Why updating your Samsung phone matters
- Security: monthly patches fix vulnerabilities that hackers use.
- New features: One UI updates add new tools, Galaxy AI features and design changes.
- Performance: updates often fix bugs and improve battery life.
Before you update
- Back up your phone. Use Samsung Cloud, Google backup or Smart Switch on a computer.
- Charge to at least 50%, or keep the phone plugged in.
- Connect to Wi-Fi. Major updates can be several gigabytes.
- Free up storage. You need extra space for the download. See how to free up storage on Android.
How to update Samsung phone software over the air
- Open Settings.
- Scroll down and tap Software update.
- Tap Download and install.
- If an update is available, tap Download, then Install now.
- Your phone restarts. The installation can take 10 to 30 minutes.
Tip: turn on Auto download over Wi-Fi on the same screen so future updates download automatically.
How to check which One UI version you have
Open Settings › About phone › Software information. You will see your software version, Android version and security patch date.

How to update Samsung phone software with Smart Switch
If the over-the-air update won’t install, use a computer.
- Install Samsung Smart Switch on your Windows PC or Mac from Samsung’s website.
- Connect your phone with a USB cable.
- Open Smart Switch. If an update is available, it shows an Update button.
- Follow the instructions and keep the phone connected until it finishes.
Samsung explains both methods on its official support page.
Why isn’t the latest One UI update showing?
- Staged rollout: Samsung releases updates in waves by region, model and carrier. Africa often gets updates a few weeks after other regions.
- Carrier versions: locked phones wait for carrier approval.
- Not eligible: older models stop receiving major updates.
- Region mismatch: imported phones may follow another country’s schedule.
How to update Samsung apps
Updating the system is only half the job. Samsung’s own apps update separately through the Galaxy Store.
- Open the Galaxy Store app.
- Tap Menu, then Updates.
- Tap Update all.
Google apps update through the Play Store in the same way. Keeping both up to date gives you the latest features and fixes.
Security updates vs major updates
Samsung releases two kinds of software update:
- Security updates: small monthly or quarterly patches that fix vulnerabilities. Install them as soon as they appear.
- Major updates: new versions of Android and One UI with new features and design changes. These are larger and arrive about once a year.
Even when a phone stops getting major updates, it may still receive security patches for a while longer.
What to do if an update fails
- Restart the phone and try again.
- Free up more storage space.
- Switch to a stable Wi-Fi network.
- Try Smart Switch on a computer.
- Visit an authorised Samsung service centre if the phone won’t boot.
After updating
Give the phone a day to settle. Battery life can seem worse at first while the phone optimises apps. Then follow our tips on how to make your phone battery last longer, and review our phone security tips.
Frequently asked questions
How often does Samsung release updates?
Security updates arrive monthly or quarterly, depending on the model. Major One UI updates arrive about once a year.
Will updating delete my data?
No, a normal update keeps your data. Still, always back up first.
Can I go back to an older One UI version?
Not easily. Downgrading is not officially supported, so read about an update before installing it.
Is it safe to install a beta version?
Beta software can contain bugs and may drain the battery or break apps. Only join a beta on a spare device, and always back up your data before you try one.
