If an Android update is available to your device you'll find it in your phone or tablet's Settings menu. However, just because a newer version of Android exists it doesn't mean it will be available for your device - now or ever.
That is entirely dependent on what device you have (and sometimes which operator you are with). Unfortunately, about two years into the device's lifetime you might see updates becoming rarer. There are no obligations from the manufacturers to support updates for older models.
Android is often criticised for its fragmentation. As of 8 January 2018 Android Developers reports the following stats, revealing that only 0.7 percent of Android devices in use are running the latest Oreo operating system:
|4.0.3-4.0.4||Ice Cream Sandwich||0.5%|
Back up your data
As a precautionary measure, it's good practice to back up your data such as contacts and photos. The upgrade shouldn't affect your data but there are no guarantees.
Check out our complete guide to backing up an Android device to find out how.
Navigate to the Settings menu on your device. On most Android devices this can be done via the app menu or notification bar.
Typically the Settings app will have a cog or spanner logo.
About Phone or Tablet
Scroll down the Settings menu and click on 'About Phone', 'About Tablet' or perhaps 'About Device'.
If you have a tabbed settings menu this will appear in the 'General' section.
The menu can vary from device to device, but look for and click the 'Software Update' or similar button.
Search for an update
Your phone or tablet will now search for an available update. If you are taken to another menu, select the 'Software update check' button or similar.
If an update is available your device then you will be asked whether you wish to install it. If you select yes then the system will download and install the new software and reboot.
Note: You device may require a Wi-Fi connection to search for an update. We also recommend downloading the software over Wi-Fi because the file size can be large.
