worldwide sales figures for the smartphone category show Android in general at 75 percent of the market.
as a smartphone vendor, Apple is also in second place. for q1 Apple sold 18 million units. Samsung sold 30 million.
so by which of these measures is it the best selling phone?
these aren't my numbers, they are the Gartner Group numbers.
----------
the best way to kill sales of your current product is to announce a new model that isn't shipping for 3 months.
I'm not sure what your numbers mean because Apple sold 37 million iPhones in Q2 2013 and Samsung sold more than 30 million smartphones in that same period (I believe it's estimated at 64 million). However, that's all of Samsung's phones so not really a direct comparison.
