2-minute Review [Positives] N/A
  • Modern, fresh design with an almost bezel-less ‘Infinity Display’
  • Good build quality
  • The rear is made of polycarbonate and feels nice
  • Despite housing a 5.6-inch screen, the device is compact and lightweight - you can easily use it with one hand
  • The 5.6-inch HD+ Super AMOLED ‘Infinity Display’ is one of the best in this price range - makes for a good video watching experience - the AMOLED panel makes every thing look vivid and the viewing angles are decent too
  • Samsung's Touchwiz on top of Android is one of the more refined and neat Android skins, and has some useful add-ons like Samsung Pay Mini which makes digital payments easy and a Knox-powered ‘Secure Folder’ for you store to sensitive files
  • Decent day-to-day performance, backed by a Exynos 7870 - should work fine for basic users
  • Good battery life - the 3000mAh battery which will easily last a day for heavy users while average users can squeeze around 36 hours of battery life
2-minute Review [Negatives] N/A
  • The display resolution could have been better
  • Misses out on basic sensors like an ambient light sensor, and a digital compass
  • The performance is alright, but is far from the best in this price bracket (that prize would go to the likes of Xiaomi Redmi Note 5 Pro)
  • Average rear and front cameras - colours in daylight photos are washed out, and dynamic range is below average - even close-up shots are ordinary, with bland colour reproduction
  • No fast charging support
  • On the whole, the On6 is a fairly underwhelming device, and you will find plenty of better alternatives available at the same price point
