I have one Galaxy S9 phone and one Galaxy S9 plus phone. I am unable to cast the videos directly from youtube to TV from both of these phones and in older Galaxy S series phones this is very straight forward. I have tried multiple options without any luck and I also found that lot of people have the same issue when I googled. I have contacted Samsung support and they told me that you need to install "Samsung Smart View" app from Google play store. It seems this app doesn't come in built unlike previous versions. Unbelievably, when you pull down the buttons below settings icon it displays smart view button even though it's not installed on the phone. It is not detecting any devices until you install "Samsung Smart View". I don't know whether this is intentional or they just screwed this up.
It seems Samsung released a patch update for this issue now.
You don't use Smart View or anything else to cast. The YouTube app has a cast icon if it sees a Chromecast on the same wireless network. I'm a little confused by your initial post. There hasn't been any issue using a Chromecast with my S9+.
What?

Same here.
Apps with native Chromecast support (e.g. YouTube, Netflix, Google Play Movies etc) have always worked perfectly on my S9+.

The following steps seems to resolve the issue
After lot of trials and errors, I am able to resolve my issue thanks to Aliaksandra from google chromecast product forums.
Here are the steps:
1) Go to Settings->Select Device Maintenance
2) Wait for optimization to complete and then select Optimize now
3) Then select the Storage tab located at the bottom of the screen
4) Click on the three dots located on the top right and select Settings->Click Clear Cache
5) Select the Memory tab from the bottom of the screen and click Clean Now
6) Reboot the Samsung device and then try adding the account once again.
This did the trick for me and my friends also.
Has always worked fine for me. I have an S9+, one Chromecast Ultra and one Chromecast. No issues.

What on Earth are you talking about? First you talk about Smart View. Then you talk about a non-existent firmware update. Now you're claiming "device optimization" is a cure for an issue that doesn't exist. Where does adding an account factor into casting?
I'm not sure you understand how Chromecasts even work. Are you even casting from within apps or just mirroring your screen?
Can you provide a link to the Google forums that talk about this issue?

Hi Averix,
Bro, you need to understand people do have these kinds of issues. I agree you may have spent more time resolving these issues and helping people but please don't assume you know everything bro.
I know how to use Chromecast works and been using it for last 3-4 years. As explained in the OP, I have the problem in casting videos from youtube on S9+ phone to TV which is working fine with previous versions of Samsung Galaxy phones. When I raised complaint with Samsung tech support, they gave me number to contact them. When I contacted them, they made me troubleshoot the issue and finally they told me to install Samsung smart view app from play store and after installing this also it still not worked correctly. After couple of hours later my phone displayed a message that there is software update and after this update the cast icon started showing up on youtube videos intermittently. Once I followed steps mentioned in the links below, now it is working for me.

I read through that thread. It's a cluster of different issues from Chromecasts rebooting or not connecting, the Home app not working with mirroring, Smart View not casting properly, etc. There isn't any common thread of a core issue. I'm glad the voodoo solution solved your problem, but having dealt with hundreds of Chromecasts for commercial installations, I think your case is extremely isolated. I would be curious to see some replies if anyone else is having this issue on here.
Again, I'm glad yours is working now, but I think your solutions of phone software update and cache clearing are actually irrelevant. I'm betting the phone reboot cycles had a bigger impact on flushing the cast associations that your phone thought it had. Using Smart View to cast a mirrored image of your screen to a Chromecast is one of the most horribly inefficient way of casting. If an app has native casting capabilities, always default to using that first. Otherwise, you're literally streaming content to your phone, rendering it on the phone, encoding the content being rendered on your phone, and sending it out from your phone to play as video on a Chromecast. When you select a cast icon from an app, it typically just tells the Chromecast "Hey, go out to the internet and stream this video directly. I'll give you some credentials so you can watch that DRM video. Let me sit here and idle my processor saving battery and making my owner happier."

Thanks, bro.
Installing the SmartView app seems to have helped with my issue.
I have three TiVo units, three Rokus, and two Vizio smart TVs. I just switched from my S7 Edge to the S9+ ; the S7E would show all these devices when casting from YouTube app.
When I tried to cast from YouTube app on S9+ to my TVs the only devices I would see were the Rokus. Neither TV and none of the TiVos would show as options for casting from the YouTube app.
After installing the Samsung Smart View app all of the devices were listed! Thanks!

Casting to a Chromecast is not the same as talking to a Tivo, Roku, or smart TV. The discovery protocol is different. YouTube maintains the DIAL protocol which is why it shows up on Tivos and Rokus. In your case, open the YouTube app and look at all the devices you see available to cast from. Now open Hulu, Movies Anywhere, or other Google Cast compliant apps and you will see a much smaller list corresponding only to devices broadcasting as Google Cast receivers.
This thread is mixing up Google Cast (Chromecast or Android TV receiver), Miracast (screen mirroring using Wi-Fi Direct), the DIAL discovery for streaming content, and apps that use multiple protocols (SmartView). Each one has it's own issues and gotchas when trying to make things work. The problem with the advice in this thread is that there is no panacea for all the myriad of symptoms the original poster and you have. I'm glad your YouTube is working now, but that doesn't mean you have fixed a Chromecast issue because they are targeting different endpoints.
I will let those of you who care do some research on your own as to how all these things are different if you really want to understand what is going on.
DIAL protocol
Casting, DIAL, Airplay, etc. and Fire.
Chromecast change from DIAL to mDNS

I've had the S9+ a month or more now.. casting videos has always worked for me. I can do it from Home, from YouTube, Plex, and I also have used Videostream. All work fine.
Casting works fine for me except for Plex for some reason
I'm running into issues with my S9+ and Chromecasts as well. Sometimes my S9+ doesn't detect my Chromecasts until I reconnect to my wireless. This goes for Youtube, Hulu, Netflix, even the Google Home app. This has never been an issue before and the only thing that has changed has been my new S9+.
The S9 cannot mirror to Chromecast. Samsung has stated this time and again. It has to do with Oreo and the processor in the S9.
Seems ridiculous that I spent $800 on a flagship phone and have to use a 5 year old LG phone to cast Spectrum cable to my television.
Chromecast has worked on my S6, S7 & S8, but NOT on my S9+ OR the Note9. Really sucks... Anyone figured out a REAL fix yet?
Hi, I have an LG G5 Android version 7.0. I just recently purchased a Roku Express +. I had one of the very first generation Roku's 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, made sure there were no available updates for my LG G5 or Roku, 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.,

Okay, 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.

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.
My pixel 4a can't find my LG webOS TV SM8200PLA. Is there a way to improve the built in casting feature?
after 2 months I didn't even find a way to improve this feature
Same problem here. But it's the problem when mirroring is attempted from usual settings option. However, mirroring works when done through YouTube.
I need to mirror some other things from screen e.x zoom meeting.
This is a "problem" since years on Google phones. Seems that streaming only works with a Google chrome stick.
