In my experience no phone is perfect. It’s just that people aren’t so obsessed to catch everything. I try not to but I just have good eye. My 13P had a bit redddish on the left screen at night and a not great battery. Thankfully my 15PM seems mostly perfect. It has one little dot where the coating is missing and the metal is showing (mine is black). But it’s as small as a white spec of dust near the glass so I’ll be able to ignore it. Also cameras seemed fine today, but tonight against a different light I casually noticed a small dust particle under the main lens. But it’s in the outer part of the lens, where it won’t matter in any picture, so I’m able to ignore it too. Screen seems quite uniform too, even at night. I had worse. What would I risk with an exchange? A phone with a bigger scratch, a dust particle under THE MIDDLE of the lens (will still not be visibile, but is more annoying). Or even worse, an overheating phone, dead pixels, a not so sensitive touch screen, misaligned lens, defective speakers, wonky or bad clicking keys, bad assembly between chassis and back glass, a bad battery. I mean, there’s a lot that can go wrong with these phones and I can guarantee you, no phone is without at least one or more of these even if they cost 1500$. There are some things that I won’t stand ever (a dead pixel for example), but most of everything else I can accept. It bothers me, but the chance of getting a worse phone and starting a return chain is pretty high. Most people don’t notice many things so you can be under the impression that most phones are “perfect”. They are not
