Our take on the Samsung Galaxy A21 A215U Unlocked Smartphone (USA Version)

The Galaxy A21 is a budget Samsung phone with a 6.5-inch HD+ Infinity-O display, a quad rear camera led by a 16MP main lens, and a 4,000mAh battery. It runs on the Exynos 850 with 3GB of RAM and 32GB of storage, expandable up to 512GB via microSD. It suits buyers who want a large screen and Samsung software for basic use, but its HD+ resolution and modest chipset trail rivals like the Moto G series and Redmi Note line. Owners like the battery life and screen size; reviewers say it feels slow under load and the display is soft for its size.

Questions and answers

Is the Galaxy A21 good for gaming?
Only for light games. The Exynos 850 and 3GB of RAM handle simple titles, but demanding 3D games stutter at low settings.
Does it support 5G?
No. The A21 is a 4G LTE phone only.
How much storage can I add?
It has 32GB built in and a dedicated microSD slot that takes cards up to 512GB.
Is the display sharp?
It is a 6.5-inch HD+ panel, so text and icons look softer than on 1080p phones of the same size.
What is in the box?
The phone, a charger, a USB cable and a SIM ejector tool. A case and screen protector are not included.
Is it a good upgrade from an older budget phone?
If your current phone is several years old, the bigger screen and battery are clear steps up. If you want speed, a Moto G or Redmi Note gives more for similar money.
