Common Galaxy S21 Ultra issues we check at inspection
- Screen burn-in on Dynamic AMOLED 2X display. Ghost images from status bar, navigation buttons, or keyboard visible on OLED panels after extended use, especially noticeable on the S21 Ultra's large, high-refresh-rate display.
- Battery degradation below 80% health. The 5000mAh battery, while large, shows significant degradation after 2-3 years of heavy use, common for devices with high refresh rate displays and 5G connectivity.
- Camera lens micro-scratches. The individual camera lenses on the rear array are prone to micro-scratches from everyday use, potentially affecting photo quality.
- Cracked screen or glass back. The Gorilla Glass Victus is durable but not invincible; drops can lead to cracked screens or the glass back, a frequent reason for AS-IS listings.
- S Pen functionality issues (if applicable). While the S21 Ultra has S Pen support, some units may have issues with S Pen detection, responsiveness, or Bluetooth connectivity.
- Charging port issues. Dust accumulation or wear on the USB-C port can lead to intermittent charging or data transfer problems.
