Been eyeing up Samsung's Galaxy Gear but don't want to spend the cash getting a Galaxy Note 3? Well now you don't have to. Android 4.3 Jelly Bean has now landed on the Galaxy S4 which means the smartphone will now work with Samsung's smartwatch. Unfortunately you'll have to have an unlocked GS4 to take advantage of this, but over-the-air updates should be coming to carrier-locked versions soon.
Also included in the update is Samsung's own reading app, wallet app, and various software updates to imaging, the browser and keyboard.
