Samsung has unveiled the largest smartphone so far – a 6.3in device called the Galaxy Mega.
The size of the phone fits into the ‘phablet’ category – a cross between a phone and a tablet.
It is only slightly smaller than some dedicated tablets on the market such as Amazon’s Kindle Fire and Google’s Nexus 7.
The South Korean firm says the new product has “split screen capability”, suggesting two apps could be run side by side.
Samsung’s faith in even larger phones comes despite debate over the appeal and pocket-stretching practicality of such devices.
However, Samsung claims the Galaxy Mega is “light and thin for incredible portability and easy, convenient mobile phone use”.
Sharif Sakr, senior European editor at Engadget said the phone was likely to be a success – but that its large footprint could be difficult to handle in some situations.
Mr Sakr said: “The absolute, final, logical maximum for how big a smartphone can be has already been exceeded so many times in the past two years that it’s impossible to dismiss.
“If the new phone is thin and lightweight … then its overall size shouldn’t be too impractical – except perhaps for those who often use their phone one-handed while walking or standing in a train carriage.
“The fact is there’s a good-sized population of users who are happy to sacrifice portability in order to watch video or run games and apps on a huge screen.”
Chinese company Huawei previously laid claim to the world’s biggest smartphone screen with its 6.1in Ascend Mate.
The Galaxy Mega – due out in May – will also be made with a slightly smaller 5.8in screen.
Both phones feature an eight megapixel camera, although the larger size has a faster 1.7Ghz dual core processor instead of 1.4Ghz.
Apple’s iPhone – the main rival to Samsung – features a 4in screen but a larger version is rumoured for the US company’s next iteration, expected this summer.
Between them, the two technology firms own 71.4% of the worldwide smartphone market, with LG a distant third.
