Fix Xiaomi Redmi Note 3 can’t write issue with Micro SD card

To solve this problem, we will need root permissions and file manager with root-access (X-plore File Manager, ES File Explorer or any another).

  1. Open the file manager
  2. In the /system/etc/permissions find the “platform.xml” file
  3. Open this file in the file manager text editor.

Find this part:

<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
</permission>

Add new line <group gid=”media_rw” />, so it look like this:

<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />
<group gid="sdcard_rw" />
<group gid="media_rw" />
</permission>
