Common Galaxy S23 Ultra issues we check at inspection

  • Screen burn-in on Dynamic AMOLED 2X display. Ghost images from status bar icons, navigation gestures, or keyboard impressions visible on the OLED panel after extended use. Common on high-brightness, always-on displays.
  • Battery degradation below 80% health. The 5000mAh battery showing significantly reduced maximum capacity after 1-2 years of heavy use, leading to shorter battery life.
  • Scratches and micro-scratches on Gorilla Glass Victus 2. The glass front and back, while durable, are prone to fine scratches from everyday pocket carry and use, especially on the camera lenses.
  • S Pen functionality issues. The integrated S Pen may have connectivity problems, pressure sensitivity issues, or be physically damaged/missing.
  • Camera lens scratches or internal dust. Scratches on the exterior camera lenses or dust ingress affecting image quality. The multiple lenses increase the chance of damage.
  • USB-C port damage or debris. Wear and tear on the USB-C port leading to charging issues, slow data transfer, or complete failure to connect. Lint and debris are common.
