This is unfortunately pretty common. If you shine a flashlight into the camera lenses more often than not you’ll probably find some dust underneath them. That one is more apparent though.
I have an iPhone 14 Pro. Mine has a few bits of dust underneath two lenses but it doesn’t effect my photos.
They swap it out with another one, chances are it might have it too. Maybe just not show quite as bad. They are mass produced devices, and dust is everywhere. It doesn’t matter if it’s super duper IP 6000 resistant, dust is all over and it WILL get in there eventually. Just look at the back of your camera modules and see how much dust they collect for example. There’s no way few specks aren’t making it in.
I stopped letting it bother me. If it starts affecting my photos then I’ll reach out to Apple.
I have a 14 Pro. I tried the 15 Pro and returned it. I fully realize the 14 pro is still top of the line, but regardless:
I just didn’t like the way the titanium felt. For some reason to be the stainless steel just feels more substantial and solid, and I normally like light weight things. I’m probably in the minority but I like the way the 14 pro felt better.
And yeah, the battery life didn’t seem great. Granted the 14 Pro’s isn’t exactly amazing either but it gets me through the day.
I’m going to wait for some refinements to the new titanium build. But honestly, once the standard series gets 120hz, I’ll probably stop buying Pros.
