I've been checking into the protectors.. Zerolemon have a newer 2 layer kind of protector called the Zeroshock. It looks great but the youtube reviews of it say that the inbuilt screen protector sucks, fingerprints stick to it and it messes with the proximity sensor. http://www.amazon.com/ZeroLemon-Shockproof-Compatible-International-S4-R-Black/dp/B00DZU0SPO
I'm wondering if I could somehow replace it with this tempered glass protector you've just mentioned.
