The news comes from the folks over at Oled-info.com who noticed a posting over at Samsung's Flickr feed.
One of the photos celebrating 1,000,000 sales is shown below with the rest at the Flickr link above.
The post accompanying the images states the following:
"Galaxy S 2 is literally selling like a hotcake in Korea! This Samsung's flagship smartphone released last month, and already has become a million-seller, just in a month. Samsung Electronics said on 30 May Galaxy S2 has reached the mark of 1,000,000 sold, which means it is sold every three seconds.
It has been breaking every selling record relating to cell phones in Korea. Since its release on 29th of April, Galaxy S2 passed 100,000 sold in 3 days, and 200,000 in 8 days, and reached 500,000 sold after a fortnight. This fastest 1,000,000 sold record, in particular, shortens its predecessor Galaxy S's previous record of 70 days.
The popularity of Galaxy S 2 is considered to be attributed to its 4,3 inch Super AMOLED Plus screen, HSPA+ 21Mbps, 8.9 slim design, along with its optimized environment for smartphone, and Samsung Electronics' customer-oriented O/S upgrades."
The Galaxy S II is clearly going to be a popular model for Samsung, with it and other premium dual-core Android handsets, along with Google, all doing their best to pre-empt whatever surprises Apple has in store for the iPhone 4S or the iPhone 5.
If you're looking for a new smartphone, it certainly has shaped up to be a good year, and clearly, the year's not over yet!
