2-minute Review [Negatives]
  • BlackBerry OS 10 is not as simple or intuitive as Android/iOS/Windows phone, and takes quite a bit of time and effort to get used to
  • The gesture centric UI means that you have to move your thumb quite a lot over the large screen which takes longer and requires more effort than a simple button press would have
  • BBM today simply isn't the powerful draw it once was, with a plethora of messaging apps around
  • Voice search and command features aren't as capable as Apple's Siri or Google's voice search
  • Phone internal storage is not accessible from a PC without using BlackBerry's included desktop software (only microSD card is accessible)
  • Average camera
  • Occasionally laggy performance
  • Built-in speaker is pretty loud and works well for voice, but music is just too thin and tinny
  • Low screen resolution means the video watching experience is not that great
  • Windows Phone app ecosystem continues to lag behind Android and iOS
