Issue: The commercially purchased Watch 3 Pro New, when set to developer mode with developer options and hdc debugging enabled, can be recognized by the computer. However, when attempting to install an application package, it prompts with a message saying “Installing apps from unknown sources is not allowed.”
Solution: The partner is using Android Studio for development, and the application does not have an HW signature. They should use Deveco Studio to sign the application before pushing the package for installation.
