What? The Galaxy S3 was the most bug riddled peice of junk I have ever used. It wasn't compatible with half the stuff I tried with it.
The iPhone has had virtually no compatability issues because all of it's accessories are specifically made for it instead of a billion other devices.
I also am not sure what is going on with the file transfer nonsense, that sounds like this company is a marketing front for Samsung and is trying to push their NFC nonsense.
NFC is the way to go at this point of time.
