Requirement : Rooted Samsung device.
This is simple application which activates some hidden features by samsung on regional basis.
Note that this application itself doesn't have any own features but just adds required codes to others.xml/features.xml file on your system. Features works or not is totally depends on your device and firmware. we can't do anything in this case.
Here is free version for XDA users if you want to test first.
