Samsung Galaxy Fold uses the color scheme of "cosmic black", "space silver", "mars green" or astronomical blue. Adopting a unique folding design, the mobile phone screen has been expanded to 7.3 inches, the inner screen is folded in half, and the back also has a 4.7-inch screen.   Considering that some users may turn the screen repeatedly to reduce the pressure of work and life, Samsung has added a variety of colors to the back and hinges to help users reduce pressure while indirectly showing the owner’s taste preferences. .
