Galaxy Tab 7.7: Make Apps write to external SD

By default, apps do not have the permission to write data onto the external SD card in the Samsung Galaxy Tab 7.7. However, there is a hack that lets you accomplish that. It requires you to have a rooted Tab though.

Ready? Here are the steps:


1. Using a root-enabled file manager, navigate to /system/etc/permissions and make sure you have mounted the file system r/w.
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 your Galaxy Tab.
