Samsung has recorded more than 30 million sales of their flagship Galaxy S III smartphone according to a recent post on the company’s Polish Twitter account. The message was accompanied by a photo showing some Samsung employees celebrating the achievement.

The Korean electronics giant managed to sell 20 million units within the first 100 days of the phone going on sale. That of course translates into roughly 200,000 handsets being sold each day as of early September.

At that time, Samsung correctly predicted they would surpass the 30 million mark by the end of this year. But as we sit with nearly two full months left in 2012, I’m not sure anyone could have anticipated they’d reach that goal in such a short amount of time.

It’s anyone’s guess as to how many more Galaxy S III handsets Samsung will sell through the remainder of this year with the holiday season in tow. Several new handsets including Apple’s iPhone 5 and Nokia’s line of new Lumia smartphones running Windows Phone 8 are sure to offer stiff competition.

Samsung’s own just-released (in the US) Galaxy Note II is also expected to be a top seller over the next two months, potentially cannibalizing sales of the S III. The massive 5.5-inch Note II is more expensive than most other phones, however. Most providers are offering it for $299 with a two-year commitment while the Galaxy S III and other popular phones can be had for just $199 or less on contract.
