OnePlus India — Green line on screen after Android 12 update.

Right after I updated my phone to Android 12, green lines have started appearing on the screen. After doing some research, I found out the company has not mentioned anywhere on the update that there are voltage changes that will cause damage to your screen, specifically OnePlus 8 and 8 pro. I'm extremely disappointed by this as I have to search answer from other users who have conducted the research that OnePlus should have before releasing the update. I have called and emailed then many times just to get told to visit the showroom or no response from the mails respectively.
