Help!!

I would like some information, I would like to know the diagonal dimensions of the rear glass panel where the cameras for the iPhone 15 Pro Max are placed Please

All dimensions of iPhones here : https://www.ios-resolution.com

Ans detailed spec of 15 Pro max: https://www.gsmarena.com/apple_iphone_15_pro_max-12548.php

But you want the dimension of a rear glass. It seems to be the same as the front glass. If you look for dimensions of the cameras bump, you could evaluate it using the image below and knowing the overall dimension.

But the safest may be to go in a shop and measure it.

the one where I marked with the red stripe
