How do I make /sdcard link point to external SD Card on Android 4.4.2? I've got a Samsung GT-I9505 phone with Google Edition Rom installed. As my phone comes with 16Gb internal storage, I bought a 32Gb microSD. However, the phone still uses emulated SD card to store all data.

I looked through the filesystem and found two places which might be of interest:  


  symlink: /sdcard -> /storage/emulated/legacy
  symlink: /storage/sdcard0 -> /storage/emulated/legacy


My actual SD card, however, is at /storage/extSdCard

As far as I get it, apps use the first symlink to access SD card. I tried to use terminal emulator with root permissions to make these symlinks point to the right direction, however, it says that the filesystem is read-only.

This is where I got stuck and ask for your help to make my phone use the right SD card.
As far as I know, you can change this by editing /system/etc/vold.fstab, but if it doesn't have what you need, you might have to tamper with init.rc inside boot.img.

I'm not sure if what you're aiming to do is safe though, what with the recent switch to fuse sdcards.
