Apple has just released iOS 11.1.1 for the iPhone and iPad. You can download the software over-the-air by going to Settings > General > Software Update or through iTunes.
One of the changes in the software is a fix for an annoying autocorrect bug that had been plaguing iOS users with iOS 11.1.
The issue occurred when typing the letter “i” on the standard iOS keyboard. Instead of seeing an “i” you’ll see the keyboard autocorrect to the letter “A” with a symbol.
Another fix in the update deals with situations where they “Hey Siri” command stops working.
