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 How come I can't download photos to my iOS device's camera roll via the StoreJet Cloud, Wi-Fi SD and DrivePro app? Why do I need to format the memory card before using it for the first time? Why can't my digital camera use a higher capacity flash card? Technical Support If the answer can't help you, you can contact the Tech Support Department Get Started
