swap internal sd card to external storage I wanna make my external sd my internal one without having the need to use an app. So Instead of having 8GB of internal storage I want to have 64GB (taken from the micro sd card). It worked on my previous phone Gt-i8530 if I changed the vold file to this:

# internal sdcard
{
ums_sys_path = /sys/class/android_usb/f_mass_storage/lun0/file
secure_format = enable
discard = enable
}
dev_mount sdcard1 /storage/extSdCard 8 /devices/sdi2/mmc_host/mmc0/mmc0 encryptable_nonremovable

# external sdcard
{
ums_sys_path = /sys/class/android_usb/f_mass_storage/lun1/file
supported_exfat = disable
android_secure_containers = enable
}
dev_mount sdcard /storage/sdcard0 auto /devices/sdi0/mmc_host/mmc1/mmc1


So now I want to do that same thing on my new phone SM-G3858. But I only have in vold:

#storage_struct = series, "/mnt/sdcard/extStorages"
#storage_struct = parallel
{
supported_exfat = yes
}
dev_mount sdcard /storage/extSdCard auto /devices/platform/sdhci-pxav3.0/mmc_host/mmc1


Now what do I need to change or add here to swap it as on the previous phone? I´m a bit confused that a) it right away says extsdcard here and b) that there is only one command line instead of 2 . I guess the reason is the #storage structure?

And suggestions please?
Unless it's important to you that the storage volumes are swapped, in Android Marshmallow the sd-card storage can be added to your internal storage with Adaptable storage.

Adaptable storage "enables a user to set up his SD card as internal storage, and store applications, their data, and media on an adopted SD card." –Source

Note: A high-speed card (UHS-1) is highly recommended, since you'll be experiencing lag and slow application speed with slower/older cards.

To use the feature: 


Turn off your phone
Insert the SD-card
Turn on your phone
Choose "use sd-card as Internal Storage" (When provided with the option - it should appear as a notification)


Android will then set up the card for internal use.
This will make Android show your sd-card as part of the internal storage and be used as such. The proces also encrypts the card, so your data is safe.

Note: When the card is set up as internal storage, you won't be able to use the card as a normal sd-card, fx. plugging it out and into your computer to copy files won't work. To use the sd-card like this again at a later point, you'll have to reformat the card.
