Why can't I download files to the micro SD card on my android smart phone (Android 4.4.X) using the WI FI SD APP? Category : Setup / Operation In Android version 4.4 or later, the Third-Party software has no permission to access files in external micro SD cards. Please change the storage path to the phone's internal space. Is the answer helpful? Related Why can't my digital camera use a higher capacity flash card? Why do I see lines on the right of photos after I downloaded photos using the WI-FI SD app? Why do I need to format the memory card before using it for the first time?
