Samsung did focus on quality of Note 4 rather than its size as compare to Note 3. Samsung improved its software cleverly for better user experience. The elegance of Note 4 is much better than Note 3. It gives premium look and feel when you will carry this Note 4 in your hand. The function of S Pen has become more functional, logical and looks like a part of package.  

Samsung Galaxy Note 4 Review

The screen now boasts Quad HD Super AMOLED (2,560 x 1,440 resolution) technology that stretches to 500 pixels per inch. Couple this with what Samsung is calling an adaptive display – one that changes depending on the light of the place you are viewing the screen – and on paper you have the optimum viewing no matter what situation you are in. There is a lot of similarity between the Note 3 and its successor. Size difference between the two chassis is definitely negligible – the Note 4 comes it at 153.5 x 78.6 x 8.5mm, compared to the Note 3’s 151.2 x 79.2 x 8.3mm size. it’s obvious that  Samsung hasn’t re-invented the Note range but refined it with clever software updates and slight tweaks here and there. Samsung has definitely observed about its latest line-up feeling plastic-y in the hand and has decided to give the Note 4 more of a premium finish, with a metal rim surrounding the handset, shielding the rest of the chassis like a velvet rope protecting celebs from real people in a club. I love the way the Galaxy Note 4 feels in the hand and being a regular user of the Note 3, it definitely felt different enough and it’s light too, just a touch over the weight of the Note 3 at 176g. The most notable is the heart rate monitor on the back which also has a neat camera functionality and the back has been improved somewhat too, but is still a little too artificial leather for my liking.

Galaxy Note 4 S pen

The Samsung S pen has been improved and gives the real feel of writing on a paper in natural handwriting flow and rhythm. User can also use S Pen just like mouse. Click he button on the side of the S Pen and you are in Smart select mode. Where you can highlight whole passages of text from a website, or even clip out sections of a site and put it into your own clippings archive. Snap mode has also been improved on the Note 4. While you used to just be able to snap two separate services to the top and the bottom of the screen, you can now “resize” an app much like you would a widget. Key features
