presented the iPhone XS.
Another set of screenshots shows the possible release date and iOS 13 - September 23. If Apple’s usual practice continues, sales of the new iPhone will start that day.
