The iPhone 8 looks almost similar to its predecessor, iPhone 7 except for the back glass panel that provides additional weight to the device making the device feel very comfortable while holding in the palm of the hand. The device provides a premium design to the phone, though, but also decreases the durability of the device. The company claims to have used Saffire glass in the device which starts taking scratches at the level 6. The side metal panel leaves colour when scratched. And for those who do not know, the back glass panel of the iPhone 8 is more expensive than display.
