For those of you who don't know.Google implemented an SD card write restriction on 4.4.
After the 4.4.2 kit Kat update any app that doesn't come pre-installed on your phone, either by Google, Samsung, or your carrier, will lack write privileges to the external SD card. Third-party cameras and image editors won't be able to save photos. Music players like doubleTwist, whose developers have made a plea for its users to complain to phone manufacturers, can't sync music to your SD card. Those are just a few examples of how this affects KitKat users, but it applies to every single app that you install.
