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 A21s issues we check at inspection

Screen damage (cracks, deep scratches). The PLS TFT display is prone to cracking or deep scratching from drops or impacts, especially given the plastic frame.
Battery health significantly degraded. The large 5000mAh battery, while good initially, often shows significant wear after 2-3 years, leading to poor battery life.
Charging port issues. The USB-C port can become loose, dirty, or damaged, leading to intermittent or no charging.
Software glitches or performance issues. Older devices may experience lag, app crashes, or failure to update due to aging hardware and software.
Cosmetic wear on plastic back and frame. The plastic build is susceptible to scuffs, scratches, and discoloration from regular use and handling.
Camera module issues. Dust ingress into the camera lens or internal hardware faults can affect photo quality.

Do I get more selling my Galaxy A21s here than trading it in with my carrier?

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 A21s 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 A21s back free, we never silently accept a lower offer for you.

Yes, when the buyer does what we do: a NIST 800-88 certified data wipe with an emailed certificate, photo evidence for any re-grade, and free return shipping if you decline. You're never locked in.
