In Android KitKat 4.4.X, HE It includes a patch that limits the use of micro-sd cards and does not allow write on the sd as before. To do this out this app that “fixes” or repairs that access to SD and restores lost compatibility.
This patch to enable the writing on the SD only be useful if:
– You have an external SD, like most other Samsung
– You have mobile rooteado
– Usas la rom stock o de fábrica original.
What makes SDFix is to modify the system etc permisssions plattform.xml then allow writing in your External SD.
Once the process is finished you have to restart the phone or android tablet.
No need to use alternatives to factory roms as cyanogenmod…etc..
