Apple on Thursday released an iOS update to address complaints that the iPhone X's screen becomes unresponsive in cold weather.

Apple recommends operating its iOS devices in temperatures between 32 degrees and 95 degrees Fahrenheit (or 0 degrees and 35 degrees Celsius). But some Reddit users said they experienced an unresponsive screen within that range.
