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........

Is it possible to have the defy recording videos while the screen is off? I would like to document longer hikes and such and the screen is the biggest energy-consumer while doing so.
There are apps which can turn the screen black but i havent found any which let you disable the screen completely.
Whats the matter? Can it be hacked ?
Also is itpossible to record the sound through a headset-microphone while recording videos?
I would prefer using a dedicated mic as wind-noise is pretty strong while riding a bike and i think a headset-mic could work way better.
This has happened with every Non-Touchwiz based roms I have flashed.
Currently using this rom: http://forum.xda-developers.com/showthread.php?t=1989907
Is there any fix for this? I'm heading away on a trip in a few weeks and I'd rather not have flash Touchwiz just to record video at 30. I've always been a fan of stock android but this is the one bug I cannot stand. I've searched on here for weeks but never found my exact problem, hence this thread.
This happens in every camera app I can find, the image preview in both photo and video mode appears to stutter and lag. Obviously in the photo mode it doesn't matter, but the video maintains this lag and low fps into the video recording. It may even appear to be lower than 15, but I haven't measured this. The front camera appears to be unaffected however.
Regardless of the video/audio codec and resolution combination I use the problem still persists.
There's also a bug where instead of stereo audio, there is only audio in the right side. But that doesn't bother me as long as there is a fix for the fps issue.
Thanks.
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!
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.
i have seen this batted around quite a bit. Just a new unlocked 9+ and noticed bluetooth sound lag playing thru my auto head unit while watching a youtube video... i never had this on the s7 edge i also had.
Was there any resolution? Tried turning off wifi and it had no effect.
thanks!
