Samsung has sold more than 10 million units of its newest Galaxy S III model since its launch about two months ago.
"It appears that it has exceeded 10 million units," said J.K. Shin, head of the Samsung's mobile communications division, according to Yonhap news agency.
Shin said last month he expected the global sales of the new phone would surpass 10 million by the end of July, including sales of about a million units at home.
Galaxy S III offers face-recognition technology and improved voice-activated controls as well as a more powerful processor. It also has a 4.8-inch display, while it can detect eye movements and override the automatic shutdown if the user is looking at the screen.
The company said earlier this month it expected a record operating profit in the second quarter, boosted by strong sales of its flagship Galaxy smartphones.
