We all knew that the Samsung Galaxy S III is an incredibly popular handset, but today the company gave us an idea of just how popular it is. The Galaxy S III has hit the 20 million sales milestone, which is pretty impressive. Even more impressive is the fact that the smartphone surpassed the 20 million mark only 100 days after launch.

To put that in perspective, the Galaxy S III’s predecessor, the S II, had only managed 5 million sales after 85 days on the market, and it took 5 months before sales climbed to 10 million. 10 million sales in 5 months isn’t anything to stick your nose up at either, which makes the Galaxy S III’s astronomical success even more noteworthy. That 20 million figure is, obviously, enough to make the Galaxy S III the most successful smartphone in Samsung‘s history, and the company told CNET that its success has been “record-setting.”

Samsung recently announced the Galaxy Note II at IFA 2012, the follow up to the original Galaxy Note, which was something of a surprise success for Samsung. Anticipation is high for the Galaxy Note II – so high, in fact, that the new phablet might be able to achieve similar success. It probably won’t reach the same sales numbers as the Galaxy S III, but it wouldn’t surprise us one bit to see Galaxy Note II sales soar above those of the original device.

Samsung is continuing to ride the Galaxy S III train as well, recently revealing four brand new color variants for the handset. All of this, and we’re only 100 days out from release. One thing is for sure: we can expect that number to rise quite a bit in the coming weeks and months, so don’t think this will be the last you’ll hear of the Galaxy S III’s success. Are you one of the 20 million people who has purchased a Galaxy S III since it released back in May?
