I had a not so good fit with the ESR on mine on Friday, and saw the same thing on the top edge. I tried two of the three pack on my phone with not good results. I then ordered the Spigen GlasTR EZ fit.
While waiting for it to arrive, I tried the third ESR protector on my wife’s phone that we set up today and that came out perfectly.
I got the Spigen a little while ago and installed on my phone and so far looks good. I did have to use the tool, as per above to smooth out the edges, and it looks good.
I wonder if there are some slight differences in the tolerances of the protecters onto the frame which is resulting in the issues?
