2-minute Review [Positives]
  • 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
  • Well built
  • Quite good at heat management - doesn't heat up even when put under a lot of stress
  • Decent camera
  • Great battery life (can easily last over a day)
  • Useful "Ultra Power Saving" mode
2-minute Review [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
  • Looks cheap and utilitarian, compared to the much more premium designs of its competitors
  • The dimensions are a tad too big, at least for people with small hands
  • Display on the J7 falls short of expectations - colors are a little off, it's a bit on the dim side, and lacks an auto-brightness setting
  • No Gorilla glass protection on the display
  • Overall performance is good, but the phone is still underpowered compared to its top competition
  • Average camera
  • Loudspeaker is not particularly loud, and having it on the back makes it cumbersome still
  • No fingerprint sensor
  • Also lacks notification LED, gyroscope and a magnetometer or magnetic sensor
