The Samsung Galaxy Note 4(hand-on)

 Galaxy Note 4  comes with new and improved specs in both hardware and software, but the design of the 5.7-inch phone itself has made a huge step in the right direction: It comes with an aluminum frame, and based on my first impression, it's the best looking of the bunch. It's time to explore Samsung's latest large-screened device.

            I shouldn't sing so much praise over just one aspect of the phone's design. After all, it's entirely possible to make a phone with metal sides look ugly and/or cheap, right? Fortunately, Samsung kept that in mind, because in my first impressions, it's hard to find fault with any aspect of the Note 4's hardware. The sides use chamfered edges to meet the front and back.the removable back is still made of the same "leather-like" polycarbonate build as the last Note, but Samsung got rid of the distracting stitches that went around the perimeter of the phone. The glass is 2.5D, which means it's not entirely flat -- like many Nokia Lumias (and even the Galaxy S3), there's a very subtle bend along the edges of the screen.

Compared to the previous model, the Note 4 uses the same screen size and is about as thin (8.3mm), but it's 2.3mm taller, 0.6mm wider and eight grams heavier.

This New Galaxy Note comes with plenty of improvements over the last. The Super AMOLED screen got a bump from 1080p resolution to Quad HD (2,560 x 1,440); the rear-facing camera is now 16MP (up from 13); and the battery gets a marginal increase from 3,200mAh to 3,220mAh. The Note 4 also marks the first time in a long time that Samsung has improved the front-facing camera: It's blessed with a 3.7MP sensor and an aperture of f/1.9 for theoretically better low-light selfies. The Korean Note 4 will feature an octa-core Exynos 5433 chipset, which is split up into a 1.9GHz quad-core processor for bigger activities and a 1.3GHz quad-core for the menial tasks; everywhere else, the Note 4 will boast a 2.7GHz quad-core Snapdragon 805 with a 600MHz Adreno 420 GPU. Both versions will feature 3GB of RAM, the same amount as the Note 3. For internal memory, you can choose between 32 and 64GB, and you can add up to a 64GB microSD card (not 128GB, oddly). Lastly, just like the Galaxy S5, you'll get a fingerprint scanner on the front and a heart rate monitor on the back underneath the camera and next to the flash; Samsung's added a UV light sensor to the back as well.

If you recall, the Note 3 came with an unsightly USB 3.0 connector port, which Samsung added for the sake of faster data speeds. This year, the phone maker went back to USB 2.0; the product managers said that not many people were using the 3.0 port for data transfers, so they didn't see the point in taking up room inside the phone for that purpose. The charger at least comes with fast-charging capability and the phone maker claims that the battery will charge 30 percent faster when you use the charger that comes in the box. I clarified with Samsung that it chose a proprietary solution instead of licensing Qualcomm's QuickCharge tech, but it insisted that you could still use QuickCharge 2.0-compatible chargers to achieve the same results.(wow)

 If , We come to Front-Facing Camera.Front-facing camera is supposed to be better in low-light scenarios, thanks to its f/1.9 aperture, and Samsung has added a "Smart Optical Image Stabilization" feature to the rear camera to minimize shaking and allow more light in dark situations. It feels as though there's more of a focus on the front cam, however, since so much attention is being put on the selfie experience; on the Note 4, it comes with a 90-degree shooting angle by default that can be extended to 120 degrees through a special "wide selfie" mode that takes three photos and stitches them together -- just like a panorama shot. The Note also comes equipped with three mics to help with directional noise cancellation.

The Note 4 uses Android 4.4 KitKat and keeps to the same overall UI as the Galaxy S5. But since this is a Note product, there are plenty of enhancements to the S Pen experience, both in hardware and software. First, Samsung has doubled the pen's pressure sensitivity.

As for software improvements, there are a few features worth pointing out. Snap Note is the most impressive: You can take a picture of any analog note (a regular notepad, signs, pieces of paper) and within a couple minutes, the Note 4 can convert it into digital, which means you can erase and edit that information to your heart's content. There's also a new Smart Select mode, which lets you select multiple images in a gallery with your pen, or multiple lines of text without having to long-press the screen and highlight it manually. Samsung's added a new way to float apps and web pages by dragging your finger toward the center of the screen from the top-right corner; you can then resize the app, as well as minimize or maximize it.

Samsung says the Note 4 will be available starting in October and will come in four color options: white, black, gold and pink. Some of the colors, like black and gold, feature different color accents on the metal sides
