Google Play Edition Galaxy S4 owners should all be enjoying the latest version of Android by now. If there’s one little niggle with the GPE handsets, it’s that updates aren’t provided directly from Google, and that may be one reason to blame for the SD Card bug which has appeared after the latest Android 4.3 update.
Users have been reporting that apps are failing to write data to the handsets external storage card. The reason for this is that most apps haven’t been updated to work with a change in app group permissions related to writing to external storage. As this is a problem which really only affects this particular handset, I wouldn’t count on app developers fixing the issue themselves any time soon, and it could be a while before Samsung released a fix as well.
Fortunately, there is a temporary work around, but it involves messing around with a system file and you’ll have to have your handset rooted before you begin. If you’re in need of the fix, then follow the steps below.
Firstly, grab a file explorer app from the Play Store, like Root Explorer or ES File Explorer, so that you can access your system files. You’ll then need to locate the platform.xml file in the system/etc/permissions folder. Create a backup of the original file before you go any further, then either open this file up on your phone or copy it to your PC for editing.
Next up, scroll down until you find a row beginning name=”android.permission.WRITE_EXTERNAL_STORAGE” >, I believe this is the 71st line in the file. Once there, on a new line under ”<group gid=”sdcard_rw” />“, add <group gid=”media_rw” />, then save the file. Here’s a screenshot to show how the file should look after editing.
All done, now simply save the changes, or copy the file back to from your PC, and overwrite the original version. Reboot your phone and the fix will be applied.
It’s likely that this line was simply missed while Samsung was rushing to push Android 4.3 out the door. Hopefully, an official update to address this problem will arrive quickly, especially for those who don’t want to mess around with these sort of fixes.

I am suffering from this issue and now have over 7GB of maps on my phone’s internal storage that I had wanted to place on the external SD card. I am unwilling to root my phone and ask who has the authority, the capability or the duty to amend the file platform.xml to include the missing line?
Its a simple matter of rooting using CF Auto Root, then editing the platform.xml file as stated with root explorer. Once fixed, you may goto the super user file and completely and fully unroot the phone, should not take more than 10 mintues.
Thanks Andrew and I will check that out.
I am currently writing an updater script to flash in a custom recovery, possibly the stock 3e recovery. I will post link after some testing, that is if you are interested.
I am too new to Android to even recognize the meaning or significance of a “recovery”. At this point I just want to add the necessary line into file platform.xml with as few collateral changes as possible. I am about to take a trip during which I must rely on my Galaxy for mail, news and navigation and so I am delaying the phone surgery until after that.
I now know what is left for me to do. Getting my self the new Nexus 5 i’m looking forward to test Android 5.0 !
Have fun with not removable battery, and yet no expandable storage again.
I have a galaxy 2 and have the same problem but when I opened the file it has the correct lines Any idea what to do?
The problem discussed here is the loss of write access to external SD cards as the consequence of the removal of one line from an Android parameter file in the update to Android 4.3 that was delivered to the Google Play Edition of the Galaxy S4. In what way do you believe that you have the same problem?
I have S3 (Rogers Canadian version) and upgraded from 4.1.1 to 4.3 OTA. I had the same writing/creating folder/files issue to external card as well.
Problem solved (Don’t need to ROOT the device):
Backed up the files to PC and reformat the external SD card using the phone (Don’t use PC format). It seems going from 4.1.1 to 4.3, lots of issues and incompatible stuffs. After formatted using 4.3 OS, copied the files back, creating folder/files works again on the external SD card. Hope this help those having same issues that I had.
Whatever issue you had with your S3 and that was solved by reformatting your external card will not be related to the issue under
discussion here and which is confined to the Android 4.3 that Google distributed directly to their S4 Google Play Edition phones.
can not work boos. I’ve add a group gid = media_rw. I use a 64GB class 10 memory Kingstone. but if using a 16gb memory down to write and read. and not be able to save the photo to sdcard.
Just did this the other day on my LG G Pad 8.3 GPE and it worked great, thanks for this post
