I'm trying to find out what is the user agent of Samsung Galaxy S3.
I don't have the device so I can't test myself. The user agent is going to be recognized by my web server.
Published: 15 May 2022. 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.
User agent is a string of data from a user's device that represents data points like OS, browser, carrier, and hardware.
Switch to the “Advanced” tab in the top-right corner, then tap “User agent” at the top of the “Customize” sub-section. Tap “User agent” at the top of the “Customize” sub-section of the “Advanced” tab. Select one of the four built-in user agents or tap “Custom” and enter your own value, then tap “OK” to save.
In simple words, it's a string of text that is unique for each software or browser on the internet and holds the technical information about your device and operating system. User-agent is present in the HTTP headers when the browser wants to connect with the webserver.
Mozilla/5.0 (Linux; U; Android 4.0.4; en-gb; GT-I9300 Build/IMM76D) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30
What's My User Agent? is a great tool for figuring out what the User Agent of your current browser is. Just navigate to it in the browser of whatever device you want the UA for.
If you don't have the device you want to test, that site also has a section for Common User Agents. Once you figure out the UA you want to test, you can use the User Agent-Switcher for Chrome plug-in to have Chrome mimic that UA.
Full Disclosure: I don't work for or know the people who have created these tools, just figured I'd share some of the tools I use with the community : )
