Black edge around screen

I received a iPhone 13 Max this week. Very nice upgrade to a 7 Plus. Today my Speck screen arrived, I squeezed the phone in, and suddenly I have a black frame around my entire screen and a large black rectangle at the top of the screen. I searched and all solutions suggest turning off everything in accessibility, i.e. speech, zoom, voice over, etc. Did all of that, still have this ugly frame and black box around what was before a beautiful large to the edge screen. How do I correct this?

You could start by checking whether Settings/Display and Brightness/View is set to Standard, instead of your presumably previous setting of “Zoomed”.

If that doesn’t do the trick, Settings/Accessibility has an option or two which might be the culprit.

Luck with it.

I meant to say Speck case. Once I put it in the case, my screen appearnace changed.
