MM Research does not count Symbian as a smartphone platform. This makes them inconsistent with any other analyst for counting smartphones. So shouldn’t Symbian be included?
In a comment to iPhone has 72% of Japanese smartphone market | Asymco it’s been pointed out that 12 million Symbian sold in the same time frame as Apple sold 1.7 million phones in Japan.
It would seem then that the correct market share for iPhone would be 12%, with Symbian having 83% and “others” having less than 5%.
Symbian in Japan is not the same thing as Symbian elsewhere. Symbian in Japan is used as a low level OS by Fujitsu, Sony Ericsson Japan, Mitsubishi, Sharp and others to provide devices running the MOAP(Symbian) software platform. MOAP (Mobile Oriented Applications Platform) is the software platform for NTT DoCoMo’s FOMA (Freedom of Mobile Multimedia Access) service.
Unlike Series 60 and UIQ MOAP(Symbian) is not a open development platform.
MOAP is also supported by Linux with Panasonic and NEC using it in something called MOAP(Linux).
MOAP(Linux) is also not an open development platform.
So the “72% share for iPhone” in Japan must be stated with this important caveat: that Symbian and Linux are not included because, due to not having exposed APIs, they are classified as feature phone platforms.
