Other notable software tweaks on the S4 include the Smart Pause, however, due to the crowded nature of the event at which I was using the phone, it was hard to work out how accurate and responsive these features are — there was pretty much always someone looking at the screen.
However, I had more luck with the Air Gesture feature introduced for the Galaxy S4 which uses sensors at the top of the handset to detect when you are trying to scroll through things. For example, if you want to scroll through pictures in your album or different music tracks in your collection, you just need to swipe your hand left or right in front of the handset and it will move along to the next item.
Obviously, for this to work you need to be relatively close to the phone but it'll still work from a few inches away.
On the rear of the phone is a 13-megapixel camera with flash and on the front is a 2-megapixel affair for still and video calling.
However, Samsung has gone the extra mile with the camera and included a number of software tweaks to give more mode choices to users.
In contrast to a number of other handset makers, the outside of the chassis on the S4 is home to only a power button and volume rocker.
One of the new camera modes is called Dual Shot and uses both the front and rear cameras to take on photograph that includes the scene in front and behind the camera.
In the image above the front-facing camera was providing the main part of the picture (the Samsung demonstrator is on the left hand side and I'm next to him with the camera) while the inset heart is showing another member of the Samsung team stood in front of the device. Naturally, having the inset picture in a heart is a user-definable option.
