Apple has version 15.4 of iOS released. From version 13, iOS is only suitable for the iPhone and the iPads have been given their own OS, with the main difference being the extra options to use the larger screen. In iOS 15, there are now four different types of notifications: passive, active, time sensitive, and critical. The second big new feature is Focus, a combination of Do Not Disturb and Auto Mode, along with new settings options. Furthermore, Facetime, Safari, Maps and Wallet have been provided with new functionality. Version 15.4 makes it possible, among other things, to use Face ID when you wear a mouth cap.
