Few days back Samsung launched Galaxy S4, it’s not yet available on the market yet but few guys extract the original dump of the Galaxy S4 and now you can download official Samsung Galaxy S4 Wallpapers, Ringtones and S Voice Apk.
SamMobile has obtained the set of ringtones, wallpapers along with the “S Voice” voice assistant app. S Voice works much the same as it does on any other Samsung device like galaxy S III, though it does seem to have major improvements.
You can use ringtones and wallpapers on any android device. As we all knows that Galaxy S4 uses the Nature UX and it seems like the Ringtones that were grabbed from the device are also using the Nature theme. I am sure your phone will breathe new life into your current setup by selecting one of the stock backgrounds.
Also I have personally installed S-Voice APK on Galaxy S3 and it appears that the app works fine. However, it has encountered some issues with AOSP based ROMs.
