Apple admits 'coldgate' bug with iPhone X screens, sudden temperature drop cited

Just a week after the iPhone X officially hit the shelves, customers have begun reporting problems with the $999 device's responsiveness in cold temperatures.

On Reddit, several iPhone X owners complained the handset's screen does not work upon stepping outside into a wintry chill.

While Apple recommends using its devices in temperatures above the freezing point, the issue so far appears to be occurring within the described range, causing problems with swiping and even FaceID, the Daily Mail reports.

Reddit user darus214 revealed the issue in a thread this week, "I've noticed that my iPhone X screen becomes very unresponsive as soon as I step outside.

"It literally takes 2 seconds from going inside to the cold outdoors and my screen stops being very responsive. I try swiping on websites and it doesn't register my finger. It's very noticeable. Is anyone else having this problem?"

A slew of other iPhone X owners joined the conversation to add that they, too, had been having similar troubles.

Some said the phone was failing to recognise their touch, while others said FaceID did not recognise them.

On Apple's support site, the firm recommends using iOS devices in environments where "the ambient temperature is between 0º and 35º C (32º to 95º F)."

Outside of this range, the device could act up in a number of ways.

"Using an iOS device in very cold conditions outside of its operating range might temporarily shorten battery life and could cause the device to turn off.

"Battery life will return to normal when you bring the device back to higher ambient temperatures."

But, in many cases, it appears the issue is occurring even when users are within the right temperature range.

One user noted that it was about 45 degrees F (7C) when they experienced the problem.

The issue occurs when the temperature drops suddenly, and Apple is already working on a fix, set to come in a software update, according to 9to5mac.

For now, the phone should return to normal within seconds.

Dailymail.com has contacted Apple for comment on the issue.

Just yesterday, the firm rolled out another update for iOS 11, following complaints of a bizarre autocorrect issue that change the letter 'i' to an A with a [?] symbol.
