The UnboxingTN Verdict

out of 100

The Galaxy A21 combines an AMOLED display with a light build, but limited performance, storage, and endurance reduce its appeal.

What is good

  • 6.5-inch Super AMOLED display delivers vivid viewing.
  • 150g weight makes the phone relatively easy to handle.
  • NFC and Bluetooth 5.0 provide useful wireless connectivity.

What is not

  • 3GB RAM and the 2020 Samsung platform constrain performance.
  • 32GB storage leaves limited room for apps and media.
  • 4000mAh battery is a notable endurance weakness.
