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 much content can you store in a card ? Why is the actual storage capacity of the product slightly less than the volume specified on the product's package? How do I restore to the default settings after updating the Wi-Fi SD firmware to v1.7? Technical Support If the answer can't help you, you can contact the Tech Support Department Get Started
