Samsung India has pushed out a new firmware update for the Galaxy S4 (I9500). The update does not bump the Android Lollipop to the latest version but the 327MB-odd update seems to bring a lot of changes under the hood. Although most changes are unknown in the update, Samsung has upgraded KNOX v1 to 2.0.
Furthermore, the new update brings back the mute option that went missing in the phone after the Android Lollipop update. Since Android Lollipop, users had to activate the ‘Always Interrupt’ option to mute the phone.
