The S5 has a plastic build and offers a texture of little dimples on the back to give it a bit of extra grip. Samsung calls it "modern and refreshing", and it comes in four shades – blue, gold, white and black.
The S5 has a similar shape and weight as of the S4, but the latest version is just a little thicker at 8.1mm thick. It is a bit longer too, which is likely down to all the extra tech Samsung has crammed in. The Samsung Galaxy S5 is certified to the IP67 standard, meaning it can be submerged in water and is completely dust-proof.
