I'm done with screen protectors for the S7 Edge. Pulling the last one off. I have a case with bumper which keep the screen from hitting the ground if the phone falls. I've got a little, drawstring jewelry bag to put the phone in when it's not in my back pocket against soft fabric. Either the protectors pop off, or they negatively affect screen sensitivity. Using a protect without a case makes no sense. Had the phone has a removable back, like the Galaxy S5, this wouldn't be a problem (since those cases attached to the back of the phone). Also, a good reason for a case? The phone is slippery. You really need a grip. If you love the color, get a cheap, clear one. I had one for my S5 and it worked really well.
