Sell my G8 ThinQ

Condition guide

How we grade every device that comes in, in plain English.

Condition	What it means
Flawless	No scratches or scuffs anywhere. Screen and body look like new. Fully working, no cracks.
Good	Light, minor scratches or scuffs from normal use, none deep. No cracks or dents. Fully working.
Fair	Heavier scratches, scuffs, or a small dent, but no cracks in the glass or screen. Fully working.
Cracked screen	Cracked or chipped screen or back glass, but it still powers on and the touchscreen works.
Broken	Powers on but has a fault, a bad display, or a part not working (camera, buttons, Face ID).
Won't power on	Won't turn on or hold a charge. We still buy it for parts.

At inspection

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.

Almost always. Carriers pay "up to" headline amounts as bill credits spread over 24 to 36 months, and only if you buy a new phone and stay on their plan. BuyBackBear pays cash after inspection, no strings.

Back up, remove your Google and manufacturer accounts (to clear the factory-reset lock), remove your SIM/SD card, then factory reset. We wipe it again to NIST 800-88 standards and email you a Certificate of Data Erasure.
