Even the CEO of the company said, “We have a lot of problems”. He is absolutely right as almost every BlackBerry user has abandoned the phone and the OS. It is also worth mentioning here that BlackBerry was once the most successful company in the cell phone business. It stood where Apple stands today.
The main reason behind such a drastic downfall was the unavailability of apps. The UI of their OS was a bit too complicated for a new user to adapt as well. There were some loyal users but that too left BlackBerry for better and smarter options.
