CALIFORNIA:- Apple has addressed a glitch that caused some iPhones to unexpectedly start auto-correcting the letter “i” to a capital “A” and a question mark. The issue emerged when people updated their phones to version 11.1 of the iOS operating system. In a tweet, Apple said people could “fix it by installing the latest software update”. The update also addresses an issue with Siri. The company has not explained what caused the problem. The problem was highlighted last week when people trying to tweet messages such as “I got a new iPhone” found their posts were appearing as “A[?] got a new iPhone”.
