NEW YORK: Sounding the bugle for its annual warfare with Apple right on its home turf, Samsung on Thursday launched its flagship Galaxy Note 9 -- a device with a mammoth 1 TB memory, bigger battery and a Bluetooth-equipped S Pen.

The 6.4-inch Note 9 comes in four colours and two variants -- 6GB RAM and 128GB in-built internal memory (expandable up to 512GB) and 8GB RAM with 512GB ROM that can be expandable up to 1TB with an additional 512GB microSD card -- a delight for the gamers and heavy-duty users.

"The Note has always been our showcase for premium technology and industry defining innovations. It is designed for a level of performance power and intelligence that today's power users need," DJ Koh, President and CEO of IT & Mobile Samsung Electronics, said at the jam-packed Brooklyn's Barclays Center in New York City.

Both variants of the phablet will arrive in India by the end of this month and the price and exact availability date will be announced on August 10. However, not all the four colour models may initially make their way to India.

"The pricing will play a bigger role in deciding whether Samsung wants to fight the Chinese players or continue its focus on the premium customers in India," Satish Meena, Senior Forecast Analyst at Forrester Research, told IANS over phone.

The device that runs OS Android 8.1 (Oreo) will have the latest Qualcomm Snapdragon 845 system-on-chip (SoC) for the US customers and the models powered by Samsung's very own "Exynos 9 Series 9810" chips will head to the rest of the world, including India.

The device will sport dual camera system (12MP+12MP) with dual optical image stabilisation (OIS) at the rear -- with 2 times more powerful optical zoom and up to 10 times powerful digital zoom -- and an 8MP front shooter.

Note 9 with Quad HD+ Super AMOLED display houses 4000mAh battery -- 21 per cent bigger that Note 8 - that is paired with fast-charging technology compatible with both wired and wireless charging.

When it comes to Stylus Pen (the company calls it S Pen), there is much more to experience this time.

"S Pen now has remote control functionality along with Bluetooth connectivity and extremely fast charging," the company executive explained.

"S Pen can control anything, from YouTube or photo gallery to operating the phone camera. It can guide entire presentations at office meetings. We have opened software development kit (SDK) for S Pen and will soon have more applications and features," they added.

The fingerprint scanner is comfortably located just below the rear camera system.

Note 9 also comes with dust and waterproof IP68 rating (including S Pen) and houses "Samsung Knox" enterprise mobile security solution pre-installed for enhanced security.

The flagship smartphone has also retained the iconic 3.5-mm headphone jack.
