Is it Chrome, or Safari, and how should I be able to know?

I know a UA can be spoofed, but let's assume it isn't, as it's just from a typical user who would have no reason to - but I'm trying to debug an odd JS quirk and it'd be useful to know which browser they were using.

Thank you

    SM-A202F is a Samsung smartphone product number: samsung.com/levant/support/model/SM-A202FZBDSEE ; if not spoofed you then know what model was in the hand of your visitor.

  • That bit I'd figured out - it was whether they're using Chrome or Safari that foxed me. Of course, I know there's no Android Safari app, officially anyway.

Below is the syntax for the User Agent header:

User-Agent: Mozilla/5.0 (<system-information>) <platform> (<platform-details>) <extensions>

In your case we have.

Mozilla/5.0 (Linux; Android 10; SM-A202F) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.101 Mobile Safari/537.36

Still doesn't tell the full picture though, we need to know the browser engine (also known as a layout engine or rendering engine).

https://developers.whatismybrowser.com/useragents/explore/operating_platform/sm-a202f/

So in your case we have:

  • Software: Chrome 91 (the software)
  • Layout Engine: Blink
  • Software Type: Web Browser
  • Popularity: Average

Blink is the name of the rendering engine used by Chromium

The browser is Chrome or chromium.

    Why do you doubt it's a typical user? I'm 99% certain that it is

    Additionally, could you explain to me why Safari is mentioned, if the browser used is Chome? Thank you!

    @Codemonkey Compatibility. Chrome (and Edge actually) use AppleWebKit. Sorry for the late reply!

    @Codemonkey Also I doubt that it was a typical user because I don't expect a regular person to be using Chromium. If your users are engineers and developers, then I'd recant my doubt.

    What about it says Chromium, as opposed to Chrome (which a significant portion of the public use)?

My guess is that it is a device in DevTools mode.

It look like a string that is store in the Firefox setting devtools.responsive.userAgent (accessible with about:config).
