First highlighted by the Financial Times, a new iPhone X issue is affecting users who try to answer incoming phone calls.
The issue strikes when receiving a phone call. Users will apparently hear their ringtone, but the iPhone X display doesn’t wake up. So users can’t select whether to accept or decline the call.
A delay can apparently ask for 10 seconds or more in some situations.
You can read more about the issue in an Apple Support site thread.
For its part, Apple has confirmed that it is looking into the issue.
