The all-new Samsung Galaxy Note 4 has now been officially unveiled, but what does the successor to the Samsung Galaxy Note 3 actually bring?

Well there's no change to the size of the screen, which still comes in at the whopping 5.7 inches that we have come to know and love, but Samsung has made some significant changes to that killer feature.

That 5.7-incher is now a Quad HD Super AMOLED (2,560 x 1,440 resolution) technology that stretches to 500 pixels per inch.

Samsung Galaxy Note 4 release date and price

The Galaxy note was announced at IFA 2014 on September 3. Samsung had sent invites for an event advising people to 'Note the date', which was a bit of a give away, and so it proved.

Earlier in the year Samsung mobile chief Lee Young Hee told Bloomberg that it would be launched in the second half of 2014, while the Korea Times claimed it had been told the Note 4 will arrive at the IFA show in Berlin. Android Geek's sources got even more specific, claiming it will arrive on September 3, as did The Korea Times.
There's been very little said about the price yet, but a listing on Indonesian site erafone puts it at IDR 9,499,000 (or roughly £490 / $810 / AU$870) which seems believable, especially since those conversions don't include local taxes. Better start saving.

Samsung Galaxy Note 4 screen
First up, screen size. The original Note rocked 5.3 inches, the Note 2 showed up with a 5.5-inch display and the Note 3 pushed things to 5.7 inches.

Going by this logic the Galaxy Note 4 should have come with a 5.9-inch display, which would see it match the HTC One Max and LG G Pro 2, while still falling short of the 6.4-inch Sony Xperia Z Ultra.

But actually Samsung showed admirable restraint, keeping the Note 4 to the 5.7 inches of its predecessor, but throwing a boat-load more quality into its killer feature.

The screen now boasts Quad HD Super AMOLED (2,560 x 1,440 resolution) technology that stretches to 500 pixels per inch.
Plus, Samsung is throwing in what it 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.

Samsung Galaxy Note 4 power and storage
We're still digging into the Samsung Galaxy Note 4 - but while we update this article here's what was rumoured to be the specs of the Note 4.

The Galaxy Note 4 bring with it a pretty impressive 2.7GHz quad-core Qualcomm Snapdragon 805 processor, which certainly won't be struggling to keep things moving despite the screen.

Also worthy of, ahem, note, is the 3GB RAM that the phone is packing - there are still plenty of people with PCs that don't rock that kind of memory.
The internal memory of the Galaxy Note 4 is a not insignificant 64GB, which should mean you don't have to choose between your collection of Jean Claude van Damme movies and your lovingly put together eclectic music.

Samsung Galaxy Note 4 camera
The Galaxy Note 4 came in for quite the camera upgrade, but not the 20MP sensor that a report from ET News suggested was due for release in the second half of the year.


Instead, it's gone from 13MP to 16MP but camera-philes will be more impressed with the f stop, which now clocks in at f1.9. That lets in 60% more light and makes for better quality images.
You can also use the camera in unison with the S Pen. A new feature called Snap Note allows you to take a picture of a piece of paper (or whiteboard) and change what's in the picture.

Samsung Galaxy Note 4 operating system
The Samsung Galaxy Note 4 runs the latest version of Android, Android KitKat.
It is of course overlaid with Samsung's TouchWiz interface just like the new version which adorns the Galaxy S5.

Samsung Galaxy Note 4 chassis

Samsung 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.
Our first impressions suggested that the Note 4 felt great in the hand although that faux leather back is going to be as divisive as it was in the Galaxy Note 3 despite some design tweaks and the inclusion of a heartrate monitor.
