I’m coming from an 11 Pro. I’m disappointed in the camera. Many photos contain blurry spots around the center. And there’s something weird with taking photos at close range. I notice when I scan QR codes they often appear blurry on screen. And sometimes when I photograph a room, the macro mode will kick in.

A universal back gesture doesn’t make any sense. Windows Phone had a dedicated back button. Which was a mistake. There are many situations where there isn’t a logical “back”. It should only be available when it makes sense.

I went from an 11 Pro to a 15 Pro and I share your feeling that it isn't that big of an upgrade. The photos, especially in low light, aren't that much better. In fact, I even think my 15 Pro camera has a blur problem. A lot of photos are blurry, less sharp than photos taken on my 11 Pro. There are others that report similar issues: https://www.reddit.com/r/iphone/comments/16z7fmb/brand_new_iphone_15_pro_blurry_camera/

Video does look better. But recording 30 fps portrait video still shows some stuttering some times.
