Samsung's own branded Hub is still present on the handset, but instead of offering different Hubs for music, books, films and games, they are now all found in one place, making it much more convenient to access your content.
The music service 7Digital will continue to provide the musical element of Samsung Hub as it has done in previous generations of Samsung's Galaxy S devices. It also provides the store for BlackBerry Music.
Another notable feature found on previous generations of Galaxy but evolved for the S4 include Group Play for music, photos and games.
This feature allows multiple people to view or listen to the same content in real-time by sharing it between handsets without the need for a mobile or Wi-Fi signal using Wi-Fi Direct connectivity.
Connecting up two phones to play music creates a stereo set up and this can be increased (if there are enough handsets in the room) up to creating a 5.0 surround sound set up. The image above shows a two speaker stereo setup.
By now there should be a pattern emerging: while the Samsung Galaxy S4 looks a lot like the S3 on the surface, Samsung has put considerable efforts into enticing customers to stick with the brand through custom software on the devices.
Another of these tweaks is the Samsung Health app that allows you to track calories consumed and calories burned. However, rather than restrict you to items on a pre-populated list, you can add to your Health tracker by inputting custom items, either by text or by taking a photo using the phone.
There are lots more of these little touches throughout the handset such as S Translator or the 'Story Album' photo mode, adding value to the core Android Jelly Bean OS proposition.
Overall, because I'm not a fan of overly large screens that border on the phablet category, so I was ready for disappointment with the Galaxy S4. However, with the chassis actually taking up less room in your hand than the previous generation and a number of innovative, if somewhat gimmicky, software tricks on board, the S4 looks set to make its mark on the Android market.
