The iPhone 8's glass back is surprisingly tough, but it's still worth getting a case

The glass backs on Apple's new iPhone 8 and iPhone 8 Plus remind me of my iPhone 4 that I bought in 2010.

For the record, my iPhone 4's glass back cracked, despite the fact that it was in a case pretty much the entire time I owned it. 

Naturally, I was curious to see how well the iPhone 8 and iPhone 8 Plus' glass backs would handle drops. After all, Apple claims the glass on both the front and backs of the new iPhone 8 phones are the "most durable ever." Indeed, I certainly hope they're stronger than the glass on my iPhone 4.
