I also realized yesterday my S21U was brighter when I watch HDR videos in UKposts. Since I almost never watch HDR videos, I didn't focus on it. Nice work.

My main issue with the S23 Ultra was its HDR performance and how it handle bright scenes. And brightness changes are visible. For instance if suddenly a bright scene came then display will start adjusting brightness instead of it being seamless. I wanted to try S24 Ultra display because I hoped they would have fixed the issue and in S23 Ultra I checked for this change on every monthly updates.

Thanks for raising this issue, it’s an actual issue on most android phones, especially ones without Dolby Vision. You have manually put brightness to max in hdr content most of the time in most android phones

Isn't there an option in the UKposts app to force the brightness to maximum for HDR videos? Also, Samsung should let their ego down and give Dolby Vision on all their devices, even cheap Xiaomi phones come with Dolby Vision displays nowadays.

It's sad that all the big you tubers don't even mention this

I noticed something was a bit weird when I switched to my new Galaxy S24 Ultra from a Galaxy S21. I absolutely love this phone, but HDR was weird. I also noticed it would dim more than I was used to in indoor situations, whether watching videos or just using the phone. I find myself reaching for the brightness slider. This is a bummer, I hope Samsung adjust it to work better. Choosing a phone requires waying the pros and cons of a given device. No phone is perfect. Samsung get so much of the other stuff right on the Galaxy S24 Ultra that I do not regret my purchase.

Wow it's still broken? Glad I returned my s24 Ultra purchased at launch. Finally someone from the tech media talked about this defect.

Great information ❤ thank you 🙏

Yes its true HDR issue is there in S24 Ultra and not only its specific in S24 ultra previously i was using S22 Ultra it has the same issue also my friend has S23 ultra the issue exist if u go on dark the brightness gets dimmed u cant even see anything whether its Netflix, Prime videos or hotstar for the same issue i want to samsung service centre wrote many such issue to UKpostsrs but nobody said anything also nobody is highlighting such thing i am glad u raised this issue.

I've noticed when recording video on the S24 ultra HDR10+ is really dark and colors are way off. It worked perfectly out of the box, but the recent camera update did some damage

In a lot of HDR dark scenes, the s24 seems to have a black/grey crush, the step shade is so harsh. This reminds me of the Galaxy Note 2's black crush. A great example of this is the 4k hdr batman lougne fight scene in about 17seconds. Dim areas are bright grey. Does not happen on my note 10+, s22 ultra and on my oled tv

My S24 Ultra isn't using HDR either.. I was looking at things on UKposts that should be HDR and it's really dim.. with no option to access video quality on the screen. Which I can normally access.. really weird and odd for a flagship. And im very confident that my S22 Plus was brighter alot brighter.. im almost positive it was.

It seems like a thing with a lot of other Samsung phones/tablets as well. I have the S20+, S22 Ultra, S24 Ultra, and Tab S8. HDR used to be the brightest on the S20+. After a few updates, it no longer looks bright enough. The S22 Ultra and Tab S8 had poor HDR from the start. Right now, the S24 Ultra looks slightly better than the others, but not as good as the S20+ was before Samsung messed it up with an update.

HDR has always been broken on Galaxy. One of the reasons I switched to Pixel.

Parabéns Carlos. Merecido. O algoritmo pode não ter ajudado muito o teu canal, mas é bom ver-te aqui

Welcome Carlos!

Great video!!! Did you notice color banding on s24 ultra?

I think video playback is also broken on my 13 pro it gets really dark during high action scenes on ott platforms

I have a S22 Ultra and I noticed it with mine, I believe it's definitely software related. The hardware can handle it, my guess would be they are trying to balance performance with battery consumption. Just my opinion 🙂

Is the adaptive colour tone on?

Are you sure you don't have "Extra Dim" enabled in the quick settings?

And another question. Do youtube need to be open full screen to engage HDR? In a normal mode does S24 tonemap content to SDR to match non HDR content?

I though the problem could have been resolved with the video brightness option. When you select it to bright, it is supposed to make it appear better. But if it is an ongoing issue, then i guest Samsung should fix it.

Thank you for sharing. I also don't like this behavior, any automatic change in brightness always takes me out of what I'm watching, completely breaking immersiveness. I don't understand how they come to the conclusion that it's better for immersion, maybe I'm the weird one. I can never agree with not giving the user the choice.

They need to fix this ASAP!

This auto brightness issue with hdr content is same in s22 ultra,s23 ultra also, to check 'put torch on ambient sensor near front camera on hdr videos' , you will see more bright image.

Thanks for making this one...

I HATE this stupid company. They are cutting corners even on their TVs by not specifying what display you will be getting on their premium TVs

I think is effect from anti reflective glass, because the glass is more dark than before

This video is all over the place 😅. The vivid update made my s24U look more vivid than my S23U which was not expected. I don't see any screen grain. I do think some markets may have got defective units coupled with scuttlebutt online the issue is exaggerated

Suttlety of the jabs you take without destroying the products is masterful. Bruh you got this, continued success. We'll be watching 😉

Can you say if s24 show HDR in Instagram? S22 seems do tonemap both video and photo. Iphone 13 show reels in HDR. And i am checking with friends if photos are supported on iphones. S22 seems abke to play only youtube.

Write these issues on samsung community. Does it happen for downloaded content as well ?

I turned adaptive brightness and color tone off, and extra brightness on. Seemed help make the colors pop a little better

Yes people are going out on sunny day to watch movies on phons 🤦‍♂️

Hdr not working in Netflix app? Tap on screen when content is playing, you'll see a brightness slider on the left, drag it all the way up and then back to half way..... Seems to fix my problem of Hdr content not playing right on Netflix. Cheers.

I don't get it. At the end the opinion is that Samsung wants to make the image more and more bright but earlier it talks about the video becoming less bright. Also if Adaptive Brightness is bad and the issue, wouldn't it "off" be similar to a "Filmmaker on"? It's even in the quick settings for brightness. So personally I think I'd keep it on as the majority of my time is spent with changing lighting conditions (and I want to see in sunlight, or not get blinded when I'm inside). The time I watch a movie for 1 hour+ straight I'll just flick that switch.

Did you notice colour banding or grainy texture (or mura effect) on your screen?

All the s24 ultra's have so many screen issue at the beginning vividness was the problem and nowadays grainy/sandy display which becomes worldwide recently and now you mentioned broken HDR. Samsung latest flagship which is one of the most expensive phones :)) and the point is Samsung makes all the OLED displays even for other brands like Xiaomi or iphone but they're flawless and unfortunately its own phones have so many issues. Why it should be like that? Even they don't care for costumers, they ought to respect people and Samsung users.

Did you set the extra brightness for videos in the settings?

I recorded HDR10+ on my new Galaxy s24Ultra and when i saw it on Facebook the colours are super overexposed and very off and just weird. Makes me kinda sad. The phone costs a fortune 💸💵

I noticed this issue too on my S23U when I first got the phone last year. But it wasn't until in December 2023 that work provided me with an old iPhone 12. At first, I was shocked that more often than not, I preferred consuming any sort of media (YT, Netflix, TikTok, IG, etc.) on my work phone, despite the smaller, non-OLED panel. I couldn't quite put my finger on it, but to my eye, it just seemed like my brand-spanking new S23U's display wasn't as bright/colorful/beautiful to look at, compared to a 4-year old panel!!! And even when I compared it to my previous phone, the N10+, I still more often than not preferred the image/media on my N10+ than on my S23U. Thank you for figuring out the issue. Hope Samsung in the future would push an update like the FilmMaker mode you suggested. It really throws me off that supposedly Samsung S series should have the best display panels, but not always the best viewing experience. Real shame.

I believe and if i m not wrong you have not used video brighteness mode which is available in advance features which enhance video picture quality. Because it is available in S23 series phones so same feature available on S24 series as well. In this u have not shown that you used that functionality.

Thank you for pointing this out. I hope this issue is escalated so that Samsung issues a fix.

yeah samsung screen quality is down, compared to my old a71 the new a73 screen looks washed out white.

It’s a Samsung, what do you expect?

I think it has something to do with the Snapdragon gen 3 chip because every phone that I have with the Snapdragon gen 3 chip it has a dim display. But my xiaomi 13t pro HDR content looks amazing. So disappointing. Phone is to expensive to over look. Just got my ultra. I think I'll return it.

Switched back to my 15 pro max sadly. The 24 ultra is great when it comes to the camera very inconsistent especially at night. Taking video of my kid the ultra has noise even in with bright light vs the iPhone. Wish Samsung would just have a great that works right outside the box… waiting

I guess DXOMARK was wrong to give it the highest display rating! If you say so

So this is basically just one of the granules of ice that is the tip of the iceberg that is Samsung devices, my biggest gripe is that cell phone carriers do not offer anything higher than 256 or 512 gigabyte models. I went through 512 gigs on my s23 in 5 months. Since then I've been teetering around 10 gigs of space every other day. Thankfully I'm a phone hoarder and I can experiment on what apps I want to keep on my Note 10 while I try to get my stuff together on my 23 before I pick up my 24 Ultra. But here's the real issue now companies are mandating that user privacy data is no longer going to be stored in the cloud and it's going to be stored on the user's phone. I wonder how long it's going to take before 1 terabyte becomes the basic standard because our phones are going to be full of our own stuff. I understand the whole privacy concern but that's only because people are overly concerned about their privacy, which in some cases they should be, but if you're doing it right, you shouldn't be and you should opt out of in device storage. I'm looking at you Google

Yupe, I noticed this, too.

When i viewed halo episode 4 in hdr (by accident), OMG was it bad. I had to watch it in SDR in order to see the dark environments

I am pretty certain that this screen problem showing HDR content, is also to do with the anti-reflective covering on the screen which of course is now completely flat, unlike the Samsung galaxy s23 ultra which has a slight curve. I have heard many people talking about this. The flat screen now being of course anti-reflective in my opinion has absolutely ruined Samsung's reputation for great screens. The S23 ultra is far better, far brighter, much more deeply saturated and much better suited to HDR content when it does not alter the particular brightness or saturation levels due to the ambient light situation that may be in in any given moment in time. Because the S23 ultra doesn't have the anti-reflective screen coating like the s24 ultra does, in my opinion it is far more immersive and a much better screen experience. I have the Samsung galaxy S21 ultra at the moment, however, I am going to upgrade to the S23 ultra. I am going to give the s24 ultra a complete miss. Yes the S24 ultra has the Qualcomm 8 gen 3 processor - and the S23 ultra has the 8 Gen 2, but in a real life scenario it makes very little difference unless you're an absolute tech nerd. They have taken the optical zoom down to ten times in the galaxy S23 ultra to five times in the Samsung galaxy s24 ultra as well. So saying all of this, in my humble opinion the s24 ultra apart from the processor is a downgrade. All of the ridiculous hype about the AI capability will only be freely available until 2025, and subsequently at that particular time, we will have to purchase that from Samsung. My mind is made up now, I am definitely going to get the s23 ultra as an upgrade to my S21 ultra. Thank you for your videos, and keep up the great work. Subscribed. 👏...

The grainy display issue or mura effect spoiled this beautiful stuff...experts are attributing this to be a hardware problem.

That display is not that good like you say. For that price and they still uses a 8 bit screen 😂

My Note 9 HDR (and Dolby Vision) looks better than my S24 Ultra. But I have to say, outdoors is another thing.

Guys in Instagram it happens constantly, this is the most broken feature I've seen, I'll be selling my S24U because of this, and other multiple deal breaking quirks that affect my workflow.

Turn off ambient mode on UKposts

Adaptive brightness should always be turned off, more junk software....

Woww. Why do you have your display Soo low.. that's why your video HDR is low. Blast the display bar to the max. SMH

Great on my Sony Xperia 1 v 😊

I just played an HDR video on my S24 Ultra on UKposts. HDR seems to be working perfectly fine.

Crazy. This phone is supposed to be the to of the line just to see that it doesn't perform better than my other phone that's half the price. I'm returning mine

I don’t need to care about this, but it is something I would love to know about. Thanks for the video.

A lot of noise in this video?

i lovr my S24 Ultra and i never have any issues and it still works for me!!🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣

Samsung messes with everything. That's why i never bought anything Android related from them. They are a pain for any developer because nothing works as intended on them. Bluetooth, power saving settings, background app termination, display. They are this way since forever. I really never got why people buy that crap.

First & Best Video ✌️

It's also probably bc of the anti reflectove screen

Been the opposite for me S24 Ultra display in HDR on UKposts was incredible.

I gave up on Samsung after 7 years of using only their flagships. Even without considering the price, it's just too many compromises. I mean, display has issues. Camera software is terrible. One UI isn't as polished as it could be. Vibration is too soft and weak. Speakers are worse compared even to older Samsung devices. You spend your time waiting and hoping for updates that will magically fix everything (does not happen) and right before you know it - it's time for new model to be presented and more then often, "old" (last years) one is crippled with software updates. I hope that "I'm fine with my device" users will become more demanding in future.

S24 ultra looks like downgrade to me. 10x gone, curved screen gone looks like normal phone. Thats y didnt switched, s23 ultra is already 2 years ahead with processor and camera quality still feels better than s24 ultra.

Even it's broken it's still an amazing screen. Best I've seen yet. I also never watch HDR content because I don't like it especially in a dark environment.

My s21u [previous phone] was WASY WAY brighter than my current s23u.. Really weird and disappointing

Even samsung tv's does the same and most of Android phones. Its an eye protection protocole.

I noticed this also but thought I was tripping...it's bad when I watch UKposts on my phone 😒😒😒

I don't know if I agree on my s23 ultra HDR looks fantastic

It's because samsung is using anti glare coating for their display... it's a bit of a trade off.

It's bright enough for me

I dont see it, i compared it to my tv that is hdr2000 certified,

I wonder if he actually turned on video brightness under advanced and video settings which is were you can actually control the videos screen brightness.

Typical samsung quality control, now cant even get a few review sample to work, wow but not surprised as last 3 flagships ive had with faults/damage out of box n warranty tried charging me!!

I just watch videos on my phone with adaptive brightness, QHD, and 4K. I set moms iPhone to basically the same settings and we both agree my S24U looks better than her 14PM

No. Not HDR. Noooo!!! Whyyyyy??

Ia it just me or this video is not in HDR?

How is it broken when you didn't turn on bright video setting? It's a video power saving setting.

Mine blinds me, so...

I just found out that one of the only ways to disable HDR is to enable "Power Saving" mode which isn't practical, I wish they had an option or switch in the settings.

Need some views, cover The ultra line lol.

This is a very subjective review. How did you test it? Of course, Samsung will just respond with a generic answer, just like how you guys will answer this comment-a generic one.

UKposts needs to do an update on S24U because i get glitches when i use it on my Ultra but on my tablet.

I think the s23 ultra has the same issue, either that or I'm going blind.

looll u gotta redefine your meaning of hdr ... hdr wasn't never meant to brighten up scenes but to proper expose them rightfully to how it was originally filmed .. unbelievable

This S24 Ultra is pure junk, I'm sad I didn't return it when I could. Shitty camera, useless audio zoom feature, grainy display, problems in rendering HDR... And when I call Samsung they just tell me it's how it is supposed to be. This is the third Samsung item that gives me problems, my S6 watch classic 47mm stopped charging after 4 days (they sent me another one and it's ok), bought a 35l microwave and plate was not turning smoothly (they sent me a new piece with wheels), my first S24 Ulrra had deep scratches under the black screen protector from factory (they sent me another one). No more Samsung for me, their quality is down the drain.

I thought that was fixed with latest patch update

While it sucks that this isn't working as it should for those that use it. I personally think HDR video brightness is a gimmick and a lie. If you're indoors the regular brightness is just fine, HDR brightness just sears your damn retinas and throws the colors way off by adding white light to every lit pixel group. Totally not necessary, I turn it off wherever I can

I just tested my S22 Ultra next to my S24 Ultra and the HDR looked better on my s24 at least to my eye.

Nice video. Not a big deal for the avg. person.

HDR videos S24 ultra is dull as hell. Embarrassing

This is not a problem. Infact I'm happy that samsung has done this now. It adjusts the eotf tracking based on ambient light. It exists in iPhone ever since iPhone 12. Infact, samsung is only catching up to iPhone. But the key difference between samsung and iPhone and why samsung goes for dimmer presentation is because it adapts a dynamic eotf tracking based on the content Max CLL. This will preserve the highlight detail at the cost of overall APL. Modern televisions offer a way to enable/disable this feature of hdr10 content. Phones don't.
