Where to find your Android version number

Your Android version lives in the Settings app, buried a few taps down. Open Settings, scroll to the bottom of the list, and tap About phone (some phones call it About device). Look for the line that says Android version — that number is what you need. It will look something like "14" or "13.1" depending on how recently your phone received updates.

The exact path varies slightly by manufacturer. Samsung phones sometimes label it About phone under General. Google Pixels go straight there from the main Settings menu. If you cannot find it after scrolling to the bottom of Settings, try using the search box at the top of Settings and type "Android version" — most phones will jump you directly to it.

Write down or screenshot the version number you find. You will need it to know whether your phone has the latest security patches and to understand what features are available to you.

Key Takeaways

  • Your Android version number is in Settings > About phone, listed as "Android version" with a number like 13, 14, or 15.
  • The build number (a longer string of characters below the version) tells you when your phone last received a security update, and older build numbers mean older patches.
  • Checking your version takes 30 seconds and tells you whether your phone is current enough to receive new features and security fixes.
  • If your version is more than two years old, your phone may stop receiving updates entirely, which affects both features and safety.

What the build number tells you about security updates

Below the Android version number, you will see Build number — a longer string that looks like "UP1A.231005.007" or similar. This is the real fingerprint of how current your phone is. The date embedded in that string (in this example, 2023, October, 5th) tells you the last day your phone received a security patch.

Security patches come out monthly, sometimes more often if a serious vulnerability is discovered. If your build number is from more than three months ago, your phone is missing patches that fix real exploits. This matters because malware and scams often target known vulnerabilities that patches have already closed. A phone with an old build number is easier to compromise.

You can check when your phone last received an update by looking at the build date, but the easiest way to know if you are current is to go to Settings > System > System update (or About phone > Software update on some phones) and tap the button to check for updates. If nothing is available, your phone is as current as the manufacturer has made it.

Why manufacturers stop updating phones at different times

Android phones do not all receive updates for the same length of time. Google Pixels typically get three years of major Android updates and three additional years of security patches — six years total. Samsung phones get four years of major updates and five years of security patches. Older budget phones might get only one or two years of updates before the manufacturer stops releasing them entirely.

This matters because once updates stop, your phone becomes a fixed target. Vulnerabilities discovered after the last update cannot be patched. If you own a phone that is four or five years old, check your version number now — you may already be past the point where updates are coming. That does not mean your phone is broken, but it does mean the risk of compromise grows over time.

You can usually find out how long your specific phone model will receive updates by searching "[your phone model] update schedule" or checking the manufacturer's website. Google publishes theirs publicly. Samsung does too. Smaller manufacturers are less transparent, which is another reason to check your current version and know what you have.

How to tell if your phone is too old to update

If you check for updates and the system says "Your system is up to date" but your build number is more than six months old, your phone has stopped receiving patches. This happens when the manufacturer decides to move on to newer models. It is not a failure — it is a business decision — but it changes what you should do with the device.

A phone that is no longer receiving updates is still usable for basic tasks like calling, texting, and browsing. But it should not be your primary device for banking, shopping, or storing sensitive documents. The longer a phone goes without patches, the more vulnerabilities accumulate in the operating system and built-in apps. Malware authors specifically target old versions because they know the holes will never be fixed.

If your phone is past its update window, you have two practical options: replace it with a newer model that will receive updates for several more years, or use it only for low-risk tasks and keep your sensitive activity on a newer device. Neither choice is wrong — it depends on your risk tolerance and budget.

What to do if your phone is several versions behind

If your Android version is two or more releases behind the current version (for example, you have version 12 but version 14 is current), your phone may still be receiving updates — or it may have fallen out of the update window. The only way to know is to check for updates in Settings.

Go to Settings > System > System update and tap Check for update. If updates are available, your phone will read and install them automatically, usually overnight. You may need to restart your phone to complete the installation. Do not interrupt this process — let it finish even if it takes an hour.

If you check and nothing is available, your phone has reached the end of its update life. This is normal and does not mean something is wrong with your device. It means the manufacturer has decided not to release any more updates for your model. At this point, the version number you see is the final version your phone will ever run.

How version numbers relate to features you can use

Newer Android versions unlock features that older versions cannot run. Android 14 introduced better battery management and more granular app permissions. Android 13 added per-app language settings. Android 12 brought Material You, which lets you customize the color scheme of your entire phone based on your wallpaper. If your phone is stuck on an older version, you straightforward cannot use these features — they do not exist in your version.

Some apps also require a minimum Android version to run. If you try to read an app and the Play Store says it is not compatible with your device, it is usually because your Android version is too old. Checking your version number tells you whether you can use new apps or whether you are locked out of them.

This is different from security — it is about capability. A phone on Android 12 is not unsafe compared to one on Android 14, but it has fewer features and may not be able to run newer apps. If you rely on a specific app for work or daily life, check its minimum requirements against your version before you assume your phone can run it.

Frequently Asked Questions

Is my phone unsafe if it is not on the latest Android version?

Not automatically. If your phone is one or two versions behind but still receiving security patches (check the build number date), you have the patches that matter. If your phone has stopped receiving updates entirely, the risk grows over time as new vulnerabilities are discovered and never patched. Age matters more than version number — a phone on Android 13 that gets monthly patches is safer than a phone on Android 14 that has not been updated in a year.

Why does my phone say it is up to date when I am not on the latest Android version?

Because your manufacturer has decided not to release that version for your model. Not all phones get every Android release. A two-year-old phone might be stuck on Android 12 while newer phones run Android 14. This is normal. "Up to date" means you have the latest version your manufacturer will release for your specific phone — not the latest version that exists.

Can I manually update my Android version if my phone is behind?

No. Android updates come only from your manufacturer through the Settings app. You cannot read them from anywhere else or install them manually without technical knowledge and risk to your device. If your phone says it is up to date, that is genuinely the latest version available for it.

What should I do with an old phone that no longer receives updates?

You can keep using it for low-risk tasks like calling, texting, or listening to music. Avoid using it for banking, shopping, or storing passwords and sensitive documents. If you want to repurpose it, factory reset it first to clear your data, then use it as a dedicated device for one low-risk task. Do not sell it without wiping it completely.

How often should I check my Android version?

Once when you first get a phone, then once or twice a year. You do not need to check constantly. If you notice your phone is acting slowly or you want to know if new features are available, checking takes 30 seconds. Most people benefit from checking once a year to know whether their phone is still in the update window.
