Invest in a Durable Case

Despite its premium glass and aluminum construction, the Galaxy S8 Plus is susceptible to damage from drops and impacts. A protective case acts as the first line of defense.

• Choose from slim cases for everyday protection, rugged cases with shock-absorbing bumpers for active lifestyles, or waterproof cases for outdoor adventures
• Ensure the case provides raised edges around the camera and screen to prevent direct contact when placed face-down
• Select cases that maintain access to all ports, buttons, and the fingerprint sensor without interference
• For the Coral Blue variant, consider transparent cases to showcase the unique color or colored cases that complement its aesthetic

Smart Choice: Rugged cases with military-grade drop protection (MIL-STD-810G) are ideal for users in high-risk environments.

Regular Cleaning

Regular maintenance keeps your Galaxy S8 Plus looking new and functioning optimally. The Coral Blue finish, in particular, can show fingerprints and smudges more visibly.

• Clean the device weekly using a soft, lint-free microfiber cloth slightly dampened with water
• For stubborn grime, use a small amount of screen-safe cleaning solution (50/50 water and isopropyl alcohol under 50%) applied to the cloth—not directly on the phone
• Gently clean the charging port, speaker grilles, and headphone jack with a dry, soft brush or compressed air
• Avoid cleaners containing alcohol, ammonia, or abrasive chemicals that can damage the oleophobic coating and discolor the Coral Blue finish
