My friend got this iPhone X and it suddenly has a bright green line on the left side of the screen. Whole display getting bit greenish because of it. The warranty is also finished because it's more than a year and a half he bought it. It happened suddenly because he is assuring nothing happened like dropping it or any kind of water damage. He tried to reset it but the result is the same. Any ideas on how to fix this?
This issue usually comes together with issues with touch response for which there is a replacement program by Apple in which the display would be replaced free of charge outside of the regular warranty period. (https://support.apple.com/iphone-x-display-module-replacement-program)
Visit your local Apple Store or Service Provider and check to see if it can be fixed under this program.
