Samsung didn't increase the screen size of the Galaxy Note 4, the overall size of it is actually same as its predecessor. The screen has an upgraded Quad HD (2,560 x 1,440) resolution with Super AMOLED display, which reproduces clearer and more vivid images with deep contrast and better viewing angles.
The display actually has improved a lot, and the scrolling experience is good thanks to the 2.5D curved glass.
Looking at the design, yes, it's finally a metal frame. Samsung has introduced the first metal frame device, Galaxy Alpha before, and now the same thing happens on the Galaxy Note 4. The back is plastic though, just like the Galaxy S5. It also comes with heart rate sensor below the camera lens and there's a fingerprint sensor lies under the home button. It feels good when hold in hands as the size is not too big due to its slim bezels.
Besides that, Samsung has partnership with a few casing companies to launch the accessories for the Galaxy Note 4. There's a blinky casing for those blink lovers, no word on the pricing of the accessories, but don't expect it will cost you less than RM 100.
The Galaxy Note 4 is really a nice phablet from the company. Its S-Pen functionalities bring you a true writing experience, however, we don't have much time trying out the S-Pen. The phablet is now available in Malaysia for RM 2,499 and Maxis, DiGi, Celcom and U Mobile are offering the phablet with plans.
