A device emulator is a software program that allows a computer to mimic another device's functions, enabling the host system to run programs designed for the guest system. This is commonly used by developers to test app functionality by simulating a mobile device's look and behavior on a desktop or laptop. While emulators help in app development and testing, they can also be misused by fraudsters to exploit ad spend.
Device emulators are used for automation, unit testing, and debugging, but for the most robust testing, it's best to run your application on an actual mobile device.
Real device testing involves using physical devices to test web, hybrid, and native applications, ensuring they work smoothly in real-world conditions. For example, while an emulator can simulate app performance, it can't replicate interruptions like phone calls or battery issues, which real device testing can.
Real devices provide accurate results but are more expensive due to the need for multiple devices and frequent updates. In contrast, emulators are cost-effective and convenient but may miss certain performance issues that only appear on real hardware.
Device emulators are essential tools for app developers, allowing them to test their apps on various devices and operating systems without needing to purchase physical devices.
For example, developers can test an app on multiple iOS and Android versions across different devices like iPhones and Samsungs, saving time and money. Emulators help identify necessary changes and improve the app's functionality and user experience. This ensures the app works well on different platforms and manufacturers. However, while emulators are beneficial for development, they can also be misused for mobile fraud schemes.
Fraudsters misuse device emulators by programming them to mimic real user actions, such as clicking on ads, installing apps, and using in-app features, which creates fake users. This fraudulent activity wastes marketing budgets and redirects ad spend to the fraudsters.
For example, emulators can repeatedly download apps to make it look like many people are installing and using them. This allows fraudsters to steal money meant for genuine advertising. These operations often use data centers and VPNs to hide their true location, but by identifying and blocking these fake activities, marketers can protect their budgets.
