What Is an Android Device?

Android devices are more customizable—and more affordable

Android—a mobile operating system maintained by Google—powers a range of smartphones and tablets including those manufactured by Google, Samsung, LG, Sony, HPC, Huawei, Xiaomi, Acer and Motorola. All major cellular carriers offer phones and tablets running Android.

Launched in 2003, it has surpassed Apple's iOS to become the most popular mobile operating system in the world. There are several reasons for its quick rate of adoption, one of which is the price. You can buy an Android phone for as little as $50 if you don't need all the slick features some of the high-end Android phones offer (although many do rival the iPhone in price).

Beyond the benefits of a lower price, phones and tablets running Android are much more customizable—unlike the Apple constellation of products in which the hardware/software is completely integrated and tightly controlled, Android is much more open.

Key Features of Android Devices

All Android phones share some common features. They are all smartphones, meaning that they connect to Wi-Fi, support touchscreens, access a range of mobile apps, and offer persistent customization. The similarities stop there, however, because any manufacturer can produce a device with its own "flavor" of Android, stamping its look and feel over the basics of the OS. 

Android Apps

All Android phones support Android apps, available through the Google Play Store. As of June 2016, it was estimated that there were 2.2 million apps available, compared to 2 million apps on Apple's App Store. Many app designers release both iOS and Android versions of their apps since both types of phones are so commonly owned. 

Apps include not only the obvious smartphone apps we all expect—such as music, video, utilities, books, and news —but also those that customize the very innards of an Android phone, even changing the interface itself. 

Android Versions & Updates

Google releases new versions of Android approximately every year. Each version is whimsically named after candy, along with its number. Early versions, for example, included Android 1.5 Cupcake, 1.6 Donut, and 2.1 Eclair. Android 3.2 Honeycomb was the first version of Android designed for tablets, and with 4.0 Ice Cream Sandwich, all Android systems have been capable of running on either phones or tablets. 

If you own an Android device, it will alert you when an OS update is available. Not all devices can upgrade to the newest version, however. Upgrade paths depend on your device's hardware and processing abilities, as well as the manufacturer and the mobile carrier. For example, Google provides updates first to its own Pixel line of phones and tablets. Updates are always free and installed through the internet.
