Google and Apple are the main players in the smartphone business, and in case you aren’t convinced about that, there’s a new study looking into Android and iOS sales in the Christmas quarter to prove it.

Analyst firm Strategy Analytics has looked at smartphone shipments for the fourth quarter of 2012 and found that over 92% of them were Android and iOS devices.

According to the company’s estimates, 152.1 million Android handsets have been shipped during the period compared to 80.6 million in Q4 2011. When it comes to the iPhone, Apple has sold 47.8 million iOS smartphones in the fourth quarter of 2012 compared to 37 million a year before.

In total, out of 217 million smartphones shipments during the Christmas quarter, 199.99 million were Android devices and iPhones.

Compared to Q4 2011, Android has grown from 51.3% to 70.1% when it comes to global smartphone OS market share for the period, while Apple dropped a few points from 23.6% in 2011 to 22% in Q4 2012. That’s even if Apple sold almost 11 million more iPhones in Q4 2011 than in the year ago quarter, with Android’s growth being one very likely reason that explains Apple’s slight drop.

Overall, for 2012, Android is seen at 68.4% and iOS at 19.4% in the smartphone OS ecosystem, both up from 48.7% and 19.0%, respectively, for 2011. Despite impressive growth, especially for Android, the growth in the smartphone business as a whole went down from 63.8% in 2011 to 42.7% in 2012, “as penetration of smartphones began to mature in developed regions such as North America and Western Europe. “
