Update Android software

For best performance, keep your phone updated with the latest available Android software.

Check Android version number

To check what version of Android your phone is running:

  1. Go to Settings > About phone > Android version.
  2. The number displayed is your phone's Android version.

Install Android software updates

Your phone notifies you if an Android software update is available.

To manually check for updates, go to Settings > About phone > System updates.

If an upgrade is available, follow the onscreen instructions to install it.

Tips
  • To save data charges, use a Wi‑Fi connection to download software updates.
  • For safety reasons, your phone may download security updates (not OS upgrades) automatically over your mobile network if Wi-Fi is not available within a few days after you receive a notification that a security update is available. In this case, data charges may apply depending on the carrier.

You can't downgrade to a previous software version after installing an update.
