Samsung has promised to have the phone out by the end of April. Exact launch dates will depend on the country, but we expect the UK to be one of the first on the list. We'll bring you updated information as and when it becomes available.
The good news is that you won't be short of choice when it comes to buying the Samsung Galaxy S4. Two of the major UK networks have confirmed that they will be carrying the new phone - no great surprise, when you consider the huge success of the Galaxy S3 and the amount of hype that has been building up to the launch of the S4.
As you'd hope considering the Galaxy S4's LTE capability, it will be available on the UK's only 4G network - EE - and Three has also thrown its hat into the ring.
Vodafone and O2 have yet to say either way, but we find it hard to believe that they will pass up the chance to stock this year's potential biggest seller.
Pricing hasn't yet been announced, but we can take a fair stab at expected prices. We'd imagine that launch prices will be the same as for the S3 when it launched back in May - a wallet-busting £499. Once again though the tough competition from Google's own Nexus 4 device may force Samsung to lower its price in order to compete - unless of course the hardware specification is a big step forward.
Samsung's latest handset could mean the end of having to scroll through webpages - as the phone can 'watch' users to see where they are looking.
The handset, to be unveiled in New York on 14th March, is also believed to have a five-inch screen and a 13 megapixel camera as Samsung bids to jump ahead of Apple's iPhone 5.
It is believed the 'eye tracking' system will allow users to automatically scroll through a news story, for example, as the handset knows when they have reached the bottom of the page.
'The phone will track a user’s eyes to determine where to scroll', a Samsung employee told the New York Times.
In January Samsung filed for a trademark in Europe for the name 'Eye Scroll', which is believed to refer to the new feature.
It also filed for the 'Samsung Eye Scroll' trademark in the United States in February, describing the service as 'Computer application software having a feature of sensing eye movements and scrolling displays of mobile devices, namely, mobile phones, smartphones and tablet computers according to eye movements; digital cameras; mobile telephones; smartphones; tablet computers.'
The rumours come amid increasing speculation over the handset ahead of its unveiling on March 14th in New York.
Samsung Electronics' mobile division chief JK Shin told South Korea's Edaily news website that the decision to launch the new smartphone in the U.S. was spurred by demand from mobile networks.
'We introduced the Galaxy S III in London last year, and this time we changed the venue (to New York)... as we were bombarded with requests from U.S. mobile carriers to unveil the Galaxy S IV in the country,' he said.
Samsung unveiled its first Galaxy S during the CTIA mobile trade show in the U.S. in 2010, followed by the Galaxy SII at the MWC fair in Spain in 2011 and the Galaxy SIII in London last year.
