The UnboxingTN Verdict

out of 100

The Note 40X combines generous memory, 5G, and smooth 120Hz display, but slow charging, heavy weight, and XOS refinement hold it back.

What is good

  • 12GB RAM and 256GB storage provide generous everyday capacity.
  • 5G and Bluetooth 5.3 deliver modern wireless connectivity.
  • 120Hz IPS LCD keeps scrolling smooth at 1080 × 2460.

What is not

  • 18W charging is slow for a 5000mAh battery.
  • 201g weight makes the 8.3mm phone feel relatively hefty.
  • Android 14 with XOS 14 offers limited software refinement.

How the score breaks down

  • Performance 52
  • Display 45
