Android KitKat and SD card not playing nice (via Android Central):

Prior to Android 4.4 KitKat, applications — provided they had permission to access the SD card — could read and write to any area on removable storage, including the system folders like DCIM, Alarms, etc. That has all changed, and now third-party applications — as in ones you download from Google Play or elsewhere — can only write to files and folders that they have created or have taken ownership of.

Dan orang-orang pun “di iOS tidak ada kebebasan”.
