Common G8 ThinQ issues we check at inspection

  • Screen burn-in on OLED display. Ghost images from status bar, navigation buttons, or keyboard visible on OLED panels after extended use. The G8 ThinQ's P-OLED display is susceptible to this.
  • Battery degradation below 80% health. The 3500mAh battery showing <80% maximum capacity after 2+ years of use is typical for this model.
  • Cracked screen or glass back. The Gorilla Glass 5 front and back, while durable, can still crack from drops. Sellers often list these with 'cracked screen' or 'broken back'.
  • Water damage indicators tripped. Despite the IP68 rating, water damage can occur, and internal indicators may be tripped, leading to unpredictable issues. Sellers might not always disclose this.
  • Faulty charging port. The USB-C port can become loose or fail to charge reliably due to wear and tear or debris.
  • Camera module issues. Problems with autofocus, image stabilization, or specific lenses (wide-angle, telephoto) can arise.
