The South Korean tech giant said it will host an "Unpacked" gathering on August 9, at New York's Barclays Centre.
The date is some two weeks earlier compared with the predecessor Galaxy Note 8, which was unveiled on August 23, 2017.
Industry watchers said Samsung decided to showcase the new flagship smartphone earlier than expected to compete with Apple, which is also set to launch a new iPhone later this year, Yonhap news agency reported.
While the tech giant used the slogan "Do bigger things" for the Galaxy Note 8, the latest teaser poster and video only came with the schedule.
The presumed Galaxy Note 9 is expected to come with a 6.4-inch screen, which is slightly bigger than its predecessor's 6.3-inch display.
Other watchers have also claimed that the new phablet may come with an ample battery capacity of 4,000 mAh, compared with the Galaxy Note 8's smaller 3,300 mAh.
