OK, so I have a Nexus 7 and a Galaxy S3. Both have NFC and it is turned on for each. Android Beam is also enabled.
I pull up a video on the S3 and bring it close to the N7 and the S3 video screen shrinks and the "Touch to Beam" prompt appears, so I tap the S3 screen. Then an animated graphic appears and the message "Ready to send files via S beam. Separate devices". In the status line on top of the S3 there is a downloading symbol flashing.
Then I slowly seperate the devices till they lay side by side. The S3 status line no longer shows a download and it continues to play the video; the N7 shows the message "New tag collected" and under it it says "text/directsharevideo". The N7 screen is unresponsive unless I use the home key to exit.
I have no evidence of anything actually being transmitted between the devices.
What am I doing wrong?
p.s. I did search both Google and XDA. If anyone can suggest a better search string than the title, please do.
I think you need JB for transmitting videos/images via NFC and the S3 is only rocking ICS.
Thanks for the heads up
I believe its to do with the tech they use to transmit after the NFC handshake.
GS3 uses WiFi to transmit and N7 used bluetooth.
I dont believe they are compatible, they can use tags no problem, but GS3 can only use NFC with other phones using WiFi Direct tech.
Hope this helps
Android Beam was not designed to send large files (NFC transfer protocol itself is very slow)
This is why Samsung made S-Beam on their s3 (NFC + Wifi Direct) so you can transfer any files you want, the only issue is both devices need to have s-beam.

Android Beam, from Jelly Bean upwards, uses NFC to initiate a Bluetooth connection. It's now possible to transfer larger files with Android Beam, though not as quickly as S-beam.
if you want to connect from android device to android device for transmitting media, check this one:
https://play.google.com/store/apps/details?id=com.budius.WiFiShoot
this was developed by yours truly, and I developed it exactly because I noticed there was nothing out there for WiFi Direct
I tested it between Nexus 7, Galaxy Nexus, Asus TF300 and Galaxy SII (stock ICS) and all worked fine.
The most problematic of those were the Galaxy Nexus that now always want to connect, but between N7-GalaxySII was flawless.
At the moment the app just works for photo and video but I'll be expanding more, if you guys fancy helping spreading the word about it, I'm really looking forward to see the downloads explode on it.
Hi guys,
is anyone with interested in beta test my WiFi Direct app?
I started a new thread in the development section asking for Logcats if you're experiencing force close.
Also it's a cut down version of the .apk there to test part of the system.

any help will be great appreciated.
thanks.

I recently upgraded my Nexus 7 and saw this in the "What's New" section:
Share what’s on your phone on the big screen.
Android 4.2 allows devices to enable wireless display. You can share movies, YouTube videos, and anything that’s on your screen on an HDTV. Just connect a wireless display adapter to any HDMI-enabled TV to mirror what’s on your screen quickly and easily.

I immediately went to Amazon and looked for different "wireless display adapters" per the announcement above, but I'm totally in the dark to which are going to be compatible with the Nexus 7. Does anyone have a recommendation?
Also, will I be able to connect to my Wi-Fi and still have an internet connection? I'm assuming I will be able to and it's more like they're all networked together (Computer, Display Adapter, Nexus 7, etc.), correct?
Lastly, I don't believe I noticed a new app on my phone to facilitate the connection once the Wireless Display Adapter is purchased and connected; am I missing something?
Thanks in advance for all of your help, you guys are the best!

Thanks for the direction. Checked that thread out and found that Miracast is not compatible with N7, but is there any other hardware/software that would be?

The N7 currently does not support Miracast, and there is doubt it ever can since it does not support 802.11a.
ya gotta love it

I have scoured the internet for days and days trying to find the solution to not having hdmi capability and hopefully I'm on the right path. The wireless way sounds like it will be the only possibility so I was reading an article on engadget . Unfortunately I'm unable to post a link to it on here. But if you search nexus 7 WiFi media you will find the article I am referring to.
Any of you more intelligent people have any comments, sounds like a 100 dollar solution. Thanks

That's not screen mirroring. It's just DLNA/UPNP. And there are better and cheaper solutions. First look if your TV already supports DLNA/UPNP. If not, get yourself a raspberry pi and install raspbmc, openelec or any other distro that gives you XBMC. Then just enable it in the XBMC settings and get yourself a xbmc remote and a UPNP/DLNA app like bubbleupnp. That way you can even watch nearly any media you want on your big screen including avi(enable unsupportet mime types in bubbleupnp settings) and youtube videos(in the youtube app just press share and then share it via your xbmc remote).
But it is still no screen mirroring like miracast. I still have hope for miracast on the n7, since MIRACAST DOES NOT NEED 802.11a it is only optional for better performance in some situations.
And if that doesn't work, there is always the amazing open source community. Android Transporter just needs to be implemented into Cyanogenmod and given sound support and we don't need to wait for the big players to implement miracast on our n7.
Look at what asus has to say.

Is anyone else having issues receiving files, pictures, music etc...using S-BEAM/NFC? (I have both options selected)
I tried sending files from a GNII and a SIV to the N7.2 with no luck what so ever. When beaming the files to N7.2 I get a Play Store prompt and it eventually times out.
However sending files from the N7.2 I never have any issues.
Has anyone else experienced this?
S beam will have to be turned off when using the Galaxy s4 or S3. It works but you have to use regular NFC with devices that don't have s beam. If you are looking for something similar from Android to Android device try super beam. This application does the same thing similar to s beam.

I can't get my NFC to work at all. It is on in the settings but it won't recognize any NFC device when bumped (tried with old N7 and S4). I even used a reader app to read my credit card and it didn't even pick that up (which my GS4 did with the same app). So NFC seems to be the only thing wrong with mine. If there's a fix that doesn't require a return or sending it in, that would be great.
As stated... With any Samsung galaxy device s beam has to be turned off and NFC only turned on.

Thanks for responding!
I turned off S Beam on the GNII and I was still not able to send picture using just NFC. I tried with S-Beam off and also with Android Beam off. With Android Beam off, it was really a no go. With Android Beam on, it would attempt to send the file, but the N7.2 would go to the Play Store, the same way it would with S-Beam on.
I am going to get my coworks GS4 and turnoff S-Beam to see if its an issue with my GNII.

On the Nexus 7 (2013), the NFC sensor is in the middle of the "nexus", in the same place as the wireless charging spot. On the Nexus 7 (2012) the sensor was towards the top of the device around where the "nexus" was. I have found the NFC signal to be exceptionally strong on the Nexus 7 (2013).
NFC from HTC one
Hi, I can use the same MiFare tags on either device but for the life of me cant get any connection between my HTC one and the Nexus 7 (2013). Its bothering me since I know both transceivers work. Is there some incompatibility? Before anyone replies, I am not a moron and yes all NFC options are turned on. I tried BT on/off too. I rebooted etc. Anyone?
I just tried using my coworkers GSIV and I could send a file from the N7.2 witout any issues. The phone actually had S-Beam on when I sent a file from the N7.2
I asked her to turn off S-Beam and to send me a picture from the GSIV. No good, the picture would not send. We turned S-Beam on and tried to send a picture and the Play Store option popped up on the N7.2.
Could it be that I just have a bad unit? I don't not have any other NFC enabled devices besides Galaxies devices around me lol...so I don't have any other way to test it out.
Sending from the N7.2 is great...receiving has been a failure using the GSIV & GNII.
Android Beam is built into every Android 4.0+ device with NFC. However, as of Android 4.1+, it can send photos and videos to other devices, so long as both devices have Bluetooth in addition to NFC. Simply open a photo or video in the gallery, put the devices back-to-back, and follow the beam procedure.
S-Beam is a proprietary implementation of this on certain Samsung devices, which predates 4.1's photo/video sending capabilities, and uses Wi-Fi Direct. Since it is uncertain if S-Beam disrupts the function of the Bluetooth-based Android Beam photo/video sharing, and only offers a few extra file sharing features, I would recommend turning it off, unless you have compelling reason not to.

Thank for the tip. Once I was able to find the "G Spot" I was finally able to send pictures and apps from my GNII to the N7.2!!! Now I just need to try out my NFC chips!!
Whew...I'm happy that its not my phone or the tablet...just took a more precise and gentle touch lol :highfive:
I got a Galaxy Tab 4 for Christmas, bought from Amazon for $119.00. Chromecast and OK Google both seem to not be working and I've done some extensive trouble shooting.
With Chromecast, I have a Sony XBR850C with built in AndroidTV and the tablet makes a connection and then immediately ends when casting. I've tried it with the Chrome browser on my Mac and it works flawlessly so I'm ruling out the TV as the cause.
With OK Google it doesn't allow me to train the voice model, it just sits at "Listening" when it asks me day OK Google 3 times. If I chose "finish Later" it takes me to the Google Now screen, I type the mic button and it hears me fine. I've tried uninstalling the updates and everything else I found online that is supposed to help but nothing did.
That's two of Google's core services that won't work on the phone. Everything else seems to be copacetic but I need those two things to work. I got the tablet to serve as a "living room device." It's basically a remote for my entertainment system and home automation devices but I'm a cord cutter so sometimes I'll need to cast from it.
Any thoughts on why these two features won't work? Do they share a common function that could be defective? Maybe the hardware is bad? Orr maybe there's something I'm not doing right but I don't think that's it.
My tab 4's OK google doesn't work also. Sometimes it does, sometimes it doesn't. My chromecast is fine. If you are using a automation app and it is set to turn off WiFi once screen is off (for battery savings), that could end the connection. Sorry if I'm not of much help, I am still a great noob
So my YoCam camera arrived, and excited to receive my new kickstarter toy, I tried to connect it to my phone following the basic instructions.
Phone sees and connects to the device via wireless, but the app refuses to connect. However using other android phones will allow me to connect to the camera, using exactly the same process., so it does not appear at least at a basic level, an android or an app issue.
Just wondering if anyone has any suggestions, or can suggest some troubleshooting tools so i can get a better view of what is going on.
Thanks
Hi, Not that this helps: I have exactly the same but on a Samsung Note 3 running cyanogenmod 6.0.1. When connecting to my Samsung tab S2 with standard Android no problem.
Are you running a alternative rom on your phone or standard?
Edit: see also Faq at getyocam.com
It will be awesome if someone can mod Samsung Note 9 to display Dex UI wirelessly (i.e. using wifi mirroring technology).
Personally, I'm against it because the lag will just ruin the experience... But, well, experiencing it myself can change my opinion
Um OK.

I have the Microsoft wireless adapter (Miracast) that I use with my Surface Pro 3. I also occasionally use it with the Note 8, mostly for watching videos. The experience has been great and the lags are infrequent. Certainly not a dealbreaker.
I think it will indeed be cool if Dex can be done via Miracast. I use couple of Dex apps (Dex Max and Desktop Hub) and it will be interesting to find out what their developers think. Maybe it will be possible to add a toggle to the apps that trigger Dex mode instead of screen mirroring when the phone is connected via Miracast...
Great idea
I guess Samsung heard you. Read this article ->
https://www.androidpolice.com/2018/10/02/samsung-working-wireless-dex-connection-upcoming-devices/
Awesome! After 2 years, my post now became a reality with the recently announced Galaxy Note 20 ultra.
Wondering now if this feature can be brought to our old note 9/note 10 via software update or does this require a specific hardware?
What you think guys?
Would be very happy if it's a software thing and they give it to us with the OneUI 2.5 update (if we even get that first xd).

GOOD NEWS !!!
Well I don't how and when it came to our Galaxy Note 9 but the Wireless DEX function is indeed there !
I was just testing the mirroring function with my Galaxy Note 9 and a Amazon FireStick (should work the same with a Google Chromecast) connected onto a 24" monitor via Smart View, then by chance at the end I just pressed the Dex icon and the Dex desktop display just appeared on the monitor !!!
I still have a message telling the "connected TV" is not fully optimized for wireless Dex but it's still working.
Then, There is a second message saying we can use the Note 9 as a touchpad and it works !
I don't have a USB-C hub with me but I guess we could use a mouse and a keyboard as well...

Don't remember when it came either, but I've been using it flawlessly on my roku tv for streaming from sites. Still get hiccups with it occasionally after a period of time though. Reconnecting usually seems to fix them it seems.
