During its Galaxy S6 launch event, Samsung specifically promoted the inclusion of preloaded mobile apps from Microsoft as something that differentiated it from competing Android phones. However, some American consumers who have bought the Galaxy S6 through their wireless carriers have found that some of these apps have been removed from the devices by their carriers, and it looks like Verizon in particular has been the most zealous about removing preloaded Microsoft apps from the Galaxy S6.
Carriers are removing some key Galaxy S6 features (i.e. DON'T buy a GS6 from these carriers!)
