I recently got a Galaxy S5 and realized that it's one of devices allowed to cast its screen to Chromecast. I installed the lastest ChromeCast app on my rooted S5 running stock Android 4.4.2 and as expected the Cast Screen option on the Chromecast app was available. My Chromecast dongle is running firmware 19084 and both the S5 and the Chromecast dongle are connected to the same SSID in my wireless network. My S5 is rooted, but my Chromecast dongle is not. I'm able to cast content from the Youtube App and other apps from the S5 and from other devices in my LAN without any issues. I just can't get the Screen Cast function of my S5 to work. I keep getting a toast notification that reads "Casting screen to (Chromecastname) has ended" every time I press the Cast Screen button.. After pressing Cast Screen in the S5 the screen of TV sometimes goes black, but during other attempts the Chromecast screen saver remains. I have factory reset and reconfigured the Chromecast dongle, uninstalled and re-installed the app, and cleared the data for the apps as suggested in other forums, but no dice. Given that my old rooted Galaxy S3 is not listed as a supported device, I decided to modify it and use it for testing. I installed #MirrowEnabler V6 (Experimental) to enable the Screen Cast option in the Chromecast App on the S3. The enabler activates the option, but when I try Screen Cast it fails with the same subject error. Is Screen Cast supported from rooted devices? I also have a couple Xposed Framework modules installed, can one of these be causing the problem? What Am I missing?
I have the same problem I'm trying to cast from an LG g2and I have the exact same sympton hope the one you described.
I'm running Android 4.4.2 also my device is rooted but the chromecast is not.

Those symptoms can be caused by poor WiFi reception on the Chromecast. I get the same on my CCs that have weak signal.
"Optimized" streaming services/applications like YouTube, can compensate for a slow connection by switching to a lower-bandwidth version of the stream. Screen-casting, however, runs at a high rate, and if your Chromecast's connection can't maintain that rate, you'll get black screens, frozen playback, image breakup, drops back to the backdrop/wallpaper, and even temporary Chromecast disconnect.
speed4cast can help you measure the connection speed, so you can try different things like using an HDMI extender (recommended), other HDMI ports, reorienting/repositioning your router, or using a 2.4GHz WiFi extender/repeater.

Thanks for pointing me to that Chromecast speed measuring tool... I'm about to install it on my SGS5 to test. In terms of performance, what are the recommended speed ranges for Download and Upload for "optimal" Screen-casting from a mobile device connected to the same wireless LAN as the Chromecast? My Chromescast is very close to my Netgear N900 router, but it's connected to a HDMI port on the back of the TV.
My CC that works well for screen casting is reporting 8 Mbps down, 4 Mbps up.
Another CC that's working fairly well for screen casing is reporting 7 Mbps down, 2 Mbps up.
My CC that does what you describes and pretty much can't screen cast except for a few stills is reporting 1.75 Mbps down and 1 Mbps up.
Today it seems to be screen casting without dropping off, but it's choppy and blocky at times. In the past I've had it do what you describe, but I think my repeater wasn't online then. I'd try disabling my repeater but it's in a difficult-to-access location.

Now I think I get it... maybe? When I cast the screen from a mobile device from the LAN the casting still depends on the download/upload speeds of my Internet connection to/from the CC. Just like regular casting from say... youtube. Even while the screen cast content is coming from mobile device connected to the LAN to a Chromecast dongle connected to the same LAN... the screen cast content is also routed via the Internet? Am I making the right assumption here?

The data isn't routed through the Internet, but the quality of wireless connection between your Chromecast and other devices like your router is critical. I'm not sure if it's different in other scenarios but with my S5 and Chromecast both connected to the same router the data does seem to go through the router, rather than WiFi Direct like Miracast.

I believe the quality of the connections and the performance of my wireless LAN is good. The speed4cast tools appears to measure "Internet" connection speed... not WiFi connection speed. It appears to measure the speed performance from either the Android mobile device and the CC or the CC and the Internet. The performance when I stream HD media to/from all my other wireless devices is fine. I made sure to turn off all the other wireless devices when I was testing the CC with speed4cast and when I attempt to cast the screen of my SGS5. My LAN wireless speed is more than adequate. Copying files from my WiFi connected laptop to my wired attached NAS averages 25-35MB/s. The upload speed to the Internet is low... about 1MB, but my down speed is about 10MB. My SGS5 works fine with all other devices on my LAN while connected to the 5,0GHz side of my router. I even tried connecting the SGS5 to the 2.4GHz side of the router where the CC is also connected, but this made no difference. My wireless connected laptop, Vudu Box and Samsung Smart TV play HD streams from the Internet without any issues. I can also stream HD (1080i) YouTube videos from the SGS5 or laptop to the CC without a glitch. If the SGS5 Screen Cast media stream or control protocol(s) aren't being routed through the Internet then something else has to be at play here because the only bottleneck I can identify in my network is the 1MB Internet upload speed.

Yes, speed4cast measures the speed between Chromecast and the Internet, but you cannot measure the Internet connection speed independently from the wireless connection on Chromecast, because the Internet traffic is flowing through the wireless connection.
So, if the reported upload/download speed is anything LESS than your Internet connection speed, then the Wireless connection* is slowing things down and the reported Internet connection speed is really your wireless connection speed.
For example, I have 50 Mbps down, 20 Mbps up. If I do an Internet speed test on a computer, I see 40+ Mbps down speed.
Yet, my Chromecast is only 8 Mbps down?
If I do the same test on my phone connected at 2.4 GHz I get much better results.
So, the wireless connection between the router and my Chromecast is limiting its transfer speed.
* if your wireless AP is not your router or there are other network segments between the Internet connection and the AP, they may be causing the slowdown instead of the WiFi connection. Also, if your router/AP is slow, the wireless devices may be connected at a high rate, but transfer to/from will never reach the maximum because the router/AP is slowing things down.
Checking the wireless speeds on your other devices doesn't mean anything because those other devices are not where your Chromecast. The closest you can get is maybe to put your phone/tablet as where Chromecast is, which is usually right up against the back of the TV. You're almost guaranteed to notice the speed will drop significantly.
As I mentioned earlier, tests with dedicated streaming video services like YouTube, Hulu, etc will not give you an idea of your wireless transfer speed unless they provide visual feedback for the connection quality.
They are designed to transparently handle a wide range of connection speeds, unlike screen casting which essentially says "I need this much bandwidth, or it's not going to work correctly."
If you have Netflix, you can try their speed test video.
This article talks about it. Note that on my Chromecasts with optimal wireless, I get up to 5300 kbps which appears to be the max.
On suboptimal wireless I get far less.
http://www.wired.com/2014/06/netflix-streaming-test/
Given your other devices have good WiFi performance, at least we can rule out your router slowing things down.
Your phone may be able to send data to the AP very quickly, but if Chromecast cannot receive that data fast enough because it has a poor wireless connection, then that doesn't help.
The data flow for screen casting is this:
Phone/Tablet <--A--> AP/router <--B--> Chromecast
Segment A is great, but segment B is what is suspect. Only hard numbers will tell.
speed4cast measures
Internet <--C--> AP/router <--B--> Chromecast
And you've already said your Internet speed is more than adequate (it should be unless you're on public/hotel connection, dialup, ISDN or repeating another WiFi connection).
B is the common part, and eliminating C, speed4cast will give us a measurement of B.
So run speed4cast on your Chromecast and tell us what it says on the screen.
If it confirms that your Chromecast has a good bandwidth connection, then it's something else in play. But in most cases interference from the TV makes Chromecast have less than optimal wireless speeds, and that's why you see some people complaining about streaming quality, because the streaming server is downgrading the bitrate (and hence quality) to compensate.
Screen casting doesn't do that, so if your Chromecast's wireless connection can't sustain the required speed you'll get blockiness, low framerate, jumps, or disconnection.

I could be wrong, but I still believe that "something" is being routed (uploaded) to the Internet and down to the CC. I guess I was not clear before, but the up/down speeds that I posted (1MB up -10MB down) were the numbers that the speed4cast tool reported from the CC. That's the reason I suspected the up link to the Internet was causing the problem in the first place as those numbers are the same numbers I get when I run Internet speed test from my laptop and from any mobile devices connected via WiFi. Intel PROSet also reports excellent signal quality (300.0 Mbps) when I put my laptop next to the CC. If I put my old SGS3 right next to the CC behind the TV... I can stream HD video using UPNP/DLNA media server and client in both directions while connected to the wireless network via the same AP of the router. I get no blockiness, low framerate, jumps or disconnection when streaming to/from my SGS5 to my SGS3. So, the wireless connection in segment B is fine (router <--B-- > CC). If there was a WiFi connectivity issue in this specific segment then I would experience the blockiness, low framerate, jumps and disconnection when streaming HD video to the CC using the Youtube app from my SGS5. There are no other network segments only one Router with 4 Gig Ports connected to devices that I turn off along with all the other devices that are connected via WiFi to avoid any conflicts/interference during my test.
Ah okay.
I don't think there's communication beyond downloading whatever bits are required for screen casting (the app itself).
And if your other devices are reporting the same up speed then your CC doesn't sound like it's being hampered by the wireless connection itself.
What carrier is your S5? Mine is AT&T and works well.
Is your native screen mirroring enabled? (Mine is)
In some cases it can enable/disable things that help or hurt the Chromecast mirroring.
Screen Casting now works with the new Chromecast App (v1.9.7) on my Nexus 7 running Lollipop 5.0.1. The N7 used to give me the same casting has ended error with prior versions of the app. But... it works fine until you want to disconnect from the casting session. I can not disconnect or try exiting the the app without hanging the N7. Oh well... This function is not mission critical for me anyway.
I still get the casting has ended error from my SGS5 and SGS3 using the same version of the app on KitKat 4.4.2. I guess now I can say with a high degree of certainty that the issue is not with my LAN setup or WiFi performance. There's still something else at play. I few days ago I noticed that the latest version of Speed4Cast (1.02) did not work with any of my devices. Once I updated Google Play Services to version 6.5.99 Speed4Cast started working again on all my devices. I think some authentication needs to happen between the casting device and some Google server... when this connection/authentication fails or is flaky there are issues casting the screen from the device.
I cannot cast anything without it buffering on my chromecast anymore.
Youtube/Netflix can play but resolution is of lowest quality (probably because its built in), but casting tab from web browser will not work at all. At first I thought my internet speed was slow, but I do a speed test most days (on mac) and get an average of 30mpbs-35mbps. Mobile speed I get is 5mbps. Funnily enough I play Netflix through phone and it plays but like I said, quality is compromised. My other tv which is a smart tv (no Chromecast) plays Netflix/Youtube of the full 1080p and no lagging. So which leads me to believe that there is a problem with the Chromecast itself?
My only other option is to see if it works on the smart tv, but then it defeats the purpose of having a smart tv. And I will be without smart tv/chromecast in the bedroom.
Any advice please?
yep, I'm finding this too. I ended up hooking my laptop up via hdmi because casting was so poor. Really low resolution and it would lose connection (black tv screen, laptop still playing) for 3-4 seconds, every 15 minutes or so.
I'm very quickly losing patience with the CC.
After 3 chromecast (of which 1 returned) and trying 2 new routers specifically for making cc work I couldn't find any permanent solution. Where any phone or tablet works fine for streaming netflix, plex, etc, cc would struggle, I gave up, it's useless. Btw, the routers I tried for the past year are netgear r6200, Linksys ea6500 and currently netgear r7000.

Do you try speed4cast? You can see if the problem is from internet or from CC. Reboot router, enable upnp on the router and look for new update by rebooting CC.
If nothing works, make a factory reset and try to cast. If not, return the device.
Trying to set up something in my camper so that I can watch downloaded movies or shows from my phones. I have a Note 3 with android 5.0.2 and miracast seems to be broken? When the Note 3 had 4.4 it worked fine and I used a Sony dvd player that it worked with just fine. It "sees" the player but won't cast to it.
I have a Google Pixel XL that does not see the dvd player for some reason. I brought a wifi router into the camper and tried to set up a chromecast (Gen 1). I can get it set up but then neither device, when connected to same wifi, see the device so that I can cast to it. I am going to grab a Gen 2 model from home and see if this will work.
Is there a simpler way to make this work? It was so easy just using miracast and now this has turned into a massive headache.
If you have the Stock FW on the CC, please ensure, that guest mode is enabled (via Google home). In this case the CC provided an own Wifi net if needed.

I've never been able to get the guest mode to work. It seems like no matter what the chromecast still needs an actual internet connection, even if only casting a movie/picture right from device.
So far what works for me but it's annoying. I have my actual Verizon phone turned on as hotspot, Set up the chromecast to connect to hotspot. I leave it up and running. My Note 3 has my movies on it so I connect to same hotspot and cast using Allcast app...I think. That's the only app that even seems to find the chromecast. Yes I have Google Home installed on both devices. If I turn off the hotspot Chromecast stops working. Neither device finds the chromecast after that unless I turn hotspot back on. Yes guest mode is turned on. A pin is never displayed but since devices don't see it it won't help anyway.
I had a spare wifi router and did the same test. Still need an actual data connection. If no data connection the devices do not see the Chromecast.
Technology is really frustrating at times. Miracast worked just fine until Google didn't like it and made the Chromecast. The Note 3 is old and close to being dead so I am not buying a MHL adapter for it nor will I buy a new tv that has something built in that does not seems to work either. Many other camping people are starting to run into this issue as well.
if you go in Google Home under your device, Settings, there is a possibility to switch the guest mode on. This means the CC works like a hot spot. Its written also on the screen. Every device, which is not in your network, could get an access. I don't know, at which time the guest mode will be disabled automatically. Maybe at this time, if you stream something over your own network to the CC.
Hi,
I bought a cheap "MiraCast" dongle from eBay that works great. Less than $14 with shipping included from China. They list them as a "2nd Generation Chromecast 2" screen mirroring devices, a little misleading, but I'm happy with the unit, as it was brand new, in a very nice box I might add. If you need a link, then PM me, or reply here.
PS, they picture a Chromecast shape, but the lead with a Wi-Fi antenna is a giveaway. Here is a link to get you started, and actually is titled better than the one I bought, which is sold out. There are lots more like it at varying prices. https://m.ebay.com/itm/2-Digital-HD...d=202018167243&_trksid=p2349624.c100408.m2460
Motorhome option to cast from phone or tablet or TV without Wi-Fi or hotspot connecti
I was looking at a thread that discuss different connectivity options without Wi-Fi but could not figure it out. Are there any updates to this? Right now the only results that I have is to hardwire an iPhone to the TV using the HDMI connection and Apple Adapter device. The Mira cast Dongle works most of the time but is intermittent at best.
My son upgraded to an iphone so I got his old S7. Using it and the sony dvd player I can use miracast again.
I have also set up my main phone as a wifi hotspot and connected a chromecast and my S7 to it as well and been able to cast. This method ties up both devices and then they also both need to be plugged in. My wifes Iphone can also cast to the chromecast when connected to my hotspot.
Best I can come up with for now.
