Been using my S7 with Spigen Neo-Hybrid since March and not a single scratch, did purchase a Sikomi "liquid" screen protector but I've been hesitating to apply, seem a bit too complicated but I've been getting nervous after so many threads with S7E getting screens cracked out of nowhere.
Had my Z1 and Z3 both with high quality Nillkin screen protectors, you couldn't tell there was a screen protector at first glance but it was quite expensive and did protect the Z3 screen from a really high drop on a bunch of rocks (with Spigen crystal case with "air cushions") only the screen protector cracked, the phone was completely untouched, so yea, accidents do happen!
Here is what I'm doing right now, I turn off my S7E and leave it at home or in my car and take my Lumia 930 with me instead since everyone knows my two numbers, that's when I'm out for a walking, playing with the kids, the dog... and so on... The Lumia is sturdy as hell, doesn't even need a case, never got scratched. It's like a Nokia 3310.
