It is 40 years since the first mobile phone call was made on April 3 1973. Here is a look back at how technology has evolved.
Has mobile innovation stalled? The lack of big headlines appears to suggest it has.
Samsung has unveiled its new Galaxy S4 - a phone with a 5-inch screen, a 13 megapixel camera and a function doubles as a TV remote.
More than 20 million passengers miss bus or train stops each year because of "digital distraction" from their smartphones, a study has found.
The problem has affected 51% of Britons and causes around 15% of commuters to run late for meetings, according to the findings.
Over the last year, passengers have missed their stops an estimated 29 million times, the report showed.
Londoners were found to be among the most preoccupied by their mobiles. Three in five (62%) of the capital's Tube, bus and train travellers said they missed a stop for this reason.
On average, Londoners miss two stops a year. A handful of commuters consulted for the study (3%) said they failed to disembark at an intended point more than 20 times in the last 12 months.

Mobile phones are making it increasingly difficult to rest in peace with almost a fifth of funerals interrupted by obtrusive ringing, according to research by The Co-operative Funeralcare.
A survey of 2,000 people found that two in five people do not turn their phone off during a funeral service and a small percentage of mourners refuse to turn down the volume.
One in 16 people admitted to accidentally receiving a message on their phone during a funeral while one in six said they had seen others trying to frantically turn off a ringing phone.
Examples included the tune If You're Happy And You Know It Clap Your Hands blaring as a coffin was lowered in South Wales and a vicar's mobile ringing as he gave a eulogy in North Wales.
A separate survey of 170 funeral directors by The Co-operative Funeralcare found that almost a fifth of funerals had been interrupted by mobile phones.
Privacy conscious phone users are being offered a new app that claims to be the world's first totally secure messaging service.
The new software, created by British company Redact, is able to send heavily encrypted messages from one iPhone to another without passing through any central servers.
The designers are so assured of the products effectiveness, they have offered a £10,000 prize for anyone who can crack its codes and intercept a message.

Certainly it looks like year-on-year growth was much higher for Samsung's mobile phone unit than for Apple's iPhone segment.
That's a testament to the broad appeal of Samsung's device range compared with the relatively high-end focus of the iPhone.
It's also helpful that Samsung has device launches throughout the year, which help to keep demand going on a more consistent basis, whereas Apple suffers from strong seasonality.
Samsung's latest smartphone offering, the Galaxy S4, goes on sale in the UK tomorrow. The device, which allows users to control the screen using their eyes. It is expected to give the company another boost, and is said to pose the greatest threat yet to Apple's iPhone.

- The South Korean company made a net profit of £4.2 billion
- Apple which sold 37.4 million iPhones in the March quarter, took 17.9 percent of the market
Samsung saw its profits leap by 41% in the first quarter of this year, thanks to a surge in sales of its smartphones.

Is it a game changer for Facebook? Almost certainly not. I suspect it will appeal to the die hard FB addicts but do consumers really want FB content to take over their whole phone?
What about all the other live feeds already available on your phone? What about all the other things you care about outside of FB connections?
Why would anyone want to put a FB soul into their phone? Will Apple or Samsung worry? Why would they? There isn't much here despite the fanfare.
Facebook has just released its advert for 'Home' on Android devices, saying it's a "whole new experience for your phone".
