Check Your Current Software Version and Available Updates
Before you start, find out what version of Android your tablet is running and whether an update is waiting for you. Go to Settings, then scroll down and tap About tablet. Look for the line that says Android version — that's what you have now. The build number appears just below it.
Now check whether Samsung has released something newer. Stay in Settings, scroll back up, and tap Software update. Your tablet will connect to Samsung's servers and tell you whether an update is available. If one is there, you'll see the version number and file size. If your tablet says "Your software is up to date," you're already running the latest version and don't need to do anything.
Write down the current version number before you start — it helps if something goes wrong and you need to describe what happened to Samsung support.
Key Takeaways
- Updates appear in Settings under Software update, and your tablet checks automatically, but you can also check manually whenever you want.
- Connect to Wi-Fi before starting an update — the file is usually 500 MB to 2 GB, and using mobile data can be slow and expensive.
- Plug your tablet into power or charge it to at least 50 percent before you begin, because the update will fail if the battery dies partway through.
- The update process takes 10 to 30 minutes depending on file size, and your tablet will restart several times — do not unplug it or force it off.
- If an update stalls or your tablet gets stuck on a loading screen, hold the power button for 10 seconds to force a restart, then try the update again.
Prepare Your Tablet Before You Update
Updates require a stable internet connection and enough power to complete the entire process. Connect to a Wi-Fi network you trust — updates are large files, and downloading over mobile data is slow and can drain your monthly allowance. If you're on a metered connection, wait until you're somewhere with unlimited Wi-Fi.
Charge your tablet to at least 50 percent battery, though plugging it in during the update is safer. If the battery dies while the update is installing, your tablet may not start up properly afterward, and you could lose data or need professional repair. Leave your tablet plugged in for the entire update process.
You don't need to delete apps or photos — updates don't erase your files — but if your storage is almost full (less than 1 GB free), the update may fail. Check your storage by going to Settings, then Storage. If you're running low, delete old photos, videos, or apps you don't use, then try the update again.
read and Install the Update
Go back to Settings, tap Software update, and tap read and install (or Update, depending on your tablet model). Your tablet will read the file — this usually takes 5 to 15 minutes on a fast Wi-Fi connection. Do not close Settings or turn off your tablet while it's downloading.
Once the read finishes, your tablet will ask whether you want to install now or later. Choose Install now. Your tablet will restart automatically and show a progress bar while it installs the update. This part takes 10 to 20 minutes. You'll see the Samsung logo and a loading animation — this is normal. Your tablet may restart two or three times during installation.
Leave your tablet alone and plugged in until you see your home screen again. Do not press buttons, do not unplug the charger, and do not force the tablet off. If the progress bar hasn't moved in 30 minutes, or if your tablet is stuck on the same screen for more than 45 minutes, then you can force a restart by holding the power button for 10 seconds.
What to Do If the Update Stalls or Fails
If your tablet gets stuck on a loading screen or the update seems frozen, force a restart by holding the power button for 10 seconds until the screen goes black. Wait 30 seconds, then turn it back on. Your tablet will usually resume the update from where it left off, or it will roll back to the previous version and you can try again.
If the update fails and your tablet restarts but still shows the old version number, go back to Settings and try downloading the update again. Sometimes the file was corrupted during read, and a second attempt works. Make sure you're on a strong Wi-Fi connection this time.
If the same update fails three times in a row, or if your tablet won't turn on after an update attempt, contact Samsung support. You can reach them through the Samsung Members app (which comes pre-installed on most Galaxy tablets) or through Samsung's website. Have your tablet's model number and serial number ready — you'll find both in Settings under About tablet.
Verify the Update Installed Correctly
Once your tablet restarts and you're back at the home screen, go to Settings and tap About tablet again. Check the Android version line — it should show the new version number you saw before you started. If it matches, the update installed successfully.
Your tablet may take a few minutes to finish organizing files in the background after an update, so it might feel slightly slower for the first hour. This is normal and goes away on its own. If your tablet is still slow after a full day, restart it once more by holding the power button and tapping Power off, then turning it back on.
Turn On Automatic Updates So You Don't Have to Remember
Samsung can read and install updates automatically if you let it. Go to Settings, tap Software update, then look for Auto read over Wi-Fi or Automatic system updates (the exact name varies by model). Turn this on, and your tablet will read updates in the background when you're on Wi-Fi and plugged in.
When an automatic update is ready to install, your tablet will notify you and ask for permission. You can choose to install when ready or schedule it for later — for example, you can tell it to install at 2 a.m. so it doesn't interrupt you during the day. This way you always have the latest security patches without having to remember to check manually.
Frequently Asked Questions
Can I use my tablet while it's updating?
No. Once the installation begins, your tablet will restart and lock you out until the update finishes. The entire process takes 10 to 30 minutes depending on file size. Do not try to use your tablet, close apps, or turn it off during this time.
Will the update erase my photos, apps, and files?
No. Updates install on top of your existing software and leave all your personal data, apps, and settings in place. Your tablet will look and work the same after the update, just with newer security fixes and sometimes new features.
What if I don't want to update my tablet?
You can skip individual updates, but Samsung eventually stops supporting older versions. Older software has known security problems that hackers can exploit. Updates are free and designed to keep your tablet safe, so it's worth installing them when they arrive.
How often does Samsung release updates for Galaxy tablets?
Samsung releases security updates monthly and major Android updates once or twice a year. The frequency depends on your tablet's age — newer models get updates for longer. You'll see a notification when an update is available, or you can check manually in Settings anytime.
What should I do if my tablet won't turn on after an update?
Hold the power button for 15 seconds to force a restart. If that doesn't work, plug it into power for 30 minutes, then try again. If your tablet still won't start, contact Samsung support — this is rare, but they can walk you through recovery steps or arrange a repair if needed.
