Frequently Asked Questions (FAQ) for version 3

What are the main changes in version 3.0?

• The core technology now combine code obfuscation and encryptions, enhancing resistance against static and dynamic analysis attempts on the security module.

• Improved/replaced certain encryption/decryption features that affected app stability and initial loading performance, resolving ANR issues during app initialization.

• Parallelized and optimized the security application process, greatly improving the speed for large apps and under heavy user loads.

What are the differences between the previous 2.x.x.x version and 3.0?

• Previous Dex encryption options have been changed to obfuscation options, and related CLI tool options have also been updated.

• Dex obfuscation in 3.0 is not symbol obfuscation, so it is strongly recommended to use Proguard/R8 for symbol obfuscation before applying security.

• Changed Hacking threat alert’s design and messages. Below attached images are comparison of alert when detected Developer mode in device.

Why should I upgrade to version 3.0?

• Performance improvements in the security module have greatly reduced app launch delays. ANR/crash issues during app initialization have also been addressed. This enhances end-user’s experience.

• Enhanced anti-reverse engineering technology provides stronger defense against analysis and bypass attempts of security logic.

Has there been any change in app performance?

• App initialization performance has been greatly improved compared to previous versions.

• Memory usage during app runtime is slightly improved.

• CPU usage during app runtime is slightly increased.( We are working on this to improve in next update )

• The app size has slightly increased before and after applying app security. The increase varies by app, but for apps under 100MB, an increase of 10MB to 20MB is typical.

Will existing data or settings be preserved during the upgrade?

• Data will be preserved as before.

• For security settings, except for removed/replaced features, you can use the same settings and CLI tools as before. New options will use default values if not configured.

How do I upgrade to version 3.0?

• You can select service version 3.0.0.1 in the DoveRunner Mobile App Security Console.

• If using the CLI tool, specify "latest" or "3.0" in the service_version variable to apply version 3.0.
  You can find newly added sealing configuration for CLI tool at the Developer document.

Are there any features not supported in version 3.0?

1. ReactNative protection is not supported. New features are being developed to support ReactNative regardless of version. (Other hybrid platforms will have the same level of security as before when selecting 3.0.0.1 in the Native version.)
