Sell my V40 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 V40 ThinQ issues we check at inspection

Screen burn-in on P-OLED display. Ghost images from status bar icons, navigation gestures, or persistent UI elements visible on the P-OLED panel due to its nature.
Battery degradation. The 3300mAh battery often shows significant wear after 2-3 years, leading to reduced screen-on time and frequent charging needs.
Cracked rear glass. The Gorilla Glass 5 back is prone to cracking from drops, especially if the phone is placed on hard surfaces.
Water damage indicators tripped. Despite IP68 rating, internal water damage indicators may have tripped due to submersion, leading to corrosion or component failure.
Camera module issues. Problems with autofocus, image stabilization, or specific lenses (wide, telephoto) can occur due to internal component wear or minor impacts.
USB-C port issues. The USB-C port can become loose, damaged, or clogged with debris, affecting charging and data transfer capabilities.
