Samsung unveiled two new high-end smartphones, with the latest version of its Note phablet line joined by a large-screen version of its Galaxy S6 Edge, as it looks to get a head-start on Apple’s next-generation iPhone.

The devices share a number of core features, including processor, memory, and camera options. Both also have 5.7-inch quad-HD (2560×1440 pixel) screens, although in the case of S6 Edge+ this comes with the wrap-around display debuted with the Galaxy S6.

The company is billing Galaxy S6 Edge+ as being “best for multimedia experience”. The curved screen offers an “apps edge”, which provides shortcuts to favourite apps, and “people edge”, to give easy access to contacts.

Galaxy Note 5, in contrast, is described as “perfect for multitaskers”, and supports a “much refined 5th generation S-Pen” stylus. It is also said to be “inspired by the design legacy of the Galaxy S6,” with a narrow bezel and curved back.

Both devices feature improved video capabilities, including digital image stabilisation on both the front and rear cameras, and support 4K video capture. Also on the roster is a “live broadcast” feature which lets users stream full-HD video from the device to individuals, groups of contacts, or even via YouTube.

Other common specifications include 64-bit octacore (2.1GHz quad and 1.5GHz quad) processors, 4GB of RAM, 16MP rear and 5MP front cameras.

The pair also feature embedded wireless charging technology, which is “compatible with virtually any wireless pad available today”.

Samsung is set to segment markets as to whether they get Galaxy S6 Edge+ or Galaxy Note 5. Daniel Gleeson, senior analyst for research firm IHS, suggested that while this may be to enable the company to focus its marketing efforts, it would also mean that customers could lose out due to the different features of the two (such as the stylus).

“A more likely possibility is that the accelerated timetable and earlier announcement has prevented Samsung from having the required levels of stock for a simultaneous global launch for both handset models. If this is true, then it negates part of the benefit of announcing early,” he said.

Samsung said the devices will reach the market imminently, with 32GB or 64GB storage options, in white, black, gold and silver.
