The User-Agent header of s ome microbrowsers also contains the word "Mozilla". For example, some Nokia cell phones use a "Mozilla compatible" User-Agent header. The reason is that Nokia is a web-compatible cell phone and can accept HTML content, but some websites that are designed for desktops will deny access to Nokia if the "Mozilla compatible" User-Agent header is not present. To increase accuracy, you can further check the OS name and browser name in the User-Agent header. For example, if you find the word "Mozilla" and the OS name "Windows NT" in the User-Agent string, it is almost certain that the user agent is a web browser on a computer but not on a mobile device; if you find the word "Mozilla" and the browser name "Firefox" , it is certain that the user agent is a Firefox browser running on a computer since Firefox does not have a mobile device version at the time of this writing.

Cheery Cheery Bert It checks the browser by the User-Agent string submitted with every request. When browser does not send the identification in UA you can not detect it even with javascript. Only, probably, taking into account the screen resolution. But you do not need to know what kind of device it is, only if it is mobile or not. Here is the code for the mobile device detection.
Let's have a look at the user agent on the browser. Then it's probably not a mobile device. On desktop operating systems, Microsoft Edge is commonly identified by the Edg token in the User-Agent string. However, a different token for Microsoft Edge is used on some device platforms, as follows:. Map the User-Agent string tokens to human-readable browser names to use in code.
This practice is common across the web. When you map the new Edg token to a browser name, Microsoft recommends using a different name than the one used for the legacy Microsoft EdgeHTML browser, to avoid accidentally applying legacy workarounds that don't apply to Chromium-based browsers. Sometimes, a website doesn't recognize the Microsoft Edge user agent. As a result, a set of the features of the website may not work correctly. When Microsoft is notified about the types of issues, Microsoft contacts you a website owner and informs you about the updated user agent.
You may need more time to update and test the user agent detection logic for your website to address the issues reported by Microsoft. To maximize compatibility for your users, the Microsoft Edge Beta and Stable channels use a list of user agent overrides. Use the user agent overrides while you update your website. The list of user agent overrides is provided by Microsoft. The overrides specify new user agent values that Microsoft Edge sends instead of the default user agent for specific websites.
To display the list of user agent overrides that are currently applied:. The Microsoft Edge Canary and Dev channels don't currently receive user agent overrides. Use the Microsoft Edge Canary and Dev channels to reproduce issues on your website caused by the default Microsoft Edge user agent. Open a command prompt. For example, enter cmd in the Windows search text box and select the Command Prompt app. Skip to main content. This browser is no longer supported.
