Have you worked with physical devices or emulators for mobile devices?

In working with mobile devices, I used both physical devices and emulators. Physical devices were used to verify the real behavior of the application on different models and OS versions, which is important for identifying specific bugs.

Emulators were used for quick testing and automation, as they allow for fast launching of different configurations without the need to have multiple physical devices.

For example, Android emulators from Android Studio were used for Android, and Xcode simulators for iOS. Automation testing often involved tools like Appium, which support working with both emulators and real devices.
