A new update has apparently hit the Sprint version of Galaxy S4 (SPH-L720). The update comes a month later compared to the I9505 update and brings in similar features such as Samsung Knox and and a new permission that allows moving apps to the sd card.The update is available over the air for unrooted users and weighs 357 MB. If you are more of a Custom ROM guy, than you will probably need to wait a few days until the first releases based on this firmware come out.Now with the new feature that allows users to move apps to the sd card, the storage issues with the S4 are not so serious anymore. The new update also brings in some new features such as a Smart Pause toggle in the notification bar, two apps: Briefing and SPDclient, and transparent status bar mode for custom wallpapers.Sprint is only one of the first carriers to bring this new update to the Galaxy S4, so we will be expecting other to follow their example very soon now.
