What is the thinnest glass available for the front and back of the s8? I was considering just using those instead of a case. Also, have tempered glass protectors fixed the 2.5d issues? Last time I bought one a few years ago, they weren't great
I have used the Gpel on my S7 Edge and been very happy with it. They have the S8 and S8+ versions on Amazon at half the price they are on their website.
I had a screen protector for the S7 with a black border. You just have to be careful with applying them to make sure they're centered, or else there will be sensitivity issues. Otherwise, great protectors.
