Apple has acknowledged the issue and says it surfaces when the iPhone X faces a rapid change in temperature. At this point, the screen does not work reliably in terms of registering touch-based inputs.
The problem is not common, and only a few users have reported the issue. Luckily, there seems to be a workaround, where locking and immediately unlocking the handset seems to restore functionality of the screen.
A fix was said to be just around the corner, and sure enough: Apple has just sent out a patch that fixes that rando-replacement once and for all. iOS 11.1.1 is now available, with this fix marked as the flagship feature. "It's very noticeable. Is anyone else having this problem?", Reddit user darus214 wrote. Apple recommends operating its iOS devices in temperatures 32 degrees and 95 degrees Fahrenheit. Apple notes that "Low or high-temperature conditions might cause the device to change its behavior to regulate its temperature". First is the autocorrect bug that's causing some devices to replace "i" with "A [?]", and second is a bug that makes the "Hey Siri" hotword stop working. But some Reddit users said they experienced an unresponsive screen well into that range.
'I try swiping on websites and it doesn't register my finger. "After several seconds the screen will become fully responsive again", Apple said in a statement.
To install the new update, open your iPhone or iPad's settings menu, tap General, and choose "Software Update".
Just yesterday, the firm rolled out another update for iOS 11, following complaints of a freaky autocorrect issue that change the letter "i" to an A with a [?] symbol.
