iPhone X is affected by a new serious problem that seems to bring headaches, literally, to users who bought the new smartphone model launched by the Apple company last year. In the video clip below you have a demonstration of how the iPhone X screen "flickers" during a test done to demonstrate how Pulse Width Modulation technology is used, the one accused of generating the problems.
iPhone X uses PWM, like many other mobile phone models, for the OLED screen, it "pulses" at various frequencies, but these should not normally be visible to users. Unfortunately, it seems that some of them see and have a headache because of the way PWM technology is implemented, the test below is intended to show that Apple does not use it in a very great way in the phone .
iPhone X is causing real headaches for users
iPhone X is the first Apple phone model that uses PWM technology, but it seems that for some people it comes not only with headaches, but also with eye pain, or severe fatigue generated by its constant use. iPhone X customers who suffer from these problems are very few for now and complain on various forums, but the problem itself is not so big as to put Apple "on guard".
iPhone X was praised by experts as having the best screen ever implemented in a mobile phone, the American company taking care to offer the latest generation technologies at the price requested by him. Of course, it is impossible to do everything perfectly, so the iPhone X does not offer the perfect experience for everyone, and problems such as the PWM system are more related to the user and not to the technology itself.
