Samsung Internet user agent
Samsung Internet is the default browser on many Samsung Android devices. Built on Chromium, its user agent looks Chrome-like but carries a SamsungBrowser product token. That token is how you recognise Samsung Internet traffic, which is a meaningful share of mobile visits on Samsung hardware.
The Samsung Internet UA pattern
Samsung Internet is built on Chromium, so its user agent carries the usual Mozilla prefix, an Android platform descriptor, an AppleWebKit token, and a Chrome product token. It distinguishes itself with a SamsungBrowser token and its own version.
Match on the SamsungBrowser token to identify it. Because it also carries a Chrome token and an Android Mobile descriptor, a naive rule would otherwise count it as mobile Chrome.
- Chromium-based mobile browser on Android
- Distinguishing marker: a SamsungBrowser token
- Also carries Chrome, AppleWebKit, and Android Mobile tokens
Why it is worth recognising
Samsung Internet ships as the default browser on a large installed base of Samsung Android devices, so on sites with significant mobile traffic it can be a non-trivial share. Treating it as generic Chrome hides that segment in your browser breakdown.
Match on the stable SamsungBrowser pattern rather than a full version string, and confirm specifics against Samsung's developer documentation since UA detail changes between releases.
How it appears in analytics and logs
A mobile user agent with Chrome and AppleWebKit tokens plus a SamsungBrowser token is Samsung Internet. The SamsungBrowser marker is what separates it from mobile Chrome.
Diagnostic use case
Recognise Samsung Internet in mobile traffic by its SamsungBrowser token so Samsung's default browser is not miscounted as Chrome.
What WebmasterID can help detect
WebmasterID recognises Samsung Internet server-side from its SamsungBrowser token and records a coarse browser category, so it is not silently merged into mobile Chrome.
Common mistakes
- Counting Samsung Internet as mobile Chrome because both carry a Chrome token.
- Hard-coding a full SamsungBrowser version string that changes each release.
- Assuming all Android Chrome-token traffic is Google Chrome.
Privacy and accuracy notes
The Samsung Internet user agent describes the browser and device class, not a person. WebmasterID stores a coarse browser/device category, not a real visitor's raw string.

- Mobile user agents: phones, tablets, in-app
Mobile user agents carry platform descriptors like iPhone or Android and often a Mobile token, but tablets and in-app browsers complicate the picture. An in-app browser (inside a social or messaging app) usually adds its own token to the string. This page explains the patterns and their pitfalls.
- Chrome user agent and its quirks
Chrome's user-agent string is full of historical artefacts: it claims AppleWebKit and Safari for compatibility even though Chrome uses the Blink engine. Google has also reduced the detail Chrome exposes in the UA, moving fine-grained information into User-Agent Client Hints. This page explains the pattern and the quirks.
