For people who can’t find any difference, I’ll explain. In the first image, at the top bar you only have the WiFi icon. On the image of iOS 27 beta 3 you can see that 5G has been added in the top bar besides WiFi :)
It’s ridiculous how slowly iOS adds features that Android has for years. Sure Android “steals” good features from iOS too, but at least they do so almost immediately after Apple launches them.
