Every new iPhone release means a new version of iOS, and that means even newer updates to smooth out rough edges and discard the 2019 crop of bugs. This year seems different. Zach Epstein:
[Apple] on Monday released a new update for the iPhone. iOS 13.1.2 comes just one business day after iOS 13.1.1, which was released on Friday.
Think about it. Less than two weeks ago we had iOS 13.0. Then, 13.1, then 13.1.1, and now 13.1.2. What got fixed?
It includes even more bug fixes like minor fixes for the camera app, iCloud backup, and more. None of the bugs that were fixed seem particularly urgent so we’re not sure why Apple had to release iOS 13.1.2 so soon after the last update, but it’s out and it has improvements so you might as well download it.
Interestingly, I have yet to experience one bug on the new iPhone.
