These cases don't bulk up your S23 Ultra
There is absolutely no shortage of incredible S23 Ultra cases out there, but some of them can be a bit too thick for everyday use. While these thick materials offer extra drop protection and provide a reassuring heft, they don't fit well into a pocket and can make the phone harder to hold if you don't have large hands. Case designers know this and have created a number of cases that are both thin and protective for the Galaxy S23 Ultra.
The Incipio Duo looks fabulous on the Samsung Galaxy S23 Ultra. This stylish slim case has a wonderfully grippy texture all around. You can easily use all the wireless charging features of your phone since the case is so compact. The antimicrobial layer on top kills germs and the raised bezels add 12-foot drop protection.
Need something unique? The Spigen Cryo Armor looks very different from the slew of sleek covers out there. Its hexagonal pattern keeps the Samsung Galaxy S23 Ultra cool as it allows better airflow. The insides are designed cleverly with air gaps for better impact absorption and the case meets the military standard of drop protection.
Once you're done picking a nice case, grab a screen protector for your S23 Ultra if you don't have one already. Not even the most heavy-duty covers can protect your screen from cracking sometimes.
