2-minute Review [Positives]
  • 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
  • Compact, smart looking, premium design with a metal build - very similar to the Redmi Note 3, but more easy to handle (because of the smaller size)
  • Excellent ergonomics, with the curves on the back making the phone very comfortable to hold
  • Light-weight with an excellent weight distribution, despite the large battery it holds inside
  • Nice, vibrant, and bright display, with excellent touch-responsiveness, and good viewing angles
  • MIUI is a one of the better Android skins around
  • Very good speed/performance - one of the best in this price range
  • Decent camera
  • Excellent battery life - easily lasts a day and a half in regular use
  • Good audio quality
2-minute Review [Negatives]
  • 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
  • Camera is decent, and almost at par with the more expensive Redmi Note 3, but still could have been better, especially with low light performance
  • Loudspeaker volume could have been better
