Check Your Current Android Version and Available Updates

Before you update, find out what version of Android your tablet is running and whether an update is waiting for you. Open Settings, scroll to the bottom, and tap About tablet. You will see your current Android version listed there — it will be a number like 11, 12, or 13, sometimes followed by a letter.

Next, check for updates in the same Settings menu. Go back to the main Settings screen, scroll down, and look for System or System and device update (the exact name varies by tablet brand). Tap it, then tap System update or Check for updates. Your tablet will connect to the internet and search for a newer version. If one is available, you will see it listed with the version number and file size.

Write down the current version before you start, in case you need to troubleshoot later. Take a screenshot if that is easier.

Key Takeaways

  • Updates are found in Settings > System > System update, and your tablet must be connected to Wi-Fi before the read begins.
  • Plug your tablet into power before you start the update, because the process can take 30 minutes to an hour and a dead battery will interrupt it.
  • Do not turn off your tablet, close apps, or unplug it while the update is running, or you risk corrupting the system.
  • After the update finishes and your tablet restarts, check Settings > About tablet again to confirm the new version installed.

Prepare Your Tablet Before Updating

Updates require a stable internet connection and enough battery power to complete. Connect your tablet to Wi-Fi — cellular data is too slow and unreliable for a system update. Then plug it into a charger. Even if your battery shows 80 or 90 percent, plug it in anyway. The update process can take 30 minutes to over an hour, and if the battery dies halfway through, your tablet may fail to start or lose system files.

Back up your photos, documents, and other files you care about. Most updates do not erase your data, but a failed update occasionally does. If you use Google Photos, Google Drive, or another cloud service, make sure your recent files have synced. You can also connect your tablet to a computer and copy files to your hard drive as a second backup.

Close all open apps before you begin. Swipe up from the bottom of the screen (or tap the back arrow, depending on your tablet) to close each app. This frees up memory and reduces the chance of a conflict during the update.

read and Install the Update

Go to Settings > System > System update and tap Check for updates again. If an update is available, you will see a button that says read or Update. Tap it. Your tablet will read the update file — this is the step that takes the longest, usually 10 to 30 minutes depending on file size and Wi-Fi speed.

Once the read is complete, your tablet will prompt you to install it. Tap Install or Restart and install. Your tablet will restart automatically, and you will see a progress bar on the screen. The bar may say "Installing system update" or show a percentage. Do not interrupt this step — leave your tablet plugged in and do not turn it off.

The installation can take 20 to 60 minutes. Your tablet may restart more than once. This is normal. Wait until you see your home screen again and the progress bar is gone.

Verify the Update Completed Successfully

After your tablet restarts and you are back at the home screen, open Settings again and go to About tablet. Check the Android version number. It should be higher than the version you wrote down before you started. If it matches the new version you saw in the update notification, the update installed correctly.

Your apps may take a few minutes to reopen fully, and you might see a notification that your device is optimizing apps. This is normal and happens automatically after every major update. Do not close this notification or turn off your tablet — let it finish on its own.

If the version number did not change, or if your tablet is stuck on a loading screen, restart it by holding the power button for 10 seconds until it shuts down, then press the power button again to turn it back on. If the problem continues, contact your tablet manufacturer's support line.

What to Do If the Update Fails or Gets Stuck

If your tablet gets stuck on a loading screen or the update does not complete after an hour, force a restart. Hold the power button down for 10 to 15 seconds until the screen goes black and the tablet shuts down. Wait 30 seconds, then press the power button to turn it back on. Your tablet will restart, and the system will usually finish the update on the next boot.

If the update fails repeatedly, try downloading it again. Go back to Settings > System > System update and tap Check for updates. Sometimes a partial read causes the failure, and starting over fixes it. Make sure you are still connected to Wi-Fi and plugged into power.

If you see an error message with a code, write it down and search for it along with your tablet model number on the manufacturer's website. Samsung, Amazon, and other tablet makers publish troubleshooting guides for specific error codes. If the problem persists after two attempts, contact the manufacturer's support team — they can walk you through a factory reset or other recovery steps if needed.

Understand What Changes After an Update

After a major Android update, your tablet may look or work slightly differently. The Settings menu layout sometimes changes, app icons may shift, and new features appear. These changes are normal. Your files, photos, and installed apps stay where they are.

Some older apps may not work with the new Android version. If an app crashes or will not open after the update, open the Google Play Store, search for the app, and tap Update if an update is available. The app developer usually releases a compatible version within days of a new Android release.

Your tablet may also run slower for a few hours after the update while the system optimizes itself. This is temporary. If performance does not improve after a day, restart your tablet once more.

Frequently Asked Questions

Can I update my tablet without Wi-Fi?

No. Android system updates are too large to read over cellular data, and the connection is not stable enough. You must use Wi-Fi. If you do not have Wi-Fi at home, you can update at a library, coffee shop, or friend's house — just make sure your tablet stays plugged into power the entire time.

Will the update erase my photos and files?

No. Updates preserve your data, apps, and settings. However, a failed update occasionally causes data loss, which is why backing up to Google Drive or another cloud service before you start is a good idea.

How often do Android updates come out?

Major Android updates (new version numbers) come out roughly once a year. Security updates and smaller fixes come out monthly or every few weeks. Your tablet will notify you when an update is available, but you can also check manually in Settings > System > System update anytime.

What if my tablet is too old to update?

Older tablets may not receive new Android versions. When you check for updates, if nothing appears, your tablet has reached the end of its update cycle. You can still use it, but it will not receive new features or the latest security patches. Contact your tablet manufacturer to confirm how long your specific model receives updates.

Do I have to update my tablet?

You do not have to, but security updates are important. They fix vulnerabilities that hackers can exploit. Major version updates add features and improve performance, but are not required. If your tablet works well and you prefer not to change anything, you can skip major updates — but install security updates when they appear.
