Purchased for Samsung Galaxy Tab S7+. While charging and earphones work. The MicroSD and SD card reader works great. USB port - not sure. I need to spin up 1 drive. But others, it only causes the device to reboot. There must be an issue with the format or size of the placement. USB-C data port - not sure but doesn't seem to be working. I have tried with the USB charging cable connected and disconnected. Nothing happens in Device Manager on my computer. It looks like it's just loading. Had to modify the leather case for this so the clamps could stay to keep it steady. Haven't tested HDMI yet.
