You may be able to unlock the £999 iPhone X with your face, but this is not much good if it cannot take calls.
That is the latest grumble among Apple customers, thanks to a software glitch that is freezing the phone display.
Apple’s online support forum is flooded with complaints describing the frustration of hearing their phone ringing for “six to eight” seconds while staring at a blank screen, without the “slide to answer” function.
Apple is understood to be aware of the issue and customer assistants are advising customers restart their phones – although this is a temporary fix which only lasts for “15 more calls”, according to one customer.
“Sometimes the screen does not turn on and this problem can last for a few seconds or remains permanent until I do a forced reboot,” another wrote on the forum.
