+What I will do is modify the {{{/fstab.samsungskomer}}} to change the mount of the ext4 {{{/data}}} of the internal location {{{/dev/block/mmcblk0p25}}} to the second partition of the external SDCard {{{/dev/block/mmcblk1p2}}}. Technically speaking you do not even need to root your device, but by flashing firmware you will need to do some pretty advanced stuff.

+== Format SD Card ==
+Format 32GB class 10 or higher SDcard with two partitions:

+1. 20GB vfat partition, this will serve as the normal extSdCard
+2. 12GB ext4 partition, this will serve as the new /data partition (make sure it is the second and last partition)
