The OS, going by the name "Ice Cream Sandwich," is being emphasized by Samsung as the main attraction of the 7-inch tablet, with "improved Android OS features" and strong multimedia and communication capabilities, eweek.com reported Monday.
The tablet will be available in both 3G and WiFi versions, containing a 1GHz dual-core processor and 1GB of RAM.
The Tab 2will allow users stream multimedia content to PCs, other Samsung smart devices or third-party Web storage.
It will also offer the ability to place a call "as easily as a phone," and can manage multiparty video calls, Samsung said.
Tablets are growing in importance in the electronics segments, analysts said.
A Jan. 31 report from research firm Canalys, which folds tablet sales into PC shipment totals, said tablet sales helped the global PC market to grow 16 percent during the fourth quarter of 2011.
If tablets were removed from those figures, the report said, the market would have instead declined year-over-year by 0.4 percent.
While prices for the Galaxy Tab haven't officially been announced, experts estimate the WiFi model will sell for $450 and the 3G for $556.
