Contacting a friend with your smartphone will be mainly be two routes of communication: calling and messaging. When we think about both of these routes, we think of two applications to preform these tasks. To reach over to your friend, we can easily predict that a few button pressing. However, there is a pleasant surprise found in the Samsung Galaxy S. One simple swipe action regardless if you are on contacts or messaging (single conversation) will work! It is an incredible ease, especially if you need to switch between them over a burst of communication frenzy. [Flux: This alone would win me over to want this phone!]
Calling: Just swipe to the right!
Messaging: Just swipe to the left!
