iPhone 15 Pro Sharp edge between glass and titanium frame

[Grobaouche]

I just received my 16 Pro, coming from a 15 Pro that was quite sharp in the edges.

It is far better on my 16, unnoticeable to be honest, but I cannot say if it is by luck or industrial process improvements for all the 16s

I assume the fact that the back glass can now be swapped independently hurt the precision of fitting the glass in the frame.

I think your assumption is 100% on target.

My 15PM back glass last year was noticeably uneven and inconsistent around the frame. After the back shattered from falling out of my pocket, I had Apple repair the back-only for the first time ever. The phone actually felt nicer to hold, and the titanium rails would no longer catch on my skin slightly.
