Iphone 13 pro max white screen after IOS 18.1.1
My screen has been flickering for the past three days. Now, it just flickers a bit when I'm using my phone and then it turns to a whole white screen till I lock my phone and wait a bit and then reuse it. It randomly does this but it's getting worse. I didn't drop it or have anything happen to it. This only started happening after upgrading to the IOS 18.1.1. PS: I did restart it multiple times but it didn't help. Any advice?
iPhone 13 Pro Max, iOS 18
