  • Versatile triple camera setup 
  • Improved camera performance.

  • Comes with no charging adapter or headphones inside the box
  • Plastic back is a bit odds with the upmarket glass designs 
  • Flat screen lacks a premium vibe.
  • No generational advancements in the camera department – lack of AF in the ultra wide is a flaw in particular
