2-minute Review [Positives] N/A
  • 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] N/A
  • 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
