Perhaps this is what Samsung meant when it said it would addressing GS4 storage capacity concerns through "software optimization." Samsung is starting to roll out an update to both the international and U.S. versions of the Galaxy S4 that will allow users to move applications to an SD card. Previously, a user would need to root his or her device in order to do that. It also includes several other enhancements, including new camera firmware, an issue with ?smearing? while scrolling, HDR video support, a semi-transparent status bar, new settings icons and more.
The software is apparently already hitting Qualcomm-based Galaxy S4 devices but an update for Exynos-equipped devices is on the way, too. A quick check on our AT&T Galaxy S4, however, showed us that an update is currently not available. Perhaps it?s rolling out over time or needs carrier approval, first. My friend had the same issue with her S4 and this is what we found... Hope it helps !
