Accidentally dropped my Edge

I f*cked up. I f*cked up real bad. I was in the bathroom and I decided to take my Edge's cover off cause I didn't want my phone to overheat while I was playing DS games to keep myself entertained as I waited for my cousin to bring me some rolls of toilet paper. As soon as she left, I gently put my Edge ON the cover itself.. I tried to pick the cover up for some reason and boom. It slid off and fell from ABOUT 50cms (It fell from the corner of my bath tub). It also made a 360° in the air and landed flat on the screen. Let's just say I needed some more toilet paper at that point. I picked it up and checked EVERY single nook and cranny and it doesn't seem to be damaged. Should I be looking at a particular spot ? Should I just send it to Samsung since I'm paranoid as f*ck ?

Now, this happened with my Nexus 4 as well. A caseless Nexus 4. Around 10-12 times. Landed on the back about half the time and after 2-3 years I still can't find a single crack on it. The Edge's glass is stronger than the Nexus 4's, right ?
