I have a Samsung Galaxy S6, and also a Samsung Smart TV (IIRC, the model is UE43H6400).
Anyway, in the past, I could instantly cast YouTube from my phone to my TV without having to access the hub. However, for the past week, I no longer get the cast icon appear in YouTube. I actually now have to load the Smart Hub, start up the YouTube app and then cast. Annoying as hell TBH.
Any ideas what may have caused this?
Have started having the same issue casting from my iPhone to 2020 TU7000 55" Smart TV. The TV is only a couple of weeks old and
was working fine until yesterday. The only thing I recall doing is rebooting my router to sort out slow Wi-fi speed.
Tried everything - It just won't cast from YouTube, Netflix etc
So I recently went in to add an app on the TV and received a message about not having enough space. I deleted a number of apps and I have noticed that the option to cast seems to be available again on a consistent basis. I wonder if some update of the TV was incomplete while the space was limited. Keeping my fingers crossed that it's been fixed. It's worth a try if you are having problems.
Using Smart Things or Smart View I can cast to my old Samsung smart TV (7yrs) anything that is on my Samsung mobile.
On my newer Samsung TV about 3years old I can cast EVERYTHING from my moble, ie Youtube, Tic Tok.
Using an app called 'Play to Samsung', I can cast youtube to the old TV but its only one Youtube at a time, wheras on the new TV you tube will just run & run.
Then it should be available to cast to. Odd.
Maybe I should mention there is a work around.
I use a very good casting app called Web video caster. It can practically cast from any source including YouTube.
You can also install the Web video caster receiver via the app store on the Tv.
Once the receiver is set up you can simply open the app and then cast to it from your other device using Web video caster.
You could open YouTube via the inbuilt browser and then cast it. Alternatively from the YouTube app select share instead of the cast icon and select Web video caster.
In fact any source you want to cast just select share.
Work arounds are great in theory. Thing is, I could also plug in a Chromecast to achieve the same result... However I purchased a device based on specific capabilities... and those abilities are not functioning... It doesn't make for an overly satisfying experience
