When I was trying the Wifi direct transfer on the TF300, I can't found the transfer icon of wifi direct, the choose icon only ' blue tooth, gmail, webstorage...' that without wifi direct.
I really don't know how to send the file from TF300 to S2 without the wifi direct icon.
conversely, S2 send the file to TF300, the status was holding in transfer, after they recognized.
I sent an email asking the wifi problem to Asus, but they replied that the problem transfer to other department already, and give me notice when future information'. The email over 10 days, I don't believe they have future information in shortly.
I also used an USB to linking both S2 and TF300, but TF300 seems can't recognize the S2, not any device was found.
Now, I only through the PC to make them communication which is TF300, S2 and PC linking together, then using the PC control file transfer. But it is not convenience.
