Hello all ,
I've got a Note for a week now and altough it's an amoled screen , i've tried every kind of video from avi to mkv ( 720 p quality ) and even reencoded files to mp4 or h264. But black aren't deep black and more dark grey , sometimes even pixelated ( blocks ). I even got the impression that this was also sometimes the case with some games ( for instance the opening sequence in Asphalt 6 HD ).
Is this normal with Samsung devices and is there a way to improve this.
Thanks
SEE?
Gnote has same specs as the galaxy s2!
just 200 more hz on CPU.
Should play all those files man!
if no worky on note byt works on SGS2 then u have somekinda fail version manufacture thing!
try getting it replaced if it does not play avi or any files!!
it really should work! try some file on sgs2 if its ok there then u phone deff a bad batch!
get it replaced! u have good Reasons to get it fixed?
helped?
He didn't say anything about the files not running, he mentioned a complaint about graphics performance due to non-AMOLED-style deep blacks.
Ffs...
Thanks
Hello ,
I probably didn't express myself completly correctly.
The Note can play al those video file and even mkv without any lag , the problem consist in the fact that the blacks in the video are not realy black but more greish , like if the contrast was not calibrated right.I even got blocks in the black part of the video.I don't have that problem with photos.
It's also like there is oversaturation , i have tried the stock video player , act video and mx player , all give me the same result.

It looks to me like its video quality issue. If you run video provided by samsung "lightness & slimmess", you can check whether black colour is properly displayed (skip to 0:55 for the best result).
Thanks
I have done what you said and the black of this video are completely black.
This is a 1080p hd video.Does that mean that only hd videos work propely, I hope not.
The video with the problems could be played flawless on my Htc Sensation or on my Asus Eee pad transformer both with a slower processor.
Sounds like the OP's video bitrates are too low, since he is describing black crush. Higher bitrate videos do not exhibit those problems.
Thanks
This is propably the reason , but what do you mean by "OP's" .
Thanks

Here endeth the lesson!
Mine does this too. the samsung video plays fine but most other blacks are purplish and blocky. This happened in the green lantern film downloaded from the market, the first part of it is very dark and was unwatchable. It happens to a lesser extent in 1080p trailers downloaded from the net. When I use a black screen for my lockscreen it is the same. Even the starry background during the orbiting planet part in quadrant benchmark is a blocky purple mess. It is not even constant. Occasionally it seems OK. I am going to send mine back.

If the Samsung video plays fine, and other videos play fine, like MKV's in Diceplayer then it must be the videos you are looking at.
Good luck finding a device that plays back crap videos in perfect quality.
If you do find a device that makes these videos look good, I would question the bit depth of that device.
What is the point in getting a device with a HD screen and watching videos in sd or HD with low bitrate? It's like trying to watch VHS videos on a LED.. yes it will be pixelated. I suggest watching higher quality videos. Either MKV or xH264 mp4 with larger file size and bitrates of at least over 3mbps.
I think this whole issue can be explained by the technology in place here.
Super AMOLED does not light up black pixels at all, so when slightly gray/dark gray colors appear in the black, they tend to stand out much more than they do on different screen technologies.
Solution: higher bitrate videos, and/or deal with it
i have been doing some testing and i know exactly what the op is talking about as I'm suffering the same issue. i have a galaxy s2 and the note side by side, with the same video and the s2 renders correctly but the note is blocky and not rendered right.
I'll post a side by side photo when i get home tonight, but there is definitely a problem.even using high bitrate videos. i tried to even the playing field eg set brightness to max, adjusting the colour to normal, warm or even cool but it does NOT render correctly. it almost looks like the old days of 16 bit vs 32 bit colour on a pc. side by side with my s2 and s1 it is very obvious.
YUP. Am observing this too.
The initial Galaxy S (first) had a pentile matrix screen too so it would be useful to compare a video exhibiting the blockiness on a Galaxy S side by side with the Note.
It definitely does seem like it is rendering at 16bit, sometimes even 8bit.
Also I have observed this in the general OS too i.e Icons, pictures etc...
Am note sure what to think...
I am wondering whether Sammy reduced the bit depth throughout the OS to keep the frame rate as high as possible due to the higher resolution of the screen...?

Oh wait - you tested the Galaxy s1 as well which has a pentile matrix AMOLED and your test video rendered correctly???
yeah the s1 renders correctly. i tried do a screen capture of the video on my phone but it didn't seem that you can't do a screen capture of video running i tried the default video player, mobo player and mx player. none render correctly nor can do screen capture of the video still
I'm curious to know what he means by 'rendered correctly' on the S1. I think its more likely that the S1 resolution just isn't good enough to expose the weaknesses in the video encoding - the Note has nearly three times as many pixels as the S1 and the screen size is considerably larger so the 'faults' being described here are IMO the screen being good enough to expose weak video. Like someone mentioned earlier, it like watching an SD video in a lossy format on an SDTV and then an HDTV...

You are describing video with "bad" gamma. It is not the screen or the device it is your source material.
The "blocks" you see are compression artifacts. Most video you will get that is compressed will have this effect. If the demo video doesn't show these artifacts then it can't be the device. That of course doesn't rule out a dodgy video player app included with the device. Maybe that is sub par and has crappy coding of the codecs and makes bad video worse?
The reason you see them better on the note is because OLED screens will show shadow detail very well. A few stages above pure black will show up. Videos these days are calibrated, made and tweaked to look good on an LCD as it is the dominant tech and that is what the video makers are looking at while they adjust their settings. This means that colors and black levels adjusted to look good on an LCD may look like crap on an OLED.
On LCDs the backlight haze will often wash out these shadow details and crush the blacks so you won't see these artifacts as much.
You problem is that your screen is TOO good!
There lies a fault with the video player. There should be a gamma adjustment to be able to pull these "grays" closer to black.

what i mean is, i have the note, s2 and a s1.
lined up side by side playing the same video, the note's video in some parts is grainy, blocky, pixelated, the colors not correct compared to the s1, s2.
and this is with screen brightness set on max on all phones, display all set to standard, using the default samsung video player. but it makes not difference if you use moboplayer, mx player it is still bad.
like i said i'll post a picture when i get home later. i'm hoping it is a fixable with a software upgrade as i watch a lot of shows on my phone and so far i'm not impressed with what i'm seeing. even using 4gig 720p videos.
i've checked the video on my monitor and the video is perfect so it is just not getting rendered correctly on screen.
i hooked up the note using my s2 samsung mhl cable and in the lounge the video on the 55in 1080p tv is obviously inferior to the s2

Hi guys, I'm thinking about buying the Samsung Vibrant (That's the US Tmobile version of the Galaxy S for clarification) and I noticed that it can play 720P and it has a WVGA screen. These days, a lot of phones are capable of technically "playing" 720P video but none, even including the almighty retina display, have hd capable screens. But I was just wondering, besides being able to play its own recordings, what is the point of watching HD videos on a screen that really can only play 450P (keeping to true wide screen aspect ratio of course)? It just uses more battery and system resources to decode the higher res video when the end result is identical. Watching 720P on a WVGA screen is tantamount to hooking up a Bluray player to a non-HD screen. What's the point?
And yes, I'm well aware of the phone's DLNA capabilities.
Beats re-encoding right?
I think because the screen is so small and the resolution is high, it gives you the illusion of watching something in HD. If you compare a DVD rip to a 720p video on Galaxy, you'll definitely notice a difference. And the Super AMOLED screen helps too
Yeah, I can see how it's more convenient to just throw it on there raw but it seems like I'd rather take the effort to make it a lower resolution to save space on the phone if it looks the same either way?
And is there really that noticeable of a difference? I'd love it if someone could show a comparison picture between the same scene of a video in 720p and 480p on the galaxy screen to see if it's significant. Also, it might be possible that android is using sub-pixel interpolation to emulate the higher resolution.
Well the screen is a tiny bit wider than the 720 pixels you get from a DVD. Better to downsize than upsize, especially on such a sharp screen! I find that when watching DVD quality videos on a laptop, you notice the artefacts and low quality less than on the phone.

720p is actually 1280x720 pixels, the phone has 800x480, there should be no difference to your eyes from viewing a high quality 480p video or a 720p.... People are probably comparing a low quality 480p DVDrip with a high quality 720p video, and that's why they are seeing a difference (color quality and sharpness play a big roll here). It makes no sense to watch HD content on the phone, a good 480p will look just as good and will take less processing power...
Thank you!

That is exactly what I've been saying this entire time! And since true 480p is actually 848 x 480, I've been encoding all my videos to 800 x 450 because my hd2's screen just can't take proper advantage of hd. Somewhat ironic considering its name. It requires less processing power and with good encoding, you lose very little quality compared to the original video. This whole 720P playback seems to be just another marketing ploy like the megapixel battle was. Just another bullet to throw on the spec sheet.
Update: If anyone reading this would like to test the quality difference between video resolutions on their respective HD capable device, here's a great test clip in several resolutions: http://www.bigbuckbunny.org/index.php/download/
Yes, it's ideal to reencode to maximize size usage if you're gonna keep the video on the memory for a period of time.
However, for those HD videos that you've downloaded, and you have no wish to dl a SD version of it just for portable viewing, and it's something that you're gonna watch once and delete, that's where the functionality to view HD media comes in handy.
In short, it's more convenient to have the ability than to do without it.

Very true and i believe the 720p which actually is for the video output..i just got the Nokia CA75-U cable and the 720p video playback is amazing on big screen TV.

Yes, but I meant DVD resolution which has 720 pixels in width.
Besides, my entire collection is in 720p HD.. So when I'm going out and want a movie/series with me for boring times when travelling, it's nice to not have to convert them/re-download a lesser quality rip.
I also think I see a difference, tested with a SD-rip of Top Gear vs HD-rip of it. But might just be in my mind Seems sharper though.
You kow, videos encodings are at different resolutions for luminance and chrominance data.
Color data is often half or quarter the resolution of the actual video resolution.
A properly encoded 1280x720 video will look better than the same encoded at 840x480.
Considering the processing power, when video decoding and scaling are done by hardware, power consumption will be almost identical.

Not practical only for you maybe, but different people have different needs. Don't assume that you can decide for the whole world.
Seriously can't work this one out, do I get my screen changed or not?
Should I wait to see if ICS makes it any better?
This phone is perfect for me except this issue with the blacks / greys. Even when i zoom in on dark parts of pictures taken with the phones camera it turns into a pixelated mess, so this is defiantly not a low quality source issue, its hardware or software related, but which?
Advice please guys. Many thanks!
I know! Right?
The screen Is freaking awesome, simply the best on any smartphone, but why those blacks haven't been fixed yet???

I really am at a loss to what you guys are complaining about. I'm either not that fussy, or deluded to the fact that what I think I am seeing as 'bad' I pass off as something else.
From what I've read around the forums, what should be a shaded series of greys/blacks in an area are appearing as blocks of black/darkgrey instead of a gradual change.
I've always thought this was down to how videos/images where compressed or decompressed and displayed - which would almost certainly be software and not hardware?

Same here. My blacks look fine most of the time. When I do get grey blockiness I'm pretty sure it's due to poor compression in the video file, because other videos, large black areas look fine.
Can anyone give a link to a video available online in which this problem occurs (and the point in the video we should be looking at).
Maybe then we can get some objective testing with everyone using the same source file.
Maybe even have people doing screenshots to compare screens.

I'm rarely using my phone in dark enough conditions to notice.
ICS should improve gradients, but won't fix the black crush if it is indeed a problem with the screen hardware.
I am probably going to regret this, as my Note was perfect except for this black crush issue, but I sent mine back to be replaced. And the issue was not just on videos for me so poor quality encodes are not the problem, I was getting it even with pictures taken with the phones camera. Said pictures taken with the Note displayed fine on my pc and my wifes Galaxy s 2, so it is deffo a problem with the device.
Please lets not turn this into another "who cares" or "its not that noticeable" debate like the other threads, all I am aiming at with this thread from now is to find out if there are any Notes in existence that do not have this issue!
Thanks.
I refuse to look for a problem that is not there.....
There is no phone or portable device in existence that is color accurate, either tonally or temperature or gamma correct out of the box, and to expect such is to be, well, expecting quite a bit too much.
Why do i make that statement?.. Well, given that a monitor or TV at ANY price are not accurately calibrated.
To get an accurately calibrated monitor requires a display worth using, then a color tone/temperature/gamma calibration system (which is ~$200 & up) and software that can use the resulting calibration profiles...
The SGN is a phone... tbh there is no "fault" or "problem" here, other than unrealistic customer expectations...
Would a settings app that could set globally set color temp & gamma be helpful? sure.. there is enough color temp variation in the spread of production tolerances in phone to make this useful... stop a ll the pink white /blue white issues
But will it make the SGN a color accurate display?.. no.
So... lets wave a magic wand and make it so... whats the point? the camera does not justify it, the movies you watch are overly compressed and not color accurate (never mind compression artifacts of banding, blocking and shading), youtube videos have no quality controls.. online TV, website videos and stills have major color saturation issues.. so what content will you access that is going to be useable on a color accurate display?..
well, 4 beers down and 2c more spent..

Dude, my pc plays / displays these movies and images fine with no artifacts, as does my tv, as does my partners Galaxy s 2, as does my Nexus s, so how can you say that there is no problem?
Anyway, I just had a look at my cousins Galaxy Note and that one is playing these movies fine, and is displaying the pictures taken with my Note without the chess board effect, so if you are happy to pay over £400 for a defective device thats up to you, but many of us expect to get what we paid for.

The problem is clear enough to see there, but it's not one I've ever noticed on my Note. I just tried playing this YouTube clip on my Note....
http://www.youtube.com/watch?v=syxd2n8S4AE
and could see nothing wrong with the video performance in a darkened (curtains drawn during daytime) room. I wonder how well this clip plays for other people on the Note.
I made a video of the Note playing this clip and I'm uploading it at the moment. It will take a while (81 minutes remaining at the moment) as I shot in 1080p. I'll post a link when it's ready.
FWIW I'm on the latest official ROM and my phone was sourced from Germany in early November. From my perspective there is no problem, which might make it quite hard for Samsung to fix.
My Note is running on ICS (CM9) and the color rendering is substantially improved over stock GB. Gradients are smoother and blacks are rendered cleaner.
My video is up.

I've played the same clip on my Note and it looks exactly like yours, no banding/crushing/clipping whatsoever.
I've tried a lot of Youtube clips and movie trailers but in only one of them I could see obvious artefacts during a fade out. I played the same clip on my pc and saw the same thing happen there so that's probably just lousy encoding.
Thanks for putting that video up, I hope my replacement looks like yours, its due tomorrow.
I got me new note, this one is set to uk language instead of german like the one I returned. It has the exact same issue, drops from 4 grey to 3 complete black and i am still getting the clipping, bloody Samsung, this was meant to be an upgrade from my nexus s, but most stuff looks better on that! Not gonna excahnge again, I will wait for ICS and see if Samsung actually acknowledge the issue.
@Mystic38. Whilst I agree with you that most consumer devices don't come calibrated to industry standards and that most consumer devices lack the essential settings found on the most basic of professional displays, I fail to see how any colour, contrast, hue, gamma or brightness calibration would affect the overall appearance, unless of course you are cranking the settings beyond anything useful and crushing the dynamics intentionally.
It's difficult to introduce visual banding or blocking in high BIT rate video or lightly compressed images by tweaking settings and calibration by a couple of percent alone, as there are near on 17 million colours. This leaves thousands of grey levels to play with and the human eye shouldn't notice banding or blocking with that many greys.
This presumably points to an issue with the way that video is presented to the screen driver or how the screen driver drives the screen. There's probably an issue with crushing where the hardware converts the digital signal to electronic levels of each AMOLED element. I have seen this problem on other devices, not just phones and most of the time it was rectified after a software upgrade.
Another thing to remember is that companies like Samsung are fully aware and accommodating of the fact that a lot of people now use these types of phones as monitors for photography and video production as I do. I use DSLR Controller and have no problem with crushing. Using the phone as a monitor has been extremely helpful and negated the expense of something which would have cost over 10 times the price.

I just got round to trying the ,png gamma test file on my Note. It fails the test. Everything below 4 is black and as you go through the numbers from 4 and above there are bands grouping four levels into one tone. Worse still, the tones alternate from greenish to purple instead of being shades of grey. Interestingly if I perform a screen capture the capture is a true reflection of what I see, which implies to me that the Note is actually sending bad values to the screen rather than a hardware problem, because surely the screen capture only cares about the data, not the physical appearance produced.
Looking at the same file on my laptop everything is presented correctly, so obviously the file is not the problem.
Yet despite failing this test I have never noticed a problem with the Note to cause me concern in normal every day use.

Have you viewed it in the gallery or in a browser? With my Note everything below 4 is crushed in the stock ICS browser but I can see everything in the gallery.

I think the gallery uses a different color gradient and temperature than the stock ICS browser, much as if you view a rich encoded black contrast video on the stock video player and on a custom app video player like MX player... you get varying results...
I think this issue is a mix of both a hardware and software one, and though the Official ICS upgrade "might" alleviate this problem, I surely believe also that since this is a combination of a hardware problem, the clippings are still there but perhaps not quite noticeable anymore....
hello community
I bought my tab s T805 a few days ago and yesterday watched "The Strain" on it.
Everytime when a black part (hair, clothes etc.) moves, there was a caudate behind.
Very annoying if there are more black objects and the camera moves...the whole picture looks unsharp.
Seems like it´s a comon problem of AMOLED Displays, because my Note 3 shows the same behaviour.
Anyone else noticed this problem?
Maybe it´s only the display of my tablet...
what app do you use for media playback and whats the source? own blu ray rip or purchased online etc?
I use Plex, Video is H264 rip of the blueray.
The Plex server streams the video to the tablet.

Yea, I've noticed this a lot. Doesn't matter if it's a game, movie, or static image. Any deep black spots will "smear" across the screen a bit.
Damn...beside this problem, the screen is really great!
Maybe I send it back and get an alternative...
As far as i know, only TabPro and Note 10.1 (2014) also have the same resolution.

Good article. I disagree with one thing, though I've never heard of OLED described as holy grail of motion blur. It's the holy grail of black as the pixels can shut off completely. But as for motion it is pretty much in same boat as modern LCD. LCD now has very fast pixel response too (not as fast as OLED), but because of sample and hold it has motion blur. Ditto OLED.
Even the $25,000 LG OLED uses sample and hold and has some motion blur. So yeah don't expect great motion in your $400 tablet.
I though Samsung had fixed the motion blur or at least improved it by not fully turning off the pixels so it take less time for them to respond, so it`s not jet black more like dark, dark, dark grey
John.
Interesting side note. There will likely be a specific need for low persistence OLED displays for virtual reality applications in the future. This is an excerpt from the Oculus Rift website:
Low Persistence OLED Display
DK2 uses a low persistence OLED display to eliminate motion blur and judder, two of the biggest contributors to simulator sickness. Low persistence makes the scene appear visually stable, increasing the potential for presence.
Some facts about the OLED's used in the Oculus Rift:

Oculus' DK2 uses the Galaxy Note 3 AMOLED panel, overclocked for lower persistence:

I have been unable to see any motion blur on my T800, though i mostly watch animi, i do watch movies as well.

It's easily testable with a black image with some dark details on it like this one. If you even gently move it around in an image viewer many of the details will simply disappear.
Are any of you with this issue using power saving mode? I found that the slower refresh rate in powersaving mode does cause some screen issues.
Ok maybe a little dramatic but still - a little disappointing.
I have done a few tests. Played the exact same HDR YouTube videos at the exact same time with my Mate 9 and Mate 10 one above the other in landscape mode. The Mate 9 is MUCH brighter than the Mate 10 on maximum brightness. I have factored turning off auto brightness and turned off Smart resolution etc etc. They also have different colour temperatures even if you set them both to warm, default or cold - they still look different.
I have tried HDR videos on both phones and I see absolutely no difference. I studied the colours so hard. I see absolutely no difference between a 1440p video and a 1080p video playing at the same time. In fact, most times the Mate 9 looks sharper and more vibrant. Also shockingly the Mate 9 offered for example 1080p 60fps option on a video whereas the Mate 10 offered maximum 720p 60fps on the same video. 1080p was nowhere in the list. What the hec! Battery at 100% so no resolution switching to save power.
Basically, it is true 1440p is wasted on a phone. There is no difference on a small screen such as a phone. All these people saying "yeah but X phone only has a 1080p screen" don't realise that it doesn't really matter. It all looks the same.
So I hear the Mate 10 is HDR 10 compatible and yet I don't see it with my eyes. If I am doing something wrong and someone wants to correct me, please DO. I want to be wrong.
What are your tests and opinions?
Despite all this, I still love the phone. ?
I take it all back.
I have discovered YouTube does not show HDR10 output even if the video says so.
ONLY the built in video player supports true HDR10 content.
I downloaded these HDR sample videos from an XDA post:
https://mega.nz/#F!jYwlgbBA!piXwD8sYa7zjsRtjStuAyw
Play them in the default video player and they look stunning. I took a screenshot of a paused video and when opened up in gallery, the colours were bland compared to the actual playing footage. Proof enough.
Phew! This phone is amazing!
Do you get higher peak brightness when in vivid mode ?
AFAIK - Currently Netflix is the only third party app supporting HDR 10 for this phone
Youtube coming soon though,
So, you might want to change your thread title, LoL

Of course it's the same because mate 10 comes preset to 1080p lol. And stop listening to tech reviewers the are dumb, only way to see it 1080p and 2k is to use magnifying object like camera or glass etc. I have iPhone 7 plus, LG G6, Moto Z play, Essential phone and the s8 which I sold because of burn in, I don't see the dots pixel on any off them because I don't look for it, they all looks the same some are brighter and vibrant than others. That's it.
Another thing, the max brightness on auto is superior than the manual max brightness. That happen on a bunch of smartphones.
So, it's dumb to compare max brightness with the auto setting turned off.
The best way to compare it, is going outdoor with the auto checked on both and look which one seems brighter.

Hi Guys! Im looking for a phone that is the best in low light video (not photo!!!)
had an s9 on me a few days ago but the videos were way too dark in the situation i need it for.
now i found this video on youtube, can this be legit, or some gimmick used here?
Huawei P20 Pro - moving in low light : Bucharest at night 4K
the dark places (park, under trees etc) look way better than the s9.
but its hard to believe, i read in lot of reviews that the videos on the p20 pro are mediocre, not as great as the photo quality.
i suspect this was made with DSLR, not this phone....
any opinions? thx?

It might be real...I own one and the video quality is way better since android 9...I will make a video tonight and upload it on youtube and post it here...and let you decide. The light in that video is not bad,because of the street lights,so not so hard to be at that quality. But I always make videos ad 1080 60 fps,it's better in my opinion and stabilization is active.
But I will do it at 4k in a few hours(they obviously put the phone on a stand or something,the video had no shake at all,I will do it by hand,so a little shake will be in my video,the stabilization is only active at most 1080 60 fps)
Please note that the p20 pro does not have image stabilization in 4k. They used a gimball. That is indeed p20 pro, I recognise the wavyness of the video when panning around. However... The video quality is not good. Samsung is better at that.

hey thanks but if not a problem for you, plz make a video in the lowest possible framerate/resolution.
allow me to be more precise. im looking for the phone i can make a usable video in the lowest possible light.
i live in a problematic neighborhood, and if there is some argument that i record for evidence, i need video that is not just a black screen...
i dont need 4k for that, in fact even 480p would be enough if it has best low light sensitivity.
i try to attach 2 examples . THESE WERE MADE WITH S9!!! not p20 pro
1. part of my room with a 15W lava lamp. as you can see, apart from the lamp, everything else in unrecognizable (guitar on the wall, computer desk) you can barely see something is there.
2. garden+street with average suburban lighting. at the end of the video, there is good lighting, but if something is shadowed from the streetlight (tree, bushes) you basically see nothing, just pitch black. you woulnd even see if a person is there or not.
i converted to gif for better uploading but on the original videos the light level was the same, you cannot see nothing in the dark parts.
thats why it was hard to believe in the first post video, you can basically see everything, even in the shadows.
guys it wont properly play the above gifs, and many times just hangs. XDA site problem or its on my side...? thx
I do a ton of recording at EDM shows, rapidly changing lights, lazers, etc, and I've been beyond impressed by the video quality. The details this camera catches is nothing shy of amazing. I also don't bother with 4k, because in all honesty, I won't be viewing the videos on a TV large enough to take advantage of the resolution. So for me 1080P is more than adequate. Plus the steady shot/stabilization is definitely needed at my shows. My only complaint about videos on the P20 is the volume in loud environments. Ideally I should be using a usb-C microphone, but it's just easier without.

Ok,I will. I did not have time yesterday. I will make a video in my room,with light only from pc,and another with the monitor turned off,I have lots of leds so there is some light,but very low.
Here you go,I made a video in my room,the only light source being my pc: https://youtu.be/Hb5nxI_APNA

just 1 more thing. if you turn off the monitor, but put the video in 720p/30 fps, does the camera "see" anything?

There is no stabilization at 1080p 60 fps. You will only have it up to 30 fps.

Of course not,only the leds from pc,but in picture,night mode it can capture a lot more detail than I can see with my eyes.
And the video you saw captured very well,I did not see much more than the camera,it was very dark in the room.

thx, sorry, i was looking into other phones thats why it took long to get back...
i understand your reply, thats exactly my problem. im pretty much convinced that the original video is fake or cannot be made with a stock p20p camera app...
i live in a similar city like Bucharest where the video is made, eastern europe also.
in a business disctrict maybe, but in parks, normal streets etc we just dont have enough light for that
if you check the video you see that everything is visible even in the shadows, for example someone couldnt hide there cos the camera would see him.
thats just not realistic. i watched your footage, and is very similar to s9, although i had less light, but not complete darkness, sort of in between.
yes i know the night photo is great but i couldt find any evidence that it has better low light video then other phones... (apart from that one in the post)
i mean if its that good, how come we dont have a lot of amateur videos, or vlogger videos made at night with the p20p..?
just doesnt add up for me.
ps: i checked, my light was about 1/3 of your white PC screen.

I did not compare it with other premium NEW phones,but it's good enough for me,if I ever want to make a video at night,most probably it will be inside a house,a pub,or even outside is good enough with street lights...if you need more,I don't know what to recommend to you,I did not research enough. But I do know it's better than cheaper phones for sure...and better than my old P9 and my Asus Zenfone 3(which were both premium when they were released).
