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 Galaxy S21+ 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 prolonged use. The S21 series, while improved, is still susceptible.
Battery degradation below 80% health. The 4800mAh battery, after 2-3 years of typical use, often shows significant capacity loss, leading to shorter battery life.
Cracked or damaged screen glass. The Gorilla Glass Victus front, while durable, can still crack from drops. Listings often mention spiderweb cracks or chips.
Cosmetic damage to Glasstic back. The 'Glasstic' (plastic) back is prone to scratches, scuffs, and micro-cracks, especially around the edges and camera housing.
Faulty charging port or USB-C issues. The USB-C port can become loose, damaged, or clogged with debris, leading to intermittent or failed charging.
Camera module issues. Focus problems, lens smudges, or internal damage to the camera sensors can occur, especially after drops.

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.

How do I wipe my Galaxy S21+ before selling it?

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.

If our inspection changes your quote, we send photo evidence and give you 14 days to accept or decline. Decline and we ship your Galaxy S21+ back free, we never silently accept a lower offer for you.

From $5 (won't power on) to $67 (flawless, unlocked). No listing fees, no shipping costs and no haggling, the quote you lock is the cash we pay if the device matches your description.

Where can I sell my Samsung Galaxy S21+ near me?

Anywhere in the US, no store visit needed. We email a free prepaid label, you drop the box at any carrier location, and payment goes out after inspection. Mail-in buyback beats kiosk and store walk-in offers almost every time.

Can I sell a broken Galaxy S21+?

Yes. Cracked glass, bad battery, even a Galaxy S21+ that won't turn on, we buy them all. Broken units start around $5, just pick the matching condition above for your exact offer.

Is a used Galaxy S21+ still worth anything in 2026?
