Can you write to the sd card? Can but from MyFiles first - Samsung Galaxy S7 Questions and Answers

I cant write to the SD card.
I use ES File Explorer and I have created a folder on the SD using this app. I also permission and it is writeable.
So I ftp to that SD and it doesnt work.
I can ftp to my phone memory.
Then I copy the files to the SD and that doesnt work too.
I have format this SD using this phone.
Do you have this problem?

Having very similar issues but I thought that was because I encrypted my card. I can create a file in the root folder of the SD Card with Solid Explorer, but I can't delete it. The Samsung stock file manager works fine and can create/delete/move files anywhere, both internal and on SD.

I think those who get the phones early are beta testers for Samsung. We should be paid for reporting problems. I found 3 bugs already.

There is a half solution to this. I FTP using ES File Explorer to my phone storage, then move the files to the SD card storage using Samsung MyFiles.
It might be a ES File Explorer problem? Anyone knows?

Its marshmallow. Starting in 6.0 they changed the way sd cards have r/w access. Its a security thing. Dunno much about it. I say search it.

Hello. I was infromed about bug on my own project with sd card in S7 but I do not have one. Can you provide me some info so I can fix a bug in my app?
From your computer is you have adb, sdcard must be inserted.
Code:
adb shell ls /storage
or
From Terminal app on your device
Code:
ls /storage
Thank you in advance.

That's not going to work. GS7 is naming everyone's external SD card something different. For example, "D412-3A9A".
You have to go through the right APIv23 calls for prompting the user for SD card access.

[Q] Cannot transfer apps to microsd card option to move not showing

Hi, can anyone please help?
I have just purchased the Asus eee pad Transformer and it automatically updated to 3.1. I have put some apps on it through the android market.
I went to put some apps/photos etc onto the removable card to save some internal space but when I went into settings then to applications then to manage applications the option to 'move to sd' was not showing on any of the apps. can anyone tell me why and if possible how to rectify this.... what is the point in having a removable card and cant use it. Any replies would be much appreciated..... thanks Jayne
16GB is not enough space for your apps?
You dont need to move apps to SD card as all internal memory (about 16 or 32GB depending on which version you have) is used for applications.
removable sd can be used for for music, movies and any other 3rd party files..
16gb is more than enough for installing apps... (I think...)
there's no app2sd in honeycomb, this is different from what android 2.x does.
thanks for the replies,
I am not able to put pictures/music etc. on to sd card. how do you do it in case I am missing something
thanks
There are several ways to add to The removable SD card. You can get ES file explorer and transfer from SD Card ( internal mem) to Removable card or if you set up your system right use ES file explorer to transfer from your desktop/laptop to the Removable Memory. If you don't want to do that, just put the removable card in your computer , transfer music and photos to it and return it to the TF. I use a Tonido Plug ( small inexpensive ubuntu server) on my network to store everything, then just download or stream to TF via ES File Explorer.
Thanks for this answer, I was actually also asking myself this question.
I saw that app2sd exists on the android market so I guess it doesn't work on our transformer, right ?
there is also an issue I am facing : I downloaded a free application to measure the speed reading and writting of the new SD card I have installed. Whatever I try, the software always check the SDcard directory (so internal) but never the microsd I have installed.
I tried with another one and there is still the same problem. Is it a honeycomb restriction ?
Working with the microsd card seems very difficult (I am still a newbie that may explains why).
Indeed, most of apps only see your internal SD Card.
I've found something to work around the problem - you just have to edit/modify the vold.fstab file.
You can find it in /system/etc/.
Then replace this line:
dev_mount microsd /Removable/MicroSD auto /devices/platform/sdhci-tegra.2/mmc_host/mmc1
Click to expand...
Click to collapse
by this one:
dev_mount microsd /sdcard/_MicroSD auto /devices/platform/sdhci-tegra.2/mmc_host/mmc1
Click to expand...
Click to collapse
Reboot your TF01!
Now, your TF101 will mount the MicroSD in a directory from the internal SD Card '/system/sdcard/_MicroSD'. All your apps will see it...
PS: you can edit/modify this file with some apps like Root Explorer.
Need Permission
I tried to edit this file but came back with read only tag. I tried to change permissions but again came back read only system file. How do I change the read-only tag?
Found how to do it
I found how I could use adb to pull the file, edit in Notepad and then push it back. It worked.

[Q] Unable to write to SDCard, even with stock file manager in ICS

I've a P6800 with a SanDisk Ultra 32GB SD card.
Running android 4.0.4, build IMM76D.XXLQ2, NOT Rooted.
I'm unable to write to the SD card at all, not even with the stock file manager or other free file managers in the market.
Unable to copy files to the SDCard using data cable as well, copying to device memory works fine.
Only error I see is "Write operation failed" or something similar. Very little detail.
SDCard is formatted as FAT32, and I can write to it using a memory card reader.
Certain threads speaks of adding a new line in 'platform.xml' file, to add group 'media_rw' group for WRITE_EXTERNAL_STORAGE, but I have that group already in the platform.xml.
http://forum.xda-developers.com/showthread.php?t=1414214&page=3
Any idea on how to solve this?
your sdcard might be damage... do you have any other sd to test...

No Sir, I don't have a micro SD card. If it's damaged, would it be possible for me to write to it using a card reader?
be casual... just dont call me sir... XD hahaha
one of my card acting like that until i reformat it. save the files to your pc and reformat the card. dont do the quick format in windows... just try the normal format option.

How did you edit that file if you are not rooted. It has likely not updated. Check it! Also make sure there are no typing errors.
Make sure your system is in RW mode so the changes are saved. Let us know your outcome.

Failed to write to sdcard1 after ota kitkat

Has any one else lost the ability to write to their socketed sdcard since the 4.4.2?

Thats a "feature" of kitkat. Can't be changed unless you have root.
Seriously?
Yes, see here for fix(if your rooted):

It's a security issue. Before KK, the SD card was wide open to any other process to be able to request read/write to any directory and file, regardless of whether or not they created that file or directory.
Now, under KK, a program can create a file or folder in a "protected" area and only that program has the ability to modify the contents in that folder. It cannot modify other folders or files that it didn't create.
Time to move the podcasts. So my older shows that I worked hard to keep to keep the ext sdcard1 as a target, will have to be copied to sdcard0.too bad.thanks @iBolski
No wonder BeyondPod kept 'accidently' putting shows on SDcard0 for the last year. Even though I "pinned" it to SDcard1 in the advanced settings.
Even with the application that patches the /etc/permissions/platform.xml, I have found certain apps still do not work correctly. Dolphin Browser, for example, cannot switch to /storage/sdcard1. It keeps saying it can't find it and I need to ensure I don't have "USB Mode" enabled, which I don't even have as an option when connected to a PC.
I also have init.d installed on my machine and I had startup scripts that mounted various directories from my external to the internal SD card to "fool" the device so that apps that wouldn't save to the external but the internal would save across a mount. Well, that no longer works. For example, Amazon MP3 will not save downloaded music anywhere except to the internal sd card. I had my startup scripts mount an amazonmp3 directory on my external SD card to the internal amazonmp3 directory on the internal memory card. When I proceeded to download music, it didn't show up in the external directory. However, I noticed that the internal sd card's memory did decrease. I then unmounted the directory and saw that the Amazon MP3 app was ignoring the mount under KitKat and directory saved the files into the /storage/sdcard0/amazonmp3 directory, even though it was mounted to the directory on the external SD card. It did work under JB and ICS, but apparently, with KitKat, some apps will still write directly to the native directory on the internal SD card, ignoring the fact that I've mounted a different directory to it.
The stock Moto camera will write to the external SD card if you go and change the setting for it. However, the Google Camera does not give you any option to store your pictures anywhere except on the internal SD card memory. :crying:
Remember, apps can write to the external card, if you don't apply the "patch", but only to what is considered a protected are (the /storage/sdcard1/Android directory structure) and then, they can only write to a directory that the app created. They can read other directories, but they cannot modify them.

That's official explanation (bull****) as you described above with non stock camera. Basically KK made external storage almost useless. I found this nice description quite long time ago.

I know at this point, Root Explorer still works with it, after setting the correct permissions into the /etc/permissions/platform.xml file. That works for a lot of apps. The only one that I know that is currently broken is Dolphin browser. I cannot navigate to the /storage/sdcard1/ area anymore. It keeps telling me it can't find the file or directrory and that I should make sure the SD card is ready and USB Mass Storage (haven't seen this option since my Droid X2) is not on.
So definitely, Dolphin Browser is doing something differently that even the patch isn't working for it.
Problem is that without root user cannot edit platform.xml and even after that some applications refuse to write to sd card. Another example is OfficeSuite 7 Pro which I bought and now cannot edit file if it's needed. Workaround is to save to internal then overwrite to sd card.
Basically stock Android becoming more and more limited, harder and harder to get root... That's so bad that I wouldn't update to official kk in the case that my phone has locked bootloader.

SD Card not showing up to grant permissions

I recently picked up a Samsung EVO for my S7 and when I tried copying and pasting a file from my internal storage to the SD card it says "Please choose the root directory of the SD card to grant ES permissions to operate"
However, my SD card doesn't show up. Ive tried different file explorers and even reformatted the SD card but it still doesn't show up.
Resolved, completely my fault as I was using an XML file for Package disabler pro which had the external sd card disabled lol
Please tell me how did u resolved it

Old thread, but I just had the same problem.
The package that is disabled and that you have to RE-ENABLE:
"External Storage" - "com.android.externalstorage"
Took me a while to find it. Good luck! (Not sure why the Package Disabler dev never fixed this, annoying as hell.)

Read only µSD Card

Hello. I had a Note 4 (with Android 5.1.1) and my SD card worked well. In my S7, this card is read-only, which is quite annoying for Titanium Backup. I tested with 2 others cards, formatted by the S7 in exFat, and the issue is still there. Am i the only one ? Is there any software solution like SD Fix for Android 4 ?
Thanks.
+1 here as well.
Cant modify any files in sd storage nor sd card in my S7.
Help please.

From my understanding, The app being used should be updated by the developer to be able to use the android feature to ask for permission to access SD card for editing, deleting. Incase the app has not been uodated by the developer it will fail to access the sd card for writing. Once a new app is installed and run, it shall ask for permission to access, which should be granted. Atleast this is what has happened with me, but the apps which are not updated since few months back are not able to access the sd card.
