At the annual Mobile World Congress in Barcelona, the smartphone is king.

"The smartphone is getting more powerful, more connected to all the things you might have at home or with you".

So, move over home computer-smartphones are taking the lead in allowing us to control the Internet of Things, or IOT for short.

"IOT, it's a buzz word, but what it really means is your smartphone becomes the center of not only your mobile life on the go, but of everything within your home."

And the number of those smartphone-connected devices is rising, from electric toothbrushes to home robots equipped with cameras, lasers and a range of sensors.

Another area seeing improvements is smartphone cameras.

Some are capable of changing focal length, while others keep the image sharp at all times or offer 360-degree vision.

"So when you are at the bar, it is easier to fit more people in your selfie."

Samsung's Gear 360 camera, with front and back lenses, will connect with the company's phones and the Gear VR headset.
