I tried screenshots in Album; Video; & MX Player Pro using different codecs & 4K videos and all, but all came out in 1080p.
Not sure if it was supposed to be in 4K though.
So, how can we be sure that 4K content is being correctly?
Thanks.
The screen is 1080p by default, so if you take a screenshot, it will be a 1080p image displayed.
If there are sufficent pixels to push either in image or video format however, the device will push them up to 4K.
For example, if you find an image or video with at least 3840 × 2160 pixels, it will be shown in that resolution. View them via the Album, or Video apps (I'm not sure about third party apps).
If you do a Google image search for 4K wallpapers, you can try...
Thanks @nobnut,
But I have tried a lot of 4K content yet, even photos viewed in the album should be displayed in 4K if I'm not mistaken.
It's just I'm not sure whether the 4K kicked in or not, and would like to be sure somehow; can't rely on eyes alone.
I tested screenshots in Album, Video displaying 4K content, they all end up in 1080p.

Android 5.1 Lollipop DOES NOT support 4K natively. The system can't therefore produce 4K screenshots, and thus 1080p. The reason why it's not 2k res on the screenshots like Galaxy Note 5 is because Sony chose that the system should run on 1080p and not 2K.

Doh!
That's the problem. You are taking a screenshot in 4K mode... the screenshot is not taken in 4K resolution however, it is a 1080 screenshot, so it will obviously show as 1080.
You just have to take it on trust that 4K content is screened in 4K. You convert it back to 1080 when you take a screenshot of it though
@KbaB.BroS Thanks, I was reading about that limitation yesterday. Guess I'll need to wait for Android M! @nobnut I'm specially concerned about custom roms breaking the 4K functionality! Can't really trust 'em!
P.S.
I'm running RomAur btw, it's superb, except for some random reboots.
There's a kernel which restores DRM-tied functions as well, for unlocked bootloaders.
Your eyes may not be able to tell the difference. Basically, in album app, when you open an image, it'll be 1080p and after about 1-3 seconds, it'll crossfade into 4K. It's easier to spot with small text and on eyes.

@CLShortFuse There is no 'crossfade' with Image Enhancements off, at least on my end. Can't be sure if it's because of the switch.

Yeah, I don't know what to tell you. With or without X-Reality, you should see a change. Take a look at the sample photos by Yu Takae. The text on the bottom right should look clearer after a few seconds when 4K kicks in. When you swipe to change picture, it renders are 1080p. After a few seconds you should see things clearer.

I don't think the difference is FHD -> 4K transition, because you can clearly see the text even on a standard 1080p screen. I think the phone loads a light preview (the one used in the gallery?) and after that it loads the full image. It can be for being fast when you scroll pics. I made some tests with my old Z3 and default pictures of the Z5p.
And, btw, if you swipe between pictures it always reload like that. But if I'm in gallery it should be 4K always, no need to change the res.
Not as clear as when it switches to 4K. You don't need a second phone to test, just use another image app like Google Photos.
Take a look at this:

The way you know if 4k videos are working is to press play on the 4k video then 'pinch zoom' once and you'll see the quality (you can do this with any videos anyways)
Also the 4k logo in album in the bottom corner means the video is 4k. And the battery will drain more playing a 4k video then a normal 360p 540p 720p and 1080p video (because 4k bit rate is higher - hence more processing)

But even in Lollipop is possible to watch videos in 4K?

480p is nominally 640x480 (4:3), but if you look on Youtube, for example, you're not going to find many 480p videos that aren't 16:9, meaning 854x480 (Wikipedia lists that as a valid 480p resolution among several).
Is there a way to either change what 480p is in the camera menu or add a 480p (16:9) selection?
The other resolutions, 720p and 1080p, are 16:9, of course, but I don't always want to squander that much space when the quality isn't needed.
The answer to your question would be no. All of your video would be either sqaushed or stretched.
720 & 1080 are native 16:9 formats. They can be down converted to fit 4:3 and if it was filmed properly it will still look good because the camera man protected 4:3 boundaries while shooting 16:9.
If youve ever seen a 16:9 movie on an old 4:3 tv you will notice that its letter boxed and down converted to fit the screen.
Most consumer and prosumer cameras are 16:9 by default now because all of the displays on the market can show that content properly.
I don't follow your first sentence. I can understand the phone simply not being capable of doing it (I'm still hoping that's not the case, since 3rd-party ROMs often can do wonders), but if it could, then I don't see what the problem would be recording 16:9 480p (854x480). I would even think that it would be more popular than 4:3 480p.
Also, I have to think that 16:9 480p is quite common, since how else can so many 480p videos on Youtube be 16:9 (and these are often videos that top out at 480p, so they're not down-converted from something higher)? Phones are by far the most common video recorders, yet I can't recall the last time I saw vertical black bars on Youtube (what you get with 640x480).
A while back CM12 had a patch that enabled 4K video recording. I remember that it even worked SOME of the time, but mostly it showed to be recording without saving anything. Currently on CM12 and Blisspop the option is again removed - probably because it was buggy: review.cyanogenmod.org/#/c/103494
I've tried many different camera ZIPs from other manufacturers (Motorola cam, Lenovo cam) but they do not appear to enable 4K either.
I tried playing around with the media_profiles configuration file, uncommenting the 4K profile. This does enable 4K video recording - even saving, but the framerate is really bad (<10), both with stock and third party cameras.
So my question: Did anyone ever get smooth 4K video to work on AOSP? If so what was the combination of software used?
yes it did work for idiots who;
1) flased xXcameraXxfix_AROMA_VIPERPRO_v4_FAKXDA_LIKE_SUBSCRIBE_DONATE_YOUTELLMEBUGS.zip
2) set the resolution to 4K
3) shot a video
4) never realized it didn't even save, even if it did, it was lagging between 5 and 15 fps
TL;DR
no, it did not, i have flashed all the 3rd party crap from random monkeys claiming they fixed the camera on aosp promising stock quality
to those who come in here telling me it does, provide proof or gtfo

BUT, is there any non-stock ROM with STOCK camera quality? No 4K, I do not need that, only 1080p (60 fps or 30).
Nope Coki4, unfortunately Tehosiris is right: with the HTC cam and resolution "fix" I can record in 4K, but it is still way too low framerate (15 FPS or worse).
Voterx: To me 4K is most important, hence the thread. If i want proper pictures I take my DSLR anyway... 4K video is something that is really a beautiful thing if you have the screen to display it. There is a huge difference between 1080p and 4K.
To me it is starting to look like the camera driver in AOSP source is just not able to push the pixels?
Snap camera does it. I have also found that snap camera takes as good, or better in some cases, pictures as the stock camera.

What are you doing to get those file properties? Want to check what my jerky files say..
edit:
Properties here also shows 30 fps, but the video is jerky as fuuuuuu* - i guess it is saved "as" 30 FPS but it just drops a bunch. Yes it is 4K but def not 30 FPS, even if the file shows it to be (for me).
but.. if it is smooth for you I want to know your exact rom details so I can try to achieve my holy grail.
can one of the digital cowboys upload these fabled 4k videos shot on aosp?
i still yet to see a nonstock 4k video that doesn't lag like ****
@geekmystique the jerkyness doesn't show in properties, they are just the same as regular videos, you can check the properties in root explorer or any other file explorer.

Let's not make this into a flamewar of sorts.
This is a video I took of my hand waving in front of the camera, whatever the file info says, it is not 30 FPS - by far, it is dropping frames like crazy. The file properties say 30 FPS in MPCHC, but windows properties shows the truth: 18 FPS.

there is no such thing as stock quality on non-LG driver backed software
Anyways, i'm absolutely on geekmystique's side here, i've had multiple people giving me lectures how i need to flash xyz.zip set ABC settings to DEF, align my device towards Mars, count to 7 and stand on my left foot to have AMAZING STOCK QUALITY PHOTOS AND VIDEOS.
Guess what, i've done all those steps, flashed all the zips, pirated all the ****ty apks and gotten nothing but disappointment.
Thats why there is sarcasm towards these 'BUT MY AOSP CAMERA IZ BETTUR BRUH YOU SUK', when it's clearly not. Hell, half of the conversations ended at 'WHO NEEDS 4K' or 'I DONT NEED CAMERA ANYWAYS' which is ridiculus when it's these people giving lectures on how to flash stuff they don't even know what it contains.

I've noticed that any 60fps 1080p video or 4K video that I take on my Pixel XL and upload to Google Photos always shows up as plain old 1080p. Has anyone else noticed this?
I've noticed that if I download the same video in Google Drive to my machine, 60fps or 4K remains intact- but not when playing back in the browser (either in Drive or Photos).

When playing back in photos, do you adjust the quality in the bottom right? (Similar to YouTube)
Update: I see now. Even though it's got the quality options in the lower right, the options are limited to Auto are various resolutions from 1080P on down. No 4k or 60fps. Weird.

Yep very weird. I haven't seen anyone else talk about this issue either.
I am guessing that like YouTube that because the screen of the Pixel XL is 2k it doesn't give the option for 4k play back on the phone itself
That's a shame.... It should at least do the 60fps
I cant get Netflix app to play videos with higher resolution than 720p and 30 FPS. The S9 has hardware capability to show 1440p and 60FPS, but Netflix seems to limit this to low resolution.
Any fix for this?
I have tried it on out superfast Wi-Fi and superfast LTE, no difference.
You can check this with Netflix own "Test Pattern" videos. Actual FPS and Resolution is shown in upper right corner when you zoom out to original video size.

I tested this method today, it works! So it is indeed app limitation NOT subscription. Tested it on my s9 and girfriends s9+, both worked. However, getting to 720p resolution on the newer versions is much faster than getting to 720p or 1080p on this older version. So maybe locking to 720p is the effect of some network and streaming optimizations.
Had to go older to get mine working

I am unsure if this thread belongs here. Kindly let me know if it doesn't or please move it.
I was wondering if the TAB S7/S7+ would let me play YouTube videos on 4K using the native app but unfortunately it doesn't for obvious reasons using stock settings.
So I figured a way to enable this using ADB. I am unsure how much this affects the battery life since I am still testing app compatibility and power usage.
ADB Commands
1. To set 4K resolution -
adb shell wm size 2400x3840
adb shell wm density 1024 (or whatever suits your eyes, mine is 1200)
2. To reset to default -
adb shell wm size reset
adb shell wm density reset
So if anyone's interested all you have to do is -
1. Download minimal ADB and install it if you do not have ADB installed.
2. Open Command Prompt in the ADB folder by pressing Shift Key and selecting the Right Click option "Open command prompt here".
3. Run "ADB devices" without quotes and accept the prompt on your device (Your device must have USB debugging enabled, if you don't know how or have it enabled you probably shouldn't be doing this).
4. Run the above "To set 4K" commands to set the display resolution to 4k.
5. Clear the app data of Youtube and restart the device.
6. (Optional/Reset) To reset the display resolution to default, just run the 2nd set of commands.
Not sure this is actually making the screen dislay 4k.
It doesn't actually MAKE your screen 4k as the display only supports 2k. The device renders everything in 4k and then outputs it on the display just like what Retina Displays or Nvidia DSR (Dynamic Super Resolution) does.
Just in case you want to actually make sure everything is running in 4k, you can simply try running a 4k video on Youtube which otherwise you cant!

Right, so what's the point? The 4k video doesn't look better on a 2k screen.
Since DSR and Retina Displays already exist, I believe there are some advantages. You have to try it to believe it. The displays feel a lot sharper, edges feel smoother, fonts look amazing, overall it just looks good on the huge display of my Tab s7+.
Coming back to that I need to ask you, did you try this before asking me the POINT. Coz I feel if you would have, you wouldn't be asking me this!

Yes, I did, and it looks no different. It's a 2k screen, enabling something to load a 2k screen with 4k will make no difference. Not trying to argue, just saying, it's pointless.
I accept it doesn't make any greatly significant difference but then its subjective. It was just an experiment and I wanted to try it. There are many people out there who always want to run youtube at 4k, this was simply my answer to that problem, although it has its own downside and implications.
Thanks for figuring this out! Often 4k will look better on a 2k screen than 2k on a 2k screen.
This is because pixels from youtube don't always line up perfectly to the tablet pixels and you end up with a resolution less than 2k when you have it set to 2k. When you stream at 4k from youtube, the content is delivered with smaller pixels and ends up looking better on a 2k display.
Thanks for this going to give it a try on my 7 plus.
it worked now i get the option to 2160 resolution, it does look sharper.
good work thanks very simple
Hey
When i use the command "densiti" my screen become wery BIG otherwise the "size" resolution is great
is that normal ??
There's also Newpipe to get 4K Youtube without hacking. As a bonus, it also gets rid of the ads.
Does this work on Netflix? Will the maximum resolution on netflix and prime video change to uhd?

The point is higher bitrate. Youtube compresses videos so much so 4k will have a much higher bitrate than 1440p and look better.
Btw, use youtube vanced for 4k but use sparingly as it blocks ads. I wouldn't suggest using it very often because it doesn't support creators
What about on Samsung Dex or any kindof screen mirroring on external monitors? Any way to get the S7+ to send more than 1440p to an external monitor through any means?
For instance if you set the resolution to 4k with ADB, and then you mirror your display via a [email protected] usb-c / hdmi cable to your 4k screen, will the screen receive a 4k signal?
Can anyone (Stryker_Echo9er) try that?

If you have unlimited data and an old device lying around (all it has to be able to do is run the official Youtube app), you can leave the video playing on that device with ads while you watch on your S7 or whatever without ads. Best of both worlds, the only extra you pay is that little bit of electricity to run the other device.
YouTube now natively supports 4K HDR.
Now you can watch high quality 4K YouTube videos on Android phones
Support for 4K HDR playback was only there for iPhone users while Android smartphone users were only able to play YouTube videos at a maximum resolution of 1440 pixels.
