The Galaxy S4 rumor has been picking up quite a lot of steam lately, with the device featured in a variety of pre-launch reports.

A few weeks after that, around April 15, the handset could hit stores, although these details are yet to be confirmed.

Now, South Korean publication Money Today suggests that Samsung is preparing to move as many as 10 million Galaxy S4 units per month, which will make the handset the most popular Android device ever.

Its predecessors, especially the Galaxy S3 and Galaxy S2 models, enjoyed great sales to date, although incomparable with iPhone sales during the same periods of time. Nevertheless, no other Android device out there is able to boast similar sales numbers: the Galaxy S3 passed 40 million sales recently, while the Galaxy S2 also topped 40 million units, but in a much longer period of time.

So how does Money Today know in advanced how many Galaxy S4 handsets Samsung wants to sell each month? Apparently the publication has learned that the giant corporation has ordered each of its subcontractors to provide 10 million components per month, but don’t expect any of them to confirm such numbers.

Overall, Samsung wants to sell over 500 million phones this year, with 350 million of them being smartphones.

Moreover, the company plans to launch a variety of tablets in 2013 when it comes to screen size: 7-, 8-, 10-, 12- and 14-inch models are rumored, although it’s likely that not all of them will be running Android.
