Android will further solidify its market leadership in the smartphone operating system race in 2013, thanks to a broad support from smartphone vendors and the rollout of a wide range of low-priced models for sale in emerging markets. Shipments of Android phones are expected to top 600 million units or over 70% of global smartphone shipments in 2013, Digitimes Research estimates.

iOS will trail Android to take the number two position in the OS ratings with a 20% share, while other smartphone platforms will share the remaining 10%.

Shipments of Windows Phones, including 7.x and 8.x models, will grow 150% on year to 52.5 million units in 2013 for a 6.1% share, followed by RIM's BlackBerry devices with a 3.7% share, Digitimes Research estimates. Other platforms, including Tizen and Firefox, will take up a portion lower than 1%.
