2-minute Review [Positives]
  • Well built
  • Ergonomically sized, comfortable for one-handed use
  • Fingerprint scanner at the back is easy to reach, and quite responsive
  • Useful physical button that can be setup to to play/ pause music, switch tracks, or launch a custom app
  • Decent Full HD display with Corning Gorilla Glass 3 for protection - viewing angles are good and colour reproduction is decent
  • Stock Android UI keeps thing nice and simple, and will be much appreciated by Android enthusiasts
  • Good all-round performance backed by solid hardware - multitasking is easy with several apps running in the background, and games run well too
  • Decent dual-camera setup on the rear - decent bokeh shots (as long as you set it up right), good macros, and indoor shots are also pretty good
  • Decent front camera too - photos taken with the the front camera are good and can be used on messengers and social networking apps - also, the front flash is handy in dark areas
  • Very good battery life - the phone can run for a day and a half with regular use
  • Pretty decent charging speed - takes about 2 hours to charge fully
  • Dedicated slots for dual SIM cards and memory card (which is a always a good thing when many other phones are choosing to come out with a hybrid SIM/memory slot)
  • On the whole, if stock Android and good battery life appeal to you, then the Lenovo K8 Plus is a good choice
  • Top-notch build quality
  • The polished all-metal back of the Redmi 4 makes this phone look more premium than its predecessor (and actually more similar to the more expensive Redmi Note 4)
  • Compact, and quite usable with just one hand - fits well in the hand
  • Fingerprint sensor works well, and is conveniently located
  • Nice 5-inch HD (720x1280) IPS display with 2.5D curved-edge glass - bright, sharp, and with decent viewing angles
  • Xiaomi's MIUI skin is one of the more refined Android UIs - it is clean, polished, and has a bunch of added functionality - Dual Apps, Quick Ball, One-handed mode, Child Mode, Second Space
  • Decent overall performance - on par with those of other phones powered by the Snapdragon 430 series processor
  • Good video playback performance
  • Nice attention to detail overall - such as a protective ring around the camera lens
  • Decent rear camera - a definite improvement over the Redmi 3S - is quick at focusing, and images are fairly detailed and sharp
  • Video recording at 720p and 1080p is decent too
  • Decent front camera - pictures taken in good light have a good amount of detail and decent colour tone
  • Decent call quality
  • Good audio quality
  • Excellent battery life - with moderate use, lasts up to 2 days - there are also power saving modes to help squeeze more life out of each charge
2-minute Review [Negatives]
  • A bit on the thick and bulky side, measuring 8.99mm and weighing 165g
  • Sunlight legibility of the display could have been better
  • Rear camera is pretty good but could have been a bit better in landscape mode, and with HDR
  • Also the camera tends to sometimes lag a bit in depth (bokeh) mode
  • Camera performance is improved, but ordinary low-light shots and slow processing in HDR mode still leave something to be desired
