Samsung has announced the Samsung Galaxy Note 4 at the Unpacked 2014 Episode 2 event at IFA 2014 in Berlin.

The Samsung Galaxy Note 4 follows the design style of the Note 3, but it retains the soft-touch faux leather back. There's a metal frame.

On the display, the 2.5D display is now stronger, designed to make it harder to break. There's now a 5.7-inch QHD Super AMOLED display, with 2560 x 1440 pixels, 515ppi.

There has been a range of UI updates evolving the TouchWiz experience of the SGS5 over Android 4.4 KitKat. You'll be able to access the multi-tasking functions through the recent apps key, so things are easier to find than before.

The S Pen has been updated, now with 2048 pressure points. It's designed to replicate the experience of an "analogue" pen, offering double the sensitivity of the Note 3. You can now write with a calligraphy pen or fountain pen as new fun options.

A new feature called smart select will let you select a collect of items and share them all in one go. There's an additional button to help you select text, making it easier to copy and paste.

The Samsung Galaxy Note 4 will come with cat 6 LTE, so it will be super fast. The internals should be fast too, with a 2.7GHz Qualcomm Snapdragon 805 chipset and 3GB of RAM. You'll get 32GB of internal storage with the option to expand via microSD.

On the rear is a 16-megapixel camera and on the front is a 3.7-megapixel camera. The rear camera has optical image stabilisation, so you should get great images. 

The front camera has been designed to capture 60 per cent more light, designed to improve those low-light selfies.

The Samsung Galaxy Note 4 will come in black, white, gold and pink. There's no word on pricing or availabilty as yet, but we'll update as soon as we know.
