For now, what are we all waiting for? iOS 9, which should be released together with iPhone 6s, Apple is currently testing iOS 9.1, as engineers from Applu visit the server MacRumors, where astute editors noticed that a new system appeared in their statistics from which users access their website.
Phone access statistics with iOS 9.1 start on July 21st, a day later the attendance started to rise and peaked in the dozens until July 28th. In August, however, attendance from facilities with iOS 9.1 is minimal and only a few users visited the server about a week ago. MacRumors added that most of the accesses were from iPads Air or from iPad miniThen users accessed from a device that has the same screen size as iPhone 6 Plus. However, it is unclear whether the engineers accessed the site from current Apple device or, for example, from an iPhone 6s Plus and iPad mini 3.
It is not clear why Apple spent two weeks testing iOS 9.1, when he certainly has his hands full with iOS 9, but it could certainly be due to testing the iPad Pro or iPad mini 4, as both new tablets are expected to go into mass production soon. It's not even entirely certain what the update will include. iOS 9.1 to bring, but special features are being considered for iPad Pro with a 12,9″ diagonal, which could offer users new options when handling the system on the large display of the new iPad. That is why it is completely logical that iOS 9.1 will be released at the same time as the iPad Pro goes on sale sometime in November, as is customary with iPads.
