720p Displays - 'Cool Factor' or a practical improvement?

I’m going to be buying a new phone soon. I’ve been eyeing up the Galaxy S II but I thought I might as well wait and see what is announced this month. One thing that all top end rumoured phones have in common is a 720p display. I have to admit this alone has tempted me to wait. But then I got to thinking, aside from the ‘cool’ factor. What benefit in the real world will a 720p display bring us?
The two main advantages that I can see are improved PPI and the obvious advantage when playing 720p videos. But a higher PPI means more processing power, which in turn means lower battery life. Also from an admittedly purely lazy point of view it means having to zoom in further to be able to read text.
A 720p display will now mean that 480p videos on youtube and the like will be upscaled and won’t look as good. ‘Just choose the 720p option’ you say. Fine, so long as you’re on wifi. Until 4G hits and is widespread (which in the UK is going to take a while) it will mean longer waits and buffer issues.
Yes I’m nit picking but I’d genuinely like to hear your thoughts on the pros and cons of a 720p display. I know there will be many more I’ve missed.

i see it from 2 sides....
720p = really nice picture quality
720p bad for some apps/games, which might no longer run properly, unless fixed, or some how the hardware can auto adjust the resolution to stretch it to fit.
720p can be a bit of a pain, if some Apps/Games developer decide to use too small of a touch area, due the larger dot-pix available in the 720p area
that also means DVD quality or lower quality videos played on the 720p will look like blurry or smeared, that can be fixed with software/hardware correction, like games.

^^ All that.
Plus, I don't really see the need for a 720 screen that's around the 4" size. Do you really need pixels that small? They'll be smaller than photons if we carry on like this and then it'll be reality that'll have to catch up with our tech
Personally, I wouldn't hold back for purely that one feature, but who knows what else is round the corner. Get a phone and let it be the best for a few months and then slowly drop down the list. As everyone always says, there's always something better coming, and if you waited then you'd never get anything.
Incidentally, I do have the SGS2, and it is REALLY nice

well definitely 1080p will be around the corner as we already stepped into the 720p kingdom
so 1080p on a 4" display would not be a long wait, but it will really make you think, what's the point of cramming so much in such a little screen
i can see 1080p to be a normal thin on a 10" tablet, but on a phone... that's a bit much
i do hope they don't go beyond 720p on any screen smaller than 5"
imagine running Windows Vista/7 on 15" wide LCD at 1080 (there are many laptops that are actually like that) it's soooooo eye strain-ful, it literally kills the eyes
i always down set the resolution back to something more readable to not strain my eyes

Do you need your reading glasses as well, so you can find your pipe and slippers?

i don't wear glasses, and i intent to keep it that way, reason why i prefer an easy reading, on 480 vs 720
on 720 i'll have to probably the the font size twice as big, to make it easily legible when you are in the car, bus/subway, or walking
no i don't get dizzy reading while doing any of the above
many people can't read if they are in a moving vehicle
probably due the same relevant issue about having to scan the text in a small device and straining your vision, while trying to keep an eye on the road and not crashing

I agree with you, therebisbreally no reason to go above 720p resolution on small smartphone devices. I myself notice my eyes begin to hurt after more than thirty minutes or so of heavy reading on my Sensation. Now I know my Sensation does not have 720p but I am just saying the size of the screen and the text on that screen is no doubt a strain on the human eye after extended reading done on the device. 1080p is definitely so,ethimg that should just make it to the larger tablets and not smartphones.
Oh and yes actually paying attention to the road while you are driving is a highly recommended activity lol.

This is just plain wrong, low resolution video will look just as good on 720p displays.

Maybe i miss-understood your question, but i am using the Galaxy SII
I never had any screen / resolution issues

Well,first off,let's not forget that Android supports changing the DPI in build.prop(I think-haven't bothered in a while).I don't think manufacturers will leave 220-240 dpi of the current devices on 720p devices,but they would rather pump it up,so that everything stays the same size,but is just crisper.That's just my thought though.
On another note,lower resolution videos won't look worse at all.Resolution in that aspect is irrelevant.The same way that you can play a 720p video on a 480p screen without problems,you can do the opposite just as well.Unless some manufacturer decides to f*ck it up with upscaling tricks and stuff that will defo make the image blurry and ugly.
The only really valid argument on the topic,in my opinion,is the possible lack of processing power,especially when it comes to GPUs.We even saw the Mali MP-400,the most powerful GPU on a PHONE (DON'T SAY ABOUT THE A5 IN THE iPAD!!!!) to date,struggle to keep up in the case of the Galaxy Note's resolution.If the next gen of SoCs doesn't improve quite a lot in that aspect,we'll see some performance drops for sure.Not to mention the worst thing,the losses of battery life in case that extra power is met.Not that I mind about battery life as long as it makes it through the day,but many many people do.

Do any of you guys know the p in 720p stands for?
It has nothing to do with resolution, which is what you are all trying to talk about.

progressive, opposed to the i of interlaced.
Technically 720i use half the vertical pixels for each frame.

Confusion about display quality

Hello, I keep hearing people saying that the screen of the Note PRO 12.2 is very nice. Is it only for viewing photos and watching movie? I tried a Note PRO 12.2 in another store. Again, they did not allow me to connect it to the internet. From Magazine MX, regardless of font size, I can see letters and numbers made of large pixels and the edges are not smooth. Is this a rendering problem or the dpi problem? Can this be fixed without rooting? Does this issue show up when I view pdf documents? As they did not allow people to connect to the internet, I could not test. Thanks.

At what is considered a normal viewing distance no pixels should be visible. The screen displays at a true 2560x1600 resolution. If you were seeing jagged "large" pixels you are probably too close to the device. There are only one real occasion you should see pixels (possibly). This is when either viewing colored say blue text against a fully saturated solid colored background (HIGHLY UNCOMMON). Black and white text will render 100% perfectly and any full color images will also render perfectly. Understand the reccomended viewing distance for a screen this size is close to 18-24 inches

Thanks. I saw the large pixels under magazine MX. I could not test other applications. On both devices (from different stores), as soon as Handcom Office was launched, the app got terminated automatically. Couldn't test browser nor pdf as the stores did not allow wifi connections. The most obvious are the large numbers that made up the clock (white numbers with blue background). I could see the large pixels even at an arm's distance. I don't remember exactly but I think I also saw large pixels on letters that made up the calendar under Magazine MX (white numbers in green background). As I flipped to other pages, I also saw large pixels.

It's definately not that bad. If you look for it you can see pentile artifacts but text is plenty sharp and I'd much rather have this display than my wife's iPad 2 for example. Sure a retina display on an iPad 3/Air is great too but this Note Pro screen is plenty good enough for me.
I give you credit for your fortitude man, in the few months you've been trying to decide I've purchased one, lost it in an act of utter stupidity and then purchased another LOL.

I still cannot buy the LTE version in my city. I will travel at the end of next week. I am going to make the purchase. I have to choose between the LTE version of NOTE PRO 12.2 and the LTE version of 10.1 2014.

If its about black and white text it should be amazing. Pentile only requires 2 subpixels to make a black line. Rgb takes 3. So the pentile actually will produce more lines at the same resolution. And for black and white text reproduction is 100% flawless. Text should be much better on the note is what im sayin. Well nearly identical considering lower dpi.

No complaints on the screen here, I also have the Note 10.1 2014.
The screen is great at normal using distance. People who hold the screen to their nose complain. It's got a lot more pixels than my 27" desktop monitors that's for sure.

[DISCUSSION] [OPINION] Samsung should've made the S8 phones in 16:9 screen ratio

After using several onscreen navbutton phones in the past and having this S8 for 5 days now, I see almost no reason as to why the 18.5:9 screen aspect ratio decision was made.
It would still have a big screen, probably close to the S7 Edge size.
The only thing I can think of is that Samsung is used to creating apps for 16:9 ratio screens because previous phones had physical navbuttons. Maybe they didn't want to have to mess with that and just put the navbuttons on the screen and increased the length to accommodate the extra buttons taking up space on the button; still allowing them to make 16:9 native apps. I just don't like it. It makes for an awkward Android experience, especially with unsupported apps.

I disagree. Based on the number of pre-orders alone for this phone, it will soon become one of the most popular android phones in use. As use increases, more companies will fit their formatting to the unusual aspect ratio. The fact that the G6 also has this aspect ratio (and yes, I know it's not exactly the same, but close enough) means that there will be more impetus for developers to accommodate the screen. I think this is a big step forward in the mobile phone industry, it just needs to take some time for the rest of the industry to catch up.

The preorders aren't an indication of the abnormal height of the phone, but the infinity screen itself. They could've kept it infinity just the same with 16:9.
Why do you think this is a big step forward? What purpose does the super tall phone serve in your opinion?
Hoping we can have a good discussion.

Disagree. This should be the standard much more comfortable than s7 edge. Not because of the edges but becaus3 of the slim side ratio. Would not buy another 16:9 phone ever again

I really don't know why people are *****ing about the aspect ratio. With modern Android you don't notice this at all because the developers know how to deal with constaints of interface elements. Now you can see one google news more. You have more space above the keyboard. List views have one more entry. Whats the problem with that? Maybe there are apps that are incompatible but I have yet to see one.

To be honest I've not encountered any issues worth talking about, related to elongated screen. If there is software that can take advantage of extra screen (and there will be more coming soon), great, if not there are bars on the screen just like if I had larger bezel (or like watching 4:3 program on my HDTV). Actually I have hard time telling where the screen ends and bezel starts. I was expecting to miss physical home button, but since it is now permanent part of the screen and it is still there, except invisible, it doesn't bother me at all. And benefits of longer screen are great: finally we can have 2 programs display properly on the screen at the same time, typing is much easier, with more text displayed, web pages show more, with less scrolling, most cinema movies are shot at 1.85:1, some are as wide 2.39:1 etc.

In my opinion.. the only issue with the weird aspect ratio is that it fools some people into thinking their screens are so much bigger than it actually is. The S8 for example has only 2% more screen area than a 16:9 5.5" screen while the S8+ has 17% more screen area. The regular S8 screen is also narrower than screen on iphone 7 plus.
If you are going from a 5.5" 16:9 ratio phone like the iphone 7plus.. the regular S8 WILL feel like a smaller screen in comparison.

You can keep the exact same slim side ratio and reduce the height of the S8 to get roughly the same size screen as the S7 Edge in a much smaller body. Not sure where you were going with that.

I'm actually quite happy with the screen.
the extra wide/tall screen helps create better immersion in 3D games, improves field of vision in VR, and compensates for the screenspace now lost to the onscreen buttons(or in my case, my physical keyboard)
the slimmer design also makes the phone more comfortable to hold, the S8 has the perfect width for me.

You made a few good points:
1. Multi-window works better
2. Bit more room to type
3. More webpage for scrolling less
While those are good, if I was given a decision I'd still take a shorter phone. I personally prioritize the size of the phone over many other things.
If this phone was released as 16:9 with a 5.5" screen (same as S7 Edge), it would be slightly larger than an iPhone 6/7. Which is insane because their screens are only 4.7". To me the iPhone is the perfect one-handed size phone with every other hardware being not so great.
The S7 was a 5.1" phone and the natural progression could've been to a 5.5" 16:9 phone in a smaller body than the S7 with the same size screen as S7E. I really think they went with 18.5:9 because of the apps. I bet you this screen would be 16:9 if you chopped off the navbar softkeys. Could be wrong though.
I'm really just nitpicking

I've actually enjoyed the taller screen. I went with the plus and am still able to function just as I was able to on the s7e. It gives you an option to expand apps that aren't already expanded to take full advantage of the screen, and watching video with bars on the side isn't a big deal to me, because as was said above that would be the bezels on an older s model phone and I prefer(love) the look of this one. An iphone may have the perfect ratio, but the resolution doesn't compare to these screens and that's what I'm looking for more than the ratio, just my opinion of course. That bixby button on the other hand...

Which video apps have 4k playback enabled?

Can't seem to find this info. Is there a list anywhere? I assume, the Sony video and album apps work in 4k. YouTube and Amazon Prime too. After that I'm not sure. Vlc? Netflix?
Thanks in advance.

Netflix is a no, not supported yet! vlc should work fine. And 4k pron is epic lol

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).

As far as I can tell, it does not. Just HDR at the moment.

I have premium subscription. I only see a box for HDR on the movies that have it and movies without HDR have only HD box so that's all.

Last I spoke to netflix support the guy checked and said they're updating the code in the app to make Uhd 4k compatible on our xzp. Can't wait as already hdr looks at amazing.

The Amazon Prime video doesn't show either if a video is 4K HDR or not. How can we know it?

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... [emoji16]
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.

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.

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.
http://wolfcrow.com/blog/notes-by-dr-optoglass-the-resolution-of-the-human-eye/
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.

Considering returning my Note 8 for a galaxy s8 plus

I posted in the note forums i thought i would see what replies i get here as well
I loved my note 7 (nice rounded edges samsung oem screen protector etc) This phone just feels ...well HUGE... in pocket as well as in hand... I am realizing im not using the spen at all really (other than to send sparkly messages to my wife) since i got my ipad pro and pencil for sketching. For some reason this thing feels immense in my front pocket and heavy.I read at night and holding this phone can be cumbersome at best.. I love the screen and playing games on it but for pretty much everything else its not what i expected. I went to best buy and held both phones at the same time and the s8+ feels so much better in hand with only a .1 in screen difference (i cannot even notice) Am i crazy for exchanging it for a S8+?
ps i like the dual camera live focus thing but for me personally its not that important. 99% of my phone pics are point and shoot and share to a friend or social media..
I had a s7 edge up until 2 weeks ago when i picked up the note 8 and it just feel gigantic.. I wanted a bigger screen because i wear reading glasses but the ergos are not nearly as nice as my old s7edge or the newer s8 and s8 plus.

Do you want to trade? Is your phone unlocked and what carrier are you on? My phone is unlocked by T-Mobile due to military status and it is in new condition! Message me I'm serious.

there's your answer. and you'll get a bit better battery life with the S8+

I'm sure a lot of people will trade their s8+ for your note 8. Just ask them to add some cash for the difference.

S8+ is the same size, with no SPen and a single camera, and 2 gigs less RAM. The battery is marginally bigger, though. If you want a smaller device with the same basic experience, go with a regular S8.

Just a quick follow up i got my s8 plus and I'm in love!!!! It's so much lighter and more comfortable in hand and pocket.. I'm so glad i switched ?

Not mine ... I have 6gb 128 version. .
I have always since s3 had the notes Note 3 etc... Can't see myself swapping from s8+ this time. Less battery life on the note? Nah - pass.

I agree with your assessment of the two. I did the same Best Buy comparison last week and wound up buying the S8+. However, I will likely trade it in for dual cameras on the S9+. For now, I just wanted the step up from Note 4 and it fits the bill. S9+ will likely be it for a while unless Note reclaims their ergonomics for all. I'm a small person and not going to start carrying a bag around just to tote a phone. Meanwhile S8 was too small and odd feeling compared to Note 4. S8+ is just right.

Personally I hate the aspect ratios they have started using. 16:9 is the ideal ratio and happens to match widescreen video formats exactly. all this 18.5:9 crap just means you have a long skinny screen with less actual space on it. It's amazing how the screen on my old S5 just seems bigger simply because it doesnt have this silly long and skinny aspect ratio. In reality these screens are not actually 6.2" due to this, they are closer to an equivalent 5.5 and really ARE about 5.5 if you want to watch any 16:9 video without cropping it. Using the same logic they have started using for these screen sizes, by continuing to measure diagnonals despite not having a 16:9 ratio, you could make a screen 10" long and 1" wide and call it a 10.5" screen.....but it isn't is it.
That's my only problem with my S8+ (other than the fingerprint scanner placement) and it irritates me constantly. If it was 16:9 (which would also allow a much bigger battery) then it would be perfect. But I haven't exactly seen people commenting on it so i guess nobody else cares.

no I agree with you. once i find a 6" phone with a less stretched aspect ratio AND stereo speakers.. i'd gladly trade my S8+. I'm not a fan of playing games/watching videos with a narrower width but longer horizontals. i wish Google would make the Nexus 6 again with modern hardware.

I actually like the new aspect ratio. It simply sees more stuff then 16:9
Had an s7e before s8+ and to me it's like switching from 4:3 monitor to 16:9 wide FHD monitor.
Only thing I don't like is iris not being as fast on daylight unlocking the phone and fingerprint feels useless here.

I ended up going back to the note 8 !! Even with a case on the s8 plus i was getting false registers on the sides and corners with my big meaty hands... Is will be here Monday. Also in gaming grip or watching movies there note is far superior.. i feel dumb returning it but hey, it was a learning experience and at least i ended up with the better phone in the end

All those guys who say the Note 8 is heaps bigger than the S8+, I own both. a side by side comparison is about 5mm taller and almost exactly same width...
Battery life is pretty mch comparable with both .
I have the Exynos version of both so that may make a difference.

I certainly wouldn't call it "heaps" bigger. The angles are simply awkward for some hands and some situations. As for the weight, a hundred pound person may find it heavier versus a 150 to 200 pound person. Note 4 and Note 5 felt very comfortable. 8 is different. Not bad, just different. Without a doubt, the Note is the better phone. Thank goodness for choice.
