If you own a smartphone, chances are that your device is running a version of Android, the open source mobile operating system developed by Google.
Besides the many older versions of Google-created Android software, there are also many so-called “forked” versions of Android that have been customized by various smartphone manufacturers.
Visit your smartphone maker’s website and search the model number to learn more about the update process for your device.
Before you update any device, it’s always a good idea to back up your data.This means that you will be unable to get the latest version of the Android operating system unless you root your Android smartphone to enable software upgrades.Most manufacturers that offer Android updates will deliver them via the device’s System Update function, as seen in the screenshot above.In general, the newer, high-end smartphones made by well-known companies are more likely to offer the ability to upgrade Android than the low-end devices made by lesser known companies.
One notable exception to this general rule is Google’s line of Nexus devices.
While Android comes in many different versions on a wide variety of smartphones, most devices should feature a Settings icon on the home screen.
