Note: If there is more than one download option, that likely means that you need to download and install the Bug Fix Update for your smartphone or tablet device before you can actually update to Android 12.
Step 1:Before you go trying to update your device, you should check which version of Android you are running. You might already be on the latest version. It's easy to check so follow this guide up to step four. This screen will have a section called 'Android version'. If it doesn't, click 'Software information' to find out.
Step 2:Scroll down the Settings menu and click on 'About Phone' or 'About Tablet'. If you have a tabbed settings menu then this will appear in the 'general' section.
Refer to Android developer page to choose which version of Android your phone or tablet is running. I.e, 4.0.4 corresponds to Ice Cream Sandwich, an old version of Android that was released in 2013.
Step 3:Note: Your phone or tablet may require a Wi-Fi connection to search for an update. We suggest you to download the software Droid Over Wi-Fi because the file size can be large.
Choose and click the "Software Update" option. Next it will search available update for your phone or tablet. If update is available, you will be asked if you want to install it. Select "yes" and it will install the new operating system in your device. If you want to install it later, you can download the Android 12 file first. Download Android 12.zip
