The Samsung Galaxy Note 3 has just been made official, bringing with it most of the features rumoured throughout the past few months, which makes this a pretty impressive launch from Samsung just ahead of an expected Apple upgrade to the iPhone 5S.What that means in practical terms is a smartphone packing a 5.7-inch super AMOLED screen with Full HD 1920 x 1080 pixel resolution, along with a 2.3GHz quad-core Qualcomm Snapdragon 800 processor (for the 4G model) or a 1.9GHz octa-core Samsung processor in 3G-land. We'll probably see the former here, as the phone is compatible with all 4G networks in the UK.Also present is Android 4.3 Jelly Bean, a 13-megapixel camera with auto focus, Samsung's Smart Stabilisation technology and an LED flash, along with a front-facing 2-megapixel camera on the front, also with Smart Stabilisation.Feature-wise, there's a lot of things Samsung has been talking up of late, including Dual Shot, Dual Recording and Dual Video Call, while the rumoured 4K video recording also made the cut, able to shoot UHD content in 30fps for playback on the right display. Alternatively, there are options for Full HD or slow motion video shooting.The famous S Pen has also been enhanced, with new features when you click a button on the stylus, opening up Action Memo, Scrapbook, Screen Write, S Finder and Pen Window.For example, Action Memo opens up phone functions, including calling, searching your address book or the web. Scrapbook is a place to keep content for later, Screen Write allows you to write over a screenshot (and no doubt send the quirky note to friends), S Finder is a search tool for your note and Pen Window creates a new multitasking window wherever you draw it. Clever.The whole thing is a touch smaller and lighter than the previous Note, with the new device offered as a 32GB or 64GB model and in Jet Black, Classic White or Blush Pink for the colours. 25 September is said to be the launch date, pricing still to be confirmed for the UK.
