Samsung unveiled a new-generation Galaxy Note large-screen handset starting at USD 950 and said it will work closer with Microsoft so that services function better across its array of devices.
The Note 10 'phablet' which is set for release on August 23, comes in two sizes, with the larger beginning at USD 1,100.
The price puts the model at the premium end of a cooling global smartphone market.
The latest generation Note was introduced at a media event in New York by DJ Koh, head of IT and mobile communications, who touted it as "the world's most powerful mobile device."
"Every element of the Galaxy Note 10 was designed to help users achieve more," Koh said.
"Whether they're finishing a big project for work, capturing and editing a video, or playing their favorite mobile game, the Galaxy Note 10 will help them do it faster and better." Samsung's introduction of the first Note some eight years ago is credited with sparking a "phablet" trend of large-screen mobile devices that combine capabilities of smartphones with the screen size of tablet computers.
The unveiling of Note 10 and Note 10+ included an on-stage appearance by Microsoft chief executive Satya Nadella and an announcement by Samsung that it will be working more closely with the U.S maker of the Windows operating systems and related software.
Microsoft has long worked with companies behind Windows-powered computers or laptops.
"For years applications were built for single devices, but in a world of 5G, cloud and AI (artificial intelligence) we get to rethink it all," Nadella said.
