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.
