South Korea's Samsung Electronics, the world's biggest smartphone maker, says it expects to have sold 10 million of its newest Galaxy SIII model by the end of July, two months after its launch.
JK Shin, head of the mobile communications division, says robust sales of the model will help Samsung's mobile business post a second-quarter profit bigger than the first three months.
"We're getting more positive reviews for Galaxy SIII than the previous Galaxy S1 and SII since the release in Europe, the Middle East and South-East Asia beginning May 29," Mr Shin said at an event to mark the phone's domestic release on Monday.
He estimated that global sales of the new phone - currently available in 147 countries - will surpass 10 million next month, including about a million to be sold at home.
"We're doing fairly well in emerging-economy markets ... I think our second-quarter earnings will be better than the first quarter's, despite the difficult economic situation in Europe," Mr Shin said.
The company, the world's biggest technology firm by revenue, posted a record net profit for all its divisions of 5.05 trillion won ($A4.43 billion) in the first quarter, thanks largely to strong smartphone sales.
The third version of the Galaxy S series offers face-recognition technology and improved voice-activated controls as well as a more powerful processor that lets users watch video and write emails simultaneously.
It also has a 12.2cm screen that is 22 per cent larger than the SII, while it can detect eye movements and override the automatic shutdown if the user is looking at the screen.
Samsung shipped 44.5 million smartphones in the first quarter, exceeding the 35.1 million of US arch-rival Apple, according to market researcher Strategy Analytics in April.
Samsung, embroiled in patent lawsuits in 10 nations with Apple, is pinning its hopes on the SIII to further erode its rivals' market share before the expected new version of Apple's iPhone 5 this year.
In a rare victory for the Korean firm, a Dutch court last week ruled in favour of Samsung and ordered the US giant to pay unspecified damages for patent infringement.
