Not sure if this is an issue with the phone or Youtube, but I've uploaded two videos now testing the 4k footage but when I select the 4k option, it loads for a little while then switches to 480p
Anyone else had this problem?
it's just you I guess, cause the youtube video plays in 4k for me

Hmm. My computer at home wont play it, neither will my one at work, both of which are dual quad xeons with titans.
This video works fine for me
But this one doesn't
Can you see this one? It was taken with my G3 and uploaded with my G3 and it showed as 4k when I watched it with my PC

I set my settings on video size to UHD 3840x2160 before taking a video. And when i tried to share it on youtube, it doesnt seem to be 4k. Is there another way to do it?
What resolution does it come up on YouTube? Also are you using the youtube app on the Note 4 to view the video?
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?
On iPhone 5s, even it doesn't support 4k recording officially, we can record 4k video by installing an app called "Vizzywig 4K". It captures full 4K resolution photos (3840 x 2160 pixels) at 24 photos per second while capturing an audio soundtrack separately. Is there any app similar on android?
You need a camera that officially supports 4k before you can record in 4k. I highly doubt this app can 'magically' allow a camera to record in 4k, it is mostly placebo. The zenfone 2 can't record in 4k as it's camera only supports 1080p Max.
You can try open camera.

This app is proven to be work, just did a Google search. http://www.engadget.com/2014/09/17/hands-on-with-the-1000-vizzywig-4k-app/
Also this app work by taking 24 photos in one second, so is it possible for our ZF2 to do so?

I have tried it, it can only record 1080p even the option for recording 4k is enabled
Perhaps what I am looking for is an camera app that can take 24 "3840 x 2160" photo in one second and than combine these photos with a sound recording to form a video.
No. You can't do it. Even if it did work, it would be very shaky because you are not considering the lack of image stabilization. The ZenFone 2's shutter speed is just too slow to capture 24, much less 15, photos per second.
I noticed the video camera is a bit "bouncy" and does not stitch very well. What cameras apps on the play store will be better than the one plus 3 stock camera app?
Optical image stabilization is currently not working when shooting in 1080p. You'll get it if you record in 4k at the moment.
Other than that, Cinema Fv5 is a great app for recording, although stock is far easier to just pick up and use.

Excessive hand movement leads to ripples forming in the video recorded in 4K.
I wished it was fixed....
any idea how to get it to work? or we have to wait for an update from OP?
Having this issue in 720p and 1080p, in 4K seems to be better.
