After updating to iOS 11.1, some iPhone and iPad users are seeing an issue related to autocorrect. When a user attempts to tap on the lowercase letter ‘i’. the autocorrect replaces the word with the letter ‘A’ followed by a question mark symbol. Apple has taken note of the matter and has devised a workaround fix for users who are experiencing it on their iPhone or iPad. In addition to this, Apple will also release a new iOS update which would carry the fix to the issue. So let’s dive in to see some more details on the upcoming update as well as the workaround fix.

As we have mentioned earlier, the issue revolves around the autocorrect input and it is yet unclear why is it affecting some iOS users rather than all of them. It began after users updated their iPhone or iPad to iOS 11.1. Nonetheless, Apple in its support document has mentioned that a future iOS update will fix the issue for once and for all. The gap between now and the time Apple releases an update is unknown, so until then you can try a workaround fix in order to continue texting on your iPhone.
