# Developer Mode detection \[Android devices only]

Android developer mode allows deeper system access and debugging capabilities that can bypass app security measures. Developer mode can enable settings that facilitate the installation of uncertified applications and the execution of potentially harmful code, posing significant risks to data integrity and app functionality. FreeRASP detects whether the developer mode is enabled.

**Warning:** This vulnerability is particularly critical on Android 12 and 13 devices with Developer Mode enabled. A local attacker with ADB shell access can execute arbitrary code within the context of any non-system app, granting them full access to the app’s private data files, AccountManager-stored credentials, and other privileged resources. This bypasses the Application Sandbox’s intended protections, which are designed to isolate app data even from device owners.

Below are code snippets demonstrating developer mode detection across various platforms:

```dart
// Android Developer mode detection
override fun onDevMode() {
    TODO("Not yet implemented")
}

// Flutter Developer mode detection
onDevMode: () => print("Developer mode detected")

// Cordova Developer mode detection
devMode: () => {
    // Place your reaction here
}

// React Native Developer mode detection
devMode: () => {
    // Place your reaction here
}

// Capacitor Developer mode detection
devMode: () => {
    // Place your reaction here
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.talsec.app/freerasp/freerasp/wiki/threat-detection/developer-mode-detection-android-devices-only.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
