Maintenance

Proper care will help maintain the appearance and functionality of your Frame Case.

  • Cleaning: Use a soft, slightly damp cloth to wipe the case. Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the plastic material.
  • Environmental considerations: The side key of the Galaxy S23 Ultra Frame Case contains a minimum of 34% UL-certified bio-based content (UL ECVP 9798).

Troubleshooting

  • Difficulty removing the case: The case is designed for a secure fit. To remove it, start by gently prying one of the bottom corners away from the phone, then carefully work your way around the edges until the phone can be lifted out. Avoid excessive force.
  • Case appears scratched: Minor surface scratches may occur with regular use on plastic materials. This is normal wear and tear and does not compromise the protective function of the case.
