...and more buffering during the 4K, but starts by itself in 4K where it left off. No black screen when buffering - the picture freezes and you get the "buffering wheel". When the 4K is working what I see feels very smooth, but a bit annoying with these small buffering pauses... However, it iseems like things are improving and hopefully things will get back to watching 4K flawlessly again. ... View more

For some strange reason some the 4K videos are now starting in 4K and no buffering throughout the video. The usual 4K test movie "4 K HDR 60FPS ● Sniper Will Smith (Gemini Man) ● Dolby Vision ● Dolby Atmos " did start with buffering a few secounds into the movie clip, but when I restarted it played flawlessly in 4K ! Of course this needs to be futher tested... EDIT: It did stop once to buffer and it was hard to continue without starting at the same timestamp, but when I rewinded a few seconds back it works fine again. https://www.youtube.com/watch?v=vX2vsvdq8nw ...

I already have this new version installed. YouTube updates the app on your TV automatically. ... View more

As mentioned in this thread, I have done the following: resetting and reinstalling the YouTube app on my TV - and even reset factory setting on my TV. None worked. So that did not fix the problem. When the new January 2021 version of the YouTube app came out, it did help a little, but it did not fix it permanently - as the issue is still here. I have reported it to YouTube, and even chatted with a few YouTube service people but they did the same as Samsung, the three persons, I talked to - with two of them not understanding the problem I was addressing, and the third understood it but did not know what to do and just ended up asking me to address the problem back to Samsung.  The only real progress I have had is that I have gotten the forum moderator here to contact her tech people, and I finally got Samsung to acknowledge that this is a REAL problem and it is the TV (or the One Connect Box), and not my internet, or cables, WiFi, router, etc. It really is the TV - which is also clearly indicated in the UK forum in which there is a long thread of unhappy 2018 and older TV model owners who are not able to watch 4K on their 4K TV (mind you I have a "8K" TV....). So what you see in this thread is - with help from some other TV owners - put pressure to get the acknowledgement of the YouTube app 4K play problem. Now the next step for them is now to find out exactly what why this is so - and to be honest, It hink they have known all a long, but holding back on things (same that they did with the infamous mystery HDMI 2.1 they promised to upgrade my TV in their TV presentation on the Samsung website....).  So, I have done almost all of what you have suggested - except for the Reditt and discord community. ...

I just tested The Explorers stream app, which have 4K videos (and 8K) and the 4K videos are played flawlessly - again through their app ! It is more of a travel/nature stream. It is worth testing out on 4K TVs. I am a little unsure what kind of a codec The Explorers are using, and would like to look more into it as I heard some vauge rumours it is not the AV1 codec that the 2020  Samsung TVs have, but not the earlier models (even 8K models before 2020). I think the pre-2020 TV models have the  H.265/HEVC codec - so maybe that is something to look into in regards of the problems we are having with the YouTube app (as I know they uses the AV1-codec for the 8K videos). I did try their free 14 days premium trail, but canceled after a few videos as i was not able to find out if I was watching 4K or 8K, and I kind of  panicked when my profile was not working on that app, and their website was partly French (even though I had it on English setting), plus I had to leave my PayPal account and so on.... I might give it another shot if I find out which video are in 8K, but the problem is that there is no button on the remote to find out what resolution I am watching in some apps. Same problem with the Vimeo video stream app, as I know Vimeo also offers 8K videos, and they are actually using a more friendly codec for the pre-2020 TV models that has the 8K function. But let's not get side tracked here. We are discussing YouTube app 4K problems here in this thread, so let's stick to that. I just wanted to mention that this again proves that the 4K streams works on the TV, but it is the YouTube app that have some sort of issue that I am trying my best to find out exactly WHY this is not working properly except for through the internet browser on the TV. Now speaking about the YouTube app, it seems to go more over to 4K in periods after the new upgrade of the YouTube app - though I am stuck with the defaulting to 360p, which is actually now even happen as I write this post and this is on a 1080p video upload (worked fine when I manually changed back to 1080p), while a few hours ago, I was watching a 4K video which buffered and changed up to 4K and played that for a while (longer than before...). Just a mess....  I like to point out another forum user contacted me privately (in private message) telling me he sold his Q900RA (2018 8K TV), and changed it to the 800T I think which he was very satisfied with - but he sold his TV with a loss of what he actually paid, which I would not afford ! Plus his TV was smaller than mine, and I would have to spend a lot of energy and time on unmounting it and carrying, etc. So we need to make this work again as re-selling is not an option for many of us !!!! ...

...and we are back at endless buffering - even at 1440p (sometimes at 1080p too...). By the way, still works fine in the TV's internet browser. No buffering at all...   ... View more

Hmmm.... I might be wrong... I still notice it is a better and more "friendlier" 4K but it does happen that it defaults to 360p. After testing different videos with some defaulting / buffering - I was finally able to enjoy a whole 4K viewing of the New York video without any problems - so some sort of improvments have been made.  However, after that, while watching another video right after, it seems to be defaulting from 4K to 1440p. - and then it seems to be "fine" after manually changing up to 4K again.... but then suddenly it is back to buffering (not defalting to a lower res.), and not starting until some time (maybe a few minuttes and clicking the play button after the video has stopped by itself, and I am back to 4K... 😞 It will be interesting to see how stabile the 4K videos will appear in the next couple of days and weeks. Also, have you watched some clips that - during the video - even thought it says it is running in 4K, the picture getts really blurry and looks very low res. while still playing in "4K" ? By the way, does anyone know how to read - and what particular to look for (or monitor) when checking the "stats for nerds" function ?     (by the way, now I am not able to upload pictures to this forum - so I am linking....) ...

There is a new version of the YouTube app - web_20210106_00_RC01 - and the 4K seems to be working now without any buffering or black screen - though I do not want to say that it has now been fixed...

It seems like there is a new issue with the YouTube app on the TV... The 4K video does stop, without buffering, for a short moment, and seems to be changing between 4K and 360p .several times through the duration (with up to four minuttes in between). Again, without me doing anything manually - just having the video running - and only using the app on the TV, not through the web browser on the TV or the Google Chrome browser on my MacBook.  ...

I assume you are referring to "OP" as the "original poster" of the thread you saw this ? I would not stop updating a program. This might be a short time fix, but having the latest updated version of an app/program, etc. should have fix to the recent version. So be careful about doing stuff to your TV which might affect it badly later on. ... View more

Now the YouTube app is acting strange - different than before. It goes between 4K and 360p - but instead of buffering, the video stops (goes black) for a half-second goes to 4K and then plays flawlessly for some time and then stops and go 360p and then later back to 4K... The good thing is that it changes up to 4K, without me doing anything, but the change of resolution down to 360p and up to 4K and down... is annoying. I still have the web_20201208_00_RC04 version of the YouTube app, and T-KTM2DEUC-1310.4, BT - S - so no change in the software... The 4K videos even starts in 4K. This is why viewing YouTube videos (4K) in the YouTube app - not through web browser on the TV or through the Google Chrome on MacBook with the "casting" / "View on TV" option. ... View more

@TonyTam can you find out what year your model is from ? @ivaylos you tag by not writing the name, but choosing the name from the popup window when you only write "@".   The 4K "casting" thing you do from Google Chrome might actually be working on my TV too ! However, I need to test it more, to be sure. It feels like the TV is back in the way it was before I experienced problems with the YouTube app. It is very strange if the "casting" - or "View on my TV" - option on the Google Chrome YouTube web browser works if it picks up through the YouTube app on the Samsung TV. I just watched this in 4K without any buffering:     I hope a Samsung technician could do a proper test and respond to this, as we are not technicians. ... View more

No need to be sorry for this, as this is valuable input and definitely worth testing out more . I hope @AndreN can test this out on his 2014 and 2018 TV Samsung model. This might also bring out a point: is your Philips TV from 2018 or older ? Strangely I get both the 1440p and even 4K option when I check it with my remote control on my TV. It appears just like it is the YouTube app on my TV. The buffering is there when choosing 4K, but it appears to maybe be less... I need to test this out more, but I find it very strange I get the 1440p and 4K play - when I do the 4K and it starts to buffer the quality then comes down, but still it is in the 4K option (appears maybe in 360p. quality), then after a while when pausing a little bit it appears to be in 4K (not 360p). Have you experienced 360p. quality even though the picture setting is set in 4K (not defaulted down to 360p display setting) ? ... View more

@ivaylos  I never tried that function, but that button you have inside the red circle is visible/available and works flawlessly on my  Q900RA TV (2018-model) when I do it from my MacBook Pro (mid-2012, not Big Sur-OS) through the Google Chrome web browser and displaying it on my TV ! The picture is very clear, but I am not able to get information about the resolution options in the wheel (I only get subtitles on and off, where subs are available). I would assume the resolution is 1080p. since that is the max through AirPlay ?      Notice the wheel option only available for subs on/off... Great question by the way ! I did not know about that function. This would be much easier to manover, and I am not experiencing any buffering, but a steady flawless 1080p AirPlay. By the way, what TV (and year model) do you have ? ... View more

@TonyTam Thank you for confirming that you have the same problem. Where in the world are you located ?   I find myself often using the app with a lower resolution as the web browser is too difficult to maneuver, and I do not watch too many of the DayZ gameplay videos which I used to watch daily. So this is actually even changing my behavior and it is totally unacceptable ! ... View more

This is great work Elin ! Thank you so much for getting this acknowledge by Samsung ! This is how I think this should be dealt with, but actually acknowledging the problem, and by Samsung actually using qualified technical people to find out why this happened and how to solve this. It would be a service they should be interested in finding out too, and it is about being a team player. I see that I have "T-KTM2DEUC-1310.4 , BT - S" - which I assume is the latest 1310.4 version, and when a new version is available this function will not be inactive ? It is really good to know that the YouTube app updates by itself also. It is a bit confusing with some updates (or upgrades) that are done directly in the TV, while others you need a USB stick. I haven't got that USB stick, and I see there was a new update thing available through the USB stick, but I assume they are not important. Again Elin: GREAT work ! Merry Christmas ! By the  way, I got my TP-Link Media Switch today. I am not sure I will unpack and install it now, but it might be a good thing to have everything through cable. It will make the internet connection more stable, and maybe it is even a healthy factor in there... ... View more

Just putting this information in here, which I wrote in the other YouTube error  thread, in case it has some importance: When I go to the "Apps" and click on the installed YouTube, it says I have "2.1.486" - while a friend of mine (who does not have any problems with 4K YouTube on the TV's app on his 2019 and 2020 top model TVs) - he has "2.1.493" !  It said "Updated: 18.12.2020" which was the date I did the TV reset. if you open the YouTube app, and look at app version, it said before I reset the YouTube app and reset my TV: "App Version: web_20201208_00_RC01" and afterward it said "web_20201208_00_RC04"... ...

Let me also add, that I use a lot of time, energy and effort just in the writing of these posts. Even sometimes it is a bit uncomfortable writing criticism (which are well-meant by the way !). I often even sensor myself for not being too hard or pushy, but when things are not going forward, but rather backward, then I need to voice that this is NOT acceptable as you are wasting so much of my time and energy !   Again: I am on your team: I really want us to succeed and find a solution that will solve this problem, and I want to find out exactly why the YouTube app has a 4K and 1440p play problem for my and other's TV. Of course, I would even take criticism if there was or is something I am doing wrong. So let us be very constructive and thoroughly work our way through this. If I am asking the wrong questions or not voicing something clearly then let me know. But please do not pick out only a small part of my posts and reply only to that...... That is the worse thing that the customer service and front line personnel have a tendency to do. ... View more

@ElinH I am only giving you constructive feedback which I hope you take to heart. It is agonizing for me to have a problem that affects me many times during the day. Also bear in mind that I am honestly sharing my discoveries that you and Samsung can use in the future with similar problems - and tips like watching 4K in the TVs internet browser, which strangely works. Don't forget that I am on your team. I am not doing this just for myself, but by shearing and writing all this to other customers and Samsung - and bear in mind that this is really quite a time consuming effort for me. I am using hours, days, weeks.......   So what is important is that you and Samsung follow me up 100% - which you haven't. AGAIN: I have asked unanswered questions in this thread, even asked a very easy question about why my TV suddenly has the inactive update, which you even ignored ! COME ON !!! Do I have to serve you these questions on a plate ? I told you to get up to speed here.  ... View more

Hello @ElinH I am still getting the "494 Error" when I access the forum. But that is not of my interest now. You keep on telling me that you do not have this reported as a problem as of yet - yet you see another Norwegian guy confirming this who is trying to get through the customer support without success and when he gets through they do not report the problem nor do they help - other than blaming YouTube - and you have the people in the 11-pages thread and the article I have both linked. Yet you insist on this not being a "reported problem as of yet" when all you have to do is look at this as reported problems. The suggested recommendations to give me, are something I have already done ! Why do you do that ? I have even repeated it several times in my posts. By the way, after I did the recent factory reset of my TV a few days ago to try to solve this YouTube app problem, I am back on the 1310 - not 1310.4 that I was before the rest - and the update has become inactive and "This function is not available", so I need to know how to get back to get the software/firmware updates automatically up and running on my TV and the 1310.4 version.     I am sorry to be so blunt, but you are touching surface stuff and you are way behind when you tell me stuff that I have already done - and all you do is just repeat what I have already told you, and I really do not think you are "constantly in touch with the technician about this problem" as you are contradicting yourself by insisting there are no reported registered. I do not mean to be rude, I am just being very honest that you need to pick up the speed and actually responding to what I have ready written and react to that - instead of going backward and in a very slow phase...   ...
