iPhone 12/13 mini logical resolution is incorrect about iosref HOT 3 CLOSED

Thank you for letting me know about this. I'm planning on making changes to the iPhone 12/13 mini resolution, but I'm still trying to understand how exactly the quirk for the mini devices manifests itself. As far as I can tell, the situation is similar to the iPhone Plus models, but not identical.

Specifically, if you check in a simulator, these are the scale and width values you get for iPhone 13 mini:

UIScreen.main.scale: 3.0
UIScreen.main.nativeScale: 2.88
UIScreen.main.bounds.width: 375.0
UIScreen.main.bounds.size.width: 375.0
UIScreen.main.nativeBounds.width: 1080.0
UIScreen.main.nativeBounds.size.width: 1080.0

But for iPhone 8 Plus, you get these values:

UIScreen.main.scale: 3.0
UIScreen.main.nativeScale: 3.0
UIScreen.main.bounds.width: 414.0
UIScreen.main.bounds.size.width: 414.0
UIScreen.main.nativeBounds.width: 1242.0
UIScreen.main.nativeBounds.size.width: 1242.0

So the nativeScale is 3 for plus models but 2.88 for mini models. I'm still trying to understand what this means exactly for the figures on the website.

@paulozoom Ok so I updated the iPhone 13 mini logical resolution to 375 × 812, updated the scale factor to @2.88–3x and added a footnote:

iPhone 13 mini and equivalently sized devices have a logical scale factor of 3x but a native scale factor of 2.88x. The logical resolution of 375 × 812 is multiplied by 2.88 to reach the actual resolution of 1080 × 2340.

But I'm not totally sure if this footnote describes the situation correctly. I'm open to suggested changes.

I wasn’t aware of this discrepancy on nativeScale, but I’m not a iOS developer. I do wonder if Display Zoom could be playing a role here? WDYT?
