i reached out to phonerebel about the buttons and logo plate and like always got a quick reply. here’s what they said:
“Hey Darrin, the buttons have been extensively tumbled for deburring, and then go through a rigorous multi-step PVD coating process.
In our testing the PC sticker degrades the click of the button, and is not needed because of our new PVD coating process.
The rebel back logo is .5mm below phone back glass, it shouldn't make constant contact with glass.”
the buttons on the inside do feel really smooth. i really thought they had padding. i’ve gotta say, the gen 5 is my favorite case ever. looks great to me, has tremendous grip, easy swiping in all directions and seems very protective. i’ll be using it without worry.
edit: i just wanted to add that the material the case is made from feels so good. it’s different from other plastic cases i’ve had.
I received this same canned response. Wonder why they had protective backing on the Gen 4 buttons if they didn't need them?
