This is what S3 can do
The Samsung Galaxy S III has a very cool feature may not know about it called "USB On The Go" that allows you to hook up any USB device to the smartphone.
We have a Video that demonstrates just how much USB Host functionality has improved on the Samsung Galaxy S III by connecting the phone to a flash drive, an external hard disk drive, a wireless keyboard, PS3 controllers (natively supported!) and of course larger monitors, speakers and others.
