The Samsung Galaxy Note 9 is one of the top Android phones available, and it's definitely worth protecting with a case that looks good and adds minimal bulk. But not all cases are made equal, and sifting through the many options can be tricky.
The Caseology Symmetry line of cases is slim with very little added bulk for a great level of drop protection. These cases feature a clear back and a plastic bumper around the edges that protects from drops and gives the phone a nice grip. The bumpers also protect the corners, but leave the area around the S Pen open for access and use.
This folio style case is another good option for the Galaxy Note 9. It offers a spot for a few cards, cash and an ID, but also folds back into a stand to prop up your phone. It even has a magnetic clasp to keep the cover shut. The case is also available in a number of different colors.
The Catalyst Impact Protection Case is a slimmer option that still provides serious protection for the Galaxy Note 9. It has some cool carbon fiber and brushed metal details on the back, and it doesn't cover up the S Pen hole. It's grippy, too, although it does pick up fingerprints easily.
