Which video apps have 4k playback enabled?

Don't spread misinformation. Netflix released HDR support some days ago for our phone.
Sorry my bad. I got the app a few weeks ago and didn't see the update. I also left them bad feedback lol. I'm going to check out Netflix now
thanksHe wasn't spreading mis information. HDR and 4k are not the same thing. Can't find it said anywhere that they support 4k yet.
My bad. I understood wrong , so sorry for the unfair accusation
. Yeah we still don't know if Netflix streams their content on 4K along with the HDR.EDIT: Does anyone happen to have a premium Netflix subscription so we can know if our phone supports 4K along with the HDR (if it's possible to see the resolution somehow).

they have [Ultra HD] in the title, from what I see. it will also say "Ultra HD" at the bottom after a bit of streaming.
doesn't seem to specify HDR or not when playing, but the Ultra HD shows are in the HDR channel.
other apps seems to show "HDR" in front of the current resolution, though.

of course that does pose an interesting question, if you cant tell if your watching 4k HDR then whats the point other than decimating your battery .
Personally I can tell HDR a mile off, on the other hand 4k MOVING content on such a small screen is a lot harder to see than you might think. on such a small screen I suspect the vast majority of people will never notice if its a 1080 or 2160 image they are watching but the HDR will be clear as day.
HDR on a 50in 4k TV looks absolutely stunning, but generally speaking, on a small screen the biggest benefit most people will be able to notice unless they are sitting an inch from the screen is the HDR, that is the most noticeable element to the 4K package and you can get that with a 1080p video so....
(Cue die hard fans declaring otherwise)
just saying, don't be expecting a monumental improvement on Netflix or Amazon when they go 4K, if you are already getting HDR then you are 95% of the way to a great picture.
4K HDR on a massive TV on the other hand is unbelievably beautiful the best way to describe it is that its like looking out of a window, the biggest part of that is HDR but on such a large display the detail is incredible, without pressing your nose up against the screen

I disagree. The difference in sharpening and details is noticeable in 4K, especially in high contrast and action scenes, even if you are watching the video 30 cm away from the screen. But 1080p is still good if you watch certain videos or when want to save the battery.
except to say that's all in your head. you want it to be true so it is. That's not a dig at you or anything, that's just the way our minds are wired.
on static images you can just about tell on such a small display sitting at a normal distance away of around 20-30 cm, but on a moving image on a screen that small, you physically cant see a difference, its biologically impossible unless you have what would normally be bad eye sight
Its been shown time after time in double blind tests that when two high bit rate images are displayed on the same small size screen and at the same distance but one being 4k and the other being 1080p, there are as many people who think the 1080p looks "better" as there are the 4k.
its subjective. throw in a moving picture which may deliberately contain noise and its virtually impossible to tell UNLESS, you get close enough.
I'm sitting in front of two screen just now, one is a 4k monitor, the other is the 1080p panel in this laptop. I have the same image on both (a 4K image) and they look identical unless you get close enough to see it.
Our eyes are pretty cleaver things in fact they are one of the most amazing examples of evolution in our whole body but seeing detail isn't their strongest point, what they are very good at doing is helping to make your brain think it sees what it wants to see. In short, they are an analogy tool which has physical limitations neither you nor I has any control over.
Its cool if you don't want o believe that, as I said, our minds are designed to make you believe whatever you want but that is the truth, unless you have normally very bad eyesight or your nose is up against the screen, you wont notice the difference.
HDR on the other hand which isn't typically played with 1080p content makes the situation very different. As does having 60+ Hz displays. OLEDs make a huge difference as does how the RGB components are arranged.
Normal folk don't sit with their eyes glued to the screen but if you don't do that, you wont see the physical pixels. Its all good if you think you see more, and perhaps you do have dodgy eye sight that allows you to see more, but the average is 20/20 and most folk wont actually see anything different.... at a normal distance away
as I said though, the HDR is truly amazing, I cant stress that enough.
BTW, I do have the XZp and I have a huge 4K Samsung TV. Absolutely love the large display, you wouldn't be able to pry it out of my cold dead hands
Did you finish your diagnosis? So according to you people who notice the difference between 4K vs 1080p on a smartphone have a bad eyesight, while the others don't. Alright...

You can't understand that it is better to display a 4K video file on its native resolution screen, than squeezing it on a lower resolution screen. Sure the size of the screen matters but this doesn't mean that in a smaller screen it isn't noticeable.

yes, that's exactly it, but you will notice I said that it would be bad in everyday life. ie you don't have 20/20 vision.
If I render a 2160 image and display it on my 4K panel then render a 1080 image and display it on my 10800 panel then view it from a normal distance, you cant tell the difference unless you get up close.
ok, I can see this is slipping away from you so ill try change of tact.
If you sit in front of your 1080 screen and look at your desktop at arms length can you see the individual pixels? nope, I sure as hell cant, not unless I have major eye sight issues that magnifies everything, So what makes you think you can see 2160 image pixels? you cant. which means any detail within those pixels that you cant physically see, is lost. It doesn't mean you cant see the image, only that you can only see a grouping of pixels.
Or perhaps another way to look at it. if you lie on a beach, you might be able to see the individual sand grains by your head. but I bet you cant see the individual grains of sand by your feet. You can still see the sand, you just cant physically see the grain.. Its the same with phone screens only significantly more challenging because a grain of sand is typically between 0.1mm and 2mm.
on the 4k display on a phone that has a screen size of 5.5in, that works out that each individual pixel is just 0.03mm wide
that makes a 1080p pixel 0.06mm wide.
now tell me, if you had two pixels that size sitting right next to each other in front of you by about 30cm, are you honestly telling me that you could clearly see both separate pixels? nope. you wont and that is on a static image, never mind a moving one with Noise and compression artefacts in it.
That is the physical limitation of your eyes, your brain then does the rest and if your adamant its better, you will always see it being better. But I bet if I did a blind test on you, the results would be interesting for you to read
its cool tho, as I said, if you believe its better than that is all that matters, you are the person watching it, I just wouldn't want people on here expecting big things and being disappointed if it doesn't live up to expectations.

Look doctor what you said is true for printed images but not for the motion picture videos. Or when you use high res images and you zoom at them. If you have any eponymous scientific research that proves your theory then post it here or i will never take your opinion into consideration.
But even then do you believe that the film industry should going backwards and shoot at 1080p in order to satisfy the majority of smartphone manufactures?
Do you thing that it is convenient for any person to convert their 4K videos to 1080p in order to use them on their smartphones?
Also what type of resolution should they choose the smartphone users with QHD screens?
Do you thing that the downsampling code out of the 4K resolution, that Youtube and other online streaming services use is good enough to be presented on a 1080p screen?
If other smartphone manufacturers in the future adopt the 4K resolution and see you praise them for that, then i will put everything you said in your face. But to see you underestimating this excellent piece of hardware in order to justify others inability to compete, this doesn't make the others look better by any means.
in terms of pixel size, it doesn't matter if its printed media or video, in fact motion picture makes the difference between 1080 and 2160 even less relevant on a small screen because you cant focus on a single area for any length of time. But you didn't answer my questions, if you sit at a computer screen at 30CM distance, can you optically distinguish one pixel from another without magnification aids? this was your test and I'm throwing you a bone because on a computer monitor the PPI is significantly lower than on your mobile device!
4K on small screen, anything less that 50in for the most part, is the worlds latest lie in order to get you to buy something new that is the untenable true in it, when 3D failed miserably this was the latest thing as it happens they also released HDR which is a monumental improvement which makes the display look amazing.
at a typical distance from a tv set, if you have a screen of less than 50 in you will need to sit within 3 feet or there about to actually, physically, see the difference, ALL other perceptions are just your mind making stuff up to make you feel better.
This is also why when you go shopping for TV sets they get you as close to the screen as humanly possible, because it looks fantastic, but in reality ya don't sit that close.
same is true of any display, you just need to scale it down.
There are numerous other considerations to consider when talking about image quality, bitrate ( compression artefacts), compression algorithm, FPS, Display refresh rate and yes of course Resolution, but resolution can only help if it fits within the physical limitations of our eyes.
As to why the movie industry files in 4k or higher, well, there is a very good reason for that and that is because its typically shown on a 70 FOOT screen, a screen that is typically meters away from you.
however don't take my word for it, this chap has summed up what is actually pretty complex in a nice easy to understand manor.

read that, its a little dated but then our ability to see hasn't suddenly improved. the important part to read and understand the 0.4 arc minutes which gives us a theoretical maximum discernible resolution of just over 4k but ONLY if its so close to your eyes you can barely focus on it!
BUT is saying all that, as I said before, if you believe its better then that is all that really matters but I just strongly advise people looking to buy the phone not to expect mind blowing images because in reality, it physically cant do it.... unless its on the end of your nose.

This article scientifically proves that the legally accepted norm of 20/20 vision only asks for 876 ppi/dpi at 4 inches (10 cm).
At 1 foot (12 inches = 30cm), is about 720 ppi/dpi.
Only at 2.5 feet (76,2 cm) is about 300 ppi/dpi.
http://wolfcrow.com/blog/notes-by-dr-optoglass-the-resolution-of-the-human-eye/
So the required pixel density for smartphones is between 720 and 876 ppi/dpi because you hold them 10-30 cm away from your eyes.
The 300 ppi/dpi pixel desity applies only for computer monitors because you are siting at least 60-70 cm away from them.
The myth Steve Jobs created about "magic number right around 300 pixels per inch" for smartphones is officially debunked!

I don't seem to have much luck getting UHD content to play any higher than 1080p on the Amazon app. The only thing that has ever played in 4K was an episode of The Grand Tour.
