2-minute Review [Positives] N/A
  • Attractive, sturdy, unibody design - easily one of the better looking devices in this price bracket - build quality and materials are flagship-grade
  • Very good sAMOLED display, arguably the best in this price bracket - high resolution, good viewing angles, good colour reproduction - videos look excellent - and sunlight legibility is great too (on par with more expensive phones, and better than Samsung's own Galaxy J7 Max in this price bracket)
  • Decent performance in day-to-day use
  • Samsung's UI over Android is light, and works well - with some nice add-ons like social camera, and Samsung Pay
  • Good rear camera - pretty similar to the one on the very good J7 Max - making it one of the best cameras in this price bracket - and a good shooter even for low light situations
  • Very good audio output from both headphones, and loudspeaker
  • Very good battery life - among the best in this price bracket - will comfortably last the day even with heavy use
  • Fairly ergonomic too
  • Separate slots for Dual SIMs and SD card (instead of a hybrid slot)
2-minute Review [Negatives] N/A
  • If design, battery life and brand name are the main criteria then the Galaxy J7 Pro is a good choice, but it has some tough competition from the likes of OnePlus 3T (more powerful + more dependable camera), and Moto G5S Plus on the lower end (almost as good in all criteria, at a lower price)
  • Performance could certainly have been better, and while its good enough in daily use, it's not quite what you would call snappy, and it doesn't match up to its top competitors - so, if your only use case is casual social networkings, emails, videos - then the phone will do fine, else there will be better options in this price bracket
  • While the rear camera is pretty good, it does sometimes take too long to focus, and sometimes underexposes pictures, and that takes away from the dependability a little bit
  • Front camera is good too, but it is focused a bit too close, which can lead to blurry shots when the phone is held a bit far
  • No support for fast charging
