Works fine on Galaxy S3!

Entry:
For once I have to say that the quality offered for the low price is just excellent.
The cable offers excellent opportunities to USB sticks to smartphones to use.
This is particularly useful for presentations or Office documents that you can edit again quickly.

Delivery:
The delivery went as usual Amazon technically very quickly.
The cable was shipped to a small air cushion packaging.

Use:
If you put a USB stick into the adapter, the USB stick is recognized as SD card.
This way you can with any file manager (I'm using the standard file manager from S3 / My Documents) to access the data.
So it's the Galaxy S3 no root access and also not paid program necessary.
