[MENTION=5749760]ggow[/MENTION] I have an old Galaxy S2 with Lineage 14.1 (7.1.2). This is the content of the fstab.smdk4210:

40AA-07D3 is the internal storage, 9016-4EF8 is the sdcard. Both are visible in ES File Explorer under the "local" tab. The storage part in settings shows sdcard0 (internal) and sdcard1 (sdcard, with remove icon).

I tried to edit the line

/devices/soc/11240000.mmc* auto auto defaults voldmanaged=sdcard1:auto,noemulatedsd

in /fstab.mtk8173 with the editor from es file explorer, but failed, after saving the file and a reboot it was as original.
