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 My Laptop asks me to install the diver after I insert the SD/SDHC card into the internal card reader. Please provide me the driver. What should I do if I cannot delete or format my SD/SDHC card due to write protection? How much content can you store in a card ?
