After updating to the latest firmware, youtube now has issues.
Before I had no issues whatsoever playing 4K60fps videos with a network connection of over 100,000 kbps and a healthy buffer....now it's constant loading and defaulting to 360P.
Same for me, on 1310.4 firmware and Samsung 55" Q6FN model.
YouTube video with a 1080p resolution and enabled "stats for nerds". At least in my case on the "connection speed" it shows 50+Mbps and on the "buffer health" it shows +60 seconds. But when I change it to 4k, everything stops, connection speed goes to 0, buffer health goes to 0, network activity goes to 0.
The last Samsung firmware broke the YouTube app, I have zero issues with Netflix, Apple TV, Amazon Prime Video.
I am on 200 Mbps connection and can confirm this buffer drop issue since late November. 4K 60 FPS is just stuck at buffering for most of the time. However plays fine in the browser.
Interestingly there is no response from @samsung978531@Support on this and an acknowledgement that this is even an issue. In the back probably both Google and Samsung are haggling on who fixes it. Make the code open source and let us do the stuff if you can't fix it.
The silence from both Samsung and Google is deafening. They could at the very least acknowledge the issue and say that they are investigating. That's not too much to ask.
In the meantime, on every video that fails to play properly, I have been sending feedback and choosing either "Buffering" or "Video is poor quality". If everyone does this, and it actually does send feedback to them, then Google should be bombarded with feedback and it might get someone to pull their finger out.
I have a un55nu7400 and have the same problem playing YouTube content at 1080p and above. Buffers for ever, no connection activity and automatically sets quality to 320p. I'm on a 200 mbps internet connection.
