Apple has just released iOS 11.1.2, which, as promised, fixes an issue where screens on iPhone X devices could become unresponsive in cold weather.
Users had reported issues with missing touch event detection on the iPhone X when it was carried outside in temperatures of around 50 degrees Fahrenheit or lower. Typically, this would mean selectively missed touch input, so that typing was either difficult or impossible, or attempt to open apps or tap on other interface elements appears to just not work.
This update is specifically designed to address a bug where the iPhone X could become temporarily unresponsive to touch input when moving from warm weather to dramatically colder temperatures – like venturing outside in winter in Canada, for instance.
The update is also said to address an issue where Live Photos and videos captured on the iPhone X might show some visual distortion. It’s available now, and should show up if you go to the update section of your phone’s Settings app.
