Hi everybody! I'll start by saying that this forum has been really useful in the last few years, so thank you to all users that keep it alive!
I just bought a new Galaxy S20, coming from a S8, and on my old phone, when I watched a HDR video (for example, on Prime Video), the blue light filter would automatically turn off and brightness would go to the max (only while playing). Now, on S20 it is no longer the case. Even if I turn off the blue light filter, brightness can be changed with no issue. That goes beyond the purpose of HDR, which needs brightness to be all the way up. In fact, I believe HDR itself is not working. I checked with my S8 side by side and the difference is pretty clear.
Why is that? Was it the same for S9 and S10, also?
I read somewhere that screen should be set to natural (or that it automatically uses natural when viewing HDR videos), but I see no difference at all. I guess that the brightness not going up is the main cue to see if HDR playback is working or not, and - in my case - it is not. Tried also Netflix, to no avail.
May you help me with this?
Thank you!

With auto-brightness turned off and brightness turned up all the way, I am seeing the brightness go down when some apps are launched and turn back up when the app is closed. I noticed this today when launching GoChat and then also saw it when launching the stock jellybean web browser. I am not sure but I think this has only been happening since the last software update (T-Mobile USA).
I wonder if others are noticing this.

Saw the same thing when I launched camera app, I am on the latest update.
One difference is that I'm on auto bright and the brightness never came back

From DisplayMate:
Since the display often uses 50 percent or more of the total Smartphone power, various display power management schemes are frequently used. The Galaxy S4 uses one innovative approach to overcome this – when Automatic Brightness is turned on, the Peak Brightness becomes significantly brighter in high ambient lighting than is possible with Manual Brightness, up to as high as 475 cd/m2, which is 34 percent higher than is possible with Manual Brightness. This is done so that users can’t permanently set the brightness to very high values, which would run down the battery quickly.From Samsung:
Samsung Adapt Display: The Galaxy S4 "learns" what you are viewing and adjusts the display's brightness accordingly. If the phone senses you are reading an article, for example, it will illuminate from a more muted brightness.

Well, I have auto-brightness, auto adjust screen tone and power saver ALL TURNED OFF, but this 'feature' persists... and as I said, this is not just during web browsing, this is also during messaging with a 3rd party app, namely GoChat, with black background theme.... this is just not a smart feature.
maybe this is taken care of in the new update. i haven't unpacked it just yet. hoping to do that over the weekend or maybe even tonight.

What you're describing sounds like how Adapt Display is supposed to work. Does the display act any differently when you enable Adapt Display?

I have the same issue. Turned everything off completely and it still happens. I posted about a week ago and some people were having the same issue.
Some people said it was adapt display on, but I have it off. Once I switched to.the CM10.1 the issue went away. I switched back to wicked Rom and I'm still getting the same problem.
Maybe a dev will eventually figure it out while building a Rom

It seems like this is a feature that cannot be disabled by the end user. This is from Anandtech's review
"On the brightness front, the SGS4 includes dynamic contrast functions that cannot be disabled and change as a function of what is being displayed. There's an "auto adjust screen tone" checkbox under display but don't let that fool you, that doesn't disable dynamic contrast, just white point."

If it really annoys you, you can always try rooting it and install CM10. I'll be a drastic change but at least you wont have to deal with Samsung's bloat
I'm wondering if anyone else is experiencing this issue or maybe i have a weird setting set on my camera.
Issue: Basically in lower lighting areas (not super dark, in a room with a few desk lamps on) the front facing camera shows a good image. Then once i start recording a video (or even in snapchat) the image is light, then after about 1 second in it darkens. it looks like someone has turned off a light in the room.
Is anyone is experiencing this or knows of any tweaks?
I have the same issue.
uncheck auto brightness from settings-display
this still is happening even with the main camera/front camera doesn't seem to be an issue with the auto brightness any other ideas?
Same here, any camera app I use presents this issue. With only low light or indoors. This is the first phone I've owned where it has done this and I'm coming off of nexus 5 and the s3 before it.
I really hope(because I am rooted/custom ROM) that this can be calibrated on a rom type of level and not permanent bc of hardware.
Same issue with Moto G Turbo Edition...
set the Anti-flicker setting to 60 Hz.
Have anyone else got a Daydream (2017) model for their Pixel 2 XL?
I have both of these, and I'm disappointed and annoyed with the setup.
Overall, it is a good setup and could work well; however I have a few issues.
- Blacks on the VR screen 'bleed/smudge' when you move. This is most noticeable when viewing a Game or Movie and it shows a large video screen (such as Netflix VR, although Netflix VR isn't work at the moment - the Virtual TV is still displayed.) When you move your head, the black smudges across the display, like it does when you're scrolling your phone in normal use under low brightness.
- The Pixel 2 XL seems to go into low brightness when connecting to the VR. This is when it's set to 'reduce blurring' in display settings. If I set it to 'reduce flicker' then the brightness is nice and bright, but the picture quality blurs when you move your head.
I've been playing around with the brightness setting, and for me, it's way too low in VR - which is causing the black bleeding/smudging issue.
I can adjust the brightness in VR mode, but it then keeps that brightness when I go back to normal use - which is annoying (it should switch back).
Has anyone else noticed this - I don't think I had this issue when I first got the phone and the VR - so not sure if I've messed too much, or one of the app updates/phone updates has changed something.
I've tried clearing the CACHE/DATA on Daydream app but that doesn't seem to make a difference.
Is anyone having issues with auto brightness, jumping up and down every few seconds? Im currently sat in a dimly lit room with the TV on and my screen keeps changing brightness levels every few seconds, if I pull down the notification area I can see the slider jumping about. I'm guessing the phone is reacting to the TV changing brightness levels as the picture changes but it seems way too sensitive.
Yeah known issue afaik. I'm hoping it gets resolved on an update

One of the fixes in the November update was "Improvements for auto-brightness response in certain lighting conditions.".
I think auto brightness has always been an issue with Pixels. Its a feature I always turn off at this point

Yeah it is up and down like a brides nighty when the light it low on mine, it isn't smooth like it was on my Pixel 5. It feels a bit like the sample rate needs a longer delay because just an increase in brightness on my TV can send my Pro brightness shooting up, the adaptive display needs to wait a few seconds before acting.

Yeah my pixel 5 and 4a 5G never had this issue (same room and lighting conditions) its crap we have to pay to be beta testers nowadays, guess we will have to wait for another "fix" in next update.

Should we really have to turn things off, considering the cost of this phone? Throw in a case and charger and your over £900 in for this phone, everything should work out of the box without having to turn off features.
It's horrible. When I sit at night in a dark room watching TV, it seems to react to the TV and jump all over the place. Never had this on a phone before. Why can't Google get auto brightness right? It's ridiculous.
Personally, I've always preferred Pixel's handling of auto-brightness to that of my recent Note 10+. I thought Samsung's auto-brightness didn't adapt very well (besides the dimmest not being as dim as the Pixel when using in the dark).
I mean, I'm absolutely confused. People started complaining about this issue back in 2019. Basically, if you turn off the Auto HDR function in the camera settings, take a photo of a lit ceiling lamp for example and then open the photo, you will immediately see the photo being processed (you can see those 4 colored dots circling) and then the highlights will be turned down before your eyes. The same thing happens when enabling Auto HDR. This function is never off and has never been off since at least the S10 series. Why is Samsung ignoring this? I've tested this on five Samsung phones. I've also spoken with their support team in a live video call and shown them the photo being processed before their eyes. They made me go to warranty with the phone but EVERY Samsung phone does this )
