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.

Is there a way to use MirrorLink?

Hi,
I just bought a new 2015 Subaru Outback and the infotainment center uses MirrorLink. I can't figure out how to get the LG G3 to work with it. Is there any way to get this phone to work or do I need to sell this phone and buy a different model? I just got this phone 2 weeks ago . Thanks guys

Have you tried in Miracast and search for device. I have wdtv live and it is working.

No I haven't. Is miracast an app to download?

Go to settings-share & connect to turn on miracast. You can also add miracast to quick tiles settings.

Thanks! Will try that

Miracast support

I know Google dropped Miracast awhile ago, but I really really need it. Chromecast just isn't cutting it. Via build.prop (additions below), I've been able to see the Miracast device but it won't connect. Occasionally I'll even see my homescreen pop up, but it will immediately disconnect. I remember having this problem with an HTC 10 and it had to do with the wifi setting being in battery saver mode. I'm currently unlocked with Magisk on 8.1.0.
Has anyone been successful in getting Miracast to work??
build.prop modifications:
persist.debug.wfd.enable=1
wlan.wfd.hdcp=disable
persist.sys.wfd.virtual=1

I've not heard anyone getting it to work on the Pixel XL 2. Other than I saw this post in the Nitrogen thread here

Just use All Cast. You will need to pay for it, I think it's like $5, but I've been using it for years. Works great and with Chromecast and pretty much anything that allows DLNA. I cast to two TV's, my Nexus Player, XBOX, etc. using it.

Unfortunately I need to it mirror my screen, not just play media. Thanks though!

Hi folk, please I need mirror my Pixel 2 XL on TVs for my job. I've Chromecast ultra but it doesn't work with P2XL (it seems some technical issue made by 8.1.0) in the meanwhile I'm waiting for fix by big G do you know if All cast can do this job?

This might sound nuts, but is that Chromecast Ultra using a wired network connection? I have no idea the cause but i've had issues with some devices (a samsung tablet for example) connecting to the Chromecast Ultra when it was plugged into the wired connection, often just insta dropping, but it worked flawless when they both were using wireless. Other devices like a Nexus 6p connected perfectly in both network configurations.

Any idea which custom ROMs support Miracast besides Nitrogen OS Oreo? I really need the screen mirroring ability to a windows 10 laptop.

Cast display of P2XL Magisked on external monitor

Hi folk, as title is there a way to cast/mirror display (video and sound) of my P2XL Magisked on external monitor?
I need it for my job
Thank you

I'm not shure what you mean by Magisked, but you need a Chromecast on your monitor/TV/projector
Sent from my Pixel 2 XL using XDA Labs

You're right! I didn't explained it! Being Magisked it means like It's rooted so I could have an easier/allowed way to do it!
Anyway, so the only way is using Chromecast?
Because I've it (Chromecast ultra) but I don't have WiFi at home so I can't use it.
Do you have an idea to use an alternative way?

I thought so, but as far as I know there is no other way. The pixel also doesn't support HDMI on the USB port as far as I know.
Maybe you can use your phone as a hotspot.

Atom is correct. Here's a Pixel 2 issues & ideas thread here

Also I remind problems between P2XL and CU with Oreo. Right?
Few months ago I tried to connect them but didn't work. Do you know if now is it working? (I'm not at home now because job and my CU is there so I can't test it)

I use wifi hotspot on my phone to connect to chromecast to project the phone onto the screen. Really a complicated way of doing something which should be so simple.

CU = Chromecast Ultra?
I can't remember any problems on my wireless network. However, I use the mirror function rarely.

Smartview Not Mirroring Properly

I think Samsung borked something up in Android 10. or at least in its Smartview app. I am unable to mirror to a Miracast WiFi adaptor, nor to a Miracast enabled TV. I enabled Miracast on a Sony TV and connected my Note 10+ to it. It connected to the TV, but it is not mirroring my phone's screen. It will show my photos and videos I have in Gallery, but it won't cast a video from Netflix, Disney+, Prime Video, or Movies Anywhere. I tried it with a Microsoft Wireless Display Adaptor and got the same results.
My Galaxy Tab S5e has no problems mirroring to a Miracast TV or Miracast wireless adaptor. I connected and mirrored my Tab S5e to the exact same devices my Note 10+ connected to. I had no problems playing content from the same apps that I tried on my phone. My Tab S5e is running Android 9
Before I upgraded to Android 10, I had no problems mirroring my phone screen using Miracast.
I have tried rebooting my phone, clearing the cache on both Smartview and the phone, and clearing the data on Smartview. I have also reset my network connections on my phone.

You might have it in Dex mode instead of mirror mode

How do you try to mirror your screen?
Because i go in smart view and from there in smart things. There i have the option to mirror my screen on to my TV.

That is correct. It connects to the TV and Miracast adapter, and shows a borked up version of my phone's screen.
I get the same results with and without Smart Things installed.

Yes. I've even tried a couple 3rd party Miracast mirroring apps and got identical results. Samsung borked up something either in Smartview or Android 10. I'm thinking Smartview is the problem.
I just tried it on my Samsung smart TV and got identical results. I couldn't get it to mirror properly on three different devices: a Sony TV, a Microsoft Wirelles Display Adaptor, and a Samsung Smart TV. It could be an issue with DeX, but I can't find where to check.

Can't claim that the smartview is the problem because i don't have any problems what so ever!

What model Note 10 are you using? I have the Verizon Note 10+ 5G. I did not have this problem on Android 9. My Tab S5e (Verizon), which is still on Android 9 is having no issues screen mirroring.

I just discovered that my Samsung TV won't mirror to my phone. When I try to mirror from TV to phone, all I get is the audio. I don't get the picture. Before upgrading to Android 10, I could watch what was on my TV on my phone (comes in handy when I am in the kitchen).

Yes. As well as clearing app cache and app data for Smart View. And it is a fact that my phone is not screen mirroring properly, not an opinion.
I'm tempted to do a factory reset. I just don't want to go through the butt pain of setting everything back up.

I think Smart View is a buggy thing. My phone won’t connect unless the source is set other than HDMI 1 (Sky). Even then I can’t set it to watch TV on my phone.
For me, the most annoying is the fact that I can’t zoom in while playing video in Smart View, like I can when playing it on the phone. Every time I try, I get the error on phone: “Zoom is not supported for this video size (176 x 144)” I’ve no idea what that means, whether it’s to do with Smart View, the Video Player or the TV its self.
Has anyone tried it?

My 10+ won't mirror, but my galaxy tab 4 works perfect.
Maybe it is the phones. Maybe it works flawlessly with Samsung TVs only.

You are not alone brother! I am having same issue with my a70 after android 10 upgrade. Thank you.

Looks like Sammy is deprecating Smart View come October so likely not going to be investing much in fixing defects.

Btw, I also tried it using both One UI and Microsoft Launcher and neither worked. I'm wondering if it is because of DRM.
