Apple changed what lens is used for macro photos. It used to use the 24mm 1X lens and now it uses the 13mm .5X for macro photos. It requires learning how the new macro works and how you have to adjust settings to optimize your experience. Please review the App support article i linked to below.
Take macro photos and videos with your iPhone camera - Apple Support
In the camera industry camera manufactures, some models are refreshed every year to 18 month, depending on the cost. No one wants their $5000+ camera updated every 12 months. But less expensive models are updated as stated above. If you’re upgrading from a previous model, there is always a learning curve while you adjust to changes in hardware and software.
It seems that smart phone users demand improvements, but don’t want to apply themselves to learn new hardware and software and learn to take advantage of the improvements they demanded.
Learn your equipment via various means such as asking questions here and in more specialized communities on the internet. Larger metropolitan areas offer adult education classes and you can often times hire private tutors for a low rate. If you’re looking for free opportunities, Apple Retail Stores offer free classes and many websites offer free tutorials in the hopes of selling you a membership.
iPhones are evolving and becoming more serious photographic tools. In recent years, with every new model release, you see YouTube videos from dozens, maybe even hundreds, comparing iPhones to cameras costing $100’s and even $1,000’s more than an entire iPhone.
Apple uses computational photography, which is just a name for AI, to make the kinds of images you express a desire for. “We want point and shoot photography where we don't see parts of the image, or peoples faces, blurred.” In order to produce those kinds of images you have to learn how to use the tools that deliver those results. If you want better results, you have to learn to use the options and settings Apple provides.
How much time to you spend learning your new camera? It’s a fair question if you expect to continually get results that meet your expectations. You basically have two choices. Learn your iPhone or learn a separate camera that better meets your expectations. But believe me, I’ve used them all, Pixels, Samsungs and the myriad Chinese offerings. I could purchase any smart I like, but year after year I chose iPhone. In my personal experience, it’s the best smart phone camera available.
