Luckily, Apple is already aware of the problem and is creating a fix which will be delivered through a software update.
We don't know what's causing the issue, but it's clear it isn't hardware-related - and that's good, because there's no telling how long it would take Apple to muster up replacement handsets.
Of course, you might think it entirely nuts that Apple needs to ship a full iOS update to update such a simple issue, particularly when it's only just started shipping an upgrade that restores a working "i" key when typing out a message.
Ever since iOS 11.1 came out a week ago, many iPhone users complained about the glitch that automatically replaced a lower case "i" with odd characters in their pithy texts and social media posts. Go into Settings General Software Update on your iPhone or iPad to begin the update process. "I try swiping on websites and it doesn't register my finger", wrote the original poster. Apple's own website says that iOS devices work best in temperatures above freezing, and using them in cold weather can "temporarily shorten battery life" or cause the device to suddenly shut off. Hopefully this iPhone X software update should help fix it for those users who need to use their phone in the cold.
"Battery life will return to normal when you bring the device back to higher ambient temperatures".
Others said they had been experiencing the same problem.
Apple previously provided users with a workaround to mitigate the issue.
Dailymail.com has contacted Apple for comment on the issue.
IOS 11.1.1 has just been released, and it comes with a small but important update - a fix for the odd autocorrect bug in iOS 11.1 that has been automatically changing the letter "I" to "A [?]" for some users.
