Welcome to this in-depth tutorial on how to crash an Android phone with a text message. Please note that the purpose of this article is purely educational, and I do not endorse or encourage any malicious activities. It’s important to understand the potential risks associated with such actions and always act responsibly when using technology.

Understanding the Vulnerability

Android phones are complex devices with various software components that can be Targeted by hackers. One such vulnerability is known as the “Stagefright” vulnerability, which allows an attacker to remotely execute arbitrary code on an Android device through a specially crafted MMS message.

Step 1: Crafting the Message

To begin, open your favorite text editor and create a new file. Save it with a .txt extension for simplicity. Now, let’s start crafting the message:

  • Step 1: Open angle brackets (<>) to start an HTML tag.
  • Step 2: Type “img src=” followed by a URL pointing to a large image.
  • Step 3: Close the HTML tag with a closing angle bracket (>). The complete tag should look like <img src="">.

The above steps will create an HTML image tag that references a large image hosted on a web server.

Sending the Message

Now that you have crafted the message, it’s time to send it to your Android device. There are several methods you can use:

  • Email: Compose an email from your computer and send it to your Android device’s email address.
  • Messaging App: Use a messaging app or service to send the message to your Android device’s phone number.
  • File Transfer: Transfer the text file containing the message to your Android device and open it using a text editor or messaging app.

Effects of the Message

If your Android device is vulnerable to the Stagefright vulnerability and you receive the crafted message, opening it may cause the device to crash or behave abnormally. This is due to the malicious code executed by the vulnerability.

Note: It’s essential to keep your Android device and associated apps up-to-date with the latest security patches. Manufacturers and developers regularly release updates that address vulnerabilities, including those related to Stagefright.


In this tutorial, we explored how an Android phone can be crashed with a text message using the Stagefright vulnerability. Remember that exploiting vulnerabilities is illegal and unethical unless you have proper authorization for security testing purposes. Always use technology responsibly and prioritize user safety and privacy.
