Check and update your Android version

You can see your device's Android version number and check for Android software updates at any time.

Check what Android version you have

To see what version of Android you have:

  1. Open your device's Settings app Settings.
  2. Scroll to the bottom and tap About phone or About tablet.
  3. Under "Android version", the number shown is your device's Android version number.

Get the latest Android updates

When a new Android system update is available for your device, you'll get a notification.

Tip: During Android updates, plug in your device and connect to Wi-Fi.

Update when you get a notification

To download and install an Android update after you get a notification:

  1. Open the notification.
    • If your device is locked, double tap the notification on the lock screen.
    • If your device is unlocked, swipe down from the top of any screen.
  2. To start the update, tap Download.
Update without a notification

To check for and install available Android updates:

  1. Open your device's Settings app Settings.
  2. Scroll to the bottom and tap About phone or About tablet and then System updates.
  3. Tap Check for update. If an update is available, tap Download.

Can't download or install latest Android update

If you get an update notification, but your device won't install the latest Android version, try these troubleshooting steps.

Clear space after "insufficient storage available" message

If a message says that your device can't update because it has insufficient storage available, try clearing your apps' cached data.

Clearing cached data won't delete any personal information.

To clear your apps' cached data:

  1. Open your device's Settings app Settings.
  2. Scroll down and tap Storage & USB and then Cached data.
  3. When asked if you want to clear cached data, tap OK.

If you still don't have enough storage space for the update after clearing cached data, you can uninstall apps that you don't use. You can also delete downloaded files. Find out how to optimise memory use on your device.

Try again after an unsuccessful update

If an update doesn't install successfully, your device will automatically try again over the next few days. You may not see the update as available in your Settings app until your device is ready to automatically try again.

To manually check for the update again after an unsuccessful installation:

  1. Wait at least 24 hours.
  2. Open your device's Settings app Settings.
  3. Scroll to the bottom and tap About phone or About tablet and then System updates.
  4. Tap Check for update. If the update is available, tap Download.

Timing for Android software updates

When new updates reach your device depends on your device type and your operator.

Nexus devices

  • Nexus 5X
  • Nexus 6P
  • Nexus 6
  • Nexus 5
  • Nexus 4

After an update is available, it can take up to two weeks to reach your device. Based on your operator, it may take longer than two weeks after release to get an update.

Security patches

  2. Scroll to the bottom and tap About phone or About tablet.
  3. Under "Android security patch level", see the date of your device's latest security patch.

Android One devices

Android One phones get the latest version of Android from Google's hardware partners. Google's partners send updates based on their schedules, trying to get them to you as soon as possible.

When will your Android One get updates?

After an update is available, it can take up to two weeks to reach your phone. When the update is ready to be installed on your phone, a message on your phone will say, "System update available." You'll need to connect to the Internet to get the notification and to download the software.

For how long will your Android One get updates?

All partners have committed to giving software updates for at least 18 months after the phone's launch. All Android One phones will get at least one major software update and several smaller security updates.

Google Play edition devices

Google Play edition devices get updates from the device manufacturers, not directly from Google. Google works closely with the manufacturers to provide system updates shortly after a new Android version is released.

When will your device get updates?

After an update is available, it can take up to two weeks to reach your device. Based on your operator, it may take longer than two weeks after release to get an update.

For how long will your device get updates?

Google Play edition devices may not receive the latest version of Android if they fall outside of the update window, which is usually around 18 months after a device has been released.
