Chrome for Android User-Agent

Chrome for Android reports its user agent string (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
For comparison, here are examples of other popular user agent strings:

Desktop Chrome: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.151 Safari/535.19

Desktop Safari: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/534.53.11 (KHTML, like Gecko) Version/5.1.3 Safari/534.53.10

iPhone Safari: Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1A543 Safari/419.3

iPad Safari: Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.10

User agent mechanics

Like all other browsers, Chrome for Android Beta 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.

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

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