Re: need a primer on wifi direct
dave1812 & bencostello,
My wife & I have only had our androids for a few weeks, but like chevrolet.racing252, we've had no problems transferring files, gallery pics, S memo's, etc. with Wi-Fi Direct. We didn't know what we were doing, but it seemed to work great. However, I did notice that there's certain instances when the—"share via wifi direct"—is not in the 'Share via' menu list. I remember telling my wife that: there's no share via wifi direct in my 'Share via' list ! :-\. . . (in fact, I think it was whilst I was trying to send from the gallery, if I'm not mistaken), but then I noticed a big Wi-Fi icon next to the 'Share via' icon, in the same toolbar. Upon clicking it, and acknowledging that you indeed want to send your (whatever) via Wi-Fi Direct, it quickly dispatches it, and...BAM ! ...it's in the other Wi-Fi Direct enabled device.
Of course, you have to toggle the other Wi-Fi Direct enabled device to 'On', first.
Then, after your (whatever) is sent, a notification chimes and a notice about your Wi-Fi Direct transfer appears in the Notifications drop-down list.
Don't know if any of that may help you, but hopefully it, or someone else's advice will. You can also watch tutorial video's @ the Samsung and/or AT&T sites.
