The screenshot below shows a Pixel 2 XL running Android 10 with Android System WebView 84.0.4147.125 installed.

<p>There is enough information in the user agent that sometimes only a few visitors to a website will be the same.
If the user agent is combined with another piece of non-unique identifying information, often it results in a unique fingerprint.

<p>There are several preset user agents that match common browsers and operating systems. For browser fingerprinting purposes, anything that is rare is easier to track.
If Privacy Browser becomes common and many people use <code>PrivacyBrowser/1.0</code> as their user agent, it will be a good choice for privacy.
Firefox or Chrome are the most common user agents, but they auto-update and their version numbers change so quickly that it is likely the user agents included in Privacy Browser
<p>Some websites <a href="https://www.stoutner.com/user-agent-problems/">do not function correctly</a> if they do not recognize the user agent.
Using domain settings to set the user agent to <strong>WebView Default</strong>, or another user agent that is commonly recognized, usually resolves the problem.
- Android’s WebView does not allow the user agent to be blank. If it is, WebView simply sends the default user agent to the server.</p>
