Samsung is still betting on the popularity of its so-called phablet devices, unveiling two new versions of its successful line of Galaxy Note products.

The company showed off this week the Samsung Galaxy Note 4 and the Galaxy Note Edge, both of which come with individual novel features, according to a report from The New York Times.

The Galaxy Note Edge comes with a second curved touch screen, which can be used for separate applications and to view notifications, while the Galaxy Note 4 can be linked to a virtual reality headset. That headset will be on sale at some point this year.

Both devices come with a 5.7-inch display, the same size as the Galaxy Note 3 but will have improved resolution and quality. The cameras on both Notes have been improved with a 16-megapixel rear-facing camera and 3.7 megapixel front-facing camera.

Samsung claims that the improved cameras have features like image stabilization and a better panoramic mode, allowing users to take better photos.

The Galaxy Notes will also have better software than previous versions, making use of the device more similar to a PC than a tablet. It's updates like this that have made the Samsung phablets -- combo of phone and tablet -- more often used than either a phone or a tablet separately.

Samsung Senior Vice President Shoneel Kolhatkar told PC Mag that phablet users spend about 390 minutes per day on such devices versus 229 minutes per day for smaller phones.

Both devices have a quad HD, 518 ppi 2,560-by-1,440 Super AMOLED display -- the same quality as the Galaxy S5 but much denser. They are powered by a 2.7GHz Qualcomm Snapdragon 805 processor and run Android 4.4.4 with all of Samsung's usual extensions.

Samsung will be hoping that the new Galaxy Note devices maintain the popularity of its last phablet release, the Galaxy Note 3, which sold 5 million units in its first month of release.
