I'm afraid this didn't work for me. I'm a bit new to working with an android device, but I have rooted the unit, and then acquired root explorerer, and then carefully edited the xml file noted. I rebooted and still cannot write to the extSD.

When I went back into the xml file, I noted that in place of two "group" tags (including the one I added for "media_rw"), only the one I added was in the permissions group noted. The one that was there when I edited is now gone. Even root explorer was not able to test create a new folder on the extSD.

Any suggestions?

CORRECTION: I can now navigate to the extSD and create folders via root explorer. But so far, other file managers (beyond the systems default) do not seem able to do so. Strange (to me). This also means I cannot copy and paste files either except through root explorer (which is sort of unfriendly to this newb vs. other file managers).
[Samsung Galaxy Tab Plus] zetajunkie:
My solution was to use a different text editor than stock (used "Text Edit," free through market) after using Root Explorer to set the folder to r/w (read/write). I had no luck using the stock editor...
[Samsung Galaxy Tab Plus] KChauJen:
Following the instruction, I can write to the External-SD card with Root Explorer, but if you reboot your table, whatever in there would be gone...

Does it happens to You?

Thanks
[Samsung Galaxy Tab Plus] StingerDog:
It does not.

I almost forgot this important step when I edited the file:

"The simple solution, if you're rooted, is as follows:

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 tablet."

Check to make sure you are saving the edit before you reboot.
[Samsung Galaxy Tab Plus] KChauJen:
Oh yeah!!! of course, if it doesn't, then it can't be created on the new files or folder in external storage.

Double check again, created the new text file on the root of "extStorages", then reboot.... result: File is gone

FYI
[Samsung Galaxy Tab Plus] garyd9:
I'll write a script to make this change to the perms file sometime this weekend (something that can be installed from recovery.) Using sed, I should be able to make the change "in-place" instead of completely overwriting the existing file. That'll ensure no breakage.
[Samsung Galaxy Tab Plus] KChauJen:
Thank You very much, garyd9. At that moment, whatever related to development on this tablet would be on your hand, Bro, and we are still waiting for the cooked rom... Hope it should be on your project.

Thanks again.

I'm also facing the same problem as KChauJen, where I have successfully made the changes to permissions.xml, tested it by creating a folder in the ext sdcard. However upon reboot, the permission is reset back (i.e. <group gid="media_rw" /> is removed).

I've tested it with the fix permission script and the permission is still reverted back
[Samsung Galaxy Tab Plus] garyd9:
Which model 7+ are you using? Is it from a phone carrier? Are you rooted (and if so, does 'root' stay intact after a reboot?)

Are you using any custom kernel's, recoveries, or anything like that?

Thanks and take care

Gary
[Samsung Galaxy Tab Plus] stelarinc:
I'm using GT-P6200, bought from phone carrier SingTel.

I've performed root following the steps here.

I believe it is still rooted after a reboot, as I'm still able to grant superuser access to FileExpert to perform modification to permissions.xml.

Other than that, I'm not using custom kernels. I do have avast AV installed, however, it does not give any alerts when I make manual modification to the permissions.xml
[Samsung Galaxy Tab Plus] garyd9:
Can you please go into settings -> "About Device", and type here the "model number" shown, and the "build number" shown?

My reason for asking is that there are many different versions of the same tablet floating around (GT-P6200, GT-P6200L, GT-P6200N, SGH-T698, etc) all being called a "6200" when they are slightly different. I don't have any of the 6200 tablet's myself (I have a 6210), but someone else (who has the same tablet/build as you) might notice something.

As well, it may be helpful if you could check the time/date of the platform.xml file immediately before AND after you make the change, then reboot the tablet and check the time/date of the file again. Does the time/date revert to what it was before you made the change, or does it change to something else?

Finally, permissions/platform.xml is considered a security file (as changes to it could make your device easier for a virus to infect) so it's possible that your AV is, in fact, reverting it. I don't use avast, so I don't know if it is or isn't...

Take care

Gary
[Samsung Galaxy Tab Plus] stelarinc:
I've got it working now. I'm not really sure what did happen, as FileExpert cannot overwrite the permissions/platform.xml or ext sdcard any more, even though it has been granted superuser access.

Instead, I did the following:

1) I uninstalled avast

2) installed and used Root Browser Lite to change platform.xml

3) reboot

4) installed avast back

5) reboot

After 1st and 2nd reboot, I checked that I'm able to write to the external sd card.
[Samsung Galaxy Tab Plus] garyd9:
Glad its working for you now.

[Samsung Galaxy Tab Plus] lanwarrior:
I just got a GT 7+ (P6210) - US Version and after I rooted the GT, I can go to /mnt/sdcard/extStorages/SdCard and write to it. I.e. using Root Browser, I can create a file.

I don't have to do the steps mentioned above. Is the steps above make it so that Market application CAN use the SD Card to install their support files? I.e. some games requires large downloads and in my Thunderbolt, that download will automatically go to the SD Card.

This may be the wrong area but is this fix good for most tablets? I have the onda vi10 elite running ics 4.0.3 and most programs cant write or even see the sd card. Any suggestions?

[Samsung Galaxy Tab Plus] Zadeis:
Someone please correct me if I am mistaken but as far as I know apps can not be moved to the sd card in Honey Comb correct?

If so that is why that particular app is saying there isn't a card.

[Samsung Galaxy Tab Plus] swlaraut:
Dumb question, but how do you "make sure you have mounted the file system r/w'?
[Samsung Galaxy Tab Plus] djskarpia:
filesystem r/w

it means that when you use RootExplorer at top you find "change to R/W" and you have to select it... doing this you'll have the permission to write files into the internal storage...

by the way, i have a big problem and i hope you'll help me... I did the root, installed superuser,busy box and i used the script fix permission to change the external storages permissions... it Worked about 1 month ago... but now, i can't understand why, after i update something i think ( superuser,busy box or my app tune sync) when i use Tunesync that is an app that synchronize iTunes with my device it says "busy sd card" and this is why tune sync can't' write over the external sd card... do you know what is possible that happens? i tried to reinstall superuser, busy box and also tune sync and i tried to fix manually the entries on platform.xml and retried to use fix permission.zip at the startup safety mode... BUT NOTHING CHANGES... my platform.xml is ok, have the two entries media_rw and sdcard_rw ... why i can't write on the external sd card?

thanks in advance,

Thanks for this. Used it a while back, 2012.12.24 , for my Sony Xperia Tablet S SGPT123US/S with Android 4.0.3 Release3 (Rooted). Method really works.

External SD card read-only despite correct platform.xml

Hi,

I am having the same problem lately with my Samsung Galaxy S2 on stock Android 4.1.2.

No application except the Root Explorer can write on the external SD card.

Unfortunately, changing /system/etc/permissions/platform.xml is not a solution in my case, since the platform.xml already contained the entry <group gid="media_rw" /> in the WRITE_EXTERNAL_STORAGE section.

I do not know, what exactly caused this issue: I installed a new kernel Dorimanx 8.14, installed a new BusyBox (1.21.1) and moved some Apps to (internal) SD with Link2SD, which did not work correctly (the Apps disappeared).

It seems that /storage/extSdCard is always mounted read-only (in Root Explorer I have to mount it r/w first).

Does anyone have an idea, how /storage/extSdCard can be mounted r/w again?

Thanks in advance,

Stefan
[Samsung Galaxy Tab Plus] Stefan6183:
Ok, I fixed the issue:

- Mounted USB storage (external SD) in CWM

- Backed up all files from my external SD (except a strange folder named µATA, which could not be read at all)

- Formatted the external SD under Windows

- Copied back my files to the external SD

- Restarted Android

Now the external SD is mounted r/w. Also in Root Explorer I can see that the external SD is r/w and not r/o as before.

Thanks for the fix! Worked great on ,my AN10CG3. I am now able to write files using es file explorer and was unable to before. However, I still have a problem with the external SD that was not solved using this method. Like I said I have no problem writing to the external SD card now, I ,am however unable to delete files from my external SD using es file explorer. Is there another permission Ibmust add to the section modified or another section perhaps? I would be grateful for any help with this. Searching has came up with no results. Thanks in advance!!!!

Problem solved

Just Download Root Browser

And navigate to storage

then click and hold on sdcardx(external sd card x=0,1 depends on your phone i think, mostly sdcard0)

now click on permissions then tick write on others option

done.

You should be able to write on the sd card:)

I formatted my extsdcard with ext4, and now using linux I can't create directories in the root of sd card, I change permission in platform.xml, create the userinit.sh, set UID and GID to 1023, if I try use it as a mass storage in Windows I get message to format it, but changing to MTP I can do it, include in the root, the problem occurs just in Linux, any tip?

I have a Sprint Galaxy Note $ Running Stock og5 Rom Rooted via Beast Mode TWRP then Play update, then flashed to Plazma Kernel. I have modified the /etc/permissions/platfom.xml file to include Group Id media_rw in the write to external storage permission and mounted the /mnt/media_rw/estSDcard as r/w in the root explorer portion of ES File Manager and it seemed to work fine for as long as I can remember but now if I try to copy or paste or send something to /storage/extSDcard it is created asychrously and ends up in the LOST.dir folder after a simple unmount remount or reboot or SDcard pull. Other apps are having the same problems like app backup restore and Btitorrent and others when trying to write directly to extSDcard I even went ass far as adding sdcard_all to the aforementioned gid permission set. It seems like such an obvious thing that has been overlooked by develpoers of the rom. I can create masting folders "no asychronously' if I do so buy navigating to /mnt/media_rw/extSDcard rather than /storage/extSDcard and they'll last but not all programs will allow that directory in their settings. Furthermore ES download Manager won't function with either directory and will not allow their app backup file to be saved the /mnt directory. only /0 or /storage/extSDcard.

I have exhausted my abilities with this and have no answer also It seems to be a new problem, and I haven't done anything I can think of to cause this. Partition table is 55000mb Fat32 17009mb ext4 journal partition on the extSDcard. Any Ideas?

Below you can see The before and after of unmounting and remounting my sd card resulting in Populated Lost.dir and loss of created folders also you can see the way that all nav methods resultu in same permission set when checked with a root explorer "total Commander"
[Samsung Galaxy Tab Plus] alwright1980:
UPDATE!!!

wELL i DON'T KNOW WHY BUT REFORMATTING THE SD CARD TO A SINGLE FAT 32 VOLUME SOLVED THE LEAK. i FIRST TRIED AN ALTERNATE SD CARD WITH A SIMILAR PATITION TABLE (EXT2/FAT32) BUT HAD THE SAME PROBLEMS EXCEPT THE DATA WOULD SIMPLY BE GONE INSTEAD OF IN THE LOST.DIR FOLDER. i HAVE YET TO IMPLEMENT THIS TO MY PRIMARY USE SD CARD because of the fact that I have backups and files that I need on that card from before the leak. I anticipate the same results, fingers crossed.

If ANYONE has any incite into why the partition table set up as it was would affect the retention of data in this manner please let me know.

PLEASE PLEASE let me know

I have a Samsung S7 SM-G930F and having the same problems. Even though rooted many apps, like Titanium Backup can not use the card. I tried your manual changes, but it was not identical and the change I made did not work,. Fortunately I had made a backup of System in TWRP so recovered immediately. Any suggestions, please?
[Samsung Galaxy Tab Plus] saf4xdadev:
First, this thread is for kit Kat. Yeah, it's pretty old. Second, write permission to external sd card is basically enabled for all apps in Android 6 as long as the app is up to date for android 6. It's the apps fault at this point. Once the apps are updated to conform then they will be able too.

The first time you need to write to external sd in the given app, android system will pop up a dialog box and you will choose the folder, or root of the ext sd, you will give write permission too.

---------- Post added at 02:21 PM ---------- Previous post was at 01:43 PM ----------

I just found a way to get titanium backup to set backup directory to external sd card and it works on galaxy s7....tested.

Create a folder on external sd:

Android/data/com.keramidas.TitaniumBackup/

Then go and choose that folder as backup in TB preferences. It will look like you can't select folders on ext sd, but it will turn green when you get to that folder.

EDIT:

highaltitude explained the correct method of setting ext sd as backup location.

Open Titanium Backup, Menu, Preferences, Backup Folder Location, Storage provider and than hit DocumentProvider Storage and select your SD card.
[Samsung Galaxy Tab Plus] jonners59:
Thanks saf4xdadev

I appreciate the getting back to me. I do realise it's 4.4 and no issues with old. I have just handed in my S3, and still have the clan using them. Personally if it wasn't for the need to change due to the phone starting to fail and not get the spares I was after I would have continued with it. It is better than the 7, nothing a little HW sawp wouldn't have solved if S had wanted. :)

I appreciate you letting me post, this was the only group that had the same issue I had found on my S7 and seemed to be over coming the problem. The creating a folder for TB has not worked for me, and the same on the other apps. I have found an app that has helped to an extent "FolderMount", but it is still not 100%....

[Samsung Galaxy Tab Plus] jonners59:
Thanks saf4xdadev

But wouldn't get too focused on TB, it was just an example of many apps that have this problem. Since writing to this thread and as a result of following some of the links, that then led to other forums and sites and threads, etc. I now realise that this is a known issue. It started with 4.4 when Google added the security to external cards, and peeps then created a workaround by editing the /system/etc/permissions and adding an additional group definition for this permission...<group gid="media_rw" /> under WRITE_EXTERNAL_STORAGE . That worked and some apps came out that added the fix automatically. I have a couple on my phone since starting this thread.

What is different is that Google have taken this a step further and removed the WRITE_EXTERNAL_STORAGE so now none of these apps work, and all "older" apps that require this cmd also do not work as you have pointed out. Some have tried adding the WRITE_EXTERNAL_STORAGE to the file but upon reboot it is deleted. I have heard of one person who has added the line to a modified config and added it via TWRP and it worked. That is my next step.

Unless anyone has a better idea because this will brick the phone, though I do have an image of the syst in TWRP.

1. Favorites is now spelled correctly when set to US English in the dialer! (Can any UK English users confirm if "Favourites" still exists when using UK English?)

2. Disabling of Airplane mode now gives a pop-up confirmation.

3. Polar Office is updated.

4. The ICS theme elements in the dialer seem to have been removed. Back to standard TW.

Ha ha, favourites is the correct spelling here in the UK and favorites is the bad spelling.
[Galaxy S II General] donalgodon:
Well, yes, I should have said that Favorites is spelled correctly in US English, which is the version I use.

Is it incorrectly using the US Spelling when setting the default to UK English where it should then read "Favourites" as it did before in both?

Too bad, because if it is, the dialer surely has the option to change languages completely, because if I set my phone to use Spanish, everything changes correctly.

I just prefer US English. I have edited the OP to better reflect this.
