The next version of the Samsung Galaxy S phones will be released on Tuesday after two versions already in the market. However consumers who use the Sprint Nextel will see a lot of differences between the latest Epic 4G and others.

Over a million of the Galaxy S phones have been bought in the US alone in just 1 and half months and even with that, only the Captivate and Vibrant phones available on AT&T and T-Mobile which were made with Android OS were considered.

Even though the new iphone 4 sold 1.7 in three days, it was for 5 countries and the exact number sold in America wasn’t stated. There aren’t many differences between the Captivate and Vibrate except one or two appearance and no wonder the two are normally categorized as one in many reviews.

The Samsung Epic is the phone manufacturer’s first 4G phone on the American market and the second 4G phone on Sprint which is the only network carrier in the US with 4G capabilities.

4G phones are known for demanding powerful batteries and we are waiting to see how battery efficient the Samsung Epic 4G is. The smartphone has a fast access to the internet and has a slide keyboard as well as dual cameras for video chatting. It also has a camera flash which are absent in the other Galaxy S phones. It also sells for $250 which is higher than the other phones.
