Holy cow... can this get any more stupider? Is stupider really even a word....? But I have to admit, if Samsung and Verizon get put in the same room.... it can become even More Stupiderier than ever before.

So, you turn on NFC on your Android device and Android Beam turns on. You back-to-back the phones (two S3s) and you tap the photo... And it doesn't work because S Beam is not turn on....

Wait... wait a second... you mean the actual native OS NFC file transfer protocol doesn't work so you have to use the manufacturers variant.... OK... WTF!!!! How many freakin' switches do I need to throw to perform what was designed to be simple tasks? I think it's easier to tap the Gmail Icon on top of the gallery and email the photo.

These guys can screw up a wet dream. No S Beam Widget either. Wonderful!!!

I dont think you can normally send media through nfc...more like small tidbits of info like google play links, url links, etc. Maybe its just me?

[EvilMonkey]

^ Of course you can. I send pics and videos to my wife's phone all the time.

That being said, I have no idea what the difference is between all the options. I mean, there's NFC, Android Beam, S Beam, Wi-Fi Direct, etc.

All I know is I have the NFC checkbox checked on both phones (and Wi-fi direct disabled) and it works fine. But then I get something about Wi-Fi direct a few minutes after using it (about it being inactive and disabling it). I assume when I tap the phones together, since NFC is on, it must activate Wi-Fi Direct....

But I don't know if I'm using S Beam or Android Beam or Wi-Fi direct when I transfer the stuff over. Beats me. Reading the descriptions for Android Beam vs. S Beam makes it sound like Android Beam can't send files....only browser pages, youtube videos, contacts, etc. Then if you use S Beam it says stuff about media files...

anyways, I have NFC, Android Beam, and S Beam all on, then Wi-Fi direct off and haven't had any issues sending things to her phone. I wonder if I could turn something off and save some battery or something.

OK. I have figured it out. Here is a primer. Following the primer, I will discuss some detail:

- Android Beam - the NFC communications standard for file transfer on devices that use the Android Operating System

- S Beam - the Samsung Variant of Android Beam

- WiFi Direct - yet another network/protocol alliance for direct device-to-device communication for file transfer

Now the details and examples:

* First you must turn on NFC for any "beaming" function.
* Next, if you are sharing a file (transfer) with another Android device that is NOT a Samsung Galaxy S3 phone (currently... will change in the future?) that supports Android Beam, you then turn on Android Beam on both devices and follow the "beaming" method.
* If you are sharing a file with another Samsung Galaxy S3 phone, then you turn on S Beam on both phones and follow the beaming method. The S3s support only S Beam between S3 devices -- one would expect that this will change with future Samsung devices.
* Complexity Warning - if both devices support WiFi Direct, the beaming function will want to transfer via WiFi direct... especially for larger file types - music, photos, videos, etc. It's more robust and a faster protocol. Beam is around the same speed as BlueTooth (another mechanism and another story).
* WiFi Direct is another methodology (it's not NFC based beaming) of allowing devices to both Share and Transfer files (files are files... documents, songs, music, contacts, videos, code, what have you...). The goal behind WiFi direct, as compared to DLNA or AllShare (Samsungs DLNA variant) is that devices that are WiFi Direct compliant need no WiFi Access Point host. AllShare does require a host WiFi network to work. In other words, the devices create an ad-hoc connection between each other using WPA2 security standards. You can be up on Mt. Everest and use a WiFi direct device (your S3) to create a WiFi host for other WiFi capable devices to share and transfer files. In short, WiFi direct is the bigger, faster, badder way of transfering and sharing files especially over distance (compared to NFC where the phones have to be touching to start and close together to finish the transfer). Devices using WiFi Direct need to be in WiFi proximity but not next to each other or touching. Finally, you can create a WiFi Direct Group and share files or transfer to multiple devices simultaneously as long as all are participating in the group with a secure access defined by the WiFi direct host. Again, all this is created Ad-hoc -- on demand at the time you desire to host the connections.

I think this pretty much sums it up. Got two S3s? S Beam. Got two Androids where one is not an S3? Android Beam. Got WiFi device(s) that want to either share or transfer files and the files are bigger and you don't need a quick hit but have a more robust need and/or don't have a WiFi network around? WiFi Direct.

If you have questions... let me see how this community can help.

I had a lot of problems with Android beam at first as well. Here is a blog post that goes into great detail how to use it and contrasts the differences between S Beam and Android Beam.

[n8ter#AC]

Too much bad info. It's simple.

Android Beam uses Blue tooth to transfer some data, like files. BT is slow because the only devices that have consistently be shipping with 3/4.0 + HS are Galaxy S devices. Everything else is EDR, which is still terribly slow.

Samsung solved thus by making their own version that uses WiFi Direct. The benefits are obvious and Android Beam between two GS3 devices is a waste of time.

More devices have WiFi Direct than the High Speed BT 3/4 profile. Google should have used that instead. Terrible decision on Google search part...

S Beam is necessary. It's what Google SHOULD have done from day 1.

why cant i simply have nfc feature in phone without Android beam and S Beam and just turn on NFC, phones placed back to back and I must be able to transfer any data???

[EngineersRule]

I tried to send a youtube link and pictures to my brothers note 2 with nfc and couldn't get it to work. We used a friends S3 and it works first try so it looks like nfc on my one x doesn't even work

I met a random person who noticed my phone she bumped me the new Adam Sandler movie in about 3 min. It was easy. And frikin awesome!

So can you troll. GFYS and DIAF IMO.

[Bilal Almuhandis]

if i enable S beam so will NFC automatically get enabled? or vice-versa

[Normand Beaudoin1]

Caution NFC may not function properly with the use of a 3rd party battery. To ensure functionality, only utilize the Samsung designed battery with Near Field Communication printed on the battery label.

Verizon just messes up the SIII. Best phone in the world (until S IV comes out). Verizon also has that annoying wifi notification. Can't it be on the top of the notification bar like other S3's. Samsung should some how stop carriers from adding bloatware like the iPhone. Not saying the iPhone is better but please remove the bloatware and carrier customizes like that NFC problem without rooting Samsung!!!
