So these things are trash! They keep lifting off the edges about a month or so after a perfect install!!
I Have no joke purchased this 7 times!!!
Amazon luckily has sent me 4 of those free but the other 3 I had to pay for myself! I am doing nothing wrong. It is a simple mindless process in my opinion. Its the crappy glue that they are using that has to be the issue.
Does anyone know why this keeps lifting on the edges like this a 3+ weeks after install?!!!
My second install has done this after two weeks. The first install worked fine for 4 or 5 months since installation last year.
The lifting for me was actually on the Bixby button side of the phone, but in the same general location as the OP, but a bit longer, and it appeared out of nowhere. My case definitely doesn't apply pressure to the glass (it's a Ringke Slim).
However, I do have a bit of a theory as to the cause...
When I installed this Whitestone I allowed the LOCA to travel too far down the phone before releasing the glass. When the glue flowed, I actually ended up with a small area with a few bubbles showing, exactly where the OP had his problem. I managed to work the bubbles out, and I thought I had a good install.
I'm wondering whether the thickness of the glue in those edge areas about two thirds of the way up from the bottom of the phone is less than the other areas, and this is the cause of the lifting problem. As most of the glue was in the lower half of the phone when I dropped the glass onto it, rather than the glue spreading out evenly from the centre, I noticed that it spread out to the sides, then up the edges, meanwhile also spreading up and out - these two flows ended up meeting in the Bixby/Power button area, and on one side for me, actually met at the very edge, leaving an island of no glue by the button forming a bubble that I managed to work out.
If this pattern of flow also happened on the Bixby button side, but instead of a bubble it just left a very thin layer of glue, then it could explain why that area is susceptible to the lifting problem.
I know we shouldn't be having these sorts of problems, but there doesn't seem to be a better option for protecting the screen of the Note 8 with a full-adhesive screen protector.
