ExtSD Fix.apk doesn´t fix the issue on my Note 4, 910C

Hello Kadiremrah & Dr. Ketan,
I am also on the Note 4 910C-model, running Dr. Ketan´s ROM, but can´t manage to write on the sd-card. I tried Dr. Ketan´s "ExtSD Fix.apk", as well as the method below.
This is the setting how the platform.xml looks on my device:
<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="media_rw" />
</permission>
I followed the instructions neatly, no typo, rooted, etc. but to no avail. Many months ago I already applied the same SD-card-fix on my previous phone (LG G2) - at that time it worked perfectly.
Here is some further info that I gathered from Root Explorer . Maybe there is something not correct with those settings.
The owner of the "storage/extSdCard"-Folder is: Owner: 0 - root; Group 0 - root
The permissions of the "storage/extSdCard"-Folder are set to: 0771
The permissions for mnt/media_rw are set to: 0700
I tried to set the permissions for mnt/media_rw to 0744, which immediately after the change gets displayed on the Root Explorer properly. But after a reboot it automatically goes back to 0700.
Any ideas what could be wrong here?
I just noticed that in the Note 4, storage/external_SD is called storage/extSdCard instead. Could that be causing the problem?
Kadiremrah, it would be very interesting to compare those settings with your 910C-model.

Try other SD card bcoz ROM is already prefixed for ext SD writing

Spot on, Doc.
I tried another card, works perfectly. Back to the previous one - same problem.
Then I experimented with the mount/unmount-option in the settings. I have to confess I usually take out the card without un-mounting it first. Now I did it properly and voila. It works.
Another thing is that all my backupped apps (via Titanium) refer to storage/external_SD, since this was the way it was called on my previous phone (LG G2). But in the Note 4 the storage-place is called storage/extSdCard.
A number of my apps can´t find the new place. Of course I could just go into their settings and change the sd-card reference. But is there a way to rename the sd-card folder from extSdCard to external_SD? Root Explorer doesn´t let me.

Thanks Kadiremrah for the platform.xml printout. As suspected, it´s the same as on my device. The problem seems to have to do with the sd-card itself - not the software.

---

Just to keep you guys updated.
In fact, the mount/unmount didn´t turn out to help much after all.
But using another sd-card solved the problem.

I cant get this to work? im rooted, downloaded the apk, installs fine. but when i click it nothing happens. just grayed out for 2 secs and then nothing. waiting for supersu to ask for permission. but no such luck?
got a SM-N910F

---

Check supersu app log. If it was rejected then select to forget. Or Uninstall and reinstall app
Sent from my SM-N910G using xda premium

it actually took like 6minutes before the supersu asked for permission. trying to flash a new stock rom now. phone was acting up lately.. will give this a go with a fresh install and report back.
thanks..

---

You don't need to be rooted in order to write to the external SD. Most apps create a folder in external_sdAndroid/data/ whatever the app is that's writable.

---

Forgot to report back. Did a clean install and this worked beautifully.. Now titanium can write to the SD card. (problem was that xposed and s health was not friends.)

Does it include "your memory card was damaged" when i format my mmc it last like a day then it damage again. Will this solution works for my issue?
