Advantages and Disadvantages Compared to Real Devices

Advantages

  • Cost efficiency: No need to purchase multiple devices.
  • Flexibility: Easy testing across different OS versions and device sizes.
  • Accessibility: Accessible from anywhere, especially with cloud-based services.

Disadvantages

  • Performance differences: Since they are not real devices, performance may differ.
  • Hardware-dependent features: Certain device-specific features such as sensors or camera functions cannot be fully replicated.
  • Network connectivity: It is difficult to perfectly simulate real-device network environments.

Conclusion

Smartphone simulators enable testing across a wide variety of devices and operating systems, improving development efficiency. However, before final release, it is recommended to also conduct testing on real devices. This helps ensure a more realistic user experience and improves overall app quality.
