Chrome cast issue / Wireless Projection issue

My P30 Pro, my wife mate 20 Pro and my dad mate 20 don't have chrome cast option for whole device screen mirror. And the wireless projection not working at all. I been Google and seem to norm and no one seem to use this much.
App cast like Google photo and YouTube is fine.
Anyone facing issue like this as mine?

Yes, same issue here, the 'Wireless Projection' toggle brings up my Sony Android TV as an option but when i select it nothing happens. Within Youtube, Google Photos etc the cast feature works fine to the same TV. No issues with my previous Pixel or Samsung device.

Indeed. My old LG G6 and my dad Samsung chrome cast work fine. Guess it's huawei own issue in software?

What I found on my Sony Android TV, it will cast when you switch to wireless projection as "input" on TV, where you see the screen saying that it is ready for it.
On Samsung, it took few tries but the TV eventually accepted the cast.
The implementation may be buggy or not fully/widely compliant. Yet.

I suspect EMUI supports Miracast but not Chromecast when using that Wireless Projection action, which is a shame. You have to go through the Google Home app to chromecast screen content.
Hoping this is something Huawei could eventually add.

I am using my chrome cast and it is working fine.

What works fine?
P30 Pro 256gb Aurora Power

Same issue on the P30 version of the phone to a 2017 Samsung TV. Casting youtube will bring up the app on the TV (although I seem to have to do it twice everytime). However wireless projection does not work.

I will check this feature with chrome cast and update u shortly

I found I had to install Mirrcast to be able to see any chromecast devices. Just have to run as an app and not from the pull down bar.
P30 Pro

Thank you for this. I'd been looking for a solution. I have a Sony Bravia XBR-55X900E and a Huawei P30 and couldn't get screen mirroring to work (although no problems with my Samsung S8). I'd seen that page on the TV by selecting the Screen Mirroring input but thought it was just a information page. Once that page is shown, I select Wireless Projection on my P30 and now the TV shows up for me to select it. (When I'm not on the Screen Mirroring input, I never see the TV as an option to select on my P30). I click on it and it connects. I wondered if that was a one-time setup thing and if I needed to select the Screen Mirroring input on subsequent connections. I found I do, so now I need to program a way to do that from my Harmony Remote Thanks for solving this for me!

Ignore this post, can't find the delete button.

Reading some ideas here I just came up with a method for Samsung 6300 series that seems to work:
- go to "connection guide" in the source menu
- enter to "mobile device" section and click the button that appears in it. Then the TV will appear in the devices list of the Wireless Projection in the Huawei phone. BUUUT still don't try to connect.
- Leave the connection manager in the TV (go to home, for example)
- now you can select the tv in the phone list and it will connect.
It worked for me twice. I'll have to test it more because I have the feeling the working of this wireless projection between Huawei phone and Samsung TV is a bit random. Hope it works for you.

Hi there,
I bought me a new TV some days ago with Android TV on it. It is a Philips 55 PUS 7304.
Everything works fine on the TV except wireless connection from my Huawei P30Pro.
I just don't see my TV when I turn it on. I even see the TV from my neighbour, but the Philips doesn't appear.
Somebody else got the Problem??
On my Tablet with Lineage OS the TV is there in a second and wireless connection works like a charm. On my Huawei P30Pro I can only stream inside of an app. I can send files to the TV, I can mirror my Netflix, Prime, Google Chrome etc. but I just don't get wireless connection ti run.
Please help me. What am I doing wrong?

Really nobody here with a Philips TV???
Does it work with a Philips with Android TV and the P30Pro for anyone?

I found that if you open up the Google Home app and find your chromecast in there there is a 'cast screen to TV' option - this works 100% fine on my P30 Pro.
As listed above, wireless projection only works if you find the 'mobile device' input of your TV.

I have the same TV as you and the same phone as you, and no, wireless projection just doesn't work.
Searching for compatible device, but never finding my TV.
I mainly wanted to use it for desktop mode on my phone.

Thats exactly what I wanted to test. Desktop mode seems to be a very cool feature but it doesn't work.
Does anyone know exactly why?
Is it really Wi-Fi Direct?
Really strange that such a big company like philips doesn't support this and nearly all others do.
@Nu72 This works for me too. But this doesn't support the Huawei Desktop mode. Otherwise I can cast my tablet too. This is a lineage Android one and it works without any google home.

K20 Pro screen mirroring issue

I tried mirroring my K20 pro screen to my Samsung smart TV and i am seeing issues with mirroring.
Initially it connected successfully to the TV , and then it automatically disconnected after some 30Secs , after that i had no success mirroring the K20 pro screen to TV.
Anyone else facing this issue ? Is this a common issue or just with my device ? Should i return this and go for a refund/replacement.

Download Google Home App from Google Playstore and it mirrors to my Sony Android TV straight away.

You must disable battery optimization of cast app and wfd app to fix this.

I have tried the variety of proposed solutions i.e installation of Google home, cast and casting apps update, permissions for the cast app and the wireless display certification but they are not working for me. I keep getting the message on the TV that 'try using a mobile device instead to collect'.
Is there a solution for this?

Cast screen to Samsung TV?

Dear all,
I'm happy with my Mi 9T Pro - running MIUI 11 Global - for anything but the cast feature.
I have a Samsung TV and when I had a Samsung S9 I was able to seamlessly cast the screen content to the TV.
With Mi 9t Pro anything I tried failed.
Is there a way to accomplish this specific request? Might a custom ROM add the needed feature - protocol - libraries that enable this?
Thanks!

Playstore - Video and TV cast /Samsung TV

Both smartphone and tv must be on the same 2.4 GHz wifi network (not 5GHz). Enable Bluetooth.
Start your TV.
Mi 9T Pro: Settings
> Connection & sharing
> Cast
> Enable Cast
Be patient the first time. Repeat the procedure a few times.

This is correct when you use a WiFi connection for your TV.
When you use an UTP connection for your TV to for example your router it does not matter what kind of WiFi network you are using.
Both (2,4Ghz of 5Ghz) will then work.

Thanks everybody for your answers.
@hewlett2008, thanks but I didn't explain well my request: I would like to mirror phone's screen to TV, so the application you suggest does not accomplish this task.
@actiyo and @Snah001, I made all possible test but did not manage to make it work.
I tried with TV connected via cable and via wireless, and both times activating the cast feature on the phone didn't make anything happen.
In a random attempt I also manually added TV to the phone via wi-fi direct, and TV did ask me to authorize the connection, but even in that case the cast feature did not work.
I find it weird that this feature is listed as one of MIUI 11's improvements and it just does not work with a large selling TV producer like Samsung.
Any help will be appreciated.

Double post.

Weird. I can cast to my KU6400 Samsung.

I think mine is a quite recent model: MU6400, 49"; I purchased it a couple of years ago.
I used to mirror my phone to quickly show some news articles or funny Whatsapp messages to my family, and I miss this feature quite bit.
I'm not a total newbie of technology issues, but this problem is baffling to me.
I guess I will end purchasing a Amazon Firestick or something similar just to use this feature, but would try anything before because the TV is hanging on a wall and any device connected to HDMI would not be nice to see.

Cast problems
I have a Xiaomi mi9t pro . I have 2 tv . One a LG newer one and one Samsung "old" one . Both smart TV . After update from miui 10 to miui 11 cast won't work on the Samsung TV from the app like YouTube. Tried everything . No matter what I selected 2,4 ghz or 5 ghz network . With screen mirroring is working , but I find this kind of useless because I don't like how I see the movies in frames . Anyone with some ideas ? I have 2 another phones in my house , both working with the Samsung TV so it's clear is not the tv the problem !

Well, screen mirroring is exactly what I'd like to use.
Could you please tell me what are the exact steps you perform (on both phone and TV) to activate screen mirroring?
Thanks in advance!

MIUI 11 - Cast not working?

With miui 10 I had no problem casting screen to my Sony Bravia.
Just upgraded yesterday (finally). with miui 11 everything feels great except casting no longer seems to work. It still recognises my TV but fails to establish any connection. Is this a known problem?

Yes, it us.
But there is a solution.
Go to developer options and enable wireless display certification.
Than go to "connection and sharing"/"wireless display and enable wireless display.
Now you see some stuff. Go to "operating channel" and change from auto to 6 or 11.
Now connect your tv.

I see the extra options after enabling wireless display certifications.
But still can't connect wirelessly, even after changing the operating channel. I even tried changing some other parameters, still no go. Nothing happens after I tap on my TV name.
Thanks anyway.

Cast is working fine using Chromecast on V11.0.8.0.QFAEUXM, after following OEL's setting recommendations. I never tested it with a Sony Bravia...

wireless display mi mix 3 after miui 11
hello, I followed your instructions and I managed to connect my mi mix 3 in wireless display my samsung smart tv and thank you for this. When I then restart or turn on the smartphone, I activate the wireless display, and I have to set operating channel 11 again, otherwise it won't work. Why is channel 11 not stored?
second problem. the home modem is dual band. Samsung smart TVs connect to both networks. But my mi mix 3, connects in wireless display only if the TV is connected to the 2.4 ghz wifi network. If I connect the TV to 5.0 Ghz, the phone does not detect any Samsung smart TV. Please can you help me. I would prefer to use 5.0 in wireless display. Thanks

Screen casting problem in Mi A2

I tried to cast my Mi A2 to LG Smart TV and while casting I was only able to get the home screen that too with a settings button, which is not what my phone's home screen looks like. Does anyone know a fix to it?
Also, there is another problem of hotspot and wi-fi not working together now. Any fix for that too?

Ya I am using stock android 10 only. Casting is supported, I can cast my other phones on TV and I can even cast YouTube through other casting app. It's just that I am not able to mirror the screen and also not able to screen cast YouTube directly.
Also, if you are talking about extending feature in developer settings, that I have already tried but no luck, still it doesn't opens wifi and hotspot at the same time
