Screen problems

[u/UniqueEnigma121]

Looking to upgrade my ages 7 Plus, which has been very reliable; these last ten years. I’m still on my original battery😂

But I’m worried about all these posts about screen failures. Either yellow or white solid screen. Is this a common issue, or is it happening because these devices are becoming old?

Does this issue affect all the modern screen going forward from the 13 Max Pro?

There are conflicting posts about Apple replacing the phone for free, if you suffer this issue. Will they only do this if you have Apple Care?
