2-minute Review [Positives]
  • Beautiful, all-metal, understated design
  • Despite featuring a 5.5-inch screen, the ZenFone 3 Laser fits relatively easy in one hand
  • Good full-HD IPS display - good color reproduction, rich blacks, good brightness level, decent sunlight legibility, wide viewing angles
  • ZenUI interface has improved over time and the latest version is lighter, cleaner, and uncluttered
  • Good overall speed/performance
  • Decent rear camera - has a fast (laser) focus, captures good amount of detail, and has decent colour reproduction
  • Does decently well with low-light conditions too
  • Video recording performance is also good with the electronic image stabilisation (EIS) feature coming in handy
  • The front camera is also decent and takes selfies quickly
  • Fast, accurate fingerprint scanner
  • Bundled earphones are decent for music quality with minimal distortion at higher volumes
  • Decent battery life - lasts the day with moderate use
  • Striking, flamboyant glass-and-metal design, with strong attention to detail
  • Great build quality
  • Very good display with a comfortable viewing experience both under the bright sun and indoors
  • Good speed/performance in daily use
  • The new Qualcomm processor is quite efficient in keeping the temperatures under check
  • Camera is decent overall average and a bit of an improvement from the Zenfone 2 series last year
  • Decent battery life, which is helped by an efficient processor - lasts a full day
  • Fast fingerprint scanner
2-minute Review [Negatives]
  • The edges of the Micro-USB port and the two screws on the bottom are a bit sharp
  • The display is a fingerprint magnet and you will need to clean it from time to time
  • Although the UI itself is light, the phones comes loaded with plenty of bloatware including Asus's own apps like Themes, Photo Collage, Mini Movie, ZenCircle, ZenSync, Weather, Do It Later, Game Genie, ZenFone Care, and Cover
  • The ZenFone 3 Laser, unlike other ZenFone 3 smartphones, doesn't support fast charging
  • The overall speed/performance is strictly middling and falls significantly behind other top phones at this price level
  • Average loudspeaker
  • Lacks fast charging support
  • Because of the glass-based panels, the surface is prone to finger prints and smudges
  • The concentric circle design may be too shiny for some
  • Asus' ZenUI is pretty bloated, with a lot of unnecessary apps, leading to a cluttered experience
  • Although day to day performance is good, there are visible lags on heavy games like Asphalt 8
