Recently, Samsung announced that the Galaxy S3 has surpassed sales of 20 million units within the first 100 days of its launch. Now the latest news from Samsung claims that sales of Galaxy S3 can reach as high as 30 million units for 2012.

Samsung released its flagship smartphone Galaxy S3 in May this year and the phone appealed to smartphone enthusiasts and tech pundits alike. The Android-powered Galaxy S3 has proven to be a tough rival in the arena when the smartphone outshined Apple's iPhone sales in August.

The Galaxy Note 2 was launched at the IFA event in Berlin and is expected to hit shelves in October this year. The follow-up to the original Note is also expected to hit sales of 20 million units, claims Samsung's IT and mobile unit chief Shin Jong-Kyun.

Shin further indicated that the Galaxy Note 2's sales figures are likely to be double of its predecessor the Galaxy Note, which has sold more than 10 million units worldwide.

Along with an improved design the Galaxy Note 2 sports a 5.5-inch display which is slightly bigger than the original Note's 5.3-inch display. Keeping pace with current market demands, the Galaxy Note 2 will also include a powerful processor and a bigger on-board storage option than the previous version. A 2500mAh battery of the Galaxy Note will give way to a more powerful 3100mAh battery in the Galaxy Note 2.

Many phablet enthusiasts may have hoped for a 12-megapixel camera in the new device; however, the Galaxy Note 2 will boast an 8-megapixel camera, the same as Galaxy Note.

Samsung Galaxy S3 has already reached a milestone by crossing sales of over 20 million units. With high-end specs on-board the Galaxy S3, coupled with recent introduction of four new color variants, a 30 million sales mark may not come as a surprise. Moreover, with the increasing popularity of phablets and enhancements introduced to the Galaxy Note 2, the sales estimation of 20 million may seem realistic.

The much-awaited iPhone 5 is on its way to the market to challenge Samsung's dominance, time will tell if the Korean tech giant has made a correct sales forecast for the Galaxy S3 and the Galaxy Note 2.
