How to Fix external SD card write issue on Android 4.4 KitKat

Restoring full access to the external SD card

Method 1: Editing the permissions file manually

Make sure your phone is rooted. After that perform the following steps:

1. Using a root-enabled file manager (like ESFileExplorerPro_v1.0.4_ModNoAD ), navigate to /system/etc/permissions
2. Edit platform.xml and find the WRITE_EXTERNAL_STORAGE permission.
3. Add an additional group definition for this permission: <group gid=”media_rw” />
   
4. Save the changes to the file.
5. Restart the phone.

Preface

Android 4.4 KitKat brought in a lot of changes compared to its older 4.3 Jellybean update. And one of the most significant changes is how it handles storage data security.

Prior to Android 4.4 KitKat, applications, provided they had permission to access the external SD card, could read and write to any area on removable storage, including the system folders like DCIM, Alarms, etc. That has all changed, and now third-party applications, as in ones you download from Google Play or elsewhere can only write to files and folders that they have created or have taken ownership of.
Third-party apps are not allowed to get automatic permission to put files anywhere on a micro SD card. Instead, such files must go into a folder on the card where all their content from that app must go. A photo viewer, for example, would not be able to move or save images from elsewhere on a device to its folder. It would only be able to save thumbnails of photos from within the system, which would be the images used for the viewer.
Many users are facing issues with the new configuration because it drastically changes the way apps function. Most apps have become dysfunctional because they now lack the permissions to function properly. Moreover, once a third party app is deleted, its designated folder and contents are also deleted. However, the flip side is that various malware no longer has the ability to read and write through a device’s filesystem to steal data.

If you are annoyed by the external SD card policy change, and storage flexibility matters more to you than storage security, read on to know how to restore full access to the micro SD card.
