What's the Latest Version of Android User Agents?

Latest Android User Agent Strings (July 2026)

The tables above are pulled live from the TestMu AI (formerly LambdaTest) device cloud. The reference below is a snapshot of the default user agent string each major Android browser sends, last verified on July 17, 2026 — copy any string directly for testing, scraping, or debugging.

Almost every string in this table says “Android 10; K” even though Android 16 is current. That is Chrome’s User-Agent Reduction at work: starting with Chrome 110 (fully rolled out by May 2023), Chromium-based Android browsers freeze the platform to “Android 10”, replace the device model with the literal letter “K”, and zero out the minor version (so only the major version in Chrome/150.0.0.0 is real — minor versions have been zeroed since Chrome 101). Samsung Internet adopted the same reduced format in version 24, and Edge and Opera inherit it from Chromium — only their EdgA/ and OPR/ suffix tokens differ. Firefox is the exception: it reports your real Android version (for example “Android 16”) but never a device model.

This is part of Google’s Privacy Sandbox effort to reduce browser fingerprinting. If your site genuinely needs the device model or OS version, use User-Agent Client Hints (UA-CH) instead of parsing the frozen string: request the Sec-CH-UA-Model and Sec-CH-UA-Platform-Version headers via Accept-CH, or call navigator.userAgentData.getHighEntropyValues() in JavaScript.

Android User Agents with Real Device Tokens (Android 14, 13, 12)

Modern Chrome no longer reveals which phone a visitor is using, but plenty of real-world traffic still does: Android WebView (the in-app browser inside apps like Instagram and Facebook) sends the device model, firmware build, and a “wv” marker; Samsung Internet did so until version 23; and any Chrome build up to 109 used the classic full format. The verified examples below are useful when you need to simulate a specific device and Android version in tests. Note that WebView switches to the reduced “Android 10; K” format by default starting with Android 17.

User Agent Android – What You Need to Know

Understanding the user agent Android is crucial for optimizing your browsing, development, and testing experiences. Whether you’re a developer trying to debug an issue or just curious about what your browser is sending to websites, you’re in the right place.

Why is the User Agent Important on Android?

Knowing your user agent can help with:

• Website Optimization: Developers can serve the right content based on device type.
• Troubleshooting: Helps diagnose display issues or compatibility problems.
• Testing: QA testers and developers often need specific user agent strings to simulate different devices.

Can You Change the User Agent on Android?

Yes! Changing the user agent lets you trick websites into thinking you are on a different device or browser. You can:

• Use Developer Tools on Android Chrome.
• Install a user agent switcher app from the Google Play Store.
• Use browser extensions if supported by your browser.

What’s Next for Android User Agents?

With evolving privacy standards, Google is gradually moving towards reducing the amount of information exposed through user agents. Initiatives like User-Agent Client Hints are designed to provide more privacy while still allowing sites to tailor experiences appropriately.

Frequently Asked Questions About Android User Agents

What does AppleWebKit 537.36 mean on Android?

AppleWebKit/537.36 is a frozen compatibility token, not the browser's real engine version. 537.36 was the last WebKit build Chromium shipped before Google forked the Blink engine in 2013, and every Chromium-based Android browser (Chrome, Edge, Opera, Samsung Internet) still sends it — together with "KHTML, like Gecko" and "Safari/537.36" — so websites that check for WebKit keep working. Seeing it on Android simply means the browser is Chromium/Blink-based.

What is my user agent string on Android?

The quickest way to see it is the "What is my User Agent?" box on this page, which reads the exact string your Android browser is sending right now. You can also type chrome://version into Chrome's address bar and check the User Agent field. On modern Chrome (version 110 and later) expect the reduced string starting with "Mozilla/5.0 (Linux; Android 10; K)" — the "Android 10" and "K" placeholders appear no matter which device you actually own.

What is the default user agent for Google Chrome?

As of July 2026, Chrome 150 on Android phones sends: Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/150.0.0.0 Mobile Safari/537.36. Only the major version (150) changes between releases — the platform is frozen to "Android 10; K" and the minor version to .0.0.0 by Chrome's User-Agent Reduction. On Android tablets the "Mobile" token is dropped, and real device details are only available through User-Agent Client Hints (Sec-CH-UA headers).
