Every time I plug my Samsung tablet into my iMac, I have to click "Allow" in a dialog that says "Allow access to tablet data?". Is there a way to make connection automatic?
maybe have a look at the usb settings in developer options and change it from charge only to transfer files, I don't know if maybe it would make a difference to also enable usb debugging in developer options as well
Is there Bixby on this tablet? If so, is it possible to set a Bixby Routine to do this for you? Just a thought. It may not be possible, but I thought I would mention it.
I've been through every setting and sub-setting and I can find no reference to USB, Developer Options, File Transfers or Bixby. I'm using the Android File Transfer app to effect transfers. Might there be a better one?
