The UnboxingTN Verdict

out of 100

A powerful phone with an excellent AMOLED display and capable cameras, held back by its modest battery and dated USB 2.0 connection.

What is good

  • Snapdragon 855 delivers strong performance
  • 6.39-inch Super AMOLED display with 1080×2340 resolution
  • 48 MP main camera and 20 MP selfie camera

What is not

  • 4000 mAh battery is a clear endurance weakness
  • USB 2.0 limits Type-C transfer speeds
  • 191 g weight adds noticeable heft

  • Performance 73
  • Camera 71
