The UnboxingTN Verdict

out of 100

The Galaxy A21s offers versatile cameras and useful connectivity, but its display, battery endurance and software age it.

What is good

  • NFC and Wi-Fi 5 provide practical wireless connectivity.
  • Dual-SIM support and USB-C add everyday convenience.

What is not

  • 720×1600 display offers modest 270 ppi sharpness at 60 Hz.
  • Exynos 850 and Mali-G52 MP1 provide only modest performance.
  • 5000 mAh battery is less competitive among recent category devices.
