  • From the sides, the phone has sharp edges that will dig into your palms, which can make it uncomfortable to hold over long periods of time
  • The Windows Phone platform continues to suffer from a limited app selection, when compared to Android, or iOS
  • Large size makes it a bit uncomfortable for one-handed use
  • Lacks ambient light sensor
  • Second SIM slot can be used either for the second SIM or SD card, but not both
