Apple is fixing one of the most troublesome problems that have faced iPhone phones.

Users were unable to write the letter “I” on their phones, where the iPhone device corrects the letter and write “A”, and no one knows why.

This phenomenon was spread over the Internet, as it was not possible to write one of the most common characters in English.

The problem spread very quickly, such as the virus, and the causes are still unclear so far.

Apple introduced the software update to fix the problem. IOS 11.1.1 launched just days after the iOS 11.1 system update, enables the problem to be fixed, according to Apple.

The problem was solved by the Smart Assistant, which stopped working on some devices.
