A:AnswerIOGEAR says: Thank you for choosing IOGEAR. The GFR3C312 sill read most SD and Micro SD Cards. This card reader will work with most phones that have a USB C port . The Samsung J-7 has not been tested with this card reader . The J-7 would have to support OTG to work with this device. As the customer stated below you can copy what files are needed to the Micro SD card using this card reader and then place the card in your J-7. Once again thank you for choosing IOGEAR.
A:AnswerYes you can! I use Iphone 12 pro, I had to download an app 'i-flashdevice' to access sd card documents. This application helped me manage storage of the connected SD card and play songs from the card.
