Blackberry's overall smartphone OS market share in Q4 2016 was 0.0481 percent. According to research firm Gartner, the smartphone company only sold 207,900 units out of about 432 million units sold worldwide.

According to the Gartner Q4 2016 report, it did not include the smartphone's handsets that run Android. However, even if the Android handsets were included, the total number of units sold was still low. When compared to the Q2 2016, the number has dropped as the company sold about 400,000 units. In the Q3 2016 report, the smartphone's operating system showed a global market share of 0.1 percent. Its equivalent was 377,800 devices sold during that period.

Alex Thurber, senior vice president of global sales, said that the company would still invest in its mobile operating system BB10. The company did not release any phone running BB10 OS. "BB10 has a strong following around the world in enterprise and government, as well as consumers in particular markets. I want to make sure that our customers and users don't get concerned that we're not continuing to support and invest in BB10 because we absolutely are," Thurber told the Financial Post.

Google dominated the OS sales as the company sold 352.7 million smartphones running Android. The company's global market share was 81.7 percent. Apple iOS was ranked in second place for its market share of 17.9 percent. Apple sold 77 million units in Q4 2016.

In Gartner's worldwide smartphone sales to end users by vendor., it showed that Apple sold 77,038 million devices having a market share of 17.9 percent. The company ranked number one in this category. However, the report showed that there was only 256,000 units difference between Samsung that ranked in second place.

Samsung sold 76,782 million devices with a market share of 17.8 percent. Samsung's Q4 2015 report showed that it sold 83,437 million devices. "This is the second consecutive quarter in which Samsung has delivered falling quarterly smartphone sales. Samsung's smartphone sales declined 8 percent in the fourth quarter of 2016 and its share dropped by 2.9 percentage points year on year," Anshul Gupta, research director at Gartner, said.

Gupta said Apple achieved the strong sales in Q4 2016 because of iPhone 7 and iPhone Plus. It also benefited from the mature markets in North America, Western Europe, Asia, Australia and South Korea with a weakened demand on Samsung handsets.
