Autocorrect is annoying enough when it’s adding unwanted exclamation points and telling you that your name is misspelled. But some iPhone users have recently encountered the extra challenge of not being able to type the capital letter “I” with their keyboards. According to MacRumors, the autocorrect glitch is plaguing iPhone 7 and iPhone 7 Plus owners using iOS 11.0.3 and 11.1.

When users with the bug tried typing “I” with their keyboards, the letter ”A” followed by the character “[?]” show up in the predictive text bar. This seemingly random suggestion automatically inserts itself where the “I” should be. As you can see from Mental Floss Editor-in-Chief Erin McCarthy’s screenshots below, the bug isn’t limited to the Messages app.

The details surrounding the rogue autocorrect issue remain unclear. It doesn’t seem to be affecting all iPhone 7 owners with up-to-date operating systems, and some people who are reporting it say they see it popping up on Macs as well.

Until Apple comes up with a real solution, the company’s support staff is recommending users rely on text replacement as a quick workaround. You can do this on your phone by visiting the Settings pages, going to General, then Keyboard, and selecting the Text Replacement option. From there, type an uppercase “I” and elect to have it replaced with a lowercase “i” whenever you type it. (And while you’re in there you might as well tell your phone to stop replacing “omw" with “On my way!”)
