The phone is a big seller for Samsung so there are a ton of people out there with them. People are more willing to voice their opinion when they have, or someone they know has, a bad experience. I've had mine since launch. No screen protector and I've kept it in a slim case or no case. No problems so far. Not even scratches. I bought the Samsung Protection Plus for peace of mind. Not because of this specific phone but just because it's something I've done with all of my phone's. New flagship smartphones are expensive as heck so a little insurance can save you in the end.
Anyways, I view this as being similar to the whole 'bend gate' thing with the iPhone 6 plus. I had one on one of my lines from launch until a week ago and had it on me every day, never had it bend. It was sat on a few times, on accident of course, and kept in a tighter front pocket at times that put a decent amount of pressure on it when sitting but it never bent. Not even a little bit and I'm 365 pounds so when I accidently sat on it a few times it surely should have taken the shape of my butt according to a bunch of people lol. I think a lot of it with the cracking screens could be luck of the draw but it's a small amount of people it seems to be happening to, and the majority it has happened to seem to have dropped their phone which is a gamble with any phone. Even with my iPhone 6 plus I dropped it several times in the thin leather Apple case on concrete/asphalt and was lucky enough to pick it up and have it still be in one piece yet my brother dropped his in a much thicker more protective case from a few feet and cracked his screen.
I can tell you that so far I am really enjoying the Note 7. More so than my GS7E and iPhone 6 plus. I haven't scratched or broken it yet and don't plan to but crap happens. I got the insurance for when that crap happens. If nothing else I will file a claim in 2 years so I can pass down or sell a refurbished/new one that will have a new battery and be good to go for a few more years.
Almost forgot. My Note 7 fell off my gun safe. Close to a 6 foot fall with a thinner case on to laminate flooring and came out unscathed. It landed on the corner then bounced and landed face down. I had a flash of reading horror stories thinking it for sure would be cracked. Picked it up and looked it over. Not a scratch.
