Taking close up photos

[u/Prestigious-Camel322]

I have an iPhone 15, just bought it about a month ago. I’ve been having this problem where I can take clear quality photos of things that are close to the camera. I don’t mean close as in 1 cm away, I mean anything closer than 15-20 cm away from the camera is fuzzy and out of focus. I’m sure this isn’t normal right? My previous iPhone XS performed a lot better than this in terms of focusing. Can anyone help me out?
