The UnboxingTN Verdict

out of 100

A powerful camera phone with an exceptional display, but its heavy body, dated Android 10 software, and limited 4G connectivity hold it back.

What is good

  • Snapdragon 865 and Adreno 650 deliver strong performance.
  • 108 MP main camera, 4x optical zoom, and OIS impress.
  • 6.9-inch Dynamic AMOLED 2X panel reaches 120Hz and 1400 nits.

What is not

  • 220 g body makes the phone noticeably heavy.
  • Android 10 is now dated.
  • 4G cellular limits mobile-network capability.
