Check for updates in Settings

The fastest way to update your Samsung phone is through the Settings app. Open Settings, scroll down to About phone, then tap Software update. Your phone will check whether a new version is available. If one is ready, you'll see a button to read and install it right away.

Samsung phones check for updates automatically in the background, usually overnight when plugged in and connected to Wi-Fi. But checking manually in Settings lets you see the status when ready and start the process on your schedule instead of waiting for the automatic check.

Before you tap the install button, make sure your phone battery is above 50 percent. Updates can take 15 to 45 minutes depending on the file size and your internet speed, and a dead battery during the process can cause problems.

Key Takeaways

  • Open Settings, go to About phone, then Software update to check for and install updates manually.
  • Connect to Wi-Fi before downloading an update, because the file is usually 500 MB to 2 GB and will drain mobile data quickly.
  • Charge your phone to at least 50 percent battery before starting an update, because the installation can take 15 to 45 minutes.
  • Your phone will restart several times during the update process, which is normal and expected.
  • After the update finishes, check Settings > About phone > Software version to confirm the new version number installed correctly.

Connect to Wi-Fi before downloading

Samsung updates are large files—typically between 500 MB and 2 GB depending on your phone model and which version you're updating to. Downloading over mobile data will consume your monthly allowance quickly and may be slower than Wi-Fi. Always connect to a reliable Wi-Fi network before tapping read.

If you're away from home Wi-Fi, wait until you reach a place with a strong connection. A weak or interrupted read can stall partway through, and restarting a partial read wastes time and data. Once the read finishes, the installation happens on your phone itself and doesn't need the internet.

What happens during the installation

After you tap Install, your phone will restart automatically—usually two or three times. The screen will show a Samsung logo and a progress bar. This is normal. Do not turn off your phone, remove the battery, or interrupt the process. Leave it plugged in and let it finish, even if it seems to be taking a while.

The entire process from read to completion typically takes 15 to 45 minutes. Newer phones and smaller updates are usually faster. Older phones or very large updates can take closer to an hour. During this time, you won't be able to use your phone for calls, texts, or apps.

Once the installation finishes, your phone will restart one final time and return to your home screen. You may notice a brief setup screen asking you to confirm your lock pattern or password—this is a security step and is normal after a major update.

Verify the update installed correctly

After your phone restarts and settles, open Settings again and go to About phone > Software version. Write down or take a screenshot of the version number shown. Compare it to the version number that was listed before the update. If the number has changed, the update installed successfully.

Your phone may also show a notification or banner saying the update is complete. You can dismiss this. If you see an error message or the version number hasn't changed, the installation may have failed. In that case, try the update again from Settings > Software update.

Update Samsung apps separately

The system update you install from Settings updates the Android operating system and Samsung's built-in apps like Messages, Phone, and Samsung Internet. But Samsung also releases updates to individual apps like Samsung Health, Samsung Notes, and Samsung Keyboard through the Google Play Store.

To update these apps, open the Google Play Store app, tap your profile icon in the top right, then tap Manage apps and device. Go to the Updates available tab to see which apps have newer versions. You can update them one at a time or tap Update all to install everything at once.

Troubleshooting a stuck or failed update

If your phone gets stuck on the Samsung logo screen during an update, or if the installation fails and you see an error code, try restarting your phone first. Hold the power button until the restart menu appears, then select Restart. Once it boots back up, go to Settings > Software update and try again.

If the same error appears a second time, your phone may have a connection problem or not enough storage space. Check that you have at least 2 GB of free space by going to Settings > Storage. If storage is full, delete old photos, videos, or apps you don't use, then try the update again.

If the update still fails after clearing space and restarting, contact Samsung Support through the Members app (pre-installed on most Samsung phones) or visit Samsung's website for your region. They can walk you through a manual update using a computer if needed, though this is rarely necessary.

When updates arrive and how often

Samsung releases major Android updates once a year, usually in the fall. These updates bring new features and significant changes to how your phone works. Security updates—which fix vulnerabilities without adding new features—arrive monthly or more often depending on what threats emerge.

Newer Samsung phones (usually the last two to three years of models) receive updates faster than older ones. A flagship phone like the Galaxy S series typically gets the new Android version within weeks of its release. Mid-range and budget models may wait several months. Your phone will notify you when an update is available, but you can also check manually anytime in Settings.

Frequently Asked Questions

Can I use my phone while it's updating?

No. Your phone will restart multiple times during the update and you won't be able to make calls, send texts, or open apps. The update usually takes 15 to 45 minutes. Plan to leave your phone alone during this time and keep it plugged in.

What if I turn off my phone during an update?

Turning off your phone during an update can corrupt the system files and leave your phone in an unusable state. Always let the update finish completely, even if it takes longer than expected. If your phone does shut down unexpectedly, plug it in and restart it, then try the update again from Settings.

Do I lose my photos and data when I update?

No. System updates do not erase your photos, messages, contacts, or apps. Your personal data stays on your phone. However, it's always a good idea to back up your phone to Samsung Cloud or Google Drive before any major update, just in case something goes wrong.

Why is my phone asking for my password after the update?

This is a security feature. After a major update, Samsung requires you to enter your lock screen password or pattern to confirm your identity. This protects your phone if it was lost or stolen during the update process. Enter your password as you normally would.

Can I schedule an update for a specific time?

Samsung phones don't have a built-in scheduler for updates. However, you can manually start the update whenever you want by going to Settings > About phone > Software update. Choose a time when you won't need your phone for 30 to 60 minutes.
