Apple planning over-the-air OS recovery for iOS devices
The third beta version of iOS 13.4 reveals the existence of a new feature called "OS Recovery", which is quite suggestive. As best we can tell, it looks like a new way to restore an iPhone, iPad, and other Apple devices without the need to connect them to a computer. It's not yet possible to access it in the system as the feature is still under development and it could be scrapped at any time.
According to what we found in the system, it would be possible to restore the iOS directly over-the-air as well as by connecting the device via USB to another iPhone or iPad, similar to how Apple's Migration Tool works.
This seems like one of those things that should've been the default for years now on both iOS and Android - so much so that I had to stop and think twice just to remember it isn't, yet.
