Android 4.3 external and internal sdcard I am new  in Android so please be gentle.
I have the problem, that my phone doesn't use the external sdcard and try to save everything on internal 2gb storage.

So I rooted the device and get a shell on my device.
then I checked the mount point and saw that the /dev/fuse is used everywhere 

   /dev/fuse /mnt/shell/emulated fuse rw,nosuid,nodev,relatime,user_id=1023,group_id=1023,default_permissions,allow_other 0 0
   /dev/fuse /storage/emulated/legacy fuse rw,nosuid,nodev,relatime,user_id=1023,group_id=1023,default_permissions,allow_other 0 0
   /dev/fuse /storage/emulated/0 fuse rw,nosuid,nodev,relatime,user_id=1023,group_id=1023,default_permissions,allow_other 0 0
   /dev/fuse /storage/emulated/0/Android/obb fuse rw,nosuid,nodev,relatime,user_id=1023,group_id=1023,default_permissions,allow_other 0 0

   /dev/block/vold/179:33 /storage/sdcard1 vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1015,fmask=0702,dmask=0702,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0


my idea is to change the mounts everywhere and change /dev/fuse to /dev/block/vold/179:33

is there any special program technically location in Android to edit and save the new mount points?
Thanks!!
Try the SDFix application (for KitKat Writable MicroSD) on Google Play, which simply adds a line to the platform.xml permissions file (at /system/etc/permissions) to allow writing on the extSDCard.
