Protection Tips from Gorilla Gearheads
Despite the 0.38mm profile, the Galaxy S24 Ultra slim case provides genuine MIL-STD-810G protection when the phone lands on its corners or edges. Always keep the case on rather than removing it for presentations, as the risk of drops increases when handling the phone without protection.
Remove the case monthly and use a soft dry cloth to clean the interior channel where the S24 Ultra's titanium frame sits. Microscopic debris accumulating in this channel can scratch the titanium finish over time if left unaddressed. Never use abrasive cleaners on the HALS exterior coating.
When inserting the S Pen while the slim case is installed, apply the same natural motion you would without a case. The slot cutout is precision-aligned to allow natural stylus movement. Forcing the stylus at an angle can chip the case cutout edge over extended use.
Keep the Galaxy S24 Ultra slim case away from prolonged contact with sharp keys in pockets. While the HALS coating resists yellowing, the polycarbonate surface can develop fine scratches from key contact. A dedicated pocket or pouch slot in your bag eliminates this risk entirely.
What Is in the Box and How to Install
The Gorilla Cases Galaxy S24 Ultra slim case ships with the case itself, a microfiber polishing cloth, and an installation instruction card. Installation requires no tools. Power off the S24 Ultra and remove any previous case before beginning.
Align the case with the USB-C port at the bottom, then press the bottom edge of the phone into the case's lower channel. Gently press each corner in sequence until all four corners click into their retention positions. Confirm the S Pen slot cutout aligns precisely with the stylus port before using the phone. Test all buttons through the case to confirm tactile response is satisfactory.
