I have noticed that when playing HDR videos on youtube, screen brightness automatically jumps to max. No matter if you manually change the system brightness, doesn't affect playback brightness. I have turned off adaptive brightness as well, still no dice. This only happens when you go fullscreen. Doesn't seem to change brightness if you are watching video in portrait mode or PIP mode.
Anybody else noticed this behavior or know the reason for this? As far as I know, P2XL doesn't support HDR (like LG V30 or any other device that supports it). I am on youtube 12.41.xx.
It does support HDR and it only kicks in for fullscreen youtube. The brightness is HDR, HDR is not just a wider color pallet but also controlling brightness of the areas.
Cool. Good to know. I was under the impression that P2XL doesn't support HDR as its not mentioned on product specs page on google store.

When I'm viewing videos in the standard video viewer and the Power saver is ON the brightness is too low. This started happening recently, I think after JB update.
Do you guys have the same problem? Is there a solution besides using another viewer of course?
Turn Auto-brightness off and set it at a point where comfortable for you?
I would suggest trying either MX Player or Mobo Player from the Play store both are free, and both have hardware / software support. You can control the brightness level in both apps, by swiping up and down on the left side of the screen. Hope this helps!
Hi all,
When I watch Netflix or prime everything is fine. But when I stream videos, the brightness and contrast ate too low.
Is there a way to adjust this? Adjusting the TV makes no sense because it would mess up everything else.
Any ideas?
Hello. So when watching live streams through an app called Twitch, I encounter massive screen tearing. If I set the video quality to any quality other than auto, I get what looks like a vertical sync bug, where the video doesn't line up with itself properly. I attached a screenshot for clarity. Even when I keep the video quality set to auto, the video will freak out and glitch every 30 seconds or so. I can always hear the audio smoothly, and the frames are still being updated within the fragmented video pieces I receive. Note that streaming video on any other app (Opera, YouTube) works perfectly fine, regardless of what resolution I set the videos to. I am running the final Beanstalk KitKat 4.4.4 release, and haven't had problems with Twitch videos on Lollipop, but Lollipop's instability encouraged me to roll back to KK. I've tried forcing GPU acceleration and disabling HW overlays to no avail. Any help would be greatly appreciated! Thanks!
When I'm in fullscreen/landscape, YouTube videos will sometimes play a black screen with audio only, forcing to me to exit fullscreen/landscape mode to trigger the video to play. Is this happening to anyone else? I have YouTube Red and usually have a Bluetooth audio and mouse connected when this happens.
I get this too and haven't figured out a way to fix it. When viewing stats for nerds, it reports a resolution of 0x1440 which I believe is the culprit. Switching orientation or minimizing video then remaximizing solves it. This only seems to happen when a video is launched while in landscape mode. Only happens with YouTube videos.
It also happened to me and I fixed it just clearing the data from YouTube app.
I have a Galaxy S9 Duos (Exynos) and I have an issue when viewing an HDR clip (ex YouTube) on a very dark environment - like at night, in a room with no lights.
When playing the video, the screen keeps changing brightness depending on the light coming from the clip. I suspect the brightness sensor reads some of the brightness from the screen and, as the images change in brightness, the screen brightness changes too. It happens only with HDR videos and I have no issues if I watch the video in normal or dim light, only in complete darkness.
I am wondering if any of you have experienced this?
I have the same in certain scenarios on my Exynos model.
i have the same issue - but i dont think is to do with the light in the room but with youtube app
i aslo have HDR on netflix and Amazon - and i can confirm both work OK
on you tube however it changes - flickers id say - based on whatever is displayed on the video -
so am guessing is a youtube issue
It's good to hear that I'm not the only one having this issue (so my phone is not defective) and it's even better to find that it's only on YouTube (I don't have any other HDR streaming services to test it with). That means it will probably be fixed pretty soon.

Hi,
I have a similar issue with the YouTube app on the S9+ exynos version (UK) but after the March update it didn't happen again for the same video. Although, when I compared YouTube playback with the S8. It didn't seem that HDR was enabled for the same video.
Also the native video player is also not playing back HDR video with it enabled although 'HDR' is bold in the title, identifying that it is a HDR clip. The same clip plays on the S8 with HDR enabled. I wonder why it's inactivated out of the box.
I contacted Samsung on Friday 9th March and they took my serial number and IMEI. They said they'd get back to me this week.
I'm getting this with the S9+ Snapdragon version. Doesn't seem to happen every time though. I killed the youtube app and when I watched the same HDR video again it didn't happen this time while HDR was definitely on.
Doesn't do it when watching in normal light conditions but constantly does in low light .
Same issue here...
S9 plus-US
I also have the same problem in YouTube I'm using s9 plus snapdragon version US , I usually keep the brightness about like 10 to 20% and when I enter into a HDR video and tilt my screen the brightness just goes up drastically and sometimes flickers.
The fix is placing it in cinema mode and turning off adaptive display mode whenever you watch hdr on YouTube on the s9 or s9 plus. Adaptive mode changes the brightness especially in low light when watching hdr. Also keep video enhancer on........
