Another key addition to Jelly Bean is the company's new Google Now service. Google Now appears the moment you open the Nexus from sleep mode and can also be accessed by pulling up from the device's home button.
The feature houses a number of dynamic "cards", each containing information the device thinks is relevant to the user. This is based on information taken from users' Google accounts. Google Now offers Weather, Traffic, Transit, Places, Flight, Sports, Currency and Translation cards.
Each card updates automatically when connected to a WiFi network. We particularly liked the Sports and Transit cards, with the Sports card offering up to date scores and news on our favourite sports teams, while the Transit card told us which bus or train was scheduled to arrive next whenever we were near a bus stop or rail station.
It's worth noting that the permissions required to use Google Now do require you to grant the internet search giant access to a lot of your personal data and we really recommend that you read the terms and conditions before clicking yes. Also, the Nexus 7 - the only device already running Jelly Bean - doesn't have 3G connectivity, meaning that you can't use Google Now on the go at present.
As well as its new recommendation features and Google Now service, Jelly Bean also features a number of new apps. Three of our favourites are the Chrome, Google Currents and People apps.
The Chrome web browser beta was available on Android 4.0 Ice Cream Sandwich alongside the OS core Browser. With Jelly Bean, Google has released the full Chrome web browser. For us this is a great positive, with Chrome in our mind being the best mobile web browser on the market, offering speedy, multiple tab browsing.
