I'll tell you my story. I bought an iPhone 15 Pro 256GB in Black. It arrives home, beautiful, but it had two problems: some darker spots on the casing, on the volume buttons, and a big speck of dust inside the ultra-wide lens. I decided to return it since the dust speck was clearly visible when I took backlit photos. I went to get another iPhone with the same specifications and managed to pay about 90 euros less thanks to a deal. I get home, open it, and it's perfect... but there's a microscopic chip on the back glass, about one millimeter in size, near the titanium edge, relatively hard to see. I decide to keep it because returning it would force me to buy another one and pay more, and in the end, the flaw isn't that noticeable. However, I'm disappointed with Apple's quality control. It wasn't like this before; the last iPhone I had was an iPhone 5S, which I loved, perfect in every way.
