After the iPhone X launch event there is a lot of discussion about its distinctive “notch” at the top of the screen, which is housing the cameras and sensors that enable Face ID.
Recently an online technical team exposured an iPhone X, which the Wifi and signal notch on the uppper right corner is actually turned black. Reportedly they can't fix the problem on iPhone X after restarting.
As the iPhone X with OLED screen, the screen shows sub-pixel independent lighting. It is possible to turn black on the upper corner. Is one of the new bugs on iPhoneX ? We are not sure, please follow 3uTools' update.
