When the Samsung Epic 4G was announced it had plenty of the same features as the other Samsung Galaxy S devices, but in this video by Sprint hints on some of the features that set it apart from other Galaxy S devices on other carriers as well as the EVO 4G. This video encourages you to buy both but it shows specific reasons to buy the Epic over the EVO.
Shes shows features about how the EPIC brings as far as the super AMOLED display, the physical keyboard and the Epic’s media streaming is top-notch. Overall though it is up to personal preference as to which phone you prefer, you should just go in a store and experience which you will like, but it’s always interesting to see the carrier compare the phones.
