I have a Samsung Galaxy S2 and no applications can read or write to the external SD card - except the Root Browser. This happened a month or so ago after I installed a custom ROM (Alliance) and I have lived without access to the external SD card since.

Since then, an application has managed to create one folder on the card that is accessible to a regular file manager (such as ES File Explorer).

When I use my PC to access the SD card, all is fine and visible, so I have deduced that it must be something in the android config files. I have checked /system/etc/permissions/platform.xml and I have WRITE_EXTERNAL_STORAGE

<group gid="media_rw" /> <group gid="sdcard_rw" />


<group gid="media_rw" />

  • I should mention that I have tried different micro sd cards and the problem is exactly the same. – carbroker Mar 27 '13 at 21:37
  • Did you ever find the solution? – TimothyP Apr 20 '13 at 9:24
