If you’ve stumbled upon the Chrome flag chrome://flags/#enable-command-line-on-non-rooted-devices, chances are you’re not just a casual browser user. Maybe you’re a developer, a tester, or just a power user who wants more control over Chrome on your Android device—without going down the rabbit hole of rooting. Sound like you? Good. You’re in the right place.
In this guide, we’ll break down what this experimental Chrome flag actually does, why it matters, and how you can enable it to unlock advanced functionality—even on a non-rooted Android device.
What Is chrome://flags/#enable-command-line-on-non-rooted-devices?
Let’s start with the basics. This flag is part of Chrome’s collection of experimental features—aka Chrome Flags. Think of them as hidden settings Google lets you test out, kind of like beta superpowers.
Specifically, chrome://flags/#enable-command-line-on-non-rooted-devices is designed to allow the use of command-line arguments in Chrome on Android devices that haven’t been rooted. Normally, using command-line flags (like forcing dark mode, changing the user agent, or setting test environments) requires root access on Android. But this flag is like a cheat code—it opens up that same control without needing to root your device.
Why Would You Want to Use Chrome Command-Line Flags on Android?
Great question. Here’s why this matters:
- Testing Websites or Web Apps: Developers often need to simulate different environments or behaviors in Chrome for mobile testing.
- Automating Chrome for QA: Testers use command-line switches to automate browser behavior during testing.
- Advanced Configuration: From customizing user agents to tweaking rendering behavior, command-line flags give you options the basic settings menu doesn’t.
- Experimentation Without Root: You can explore powerful features without voiding warranties or risking system stability by rooting your phone.
In other words, if you’re into Android development, QA, or technical SEO testing, this flag is a serious productivity booster.

🛠️ How to Enable Command-Line on Non-Rooted Devices
Here’s the part you’ve been waiting for—a practical guide. While this flag looks simple, enabling it isn’t a one-click process.
1. Update to the Latest Version of Chrome
As of May 2025, Chrome is on version 135. Always use the latest version from the Play Store, because some flags come and go with updates.
2. Open Chrome and Navigate to the Flag
Open your Chrome browser on Android and type:
pgsqlCopyEditchrome://flags/#enable-command-line-on-non-rooted-devices
Hit Enter. You should land directly on the experimental flag.
3. Enable the Flag
Change the dropdown from Default to Enabled.
You’ll see a prompt to restart the browser. Tap that. Chrome will reboot with the flag enabled.
Now comes the interesting part.
How Do You Actually Use Command-Line Flags on Android (Without Root)?
Just enabling the flag isn’t enough—you need to pass command-line arguments to Chrome. That’s usually tricky on Android since you can’t launch apps with custom flags like you would on a desktop.
But developers have found a workaround:
Method: Using the Chrome Command-Line File
On Android, Chrome looks for a specific file to check if it should run with command-line arguments.
1. Create the File
Use ADB (Android Debug Bridge) to push a file called chrome-command-line to:
swiftCopyEdit/data/local/tmp/
You can do this from a terminal or command prompt:
bashCopyEditadb push chrome-command-line /data/local/tmp/
Note: You don’t need root access to write to
/data/local/tmp/, which makes this method ideal for non-rooted devices.
2. Edit the File
The contents should look like this:
arduinoCopyEdit_chrome --your-command-line-flags-here
Example:
nginxCopyEdit_chrome --disable-web-security --user-agent="CustomAgent"
Then, restart Chrome.
Tip: The
_chromeprefix is required—don’t skip it.
Useful Chrome Command-Line Flags for Android Developers
Not sure what flags to use? Here are some handy ones:
--disable-web-security: For testing cross-origin resources--user-agent="CustomAgent": Mimic different devices or browsers--enable-features=WebContentsForceDark: Force dark mode on all sites--autoplay-policy=no-user-gesture-required: Automatically play videos

What If It’s Not Working?
You’re not alone—many users on Stack Overflow and Android Stack Exchange report issues getting Chrome to respond to these flags, especially after newer Chrome updates.
Troubleshooting Tips:
- Check Permissions: Ensure the file has read permissions.
- Use Stable Channel: Some Canary or Beta versions may behave differently.
- Update ADB Tools: Outdated ADB can cause push or write errors.
- Flag Removed?: This is experimental territory—flags get removed or renamed often.
If nothing works, check the Chromium Issue Tracker for open bugs or deprecations related to this feature.
Is It Safe to Use This Flag?
Mostly, yes—but with asterisks.
Chrome flags are experimental for a reason. Enabling command-line access can expose your browser to security risks if misused. You’re essentially bypassing standard safety nets. If you’re not sure what a flag does, don’t enable it.
Also, this flag is primarily intended for developers and testers. For everyday users, it’s best to stick to Chrome’s standard settings.
Why Is This Flag Trending Among Developers?
There’s no featured snippet for this query yet, but interest in this flag is growing because of:
- Remote mobile testing and automation
- Increased demand for cross-platform QA tools
- Security-conscious devs avoiding root access
- Continuous updates to Chrome and Chromium tools
As Android development and browser-based mobile testing grow in complexity, tools like this become essential.
Final Thoughts: Should You Use chrome://flags/#enable-command-line-on-non-rooted-devices?
If you’re looking for powerful testing and development tools on Android without the risks of rooting, this flag is a game-changer. It’s not a beginner-friendly feature, but for those who know what they’re doing, it’s like unlocking a hidden door in Chrome.
Use it wisely. Test responsibly. And always keep backups before tweaking experimental settings.
