Samsung has started rolling out its over-the-air updates of Android 4.4.2 KitKat to Galaxy S4 and Galaxy Note 3 handsets in the UK. It will begin with unlocked phones first, which have updates available now.
The update, at 300-400MB in size, brings users right up to speed with the latest Android 4.4.2 KitKat meaning some subtle visual changes like the white notification bar icons.
Other extras Samsung owners can enjoy are immersive mode that allows an app to go full screen, a transparent notification bar, native cloud printing support and lock screen album art.
If you don't see the update as available right now keep checking as it's rolling out and may arrive on your device later in the day. If you're having trouble with the over-the-air update you could try using Samsung Kies software from your computer.
