NEW YORK—Samsung unveiled two new smartphones Thursday to ramp up its efforts to win over consumers seeking large-screen handsets, and announced launch dates for its mobile payment service.
The moves are aimed at keeping the South Korean giant atop the global smartphone market and countering U.S. rival Apple, which has made gains with its large-screen iPhone 6 and 6-Plus and its tap-to-pay feature.
At a New York media event, Samsung unveiled its Galaxy S6 edge+, the latest update for its flagship device, and Galaxy Note5, its main device in the "phablet" market.
"Today the journey continues in the large-screen category that Samsung created," said J.K. Shin, Samsung's head of IT and mobile communications.
The S6 edge+ and Note5 each have a 5.7-inch display, but the S6 has smaller overall dimensions and a curved "dual edge" screen that sets aside a portion of the display for contacts or other content.
The company also announced that its Samsung Pay service would roll out in South Korea on August 20 and in the United States on September 28, and that it would launch in Britain, Spain and China with partners to be named in each market.
Shin said he expects wide adoption because Samsung Pay "doesn't cause small business to upgrade their terminals and will be accepted almost everywhere on day one."
Samsung said its mobile service can be used with magnetic stripe terminals as well as those using updated NFC or "near field communication" contactless payments employed by Apple Pay.
InJong Rhee, Samsung Electronics vice president, said that "NFC is fine technology but most stores don't have it."
He added that Samsung Pay will be secured by its Knox software, which creates a one-time code without transmitting credit card numbers.
Samsung has remained atop the global smartphone market even though its sales have been slipping in the past year
With the new devices, Samsung expands from its 5.1 inch display on the existing Galaxy S6, and leapfrogs Apple's handsets at 4.7 and 5.5 inches.
The new handsets, which have Samsung Pay and wireless charging options integrated, will go on sale in the U.S. and Canada on August 21, Samsung said.
The Note5 is the upgraded version of the phablet, which Samsung is generally credited with popularizing. The new device has a new pop-out pen stylus and shares its upgraded 16-megapixel camera with the S6 edge+.
Kantar Worldpanel analyst Carolina Milanesi said Samsung trailed Apple in the phablet market—devices with screens at 5.5 inches and above—in the second quarter.
Avi Greengart at the research firm Current Analysis said on Twitter that "Note5 is a worthy upgrade, but unlikely to expand the category" and that the S6 edge+ "is pretty but hard to hold."
Daniel Gleeson at IHS Technology said the Note5 appears aimed at professionals and business users due to its stylus and keyboard attachment, while the S6 edge+ "is a much more fashion-forward device and is likely to appeal to a younger, hipper market."
According to IDC, Samsung led the smartphone market in the second quarter with a 21.7 percent market share, even though sales dipped from a year earlier and its market share was below 24.8% in the same period a year ago.
Apple, which briefly took the lead in the fourth quarter of 2014 with its new iPhones, saw its market share rise more than two points from a year earlier to 14.1%, IDC said.
Gleeson said Samsung Pay faces challenges because of the head start by Apple and Google's Android Pay.
"Unlike Apple, which has accumulated 800 million payment card accounts associated with iTunes, Samsung lacks this critical element for its payment service to quickly gain traction," he said in a note to clients.
"Samsung Pay's co-existence with Android Pay is likely to create frictions in the Android ecosystem as consumers could be confused by the two payment options.
