Check your Galaxy's build

If you have a carrier model, I'd enter the full model number from Settings > About phone. Our Galaxy CSC guide shows where to find the code on your phone.

  1. Open SamUpdater and fill in Device name or model and Country or CSC code.
  2. Click Check update to see the build number, release date and security patch. Look under Software for the One UI and Android versions when Samsung includes them in the notes.
  3. On your Galaxy, go to Settings > About phone > Software information > Build number and compare it with the build in Chrome.

Scroll down to Latest releases for a quick look at other recent builds. Our Samsung firmware tracker has the longer list.

Frequently asked questions

Does the extension install Galaxy updates?

You install updates on the Galaxy itself. Open Settings > Software update > Download and install to see what's available for your phone. Samsung can list a build before it arrives on your carrier or in your region. Samsung's software update instructions.

What does SamUpdater send when I run a check?

When you click Check update, SamUpdater receives the model number and CSC you entered. Opening the popup also fetches the recent release feed. You can do both without signing in, and the extension omits cookies from both requests. Read the extension privacy policy.

If your lookup looks off, send us your model number and CSC and tell us what Chrome shows.
