"Applications are starting to talk to each other to make the user experience better," said Saadi.

The Galaxy S III also inherits a number of features from the Galaxy Note, including Facebook and Twitter accounts updated in real-time on the home screen, which has helped make the Galaxy Note a success, according to Saadi.

"Samsung has added some clever bells and whistles on to the phone like S Voice and image recognition, but without using the phone its difficult to say how well it works," said Wood.

But luring users with software isn't always easy. Many of the new software features are a boon for advanced users who are enthusiastic about technology, according to Saadi. However, getting the message across to a typical user is really hard, he said.

The Galaxy S smartphones have been criticized for a design that is not luxurious enough. The new Galaxy is also made of plastic, but that is an improvement over the previous models, according to both Wood and Saadi.
