What is Android and what is an Android phone?

Android is now a decade old and the most popular mobile operating system in the world. You'll find it on mobile phones, tablets and even on TVs and in cars. So what actually is Android? Here's all you need to know about Google's mobile OS.

Here we'll help you to understand what Android is, what it can actually do, what are the best Android devices you can get, how do you use Android apps and plenty more besides.

What is Android?

Android is a mobile operating system which is found on a variety of modern devices, the most popular being smartphones. On top of that, you'll also find Android on tablets, TV streaming boxes and other portable gadgets.

Android is basically a piece of software which allows your hardware to function. The Android OS gives you access to apps, including many of Google's own creation. These allow you to look for information on the web, play music and videos, check your location on a map, take photos using your device's camera and plenty more besides.

Without Android, none of this would be possible.

Android phones are highly customisable, so they can be altered to suit your personal tastes and needs. For instance, you can set your own wallpaper, themes and launchers, which completely change the look of your device's interface. You can download new applications to do all sorts of things like check your Facebook and Twitter feeds, manage your bank account, order pizza and play games.

How to get started with Android

Check out our guide on how to set up an Android phone, for an idea of what you’ll need to do to get started. One of your first tasks will be to create a Google Account (or sign in with an existing one). This gives you email functionality and also provides a great way to backup your contacts, save your files online and so on.

The benefit of this is that if you lose your phone, all of your numbers and important data will be saved. The next time you get an Android phone (or other device) and sign in with your Google Account, all of your contacts and numbers will be displayed in your new phone’s address book immediately. No need to transfer them over or back them up anywhere else.

In fact, you can sync your personal info across all kinds of Android devices. This includes favourite websites, calendar entries and purchased apps. This is all backed up seamlessly, in the background.

What apps can I get on an Android phone?

There are millions of apps and games available to download from the Google Play store (formerly Android Market). There are camera apps that allow you to take pictures with artistic effects and music players which allow you to stream songs from the web or create playlists. You can customise the appearance of your Android handset with a number of wallpapers based on pictures you’ve taken yourself or downloaded from the internet too.

There are also various on-screen widgets to download which allow access to, and the alteration of, settings on your phone, without the need to dive through menus as you would on non-Android devices. You can pretty much create your own system of shortcuts and menus to better suit how you uniquely use your phone.

You can also download a huge range of games for your Android phone to keep you entertained on the go. Here are our favourite Android games of all time.

How can I download apps onto an Android phone?

The majority of apps can be downloaded from the Google Play store (the equivalent of Apple’s App Store), which includes a mix of free as well as 'premium' apps that you have to pay for. Some apps have ‘lite’ versions which are free, in the hopes you’ll enjoy them enough to upgrade to the full premium version. Others - like Pokémon GO - are free but include adverts or the ability to make in-app purchases.

The same account that lets you backup your contacts can also have financial details added to it, giving you the ability to purchase content from the Google Play store directly. You can pay either by debit or credit card and initial setup takes less than five minutes from a computer.

Although there are well over a million apps available to Android users in the Google Play Store, some developers choose to make their apps available to download from their own sites or alternative app stores. In order to download them, you have to change some settings on your phone before visiting these sites on your Android device's web browser. By downloading apps outside of the Google Play Store, you do run the risk of attack in the form of data theft or by leaving yourself more susceptible to viruses, so be careful if you choose this route.

Should you upgrade or change your Android phone; log into your Google account and you’ll be able to download your previously owned apps again, without being charged. In recent years, Google has expanded Google Play to offer more than just apps, with books, magazines, music and movies available for purchase and download in much the same way too.

Who actually makes Android phones?

Any handset maker is free to make an Android phone if they want to. The likes of Motorola, HTC, Samsung and Sony, Acer, Alcatel, Asus, Huawei, LG and ZTE have all made Android phones (and tablets). Blackberry has put out several Android phones since 2015, including the Priv and the KEYOne. And Nokia is enjoying a resurgence in 2017, thanks in large part to its new Nokia 3, 5 and 6 phones which run Android OS.

Does Google make any Android phones?

Although Google owns the OS (Android), the company has not made any of the smartphones on which it runs in-house (it did make the Android-powered Pixel C tablet in 2015). However, it has partnered with various handset manufacturers over the years to make its own-brand smartphones under the 'Nexus' name.

Google's Nexus phones were typically the first to receive new updates and were considered to be the flagship Android phones, even though some other Android devices sported larger screens, better cameras and more powerful hardware.

In 2016, Google shelved the Nexus brand name and replaced by launching two new phones called the Pixel and Pixel XL. For all intents and purposes, these new phones enjoy all the same benefits as the Nexus devices did and are essentially the spiritual successors to the Nexus line.

You can expect to see some new Pixel 2 phones in 2017.

Android updates

Google is constantly working on new versions of the Android software. These releases are infrequent; at the moment Google is releasing a big Android update once a year. Check out our handy, comprehensive guide to every Android version out there.

Versions usually come with a numerical code and a name that’s so far been themed after sweets and desserts, running in alphabetical order.

  • Android 1.5 Cupcake
  • Android 1.6 Donut
  • Android 2.1 Eclair
  • Android 2.2 Froyo
  • Android 2.3 Gingerbread
  • Android 3.2 Honeycomb - The first OS design specifically for tablets, launching on the Motorola Xoom
  • Android 4.0 Ice Cream Sandwich: The first OS to run on smartphones and tablets, ending the 2.X naming convention.
  • Android 4.1 Jelly Bean: Launched on the Google Nexus 7 tablet by Asus
  • Android 4.2 Jelly Bean: Arrived on the LG Nexus 4
  • Android 4.3 Jelly Bean
  • Android 4.4 KitKat: Launched on the LG Nexus 5
  • Android 5.0 Lollipop: Launched on the Motorola Nexus 6 and HTC Nexus 9
  • Android 6.0 Marshmallow: Launched on the LG Nexus 5X and Huawei Nexus 6P
  • Android 7.0 Nougat
  • Android 7.1 Nougat: Launched on the HTC-made Google Pixel and Pixel XL
  • Android 8.0 Oreo: Rumoured to be launching on the Google Pixel 2 and Pixel XL 2

The latest public version, Android Nougat, makes the OS even faster than ever with a feature called 'instant apps'. It also offers improved battery life with Doze on-the-go and adds native VR support. Here's what's changed between the different Android versions.

Android version

When does Google announce new versions of Android?

As previously mentioned, Google tends to put out a fresh new version of Android once a year (although minor updates roll out constantly).

When it comes to Android, Google often releases a beta version in the first half of the year. This often coincides with Google I/O, a big developer event held annually around May. At Google I/O we usually find out more about the new Android update, including the best features and any UI improvements.

Check out our guide to the next Google/Android launch event for more info.

Android tablets

Like Android phones, Android tablets come in all shapes and sizes. These can range from the 7-inch screen of the Asus-made Google Nexus 7 to far larger displays, such as the 10-inch display found on the Nexus 10.

Somewhat confusingly, some older Android tablets; like the original Samsung Galaxy Tab, launched running Android 2.2 Froyo - a version of Android designed for phones, whilst Android 3.0 Honeycomb was the first release of the OS specifically for tablets.

Older Android tablets which didn’t run on 3.0 Honeycomb couldn’t benefit from things like the redesigned YouTube app, improved widgets and certain tablet-specific apps like SwiftKey for Tablets.

This fragmentation between Android phones and tablets was eliminated with the launch of Android 4.0 Ice Cream Sandwich, which was designed to operate on either type of device and scale accordingly. Android Jelly Bean introduced a number of improvements for both the smartphone and tablet experience over the likes of ICS (Ice Cream Sandwich) and that trend continues with the latest release, Android 7.0 Nougat, which brings features like split screen support to the table.

Do Android updates cost anything?

Android updates are free to download and install. Updates bring a number of new features and changes to Android each time. Generally, with each update, the speed and overall performance of Android is improved upon.

Most of the high-end Android phones are scheduled to receive updates first. Most Android phones will have at least one update during their life cycle, with some having two. A life cycle is usually around 18 months, but depending on the phone this can be longer. These updates differ from app updates, which are smaller, incremental releases for individual applications installed on your Android device.

How do I update my Android device to add new features?

Android updates are normally received OTA (Over The Air), that is, sent directly to your Android phone without the need for a computer. Normally, once your Android phone or tablet is due to get an update, you'll see a notification in the bar at the top of the screen. You'll then be prompted to connect to WiFi to avoid incurring extra data charges - updates can be quite big and downloading them over a mobile data connection isn’t advised as it may result in expensive data charges.

Updates are generally one-stage processes and relatively straightforward, but in some cases, you may need to backup/save any media (photos, movies, music) or apps you've downloaded before updating.

When beta versions of Android are announced, you can download them early to any recent Google-branded phone (e.g. Nexus or Pixel handsets). Right now Android O is available to download in beta. Here's how to update your Android phone, for everything you need to know.

How can I change the look and feel of my Android phone desktops?

Android phones from the likes of Huawei, LG and Samsung all sport a very different look and feel to the stock Android found on Google's own Pixel phones. That's because each manufacturer tends to add their own software overlay to Android, known as a 'launcher', which changes the design of the home screen, additional desktops, app logos and so on.

Luckily, if you feel like refreshing your Android phone's software design, it's incredibly easy to pull off. Just check out our guide to changing your Android launcher to learn how.

What is Android TV?

As the name kind of suggests, Android TV is based on the same Android software found on mobile phones but tweaked to work on TV streaming devices. For example, the Nvidia Shield TV runs off Android TV. This smart box connects to your telly and offers you full access to apps, games and the web. You can even perform searches for all kinds of content.
