BoyThink TPU Textured Rubber Case
Another excellent case for the 2018 Galaxy J7 is the Boythink Textured Rubber case. It has a unique look, feel, and design, one that's similar to Samsung's Hyperknit case for the Galaxy S9.
The company is using a soft, lightweight, and flexible TPU material that's extremely durable. Then, they added a unique cutout design and textured "plaid" finish to the back of the case. This keeps it lightweight, prevents accidental drops from a slippery phone, and will absorb impacts from drops and damage. This is a nice little case for the Galaxy J7 that comes in 7 different colors.
This one comes with a built-in screen protector if you're interested.
