Check for updates in Settings

Open Settings on your Samsung Galaxy tablet. Scroll down and tap About tablet (or About device on some models). Look for an option called Software update or System update — the exact name varies by model and Android version.

Tap that option. Your tablet will check Samsung's servers for a newer version. If an update is available, you will see a button that says read or Update. If your tablet is already on the latest version, the screen will say "Your device is up to date" or similar.

Make sure your tablet is plugged into power before you start. Updates can take 15 to 45 minutes depending on file size and your internet speed, and a dead battery mid-update can damage the system.

Key Takeaways

  • Go to Settings > About tablet > Software update to check for and read new versions.
  • Plug your tablet into power before starting any update, since the process can take 30 minutes or longer.
  • Connect to Wi-Fi rather than mobile data, because updates are large files and Wi-Fi is more stable.
  • Do not turn off your tablet or close the app while an update is installing — let it finish completely.
  • If an update fails or gets stuck, restart your tablet and try again from Settings.

Connect to Wi-Fi before downloading

Updates are large files — often 500 MB to 2 GB — so a strong Wi-Fi connection is important. Mobile data can be slow or unstable, and if the connection drops mid-read, you may have to start over.

Open Settings and tap Wi-Fi. Select your network and enter the password if needed. Wait for the connection icon to appear in the status bar at the top. Then go back to About tablet and tap Software update again.

read and install the update

Once you tap read or Update, your tablet will pull the file from Samsung's servers. A progress bar will show how much has downloaded. This step usually takes 5 to 15 minutes on a good Wi-Fi connection.

When the read finishes, the screen will prompt you to install. Tap Install or Install now. Your tablet will restart automatically — this is normal. Do not unplug it or force it off. The installation process can take 10 to 30 minutes, and you will see a progress bar or Android logo on the screen.

Once installation is complete, your tablet will restart again and return to the lock screen. You can unlock it and use it normally. The update is finished.

What to do if the update fails

If the read stops or the installation freezes, restart your tablet. Press and hold the power button until the power menu appears, then tap Restart. Once it restarts, go back to Settings > About tablet > Software update and try again.

If the same update fails twice, try connecting to a different Wi-Fi network if one is available. Sometimes a network issue or weak signal causes the read to stall. If you still cannot get the update to work, contact Samsung support through their website — they can walk you through troubleshooting steps specific to your model.

Automatic updates and background installation

Some Samsung tablets are set to read updates automatically when connected to Wi-Fi and plugged in. You can control this in Settings > About tablet > Software update. Look for an option like Auto read over Wi-Fi or Automatic system updates and toggle it on or off depending on your preference.

If automatic read is on, your tablet will pull the update file in the background, usually overnight. You will still need to manually tap Install when prompted, or you can set it to install automatically as well. Either way, make sure your tablet is plugged in before you go to bed.

Free up storage space if the update will not read

Updates require temporary storage space to read and install. If your tablet is nearly full, the read may fail. Check how much space you have left by going to Settings > Storage or Settings > Device care > Storage.

If you have less than 1 GB free, delete files you no longer need — old photos, videos, or apps you do not use. You can also clear the cache for individual apps: go to Settings > Apps, select an app, and tap Storage > Clear cache. This removes temporary files without deleting your data. Once you have freed up space, try the update again.

Frequently Asked Questions

How often does Samsung release updates for Galaxy tablets?

Samsung typically releases security updates monthly and major system updates once or twice a year. The exact schedule depends on your tablet model and how old it is. Older models may stop receiving updates after three to four years.

Will updating erase my files and apps?

No. A standard software update preserves all your photos, videos, apps, and settings. Your tablet will look and work the same after the update, just with newer features and security fixes. A factory reset is different and does erase everything — that is not what a software update does.

Can I use my tablet while it is updating?

No. Once you tap Install, your tablet will restart and you cannot use it until the installation is complete. The process usually takes 10 to 30 minutes. Plan ahead and make sure you do not need the tablet for other tasks during that time.

What if my tablet gets stuck on the Samsung logo during an update?

Wait at least 10 minutes — some tablets take a long time to finish installation. If the logo is still there after 15 minutes, press and hold the power button for 10 seconds to force a restart. Then try the update again from Settings. If it gets stuck a second time, contact Samsung support.

Do I need to update my tablet if it is working fine?

Yes, you should install updates when they are available. Updates include security patches that protect your tablet from hackers and malware, even if you do not notice any problems. Delaying updates leaves your device vulnerable.
