I was able to use an external card reader to upload files from my camera SD card to my Tab 4. It connected to the USB port. Can I do that with my Tab S3? I don't think the tablet recognizes the card reader.
More info: when I plug the card reader into the USB C port on my Galaxy Tab S3, I get a message that says "USB charging device. Tap for other USB options." When I tap, the next screen says Use USB to
○ Transfer files
○ Transfer images (says to select if transfer files doesn't work)
○Connect a MIDI device
○ Charge this phone
● Charge connected device
The last option is preselected. None of the other options can be selected. The card reader is only connected to the Tab S3 (SM-T820, Android 8.0.0), not to any other device or power source.
