Just applied playproof case and full edge tempered glass from rhinoshield.


Why I couldn't find this case on its official website?
You are ordering from here is it?
https://rhinoshield.ioP/S : Short review
I've been using spigen ultra hybrid since my note 4. And I am using Spigen Crystal Shell with my iphone 7 plus. I really am a fan of clear case and also a real fan of spigen product.
The same exact problem with that back plastic cover is, it tend to get slippery over times from greasy hand.
I am not sure this issue applied to any other brand that has clear back case but its happened to both of my phone.
Some YouTube reviewers said that this case wouldn't let any dust from getting inside the case but mine is otherwise.
The dust is there compiling at the cutout of the case such as at the camera cutout, speaker, silent switch, etc and some of them even reach at the center of the back case.
Plus it is a clear case, so the dust is visible enough to make me annoyed.
