Miracast / Screen Mirroring / Wireless screen not working on Android Pie - Xiaomi Mi A2 Lite Questions & Answers

Hi,
I received today my phone, I updated to Android Pie, and now I see that I cannot discover my TV which supports miracast. I also tried to switch off Wlan.
Of course I considered downgrading to Android Oreo, but I read it's a bit troublesome (dual sim stops working when downgrading).
By the way I'm asking to xioami forums too (I cannot post external link), but I don't think I can expect a fast fix
Any idea? Thanks.

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.

LG G3 Miracast failing

I had an S4 and a 2013 LG TV which could receive the Miracast from the Samsung S4 just fine.
I've upgraded to a G3 and it's seems to be in compatible with the LG (that's right LG) TV.
It connects, then just disconnects, no errors either side like this:-
https://www.youtube.com/watch?v=Ck8TLBqHxoQ
I've even gone as far as to factory reset the TV, just in case (It's had a few updates since purchase).
Am I missing something (Is there a known work-around or something) or was LGs flagship phone not tested with their own Smart TVs?
Any ideas / help appreciated.

For me same constellation. Same issue.
Bevor with s4 work.
Shame LG
OnTheRoad
Same with my sony tv as well very hit n miss as is nfc
Same here I cannot use miracast or wifi direct with my new sony tv; DLNA works though
Official bug???? How can we fix it?
thank God someone finally posted the same thing as i thought i was the only one experiencing this.
g3's miracast won't connect to my Toshiba tv.
it just shows wifi direct connected, then nothing happens.
went to the mall to try on other tv brands samsung,sony and even LG but miracast won't connect.
so i gave up and just told myself maybe it's because the phone is still new.
was using version 10A.
now i'm on 10B and still doesn't connect.
Looks like LG need to fix this but still haven't addressed this with the latest 10b release
Maybe lg is not even aware of this issue? How do we submit this bug?

I have noticed this with my previous LG G2 as well. Somehow lg tv keeps loosing stability of the miracast or dlna server.
might be something related :
hidden menu > MirrorLink Test and it will Force Close.
So is there anything we can do about this? Does this problem exist in all version of g3?
Miracast works perfectly over here. Miracast on, recognizes Panasonic VT60, off we go.
I gave up and bought a Chromecast never worked for me
Verizon G3 works fine for miracast on my 2013 F8500 Samsung. Try not connecting WiFi to your router or connect WiFi on 5ghz band. You will achieve better stability in the signal. Also don't have your tv connected via WiFi. Miracast may conflict,with your current WiFi connection or interfere when on the 2.4the band, just my experience as I also use widi on pcs. The WiFi chipset varies from phone to phone, LG may use one chipset that has more issues than Samsung
Hey guys, I just found a solution for it.
First, I read the NFC tag that came with my LG TV to connect it. It asked for Tag On app installation and after that, for the LG TV remot app. Bam! Miracast is finally working on my LG TV. Probably any library was missing and now is all good! :laugh:
Please try it and let me know.
Same problem here with a LG Nexus 5, Android 4.4.4.
It plays with an Asus Zenfone 4, though without sound, not sure if I'm missing some essential bits.

Try what? What does this have to do with what TV you use? What "Tag On app installation"?

In my last post, I described a procedure that worked (temporarily) to connect to a LG TV, but never mind... it's not working anymore. Back to the point zero!
Any solution guys? Its a problem with g3. I have g2 as well works perfectly fine

Did Miracast come with your 2013 8500 Samsung, or did you have to get the Samsung Evolution Kit to support it?
I turned on the hotspot kinda thing on the tv...connected my lgg3 to that WiFi. (Tv is still on home WiFi) and it works just fine.

Miracast or Screen Cast option during Hotspot being active?

Is the above at all possible? I've searched around for various options for what I'm looking to do and all avenues appear to have either been patched or I may possibly be on the wrong firmware.
Phone is a uk 855
Current FW is 4.4.2
The problem that I'm having is Chromecast while using my phone as a hotspot. I'm allowed to cast various apps, netflix, etc and they all work fine but what I can't do is cast the screen. This is very important to me as I'm trying to create a wireless connection in my car (As other users have done with different models).
On any of the google Nexus phones it's simply a matter of going to Settings>Display>Cast Screen. Is there a way of getting the G3 to do the same? A hack? A workaround? If there is, I can't find it so really need some guidance.
The issue I have is that Miracast disables the hotspot rather than using it and Chromecast just refuses to work without Wifi being on (which again would disable my hotspot). I simply want to connect my phone directly to the chromecast with no outside source of Wifi.
Apologies if I've missed anything important. I wasn't sure what information would be required.
Thanks
Updated to 5.0 and I still don't have the same options as the Nexus & Sony versions. Is there perhaps a custom firmware that I could use?
Sorry but I think no
Surprised to find a "No" with Android, a first for me

Miracast / Play To / Wifi

So I took the plunge and forked out for an Asus Miracast dongle now that Netflix is finally available where I live.
I had seen several demos and explanations on internet suggesting that you can mirror the screen of any app using the Play To function. That is technically correct, but what I can't understand is that in both of the links below, the video / screen shots clearly show the "Play To" mirro function being connected to a display device AND the phone's Wifi connected at the same time.
I cannot replicate this. Every time I connect the Play To / miracast, my phone gives me a message saying that the Wifi will be disconnected while the Play To connection is active, which effectively means that I have to rely on mobile data through the SIM card to stream the media from Netflix!! Not exactly what I had in mind.
Has anyone actually achieved what the links below suggest is possible?
Is my problem due to the fact that my ZF2 is a 550ML?
Or could it be an issue with the Asus dongle?
I also have several other older Android devices with "Play To" / Screen Mirror functions, and they both behave the same, but I thought that the ZF 2would be capable of handling both connections at once?

Just tried with my Samsung TV and both are connected simultaneously.
Sent from my ASUS_Z00AD
Seems to have been a glitch. It was connecting via Wifi, not Wifi direct, but trying again the next day it worked perfectly...
I've got a zenfone 3 x008dc and since the latest update firmware, the "play to" function has disappeared from my quick menu setting and also from cellular networks. i tried searching for it in settings and it comes out blank. I'm not able to mirascreen or miracast on to my tv anymore. can anyone tell me what I have to use now as an alternative or where to find this function?

Question Screen mirroring broken with Android 12 / OOS 12 update?

Hi, so ive been trying to mirror my phones screen to my Samsung smart tv wirelessly. I go through all the steps, making sure the phone and tv are on the same wirless network etc. It the tv finds my phone and vice versa but after actually trying to connect . I get connection failed on the phone side and sharing cuts itself off. I saw on another forum that other people had the same issue since the last offical update. Anyone here had this issue or know of a fix?
I haven't seen anyone mention it, but a lot of us use Chromecast with our Smart TV....
