Since The update of Android 4.3 jellybean to samsung Galaxy X4 There have been a noticeable error with many apps are failing to write to the external storage(Memory Card) ….
Since Google overlooked this error when rolling out the android upgrade on galaxy s4 , This has leaft many apps with the inability to write any data to the SD card..
The reason for this is a bit technical and is related to how Unix handles write permissions…There are some applications that needs to belong to a certain group before they can be able to write to the External storage , but unfortunately most apps havent been updated to adapt to this group , thereby causing a breakage when attempting to write to the External memory storage..
Fixing This Issue
Fixing this issue is not qiute difficult , but you need to be rooted before you can fix this….here’s what to do
>>Navigate into the system/etc/permissions folder, then edit the platform.xml file on the phone itself or copy it to the PC and edit it there.
>>Search for the line that says name=”android.permission.WRITE_EXTERNAL_STORAGE” >.. Under this should be the line .
>> Now, under ”< group gid=” sdcard_rw”> < /group>“ , add < group gi d =”media_rw”> < /group>, then save the file.
