Interesting list of so-called hidden features in iOS 12 from Zach Epstein:
iOS 12 is sort of like a turbocharged bug fix release for iOS 11. Sure there are plenty of new features to be found, but the real story in iOS 12 is that it completely fixes the mess created by iOS 11.
Where’s the math to prove iOS 11 had more bugs than any other release?
The past year has been filled with bugs, security holes, and all sort of problems with iOS 11 that really held back Apple’s new iPhone lineup.
Whatever techies think was the problem does not seem to have had an impact on sales. Just before iOS 12 was released, Apple’s customers had upgraded to iOS 11 to the tune of just under 90-percent of the installed base.
