What Does Your User Agent Say About You?

Archive

A user agent is a computer program representing a person, for example, a browser in a Web context.

Besides a browser, a user agent could be a bot scraping webpages, a download manager, or another app accessing the Web. Along with each request they make to the server, browsers include a self-identifying User-Agent HTTP header called a user agent (UA) string. This string often identifies the browser, its version number, and its host operating system.

Spam bots, download managers, and some browsers often send a fake UA string to announce themselves as a different client. This is known as user agent spoofing.

The user agent string can be accessed with JavaScript on the client side using the navigator.userAgent property.

A typical user agent string looks like this: "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:35.0) Gecko/20100101 Firefox/35.0".

We've got 22.5 million users agents for software running on Android. There is protection in place to stop the scraping of these user agent listings.

We've had to do this because otherwise we get constantly overrun by inconsiderate or malfunctioning bots which overload the system. As such, we're forced to block traffic from popular web hosting companies, VPNs and Proxies, we also rate limit requests and have some other checks too.

If you need to get access to the listings of user agents you can either get them in an easy-to-use database download or via the API. 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. Chrome for Android reports its UA in the following formats, depending on whether the device is a phone or a tablet.

The standard way to pass information to the server about the visiting device is to include it in the User-Agent (UA) string. Described in the HTTP standard, the User-Agent string contains a number of tokens that refer to various aspects of the request, including the browser’s name and version, rendering engine, device’s model number, operating system and its version, etc.

From a web developer’s perspective, User-Agent strings can be useful when it comes to testing how online content is rendered on various hardware and software combinations. The landscape of mobile browsers is quite complex, with several major players (pre-installed in most cases) and a number of locally popular contenders.

While all phones come with pre-installed browsers, both Google Play and Apple App Store offer a number of alternative browsers, some focusing on speed and lightness, others on saving bandwidth and blocking ads, and an ever-increasing amount claiming to increase privacy and reduce a users' mobile digital footprint. Feel free to browse the stats for your local market using our Data Explorer tool.

A simple regex solution searching for keywords will struggle in terms of accuracy and detection speed. To tackle these issues you may want to consider using a specialized device detection provider, such as Device Atlas.

If you have (or have ever used) a shared Windows PC, then you may already be familiar with the concept here: everyone has their own login, complete with their own apps and settings. Not a lot of people realize this, but Android has a very similar feature built in called User Profiles.

If you have a shared device and are into the idea, setting up a new user profile is easy-peasy. Tablets also offer an exclusive “Restricted Profile” for shared devices with kids.

To get started, go ahead and give the notification shade a tug, then tap the gear icon. On tablets, you’ll be asked to choose whether you want to add a regular account or restricted.

If you choose to set it up now, you’ll immediately be “logged out” of the profile you’re currently using and tossed into the setup menu. To enable this, log back into the admin account (instructions on profile switching are below) and jump into the Users' menu again.

Tap the cog icon next to the new user’s name, then toggle the “Turn on phone calls and SMS” option. To switch profiles, pull down the notification shade twice and tap the user icon.

The User-Agent (UA) string is contained in the HTTP headers and is intended to identify devices requesting online content. The User-Agent tells the server what the visiting device is (among many other things) and this information can be used to determine what content to return.

Of course this requires using a device detection solution which translates UAS into understandable software and hardware information. If you’d like to learn more on these devices, just copy and paste the UAS to our User-Agent testing tool.

The other way to sign in is using the Nest credential, however since I move to Google they don't seem to be working. Force close and reopen the Nest App.

Confirm the Nest app has permissions to use the phone's location. Check for and process any pending Android OS updates.

Pending OS updates may break some app functionality. Test for issue persistence on both Wi-Fi and cellular data, if applicable.

I can type www.nest.com into my Google Chrome browser and view my cameras, thermostat and smoke alarm through the website but this doesn't resolve the app not working issue.

Due to the app not working I am no longer receiving notifications when the cameras notice motion and I can't link the thermostat to my Alexa account to control it through the Alexa dots. I'm also unable to view previous video feed of motion caught on any of my cameras through the website so with the App not working all I have access to is a live feed when I take the time to login to the website.

Firefox OS phones say Mobile “; the web is the platform. On Desktop, gecko trail is the fixed string 20100101 Firefox/ firefoxversion indicates the browser is Firefox, and provides the version (such as 17.0 “).

For other products based on Gecko, the string can take one of two forms, where the tokens have the same meaning except those noted below: Appname / app version indicates the application name and version.

The platform part of the UA string indicates if Firefox is running on a phone -sized or tablet device. When Firefox runs on a device that has the phone form factor, there is a Mobile ; token in the platform part of the UA string.

The preferred way to target content to a device form factor is to use CSS Media Queries. This way, your code will work if/when Firefox ships on other phone /tablet operating systems or Android is used for laptops.

Firefox OS devices identify themselves without any operating system indication; for example: “Mozilla/5.0 (Mobile ; RV:15.0) Gecko/15.0 Firefox/15.0”. For increased interoperability, if the browser is running on a version below 4 it will report 4.4.

Some of them we have noticed are of the form Nelson; “, Reopen; “, or Open C; (note that putting space is also discouraged).

The first two digits are owned by the Mozilla product team and denote versions with new features (e.g.: v1.1, 1.2, etc). The third digit is incremented with regular version tags (about every 6 weeks) for security updates, and the fourth is owned by the OEM.

In the past, specific plug-ins, add-ons or extensions added user agent parts to notify sites they were installed. The recommended way to do this, if it's absolutely necessary (remember that it slows down every request) is to set a custom HTTP header.
