Smartphones based on Google Android could challenge the dominant position of Apple's iPhone if it continues its current rate of growth.
In the past year, Android has spread from one device on one carrier to 12 handsets on 32 carriers in 26 countries, according to the Financial Times.
These numbers are to be boosted even further with more smartphone makers planning to introduce Android-based devices and more carriers set to support the Android operating system.
Android appeals to smartphone makers seeking to challenge the dominance of Apple, Nokia and Research in Motion, which comprise an 80% share of the global market.
Smartphone makers HTC, Motorola and Samsung have announced plans to release Android-based devices in the US soon and carriers Sprint and Verizon Wireless are to join the Android fold.
Google is targeting the iPhone's lack of real keyboards; inability to run simultaneous apps; inability to allow open development; and lack of interchangeable batteries.
Google chief executive Eric Schmidt stepped down as an Apple director in August because of growing conflict of interest between the two companies, as Android becomes more mainstream.
