White screen issue in iPhone 13 Pro Max

This is a user to user forum, no one here can see the diagnostic test on your phone.

If Apple doesn't want to repair it, there isn't anything that anyone in here can do.

You can either pay for the cost of repair or purchase a new phone as recommended.

What does that mean? If your screen is damaged, regardless of your opinion of their feedback, they will need to fix it.

were you able to fix your phone? I have same issue.

I had to reboot my phone for it to work. Hope it helps.

Thanks
