I have an iPhone 15 Pro Max 256GB purchased in Singapore.
A few days after updating my iPhone to the latest iOS version, I noticed a green vertical line appearing on the display during normal use.
There is no accidental damage, liquid damage, or physical damage to the phone.
I already visited an Apple Authorized Service Provider, and the device was inspected. The issue remained even after the software was reinstalled.
I have also contacted Apple Support and have an ongoing support case regarding this display issue.
Recently, while using the phone normally, I noticed a second green vertical line appearing very close to the first one.
