Editor's Note [Positives]
  • Very good build quality
  • The metal frame is a nice touch, and enhances the overall design
  • Comfortable to hold, for a phone of this size
  • Very good display - offers vibrant color output, good sunlight legibility and good viewing angles
  • Lenovo's UI over Android is one of the better UI skins around
  • Good speed/performance in daily use (although gaming performance could have been better)
  • Good overall front and back cameras
  • Thanks to Dolby Atmos, Wolfson WM8281 audio codec and dual front-facing speakers, loudspeaker output is brilliant and clear even in full volume
  • Audio output through headphones is brilliant as well
  • Good fingerprint sensor
  • Good battery life
  • VR support
  • Nice, premium, polished design
  • Sturdy build quality
  • Given its large size, the weight is quite manageable at 175g
  • Excellent display, perhaps the best at this price point, with great colors and vibrance
  • CynogenMod 12 allows deeper control on the display - you can tweak the colour temperature, and choose different temperatures for day and night
  • The CyanogenMod UI allows a bunch of customisations, that will come in handy if you are a power user, but retains a nearly-stock Android interface
  • The UI is smooth and stable too, and performs well
  • Very good, lag-free performance, even given the somewhat old processor, which indicates how well the software has been optimized
  • Good front camera for selfies
  • Good rear camera in well lit conditions
  • Decent fingerprint sensor
  • Very good battery life - can last over a day fairly easily
  • Very good audio quality
  • If you like modding your smartphone, and have been waiting for a CyanogenMod-powered phone worth buying, this is it
  • The Zuk branded phones are also the only Lenovo devices where rooting won't void the warranty
  • 64GB internal memory
Editor's Note [Negatives]
  • No major negatives
  • This isn't an ergonomic smartphone - it's quite wide, which puts single handed usage out of question
  • Rear camera could have been better under low-light conditions
  • The camera is also just a little slow in focus speed, compared to it's top competitors in this price range such as the Xiaomi Redmi Note 3
