I am using AllCast like I always have but my S9 is not rooted and my S6 was.

I have got this problem too. I have a Samsung notes 3, stock rom and would love to use vpn and screen mirroring for the exact same reason. As a matter of fact, this issue affects anything that uses wifi direct. VPN and wifi direct do not work together, they seem incompatible after the update to 4.4.2 kitkat. This seems a serious bug that has been very seldom discussed. Is it possible our devices have something unusual?
Vpn screen mirroring allshare cast miracast wifi direct are all terms associated with this issue.
Hi did you guys solved the problem. I too met with this issue after upgrading to kitkat. Am using note 8. Need some help from experts. Would like to watch uk programs on tv thru screen mirroring.
Is there any confirmed Android version this used to work. It's so important to me, I think I would even downgrade.
Of course it would be a lot better if there was a general solution to this problem. It seems that all trafic even the screen mirroring itself gets routed to the new address.

I had same problem when my s4 updated to 4.4.2 so I think 4.4.1 should work. Any ideas where I can find that version and change it on my phone as I used to use vpn and allshare cast together all the time?
VPN is point to point tunneling. Therefore, it is proper to close off all other IPC channels. It is functioning property.

I second that. First of all, it used to work just fine according to a couple of forum members.
Furthermore VPN is a VIRTUAL private network, making you appear, you had another IP adress to the outside world. In your local network, everything else should work.

Any update on this guys? A pain in the t*ts. Its effecting my s4 & s5 both 4.4.2 rooted. A rooted s3 on a lower FW works ok but i don't want to have to keep the s3 just for that. As others posted only fails after you connect to a VPN and I need it for the same reason as others i.e. different regions of netflix.
screen mirroring
Hello, any update regarding this issue?, any ideas if this is gonna be fixed on the 5.0 lollipop update? one last question is there an aosp rom out there for the 12.2 or note 8.0 or S5 that supports screen mirroring that i can try to fix this issue, to have vpn and screen mirroring on at the same time? thank you and sorry for my poor English.
Screen Mirroring + VPN isn't working since KitKat (was working fine with Jelly Bean) for all Samsung devices (as far as I know).
There is no solution for sure as downgrade (wasn't able to do so on Galaxy Note 10.1 2014) was reported as not fixing the issue (as issue seems to be in the Kernel).
VPN with Lollipop seems quite uncertain (add new feature to select which App should use VPN or not, but lot of complaints of people about VPN simply not working).
I'm crossing fingers and I hope someone will have good news soon.
So i had this problem until i downloaded the boxpn app and miracast shortcut app. You have to have an account with boxpn but it's only 38 for 12 months. So i turn on my Samsung tv, i have a galaxy s6. Open the miracast app then turn on the vpn and it works fine. Screen mirroring and vpn
I like to stream but I can not stream and use vpn when I use screen mirroring on my phone I have a Samsung Galaxy grand is there a solution
I have tried this effort using box VPN and Miracast at the same time. It didn't worked and disconnect from WiFi.
There is only one solution for this problem you can use USB cable screenmirroring and from this if you connect with vpn it will not disconnect for reference you can checkout youtube that how to use screen mirroring using USB . Hence problem solved enjoy
Just exclude Android System from your VPN connection if your VPN app the functionality of excluding selected apps.
I had this problem for years and just suddenly came up with this idea.

Cast tablet screen to Chromecast?

I have a client who has a new Tab Pro 10.1 and he wants to know how to stream the screen of his tablet to his TV or PC at his office to use for a demonstration and use kind of as a remote whiteboard. He saw someone doing it at a meeting he went to last week, but did not ask how they were doing it. I have searched all around and it looks like he has to be rooted to do it, but it seems unreliable and I don't want to have to fix or set this thing up every time he uses it. I am sure he wont mind rooting his tablet if it means he will be able to stream his screen. I was hoping Chromecast would be able to do it easily, but it looks like that is not a feature yet and it can only be done fairly reliably through Chrome on a computer.
Has anyone done this yet? What do you recommend?
He has a:
Tab Pro 10.1 (stock)
Intel Nuc running Windows 8.1 Pro 64 connected to the TV
Chromecast
Vizio 70" TV
Thanks in advance!

That looks like a wired setup. I should have been clear that it needs to be wireless.
Thank you though!

There is an app preinstalled on the Tab - Sidesync 3.0. Need to install the app on the pc also. I haven't used it but I think it does what you want via wifi.
The tablet support screen mirroring (settings -> connections). Works fine on my sony bravia
You can use Chromecast but it will be slow for that. Instead use Miracast (What Brendo is using). There are many Miracast adapters if your TV doesn't have this capability.

The screen mirroring function will work with a Galaxy Tab pro 8.4 and a w605b Bravia TV?
Thank you!

It should. I have a bravia
On my S5 there is an option in the Chromecast app which allows casting. On my Galaxy Tab Pro 8.4, there is no option. I have tested both my S5 and Tab Pro 8.4 with Chromecast. Individual apps, like Youtube and Netflix cast fine, but the Tab Pro won't give me the option to cast the tablet's screen. If you have a Samsung "Screen Mirroring" compatible smart TV it might work (I don't).
On a side note. . . Although I know your client wants wireless, my old Samsung HDMI adapter for my S3 works with both my S5 and Tab Pro 8.4. The Samsung WI-FI All-Share Cast Hub, Wireless HDMI Display Adapter (can't remember the name) might work if you have that plugged into the video source. I didn't purchase it, so I can't test it.
I just recently bought a Chromecast and Tab Pro 8.4. I've been experimenting the last few days.
Basically, casting to Chromecast is going to be limited to apps with built-in Chromecast support. The only way I was able to do screen mirroring was through my WDTV Live set top box. Like Weo said above, you will need a TV with screen mirroring capability. My friend has a Samsung smart tv that he uses screen mirroring all the time.
Here's a nicely put together FAQ about Chromecast: http://forum.xda-developers.com/showthread.php?t=2563143
I think the only way to do screen mirroring to Chromecast is to root your device and install a hack: http://forum.xda-developers.com/har...experimental-enable-mirroring-device-t2812193

[Q] [SM-T805] Can't enable screen mirroring

Hello, so I've just bought the 10"5 Tab S and I can't enable screen mirroring.
My TV is a Sony KDL-40R470B, I can enable the screen mirroring just fine with Galaxy Note 3, but not the Tab S.
Any idea how I could solve this ?
And, this spanking new Tab S 10.5 doesn't even support Chromecast Screen Mirroring either! Come-on Samsung!!!
I was only successful wireless screen mirroring to an old Samsung miracast device. So, other than using an HDMI adapter tethered, it seems the initial firmware out of the box on the Tab S is ancient technology compared to the Note Tabs and Galaxy phones which can screen mirror to Chromecast.
I would think Chromecast screen mirroring problem would lie with Google and the Chromecast app not Samsung.
If you are rooted you can use the below app to enable it.

Just more android fragmentation garbage apparently.
I found this article a good read though, but it just leaves an Android user in the blind about what supported features will be available.
http://allaboutchromecast.com/chrom...-about-wireless-display-and-screen-mirroring/
Thing is, I'm not using chromecast, I have a smart TV and just enable mirroring with Wi-Fi, I didn't plug anything on the TV.
Works flawlessly with the note 3, but can't enable it on the tab S.
Would that app be worth trying in my case ?
Fixed?

So after 20 minutes of this I sorted it out. I had a private internet access app running so that all my traffic is encrypted and routed overseas. It just sets up a VPN, so I think if you have a VPN running then it won't work. That was my problem, hopefully this helps you.

10.5 Tab S Directv Sunday Ticket app issues

So I've been trying to stream the Sunday Ticket app the last couple weeks and for what ever reason the video is anything but smooth. I have a strong wifi signal, I've tried both wireless 802.11b and n with my Asus rt-n66, even being in the same room with it and no luck. Yet my S4 and note 8.0 have smooth video on the S.T. app. I can stream netflix, HBO Go no issues. Anyone else try the ST app? If you have it can you please test?
Thanks,
Mark
So it seems the Tab S is not the only tablet with these issues. I was reading reviews of the app on Google play and there are several other tablets having similar issues. Nexus 10, tab 4,etc

Cast without wifi?

I am trying to find a way to cast movies from phone to tv in my camper without using a wifi network. I used to be able to cast from my Note 3 on 4.4 but apparently miracast is broken on 5.0.2? What would work without internet and a wifi network? I read that a Amazon Firestick would work once it's initially set up on a wifi network but haven't been able to verify.

I recently moved and had to wait for my ISP to setup internet. It idn't work for me even with a internal network. It needs an outside internet connection for setup to complete. None of my Amazon devices or Chromecast worked and only one of my Plex clients worked because it was previously configured for automatic sign in.

Here is how I do it when I travel but you may need a intermediate device. I would download movies onto my phone, start up my hotspot, use another device to setup the chromecast and then use an app like Local Cast to cast the movies from my phone to the chromecast. Recently I tried it and Local Cast wouldnt see the chromecast from my phone. So I moved the movies to my tablet and my tablet over the hotspot could see the chromecast and then I would stream them that way.
Because you arent actually pulling data for the movies (other than whatever background processes are running on the tablet) it doesnt sap away at your hotspot data.
I downlaod my movies to my Note 3 which is currently a wifi only device. I then set up a hot spot on my pixel xl and set up the chromecast. Then using allcast I was able to connect and cast to the chromecast. I swear this was much easier when miracast worked. I haven't tried the Firestick yet to see what happens.
I tested a few things to see what would work with the chromecast. Hotspot had to be on and left on. I could never get "guest" mode to work but the info says it should work so a guest can cast without being on your wifi network. No clue how to make that work yet.
I'll try and test firestick tonight. I also have a spare wifi router that I might take and see what I can do with it.
The firestick did not work.
This is so annoying since it worked on Android 4.4 and now on 5.0.2 it doesn't. I just want to simply cast my phone to my tv in a camper without a wifi network. I suppsoe I can eventually buy a wifi router but I really shouldn't have to. I wonder if the Note 8 will have Miracast or not?
Miracast works with crDroid ROM

I just got Miracast working with "crDroidAndroid-8.1-20180405-marlin-v4.1" for the Pixel XL. I just went into settings - connected devices - cast - then hit the three dots in the upper right hand corner to 'enable cast'. On my Fire Stick I started device mirroring. Bingo! Fire Stick shows up as connected. Works with VLC and Youtube testing so far. Sound and video work. Rotation of phone to horizontal creates full screen (55" TV) mode. I have magisk 16* installed but there are no settings I used in that app for this to work, just wanted it noted as it is the only non-stock app installed so far.

I posted this in the Pixel thread as well, forgot which forum I was on....

Interesting. I am on 8.1 stock, rooted, and custom kernel. I will have to test again when camping season kicks in here soon. I did pick up a Galaxy s7 Edge that will hopefully cast with Miracast. The Note 3 I was trying to use is retired now.
Once I enabled tethering on mine I was able to cast to my Chromecast with the in app cast button. I either had data disabled (the x over the cellular signal) or I turned on airplane mode then the tethering. This allowed it to work for some reason that I cannot explain in much detail. Basically one of those two things maybe both can't remember causes the traffic to be properly routed locally instead of over the net like before. I accomplished this on stock Android using localcast,YouTube, and Netflix less than a month ago.
