Screen mirroring through Chromecast or Samsung smart TV problems - T-Mobile LG V10 Q&A, Help & Troubleshooting

Has anyone had any success screen mirroring to either Chromecast or a Samsung smart TV? If so, are you rooted or stock? If rooted, what ROM?
When I try screen mirroring through my Samsung smart TV the video comes through, but the sound does not. When I try through Chromecast, it disconnects immediately when I try to connect.

So...no one can reply after all this time?

I would test, but my 3 year old, in the past week in a half, broke both my chrome cast (not waterproof) and my 55" Sammy (die-cast Lightning McQueen)... My panasonic and LG are both stupid TV's... Sorry I can't help... But I do feel better now that I've vented a little...

I have been able to cast to my Chromecast on both my Sony 46" and my 32" Emerson with no problems. I have an older Chromecast(purchased just 2 weeks before the new ones can't out). Will try mirroring to my Sony when I get home. I can also cast if the Chromecast is connected directly to our Skny home theater system.

I am able to Miracast to my Samsung Smart TV. It occasionally disconnects and has some noticeable delay but otherwise works fairly well. Haven't a Chromecast to test with though. I am rooted with the stock ROM for the record.

no issues here.. try this..
be sure phone is in portrait mode when you initiate screen mirroring. Once connected, than turn landscape. Regarding chromecast, once connected DO NOT use home button 2 escape, just hit back button a few times..

Need Help w/ Mystery Video Screening

I've got a peculiar issue I need some help with. My son often uses my tablet to watch movies or play games on my tablet. The issue is recently he's been doing something that projects/streams whatever you want to call it, it displays what's on the tablet on the downstairs television. We've never had this issue before, but then again the TV is new, it's a Panasonic Viera. Great TV with a lot of options, in fact it's connected to my local network.
My guess is there's some app on the Transformer that's interacting with an feature on the Panasonic. It is very cool feature, like Apple mirroring, however I don't know what my son is doing to activate it. He just randomly turns it on and I'll be downstairs watching TV and the screen will change. That's another really odd symptom, the TV input isn't changed, it's still on HDMI running cable TV, so whatever he's doing is overriding the TV. I check the tablet and there's no open app, like he's turning it off and on because the TV only does the mirroring for a few seconds. Another guess is that the app opens, then he tries to close it which is why I just see a couple seconds on TV.
Does this sound familiar to anyone? Is there any other info I can provide to help diagnose? I've got too many apps to list.
Android Version 4.1.1
It may be interacting with your TV's Viera link which acts like Chromecast. You could turn off the Viera link when not needed to prevent this from happening when you don't want it to.

So any idea what app or process is doing this on my Transformer?

Screen Casting From Android Is Now Live w/ Chromecast

You can now mirror your screen when using a Chromecast with the Note 3 running 4.4.2. Go into Settings >More Settings >Screen Mirroring to enable screen casting through your Chromecast. You can also cast directly from the Chromecast app if screen mirroring doesn't work.

I must be doing something wrong because I can't get it to cast...

Figured it out. Even though the app said it was updated today it was not the latest version. I side loaded the latest version and it works. It is too choppy though.

It's working fine through the Chomecast app for me. I haven't tried any games but everything else is smooth including 1080p videos that were recorded on my phone.
I can get it to mirror my screen through the Chromecast (not through settings) but I get no sound. How do I get sound.
Note: My chromecast is plugged into my Onkyo receiver, does that make a difference?

Probably so. I have screen mirroring working thru the Chromecast app as well and it does audio just fine. Might be something going on with that receiver. Can you remove it and try just a direct connect to the Chromecast on the TV? Haven't tried thru the Settings way.

Turns out that power cycling the Chromecast solved the problem. I now get sound.
Reboot of Chomecast worked for me to get sound working. Also games look great!
I see no option to Mirror in the Chromecast app. It says I have the latest version.

Be cautious with games. My phone shut down several services and a warning screen appeared stating my phone was too hot.
Does that mirroring work directly from chromecast to phone or do you still need a wifi network to connect them both to?

You still need to use Wi-Fi.
I'm on Android 4.3, Beanstown build 6, so I can't screen cast Is there an update path I can take (possibly new ROM) that will get me 4.4 and the ability to use this new feature? (I have Chromecast app ver 1.7.4)
Could people who have it working SMOOTHLY (to me not smoothly = not working) at 1080p please post the wifi setup they are using? (Router/AP model and 2.4 or 5ghz, is it in the same room, other devices connected, port forwarding or QoS or other router config, or anything else noteworthy)
I haven't touched my chromecast in 3 months because it basically didn't work for anything I wanted to do (main thing is playing photos/videos shot with camera on a bigger screen). Back then I was using a wired router and a Asus EAN66 as wifi AP (box-claim speed of 450 mbps) sitting within 10 feet of both phone and TV/Chromecast in the same room but it was horrible - I was lucky to get maybe 20 seconds of smooth video max. Then it would crash. Much faster to transfer files to computer via usb3 or sdcard then play on TV. Similar story on a Linksys E1000 but I forget which was worse.
True smooth 1080p screen mirroring... that would be nice. Truly something that would wow people. I now have Netgear R7000 (model name "Overkill") and it's 5 feet from the TV so it really better work now! I'll report tomorrow when I can mess with it.
I had it working smoothly. First I had to update to most recent chromecast app from google play in US, then once I tried screen mirroring option in the app, it would connect to my chromecast but show nothing. After doing this the chromecast then wanted to reboot and update itself to a later software build. While it rebooted rebooted note 3 and laoded up the chromecast app, option was there to mirror to tv so I chose it and it worked flawlessly and smooth even playing games. I was using stock android TW 4.4.2 and played trials frontier. I have a netgear WNDR 3700 V1 router using 54g (2.4) to connect phone and chromecast to. The tv was like 1ms behind what was displayed on phone but still worked flawlessly. I had my phone power saving mode on and cpu power saving checked. Even with this power saving it worked great for web browsing, videos, and games. Phone did get hot and battery drained quickly! I also use WPA 2 encryption and security!

I was running CleanRom with 4.3, and swithched to BajaRom so I could use my chromecast screenmirroring. Baja is 4.4.2 snd it worked flawlessly. Problem for me is, I dont like Baja. Im gonna go back to CleanRom 4.3 jellybean. The trade just isnt worth it for me.
Hope that helps ya.

Can No Longer Cast Screen On My 2015 Chromecast

I apologize if this has been covered elsewhere but I recently upgraded my my Chromecast generation 1 to Generation 2 and my ability to cast my cell phone screen to my chromecast from my galaxy s6 has stopped.. it just says connecting and times out.. All apps with native chromecast support work as they should.. Only when I use the cast screen feature from within the chromecast app does this problem occur... Does anyone possibly have any idea on what could be causing this to happen?
Thank you in advance!
I'll have to test this for myself but casting the screen to my Chromecast 2 from my N7 2013 just stopped working all of a sudden the other day. It'll connect and then freeze up within a couple of seconds.
Will try to cast a specific program like YouTube tomorrow and see what it behaves like.
Same problem for me, in the beginning it worked fine, but after the automatic update it started to do problems with the mirror cast and the Google photos.
In the others app it is working good
I so that this is a common problem with the chromecast 2, in alot of phone models

I have almost the same problem, just purchased my chromecast. Everything works except the ability to cast my screen from withing Tablet using CyanogenMod using the Cast Screen option.
When I try it it goes through the process show the device found shows connected then instantly show disconnected. Works on my One Plus One running CM based ROM just fine. So it could be ROM version....
Since its a tablet have to use android Chrome so can't use extensions on it because the extension for Chrome Cast work on my laptop to do a cast screen.
Same problem here using slimkat rom
Updated the tablet to CM12.1 not same ROM but same version as my phone ROM made no difference. Also tried 2.4 and 5 GHz still no go from tablet. Interestingly annoying....

i haves same problem in a lg g stylo i update android 6.0 now wrok fine
Just happened on an HTC M8 too. Everything was OK until now. I have it from December and was working on Android 5 and even on Android 6 until yesterday. Tried to reset it hard from button and soft, reconfigure it and happens the same issue: phone find it and when try to connect screen goes black on TV like trying to receive an image, then disconnects back to backdrop. On the phone sometimes the wifi disconnects from the router and reconnects back when Chromecast is trying to transmit the image on TV. I checked the compatibility phones on page and indeed M8 is not there, but it worked, so is not that.
There is any possibility to take an log on the Chromecast to see what is happening?

Edit: Seems that the issue was the installation of the Viper4Android flashable zip. After replacing system image from twrp backup, everything is back to normal. It connects in no time.
What version of android do your phone use?
I use Galaxy Note 3 android 5.0 with Chromecast app to cast screen to TV attached with Chromecast 2015 device.
There is no default option for casting screen on android 5.0.
So I use Chromecast app to cast screen.
Everything is normal. I can cast phone screen to TV while I'm playing Asphalt 8.
I have switched phones to the Nexus 6P and for the first few months I was able to cast to screen again but now I lost that ability after experimenting with different roms.. yet I can still go to my friends house and cast my screen without any issues on his 1st gen chromecast.. what a strange issue
I switched back to the 1st chromecast, the new one would start overheating lol

Help, Please: LG G5 7.0 Screen Mirroring Problem

Hi, I just recently purchased a Roku Express Plus. I had one of the very first generation Rokus but I haven't used it for 3 or 4 years so I got it all set up and was excited about the option to screen mirror my phone to watch content that I can't cast.
Everywhere I look shows me the exact same information, which is basically to go to my settings in my LG G5, share and connect, select the device, and then, supposedly, Voila! Except there is no Voila!
What ends up happening is that my phone sees the Roku unit and after it finishes searching it shows it's connecting. I've already been into my Roku settings and it sees the LG G5 and also has an abled no prompts necessary for connection. But within a couple of seconds of connecting to the Roku, and the Roku puts up a little purple screen that shows a small device and a large TV screen so it looks like something's going to happen, then the connection drops, Roku goes back to its home screen, and my phone shows no devices are available for connection.
I have tried to Google myself silly figuring out what might be going on. I can't screen mirror remotely from my phone to my TV, which is early generation flat screen and not a smart TV, but with an HDMI cord and a dongle I bought that allows it to work that way. But, of course, when I do that I'm limited to screen mirroring only as long as my battery is running because the dongle goes into my charging port on my phone.
Maybe I am misunderstanding things, but from everything I can see, it appears that my Roku model I have, which is a 3900 series, should work as the Miracast Dongle so that my LG G5 can screen mirror to my unsmart TV.
I have PlayStored myself to death and because Developers interchange the words "cast" and "mirror" it's been install, uninstall, install, uninstall Ad nauseam. For all of the apps that end up just basically being "assistants" and taking me to my share and connect page they are no help at all because even though I go through the process the same problem happens.
I did download one app, which works but is working so horribly because of the app itself that it's useless. So I do know that my phone can mirror through the Roku somehow but it is basically circumventing having to go through the Share & Connect somehow. That app was called Screen Stream Mirroring, and I was trying the free version because I did not want to spend $5 if it wasn't going to work at all. Aside from the annoying ads and limited time, it did a lot of "loading. . .", and had a significant delay. I don't mind the delay, but today it was working worse than it did last night when I first tried it. I'm not sure how it connects, but there was a little tab on the side that said to connect to Chromecast, DLNA, or other stuff, and when I clicked on that Roku popped up as an option because the app saw my Roku so I connected that way. Or any way connected crappily.
I know that's a lot of information, but I wanted to give you everything that I've tried so far. I've also cleared my caches, uninstalled the third party mirroring and casting apps, rebooted my phone, unplug and rebooted the Roku, and I'm not sure if there is a great app I can download? I don't mind a third party app but I can't find one that will work for me right now. So if anybody has ideas on that. Again, I need something that will mirror and not just passed because I would like to view my DishAnywhere or other things on the TV that I can't see through my Roku.
Or, ideally, it would be great to have my phone mirror directly to the Roku without that connection dropping and not seeing the device for some reason. There is no Direct Customer Support with Roku or my model Roku even though I just bought it new. My only options are help center cookie cutter choices you have to select from a drop-down menu, none of which have anything to do with screen mirroring.
Thank you in advance for any experience and or suggestions and ideas to troubleshoot this.,
Kristie
And if no one has any thoughts about how to solve the mirror dropping, how about a good Screen Mirroring App, not Casting, to mirror my LG G5 through my Roku? But it needs to bypass the Screen Mirroring button on my Share & Connect in Settings since that process keeps recognizing, trying to connect, and then dropping the Roku.
I did find one app that used a tab to connect directly to DNLA, Chromecast, etc. that recognized Roku and connected it, but the buffering/loading was horrible, the resolution wasn't great, and the second time I tried to use it the audio was not working. It was called Screen Stream Mirroring by MOBZAPP. Others I tried simply took me back to toggling on my Screen Mirroring button, and that is not working. Bypassing it did work, although the app wasn't great. I am hoping there is another, but I have not had luck since some developers say "mirror" but mean casting.
Thank you in again for your time and and ideas,
Kristie

Can't cast to Nvidia Shield TV

I've tried both smart view (which I believe is only for Samsung smart TVs) and Google home app. I'm trying to cast to my Nvidia shield through the Google home app on the tablet. All I get is a blank screen on the tv. Seems like everything is connected. Home app sees the tv and I hit cast to it and the tablet shows that its casting but all I get on the tv is a blank screen. Anyone else having this issue??

I am able to cast via Smartview to my Sony smart TV, Chromecast and Microsoft wireless display adapter on my desktop Monitors. The casting is a little finnicky when my Smart TV is running an app, e.g. YouTube video, otherwise it works fine for me.
Have no luck to do the reverse casting to the tablet via Smartview though.
I'm having issues as well.
Can't cast from my Tab S6 to the Shield.
The screen goes black but nothing happens.
After a while "screen casting has ended" is shown on the tablet.
Casting from my S10 works just fine though.
No idea what's going on.
I am also unable to cast via the google Home app, just black screen then a message saying casting has stopped of something. I can still cast content from the tablet to the Shield such as video from a streaming app,
Connected
I too was having the same exact issue. All was working fine until recently. What I did was used my phone to connect to Shield via smartview. Once connected I opened smartview on the tablet and was able to connect. I only tried once, however I searched rebooted, etc... Still couldn't find a way until today. Good luck I see it's been awhile since last post.
Yep. Also cannot cast screen to my Sony TV - Neither with Smart View nor Google Home. This is either a problem exclusive to the Tablet, Android 9 or root.
My Galaxy S10 can cast to my TV without any issue, running Android 10 and NOT rooted.
What firmware ect is everyone running? I'm on Pie, SK1 and rooted.
Are you guys using a VPN? If so, try disabling it and try again.
