Example User Agent Strings mobile


User Agent Strings

A browser’s user agent string (UA) helps identify which browser is being used, what version, and on which operating system. When feature detection APIs are not available, use the UA to customize behavior or content to specific browser versions.

Like all other browsers, Chrome for Android sends this information in the User-Agent HTTP header every time it makes a request to any site. It’s also available in the client through JavaScript using the navigator.userAgent call.

Chrome for Android reports its UA in the following formats, depending on whether the device is a phone or a tablet.

Phone UA:

Mozilla/5.0 (Linux; <Android Version>; <Build Tag etc.>) AppleWebKit/<WebKit Rev> (KHTML, like Gecko) Chrome/<Chrome Rev> Mobile Safari/<WebKit Rev>

Tablet UA:

Mozilla/5.0 (Linux; <Android Version>; <Build Tag etc.>) AppleWebKit/<WebKit Rev>(KHTML, like Gecko) Chrome/<Chrome Rev> Safari/<WebKit Rev>

Here’s an example of the Chrome user agent string on a Galaxy Nexus:

Mozilla/5.0 (Linux; Android 4.0.4; Galaxy Nexus Build/IMM76B) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.133 Mobile Safari/535.19

If you are parsing user agent strings using regular expressions, the following can be used to check against Chrome on Android phones and tablets:

  • Phone pattern: 'Android' + 'Chrome/[.0-9]* Mobile'
  • Tablet pattern: 'Android' + 'Chrome/[.0-9]* (?!Mobile)'

The UA in Chrome for iOS is the same as the Mobile Safari user agent, with CriOS/<ChromeRevision> instead of Version/<VersionNum>.

Here’s an example of the Chrome UA on iPhone:

Mozilla/5.0 (iPhone; CPU iPhone OS 10_3 like Mac OS X) AppleWebKit/602.1.50 (KHTML, like Gecko) CriOS/56.0.2924.75 Mobile/14E5239e Safari/602.1

For comparison, the Mobile Safari UA:

Mozilla/5.0 (iPhone; CPU iPhone OS 10_3 like Mac OS X) AppleWebKit/603.1.23 (KHTML, like Gecko) Version/10.0 Mobile/14E5239e Safari/602.1

When the Request Desktop Site feature is enabled, the Desktop Safari UA is sent:

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_4) AppleWebKit/600.7.12 (KHTML, like Gecko) Version/8.0.7 Safari/600.7.12

The Android 4.4 (KitKat) Chromium-based WebView adds Chrome/_version_ to the user agent string.

Old WebView UA:

Mozilla/5.0 (Linux; U; Android 4.1.1; en-gb; Build/KLP) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Safari/534.30

WebView UA in KitKat to Lollipop

Mozilla/5.0 (Linux; Android 4.4; Nexus 5 Build/_BuildID_) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/30.0.0.0 Mobile Safari/537.36

If you’re attempting to differentiate between the WebView and Chrome for Android, you should look for the presence of the Version/_X.X_ string in the WebView user-agent string. Don’t rely on the specific Chrome version number (for example, 30.0.0.0) as the version numbers changes with each release.

WebView UA in Lollipop and Above

In the newer versions of WebView, you can differentiate the WebView by looking for the wv field as highlighted below.

Mozilla/5.0 (Linux; Android 5.1.1; Nexus 5 Build/LMY48B; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/43.0.2357.65 Mobile Safari/537.36
