Android N - Sd card r/w access? - Samsung Galaxy S7 Edge Questions and Answers

Hi people. I was wondering if android 7.0 has write access restriction to external sd card as it was the case for marshmallow and lollipop. Anyone tested this please?

External Storage Access on Kitkat

On Android Kitkat,Third party application can not able to write on External Storage sdcard.
How to overcome this problem?
Is there any solution?
I heard Android 5.0 allows us to write.
Is this true?
You cannot overcome this problem

I believe the only possible way to WRITE to external storage on KitKat is to run as root.
To write to external storage with 3rd party application, the application has to run as ROOT permission.
And maybe, Android 5.0 Lollipop allow 3rd party application to write on external storage
Have a nice day!

Strange behavior whenever I do a external SD Card operation.

If I want to copy files, create a folder, save a picture on external SD, every time, some pop-ups like this appear, asking me to select the root of the SD. I can see this is a extra protection, but i want to know more. What kind of protection is it, how can it be controlled, disabled... because many times it actually cause problems.
What is weird (I haven't seen this before on other phones) is the structure of the storage folder. I have inside 4 folders:
emulated
sdcard0
sdcard1
usbotg
In "emulated" is a folder called "0" (zero) that seems to mirror everything that is in "sdcard0" folder.
Phone specs:
P8Lite ALE-L21 Rooted, converted to Dual SIM (B190)
Please see attached images for details of the popup.
it's there so the user can select the permission that an app has to the SD card.
For the weird structure... SDcard 0 is your phones intern memory sdcard 1 is you phones sd card
those other 2 are (and i think, i don't know for sure) just needed for android.
if you go to settings -> advaced-> memory in android 6.0 you can select the card as internal memory. this shoul take care of the permissions and should let memory be catogorized as one partition.

I should have mentioned: Android 5.0.1 (not 6)
And is it there a way to disable this feature? As I said, on many occasions it causes trouble by not allowing a operation to perform properly. I suspect this feature has its own bugs too.
Thanks.

actually it's the same.
it's not a bug it's a feature
in kitkat we had the problem of restriction for the sd card. google changed that into this mode.
where the user grants the permissions. you can disble that the same way as android 6.0
by setiing the default storage location to sd card
in android 5.1 its settings -> memory -> default storage-> sd

SD Card Write Access from 3rd party apps??

Has anyone been able to get write access to the SD card from 3rd party apps like FX File Manager? When I try to enable write support it loads the dialog to select to root of the sd card, I do that, and it goes right back to the start of the process. This is the 2nd app that does this. I have the SD card encrypted and am running on the original firmware.
Cheers

Android stopped this awhile ago, you have to use native file Explorer to write to sd

Never tried with that method, but I'd say if it's not working for you still...
Worked once the card was decrypted.
If you're rooted there is Marshmallowsd
Yup or just modify ther permissions file
If you used package disabler pro there is a package that gets disabled by default I've attached a screenshot of the correct one to re-enable
tried package disabler pro on my S7 (SMG930U) but that package was not disable by default.

Rooted S7E: No SD Card Write

I recently bought an S7E. I was a little disappointed that there was no full root for the thing, but understand the situation with the locked bootloader. So I went the engineering root route. All is well and good there other than I hate that I cannot seemingly install any kind of recovery and make a full backup of the phone. Nonetheless, I the reason I am posting is that I have an issue with writing to the SD card. I have formatted the card with no change. I tried using root explorer to change the ownership of the card with no change (says it can't because of no write permissions). I even tried the KitKat fix I think it was in that you modified the platform.xml file to get write permissions. I had to use ADB to do that though but it too still made no difference.
So I am kind of out of ideas here. I first noticed it trying to run Syncthing which I use to sync files across devices for work and, of course, I use the SD Card for that purpose. However, other apps are unable to write as well like ES File Explorer, Root Explorer and so on.
Does anyone have any solution to this? I am on T-Mobile if that makes a difference. Any help would be greatly appreciated. Thanks.
Just to see if any fresh eyes on this may have some clues or answers. Thanks.

Install Fx explore from playstore. Click 3dot menu select enable write access.select 3dot menu and again select show all storage then from side menu select memory card then select right symbol on the bottom, you are done.
Thank you for that Anik49. That will get me functional for the moment, but is there not a way to make it permanent? Syncthing is unable to write to the SD card and I have yet to find anything that would adjust the permissions for that specific app or that would more generally give write access to the SD card outside of the file explorer.

Without root you have to give app permission to write on sd card but not all app have the option but with root you can do this you need xposed framework install on your phone. Then install xinternal sd apk and give the app proper permission. It will enable all write access to the memory card.

Maybe you need to root your phone and then find an APP named "SDFix: KitKat Writable MicroSD". Tell me if it works or not
