Best ultra thin cases for Galaxy S9 and S9 Plus: Slim and minimal does it, right?

The Samsung Galaxy S9 and S9+ are two beautiful devices that are still one of the best looking and best performing Android smartphones. Much like any other flagship smartphones, the Galaxy S9 and S9+ are fairly sleek and slim.

However, when we choose to slap on a case, the case completely ruins the slim feel of the device which totally takes away the point of purchasing this beautiful glass sandwich designed smartphone.

Fortunately, this does not mean you have to sacrifice protection by choosing not to rock a case, instead, we’ve scoured the internet to find the absolute best slim cases for the Galaxy S9 and S9+.

These ultra-thin cases offer a good amount of protection against the scratches and all while not adding any bulk to the device. A fair warning here though: Of course, you can’t rely on these cases to absorb the damages caused by heavy falls.


Given below are the best Galaxy S9 and S9+ cases that are very thin.
