Questions and answers

Is there any real difference between these two?
No. Both are the Galaxy S21+ 5G, model G996U, with 128GB storage and 8GB RAM. Only condition and color differ.
Which one should I buy?
Buy the cheaper one. If prices are close, take the factory-unlocked black unit unless you specifically want violet.
Is a restored Grade A phone risky?
Grade A means minor cosmetic wear but full function. Check the return window and battery health before you commit.
How long will the S21+ keep getting updates?
Samsung's four-year window for the S21 series ends around early 2026, so security patches are near the end.
Does the S21+ still hold up in 2025?
Yes for daily use. The Snapdragon 888, 120Hz OLED and 8K video are still capable, but the 4,800mAh battery will have degraded on any used unit.
Does either come with a charger?
Product A includes a charging cable but no wall adapter. Samsung stopped shipping adapters with the S21 series.
