screen mirroring not working on Smart tv after rooting

hi everyone, I noticed that after rooting (I9195) screen mirroring function is not working on my smart tv. Although it functioned fine before rooting. It does connects but immediatelly disconnects from tv without displaying phones display to tv. Meantime my Note 8.0 (non rooted) screen mirroring works fine. Any ideas for fix without root removing?

I've been looking all around for a solution, and it seems like the best solution is one that leaves the phone temporarily unrooted (until you reboot):
http://forum.xda-developers.com/showthread.php?p=43453374
I've seen some mention that it still works fine with their rooted S4, saying that the custom recovery is at fault, but I can't even find the stock recovery to flash and find out.
Personally, I think I'm going to just flash the stock firmware and stick to being un-rooted. The only reason I'd be rooting at this point would be for Sixaxis support, but I barely have the time to go and use such a setup.

Some miracast related questions

I am happy with the way Miracast works with my Nexus 7 2013 and Netgear PTV3000. Except for an occasional 1 sec slip, the screen is mirrored perfectly. Though there are some things I would like to change.
1. Is it possible to show a video full screen in TV (without the previous, home buttons)?
2. Is it possible to turn the tablet's screen off while the TV portion continues to work? Currently, when I turn off the tablet display, TV also goes blank.
3. Is it possible to route Skype and Hangouts audio to TV? Currently, when I video chat in these apps, video is shown in TV, but audio gets played through tablet.

Mirracast is for screen mirroring only. If your screen is off, so is Miracast. What you need is ChromeCast.

^^THIS!! A ChromeCast is what ya need!! I want one for myself too! As soon as a Best Buy within 1 hour of me gets 1 in stock, I'm going to grab it!!

Thanks guys for your replies.
I came across two apps: full!screen & ScreenStandby. I haven't tried them yet since both require the tablet to be rooted.
While in Miracast, YouTube, Netflix and MXPlayer shows in fullscreen. For others, I think the full!screen app should be enough. ScreenStandby has an option to turn of screen while mirroring. That I guess would solve my second question.

Help Can't cast ti chromecast

Just lost the ability to cast my screen to chromecast which us really annoying... Haven't really changed anything, running Cloudy 2.5, I can see the chromecast and reboot it via the app, but it doesn't show up when casting. Installed 20U and casting works so it must be something eith my rom or apps.
Anyone resolved this before or got any ideas?

Chromecast Notification not working

Hi everyone,
I'm having a very weird and annoying bug with my OnePlus 5T on OOS 4.7.5
Normally, when I start casting content to my Chromecast Audio, I get q notification on top that shows me what's going on. The same goes for all Devices on my Network. Now, with the 5T this doesn't work. My wife get's the Chromecast and Google Home Notification, but my 5T refuses to show anything. Casting works just fine, and If I open the Home app I can see the current Playback.
I've checked the relevant settings and can't see anything that might be amiss. Other apps notify correctly as far as I can tell.
Any clue what might be wrong?
Thanks!

I flashed OmniRom 8.1 and now the Cast Notification is there. The Rom is a lot slower than OOS and Camera is not fully supported, but apart from that it works just fine and doesn't have the Cast bug... weird...

[SOLVED] - Problem with built-in casting function MIUI11

Dear All,
I would really appreciate if anyone could help me here.
I have issues with casting my phone screen to a display, let alone choose the advertised options like cast with screen off.
RN8PRO MIUI 11.0.2.0 (PGGEUXM)
When I am on that cast screen and tickle the cast button to the right, it just does nothing at all.
I have seen online people doing the same thing and then it opens a pop-up at bottom of the screen and start searching for display. For me it does not, it just stays there doing nothing.
If I leave that screen and come back it is again disabled.
So my simple question has anyone managed to cast anything using that built-in function?
I can cast using apps with cast-enabled function no issue, and yes I have Miracast enabled device, yet the built-in cast function seems completely broken -or- I have disabled a service it needs to work, idk.
With the app Wireless Display for MIUI I can workaround this and cast my display at the very least, however, I dont have access to any of the cast options advertised on the cast page.
The fact it does not open the small pop-up at bottom of the screen searching for devices makes me think I have some kind of problem, either permissions too restricted on something or some needed services disabled.
Please help if you can.
Regards.

Those two services are needed for casting to work:
Mi Connect Service (com.xiaomi.mi_connect_service)
UniPlay Service (com.milink.service)
So if you debloated your phone you need those two back on and running. If they are, search for remote display happens and remote displays are found as expected.

I have the same problem in note 5 pro and Poco. I read somewhere that mi uses Miracast and it doesn't support Chromecast. Sorry if I am mistaken.

Yes that's also the information I have.
However my problem described above also concerns casting to a Miracast device. The built-in method from settings just does not do anything for me, it does not search for anything at all actually. Therefore cannot find anything either
I am surprised not more people are using casting/mirroring features of their phones, RN8Pro being such a powerfull devices it makes a very nice handcomputer.
I wonder if that built-in function works for anyone.
Regards.

The Cast option does not work for me either.
I use the Wireless display option to cast to Chromecast.
Is there a difference between these two options?

I think I found the solution or at least the source of my own problem (took me enough time...).
As I was expecting I had debloated my phone a bit too much and removed some services needed for features I am using which at that time did not look like that needed for me.
Those two services are:
Mi Connect Service (com.xiaomi.mi_connect_service)
UniPlay Service (com.milink.service)
So if you debloated your phone you need those two back on and running. If they are, search for remote display happens and remote displays are found as expected.
Once you have reenabled those two services, the cast button is again available from the quick access and working.

I know that our phone is using the MiraCast technology which google has been removed from Chromecast (it was there before) and Android starting A9. Xiaomi keeps it in MIUI that's why we still have it.
However what I am uncertain of, is how MIUI is supporting Chromecast too? From what I read you can still mirror to a Chromecast if you are willing to use the Home app.
Myself now that I got some Amazon Fire TV stick, I prefer those a lot more for the same price compared to Chromecast, simply because you can mirror your screen without having to be connected to internet, one among many things that annoyed me on Chromecast. And they used Miracast technology.
Hope this helps.

Yeah I figured this finding would be probably useful to someone. Took me about 3 months to come up with the solution out of random tbh. Strangely none seemed to experience that issue judging by the number of answers I received in that time. And I am expecting people on XDA to debloat their phones out of the box like I did, maybe they were just more cautious than me and went a bit less aggressive on the matter. idk.
Anyway I am glad my findings could help you out too!
Regards.

It has been a while since I last attempted to solve this issue.
Last I was working on this, my researches has lead me to think the resolution of the phone which is quite big, might have been too big for casting receiver devices to process smoothly. Casting receivers do not have as big of a display resolution which often is 720p max or maybe lower for some.
As a result my investigations suggested me to try lower the phone display resolution before casting.
Unfortunately I am lacking time to test my theory and see if lowering phone resolution actually improves the playback on the casting device.
Please let us know of your findings if you decide to test those hypothesis yourself.
Good Luck!

I am sorry I have not had time to do some testings myself.
All I know and noticed was while casting from apps with built-in casting feature, it worked like a charm, however as soon as I started to mirror my screen, then it was lagging too.
Back then I assumed it was because of phone resolution vs casting devices because it was way bigger than casting receiver (usually at best 720p max and even 480p for older devices), but if you are saying it does not change anything well I am running out of ideas at the moment.
You changed both the resolution and the density of the screen using the following two commands?
Code:
begonia:/ $ wm size
Physical size: 1080x2340
begonia:/ $ wm density
Physical density: 440
Those are original RN8P resolution and density, they might be both too big for casting devices to handle, idk, might require testing.
Please let us know if your findings.

Can you try debloat this UniPlay Service (com.milink.service) and try whether you are able to cast remote display?

I have the same problem. Both services are active though. MIUI 13 on redmi note 10 pro
