A few days ago leaked the APK of the new Samsung Application to talk to your smartphone, the long awaited application S-Voice (The "Siri" of the Samsung) that comes in Galaxy S3. With the APK released could use it openly in our devices.
Shortly after the release of the APK the Samsung began a blockade of the application to work only on Galaxy S3 smartphones.
In this scenario, Samsung pronounced saying that the current version of S-Voice isn't definitive and that it doesn't want its users find the application that is still in testing phase (beta).
Samsung says that during the launch of the Galaxy S3 users can test the service, but the question is if the Samsung will provide the S-Voice service to other devices such as Galaxy S, Galaxy SII, Galaxy Note, Nexus S, even though some may not enjoy it due to hardware limitation.
By the effort of the XDA-Developers, the new Samsung S-Voice application can be downloaded by circumventing the restrictions of the Samsung, although not the final version, you can use it.
