I just installed my tempered glass screen protector that came with my Zizo Bolt (S7 Edge) & am having this issue.
I Google it &, a'course, you guys came up.
=)
In the corners & a little on the edges, it crackles like the plasticky glass is trying to stick, but pops right back up again.
I am a klutz, so I'm overprotective of my phone.
I wish there was a Lifeproof for this model! My S5 was Lifeproofified & had a crazy experience of being buried in rubble, broken glass, hunks of cement, it had rained a couple of days, et cetera.
I found it five days later & my phone was in perfect shape, as was the case! Just needed a wee scrub.
With this phone, the Otterbox Symmetry was all Telus had at the time & it didn't feel secure at all.
Then, I got a Ghostek, which is now falling apart. =(
Now, I've got this Zizo Bolt & I hope it & this disconcerting tempered glass work harmoniously.
If not, so many tears.
