Samsung has said that its critically acclaimed Galaxy S II Android handset has passed the 20 million sales mark.
The Korean firm launched the S II 10 months ago and it quickly emerged as the main challenger to Apple's iPhone in terms of usability and commercial success.
The S II has been the most successful device out of the entire Galaxy smartphone and tablet ranges. The device went a long way towards helping Samsung make $3.4bn in profit during its most recent financial quarter.
Despite the impressive sales of the Galaxy S II, Apple still leads the race when it comes to the high-end smartphone market.
Apple shifted a phenomenal 37 million iPhone 4S handsets in the last quarter alone, compared to 36 million sales for Samsung's entire Galaxy range during the same period.
However, the Galaxy range generated total sales of 300 million during the course of 2011.
Analysts expect Samsung to outperform Apple during 2012 as the Galaxy S II remains an attractive purchase.
The device is set to be upgraded to the Android 4.0 Ice Cream Sandwich platform that will enable it to compete with newer Android devices, and the pricing is expected to drop when the Galaxy S III is released.
Samsung was expected to unveil the highly anticipated Galaxy S III at Mobile World Congress, but the firm has no plans for a press conference.
The S III is now expected to be launched at a dedicated event, similar to how Apple makes product announcements. No specifications have been confirmed, but the handset could boast a 1.8GHz quad core processor, a 5in display with 2560x1600 resolution.
