Before I received my Note 7, I had in-hand the following:
* Sparin tempered glass cover
* Skinomi plastic (wet-apply) front and back protection covers
* Ringke air case
I was prepared - or so I thought. The Sparin worked for a few hours, and even worked with the Ringke case, but after a few hours, the glass started to move, and the case started to push it away from the phone. The adhesive on the tempered-glass cases are only at the top and bottom - not enough to hold them in place. Eventually the glass cracked when I tried to reposition it. From what I can see, all the full-coverage tempered glass covers have the same adhesive in the same place.
So, to plan B. I applied the Skinomi on the front glass. It appeared to install properly, even on the edges. I waited a couple of hours for it to dry and put the Ringke case on. The Skinomi immediately crimped at the corners. It was quickly obvious, that NO cover - glass or plastic - would work with a case, even a minimal case like the Ringke Air. Amazon reviews confirmed this.
At this point, after reading a LOT of Amazon reviews, I realize the following:
1) You can have a case, but no front glass protection (not plastic or tempered-glass); or
2) You can have front-glass protection and a rear protector with PLASTIC (no tempered-glass) and no case.
Both of these leave you half-naked, plus, I don't like the plastic front-protectors.
I hate the thought of not having front-glass protection (especially after seeing the youtube videos) and, although I don't drop my phone a lot, it does happen. So, the decision comes down to: Which is the least of the evils?
At best, I'll be half-naked and afraid.
