Using this smartphone case is super easy. Just slip your phone into the case, and it'll be well - protected. Since it doesn't have a camera hole, it's designed to fit a wide range of phones. When using it, make sure your phone fits snugly to avoid it falling out. For maintenance, you can wipe it clean with a soft, dry cloth. Don't use harsh chemicals as they might damage the case. Also, keep in mind that the images are of prototypes, so the actual product might have minor differences.
