Tronsmart T428 - pulsante "move apps to SD Card" mancante

[insaponata]

Ciao,

Da qualche mese ho la Tronsmart T428 su cui hgo installato una ROM custom (non ricordo più da dove l'ho presa ma funziona bene e non voglio cambiarla).

Funziona tutto egregiamente, tanto che ho presto esaurito gli 8GB della memoria interna. Allora ho comprato una microSD sperando di poter spostare le app più grosse lì. Purtroppo però nel menù standard (Settings -> Apps -> [click on move-able app]) non compare il tasto "move to sd". Temo che possa essere un problema di mount della scheda SD. Usando il terminal emulatore, infatti vedo che questa viene montata in "/storage/sdcard1":

Da notare che la memoria interna è montata tramite "fuse" mentre la scheda SD no.
Se serve posso fare upload di "vold.fstab" e "init.rc".

Credo che sia possibile spostare le app con degli smandruppamenti tipo link simbolici o app come Link2SD e FolderMount... Ma vorrei poter rendere visibile il tasto standard "move to sd".

Secondo voi può essere un problema di modalità o posizione di mount ?
