TL;DR if its not to sharp, life/live (sorry for my amateur english?) with it and enjoy one of the best smartphones out there ;-)
I registered here because of the M1 flickering issue but saw this thread and have the same experience like others.
I got my 15 Pro and does not updated every year or two but waited 3 years after my 12 Pro. So I was a thrill of anticipation :-D
As I got the 15 Pro NT I was instantly disappointed. Is feels so cheap in regards to the 12 Pro. After inspecting I found that
- the Glass backside feels very different, cheap. If you brush your thumb against it is a different sound/its louder. On my 12 Pro and my business phone a 14 Pro this is not the case. I think it has do to with a new Glass material or that the glass is not glued together like before.
- the color (NT) was not as goldish like on Apples websites and in the hand ons. It has a noticeable yellow and gold tone in the media. But in real it is so dull and gray. Looks more like a stone surface than glass.
- and I feels the sharp edges on the back on first or seconds use. Top, bottom, left, right, everywhere on the back.
My summary is that the 12-13-14 Pro devices had a better haptic and build quality. But the 15 Pro is a huge improvement in every other aspect and now after some days finally I like it a lot
You have to see all the benefits and should not concentrate to much at the negatives. After reading this thread I feels it every time but after not reading this thread and used the 15P NT some days I forgot the sharpness.
I do not love the color but like it now. I used to the new glass feeling and the form is now ok for my hands.
I will not replace it and likes now my 15 Pro!
In the past there were similar issues with the most iPhones. The 4, 4S, 5, 5S and X, XS, 11 Pro had edges which you could feel on the display side. This is more annoying than on the back bc you feel it every time using the device.
I replaced a lot of iPhones in the past regarding this and other qualify flaws. So I said to me when the display is ok, the backside it not to much important for me.
And on the other hand, other brands has the same issue or are even more worse in the hand.
