The Canadian firm said its would begin selling "Priv," describe as "a flagship handheld device that will run on the Android operating system with BlackBerry security," expected to be available later this year.
"Priv combines the best of BlackBerry security and productivity with the expansive mobile application ecosystem available on the Android platform," said John Chen, executive chairman and chief executive.
BlackBerry said however it "remains committed to the BlackBerry 10 operating system, which enables industry-leading security and productivity benefits."
The company said it "will continue to develop and enhance the BlackBerry 10 operating system and is confirming plans to release platform updates focused on security and privacy enhancements," in March 2016.
The BB 10 operating system was unveiled in 2013 as part of an effort to regain market share lost as consumers around the world shifted to devices running on Google Android and Apple's iOS. But the operating system share has fallen further, and now represents less than one percent of smartphone users.
BlackBerry, one of the early pioneers of smartphones, has been struggling for years. It has made several efforts to find new customer niches, with low-cost devices, tablets and by shifting its emphasis to software and services.
In releasing its quarterly results, BlackBerry said it swung to a profit of USD 51 million for the three months to August 29, compared with a loss of USD 207 million in the same period a year ago.
"I am confident in our strategy and continued progress, highlighted by our fourth consecutive quarter of year-over-year double digit growth in software licensing revenue and sixth consecutive quarter of positive free cash flow," Chen said.
