What is Android?

Android is software for mobile phones, tablets and a growing range of devices encompassing everything from wearable computing to in-car entertainment. It launched in 2003 and is the world’s most popular mobile operating system (OS).
Android is an open source project (led by Google but it doesn't belong to them) called AOSP (Android Open Source Project). Google uses this project as a base to create its version of Android, which is then used by the other manufacturers.

Android Versions

As an OS, Android's job is to act as a translator between you and your gadget. When you take a photo, Android provides the button you tap and tells the phone what to do when you tap it. When you make or receive a call, Android tells your phone how to do that. When you play a game, Android tells the game what movements you’re making and what buttons you’re pressing. It’s like Windows, but for mobile devices.

The Android software itself is developed in conjunction with Google, who releases major updates to the platform every year. Manufacturers which run Android on their phones include Samsung, Huawei, Sony, Lenovo, HTC, LG and many others; it's currently operational on more than one billion devices.

What can an Android phone do?

Android phones are highly customisable and as such can be altered to suit your tastes and needs; with wallpapers, themes and launchers which completely change the look of your device's interface. You can download applications to do all sorts of things like check your Facebook and Twitter feeds, manage your bank account, order pizza and play games. You can plan events from your phone's calendar and see them on your computer or browse websites on your desktop Mac or PC and pick them up on your phone.

Another neat feature of Android is that it automatically backs up your contacts for you. When you set up an android phone you’ll need to create a Google Account or sign in with an existing one. Every time you save a number to the address book of your Android phone it will be synced to your Google Account.

The benefit of this is that if you lose your phone all of your numbers will be saved. The next time you get an Android phone (or an iPhone or Windows Phone if you prefer) and sign in with your Google Account, all of your contacts and friend's numbers will be displayed in your new phone’s address book immediately, no need to transfer or back them up anywhere else.

Syncing is a way for your phone to keep all your information; websites, contacts, calendar entries and apps up-to-date. This can happen over your phone's mobile data or WiFi connection, seamlessly, in the background.
