Can you check if the iPhone screen has been replaced or not thanks to iOS 15

The most significant of the features not mentioned is the ability to detect whether your iPhone has had a screen replacement or not.

Specifically, if the iPhone has a screen replacement, iOS will display a warning right below the Warranty package in Settings > General > About. This warning reads as follows: Important screen message. Can't verify that this iPhone has a genuine Apple display.

If you see this message, it means that the iPhone you are holding has a screen replacement that is not manufactured by Apple. In addition, it is also possible that it is a genuine Apple screen replacement, but the replacement process is performed by a third party and not by Apple or its authorized Apple partners.

If you don't see this message, it means that the iPhone screen has not been replaced or has been replaced, but it was done by Apple or an authorized partner.

This is a useful feature when you are looking to buy a used iPhone.

Other useful small features of iOS 15 include the ability to search even when powered off, the ability to group and summarize notifications, Focus modes.

Previously, on iOS 14, Apple also added another feature to help users easily detect whether the iPhone is an international version or a carrier lock. iOS 14 will also display a warning if your iPhone has had a camera replacement.
