HOW TO UPGRADE YOUR ANDROID OS

   Open your device’s Settings. You can find the Settings app in your app drawer, or you can press your device’s menu button when you are on the Home screen and select Settings.
   • Android updates are typically only available through the device itself. There are some exceptions, such as downloading the update through Samsung Kies on your computer for Samsung devices. Updating happens automatically on Kies if there is an update available when you connect your device to your computer via USB.

   Tap “Update”. This may also be labeled “Check for updates”. Your device will check to see if any updates are available. Update availability is dependent on your device’s manufacturer as well as your mobile service provider. New updates may not always be available for all devices.
   • If there is an update available, the update will begin downloading to your device. For larger updates, this could take awhile, and you should have your device connected to a Wi-Fi network so that you avoid going over your data allotment.

   Tap “Restart & install”. Once the update has finished downloading, the device will need to restart in order to install the software. This will render your device inoperable for a few minutes during the update process.^[1]
   • Plug your device into its charger during the installation process to ensure that the battery doesn’t run out while the update is being installed.
