Apple is still dealing with the iPhone X responsiveness issues when exposed to cold temperatures, but it may have another problem on its hands. Apparently some iPhone X units are developing an issue with a green line going vertically across the display. All the affected units were reportedly working fine when taken out of the box, but after some time the line pictured below appears.
By the looks of it the issue is either caused by an issue with the display controller or by the ribbon cable connecting the screen, but it’s hard to specify without having seen a defective device in person.
Apple is yet to comment on the matter, but users who have experienced the issue on their phones say that they got their phones replaced under warranty. So if your iPhone X happens to develop such an issue – take it straight to the company’s local office to get your replacement.
Given that the issue takes some time to develop, it’s hard to estimate how wide-spread it is. Apple choose a really unique screen for the iPhone X, not to mention that it’s the first time they went with OLED on a phone, so at least some issues were to be expected. Hopefully it doesn’t end up inconveniencing too many users.
