I have ghost armor which covers the entire phone but the sides and I got the matte backing flim and I really like it. I got it after my first S6 developed a big scratch on the back out of no where.
It seems the tempered glass screen protectors are taking a bit longer than planned, the adhesive is still an issue. Amzer was supposed to have theirs out by May 1st and still nothing.
Well, I DID return my S6 Edge today, simply because of the lack of a tempered glass screen protector being available. I am using the S6 with a perfectly installed ZAGG tempered glass! I really doubt that a good one will ever be released for the Edge...
I think a company called oxil has a tempered glass protector for the s6 edge but its €50 here in rip off Ireland so i have decided to go without! I have never broke the screen in any of my phones anyway so touch wood i never do
