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
  • Incredibly fast and accurate fingerprint sensor
  • Chamfered details around the display and charging port catch and reflect light to add to the looks
  • Bright, sharp AMOLED display
  • OnePlus' useful notification toggle is carried over from the previous OnePlus device, and is handy as ever
  • 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
  • Good battery life that is helped by good software optimizations - lasts the whole day even with heavy use
  • 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
  • Decent loudspeaker, with good volume levels
  • Excellent audio quality via headphones
  • 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
  • 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)
  • Has a new, modern 'infinity edge' 18:9 AMOLED display, that stretches from edge-to-edge, and makes the device easy to use with one hand
  • 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
  • Dolby Atmos surround sound
  • Very good battery life - the big 3500 mAh battery, combined with the low power Snapdragon 450 processor and a 720p HD+ display gives you a recipe for some very good battery life - the phone comfortably lasts a whole day and if you use it judiciously, you can even make it last for two days
2-minute Review [Negatives]

No Major Negatives!

  • No ambient light sensor, which is a big miss at this price point
  • Fingerprint & face recognition is on the slow side
  • While the display is pretty decent, it 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
  • Also lacks a notification LED
  • 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
  • The speaker is both oddly placed (on the right side of the phone) and tiny and cracks at higher volume
  • No fast charging support
  • No compass
  • Uses the old micro-USB standard instead of a modern USB Type-C port
  • 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, and now with the Poco F1 around the block, the J8 is an even harder sell
