According to the latest stats from the Google Developer portal Android 4.4 KitKat currently occupies 13.6% share in the overall distribution of different versions of the operating system. It’s really unsatisfactory given the fact that it’s has been almost seven months since KitKat was first released. While KitKat is known for better and faster performance that the older Jelly Bean, the former is also known for taking away some good features that we used to enjoy on the latter.

With the KitKat update, Google brought a not-so-pleasant thing by revoking the write capability to external SD card by app on an Android device. You must have seen the Move to SD card option under individual app settings on Jelly Bean. It simply means that KitKat does not allow apps to write/move data on the micro SD cards on devices that support expandable storage. If you install too many apps, your phone’s internal storage might fall short as all app data will be stored to it.

Actually, Google removed the write access to the external SD card by apps deliberately for security reasons. Google made this move to stops apps from dumping files everywhere on the card. On Kitkat, all 3rd-party apps can only write to files and folders that they have created or have taken ownership of.

As you know, Android is a world of possibilities. If you have have obtained root access on your device, you might obtain a solution for almost all such issues. The Play Store already has a couple of good apps for fixing write access to extSD card by 3rd-party apps.
