iPhone X, green band
Hello! I bought an iPhone x 256 mg a year ago, I used it regularly throughout this year. but today a green vertical band suddenly appears, which interferes and distracts.
iPhone X, iOS 13
Question marked as
Has the phone been dropped or any parts of the hardware been replaced recently, for example the display or battery?
In any case, you should get the phone checked by Apple or an Authorized Apple Service Provider next to your place.
