The world's largest smartphone maker by market share has put safety at the centre of a phone-cum-tablet that is likely to compete for pre-holiday season sales with a widely expected 10th anniversary iPhone from US rival Apple Inc.
The unveiling comes five months after the release of the Galaxy S8 smartphone. Analysts said brisk sales of that device indicate recovery in Samsung's standing, after battery fires prompted the October withdrawal of the Galaxy Note 7 just two months into sales at an opportunity cost of $5.48 billion.
Cumulative sales of the S8 and S8+, released in the period, were 15 percent over those of the S7, Samsung said in July.
The South Korean firm has been a principle driver of growth in handsets with 6 inch-plus screens, a category which Strategy Analytics expects to grow 10 times faster than the overall market next year.
Other features include security technology, such as facial recognition and fingerprint and iris scanning, and artificial intelligence in the form of Samsung's Bixby voice-command assistant.
The Note 8 will be sold from mid-September, Samsung said, without elaborating on place or price.
