2-minute Review [Positives]
  • Excellent build quality
  • Premium, high-end aluminum unibody design that gives the phone a truly elevated aesthetic compared to its predecessors
  • Super sleek at 7.35mm
  • Chamfered details around the display and charging port catch and reflect light to add to the looks
  • OnePlus' useful notification toggle is carried over from the previous OnePlus device, and is handy as ever
  • Bright, sharp AMOLED display
  • Oxygen OS UI keeps things nice, simple, and close to stock Android, is quite stable, and adds useful touches like the "shelf" homescreen, as well as handy customization options for power users - overall it works very well, and doesn't include any bloatware
  • Breathtaking, and flagship-beating performance backed by powerful hardware and an astounding 6GB of RAM
  • Excellent heat management - the phone doesn't get hot even when put under high stress levels
  • Very good camera, that compares well with the top flagship phones
  • Camera interface is fast, minimalistic, and intuitive
  • Support for 4K video, as well as time-lapse and slow-motion movies
  • Front camera is excellent too
  • Good battery life that is helped by good software optimizations - lasts the whole day even with heavy use
  • Super quick charging battery (OnePlus calls it "Dash Charging") that can completely charge the phone from 0 to 100% in a little more than 1 hour, beating other "quick charging" phones by a good margin
  • Incredibly fast and accurate fingerprint sensor
  • Decent loudspeaker, with good volume levels
  • Excellent audio quality via headphones
  • On the whole, the OnePlus 3 is easily one of the best and most well-rounded Android phones ever made, and the fact that it manages to be so at a price well below current flagship devices, makes it nothing short of exceptional
  • Decent design and build quality (though it's plastic - would have been nice to see a metal or glass design)
  • The Samsung Experience UI skin on top of Android is a pretty decent skin and packs a lot of features - there’s Bixby, Face Recognition, which works fine and there are features like themes, game launcher, Samsung Pay mini, Samsung Cloud, games launcher, one handed mode and more
  • Decent dual camera setup on the rear - especially in proper lighting conditions, the camera takes good images, and low-light performance is not too bad either
  • Decent front camera too - captures generally good images with natural colors
  • Good call quality, with good noise cancellation
  • Good battery life - even with heavy use, you should end up with 30 percent battery by the end of the day
2-minute Review [Negatives]

No Major Negatives!

  • The tall, 16:9 AMOLED display on the Samsung Galaxy J8 is pretty decent, but could have had better resolution
  • The display also has significant bezels, whereas a lot of modern phones with tall displays these days have very little bezels
  • Average performance considering the price bracket, thanks to the budget Snapdragon 450 at the core, which is these days more commonly seen in phones under Rs 10k - while day to day performance is alright, but push the phone a bit and it will start to stutter - moreover, the Samsung Experience 9.0 has a ton of unnecessary and sluggish animations, that don't help
  • The dual rear camera setup is decent, but the portrait mode is pretty mediocre, with very ordinary edge detection - the blurring feels mostly unnatural
  • Uses the old micro-USB standard instead of a modern USB Type-C port
  • No fast charging support
  • On the whole, the Samsung Galaxy J8 is hard to recommend - the likes of Redmi Note 5 Pro and ZenFone Max Pro bring faster processors, better displays and more premium designs
