After enjoying Samsung’s new S Voice service that had been pulled from the Galaxy SIII, users started to notice a network error appear often enough to assume that Samsung had blocked the service. If you were running into this issue and can’t live without S Voice on your phone, there are a couple of fixes out there for you to try.
The first is a new .apk file. Simply uninstall the old one and install this one instead. You may even be able to install this if you aren’t rooted.
If that doesn’t work, there is another method that involves editing your build.prop to trick Samsung’s servers. You can find those instructions at the source link below.
Cheers Adam and Joey!
