Note 3 versus 4: subjective screen comparison - Galaxy Note 4 General

One of the things I have wondered about the Note 4 is how much better the QHD screen was in real-world comparision with 1080p. We all know the specs are amazing but does it really matter in everyday use?
When I played around with the Note 4 briefly I was astounded with the quality of the sample QHD videos. However in general use it didn't seem that much better than the GS5 next to it. I didn't get the opportunity to do web reading where QHD might matter.
So my question to those with the Note 4 particularly for those who have used the Note 3 as well: how much better is the screen in actual real-world use based on your subjective experience. Where does it make the most difference: videos, gaming, web reading ?
If you have done side-by-side comparison of the Note 3/4 in any of these activities that would be especially interesting.

Screen is better in everyway yes you mostly dont notice higher res but with small writings you can definitly see the sharpness. But mostly screen is better in other ways like better brightness better colors

Looking to purchase Note, what pros and cons.

Hi
I am a happy Galaxy S I9000 owner. And I would like to purchase my next cell phone model. I am looking to Galaxy Note. Would you kindly post your impressions and any pros and cons.
Thanks
Cheers, Darius
Pros - too much to write about (don't have enough time now)
Cons - There's no return to other Smartphones. It's just too addictive .

Thanks for prompt reply
Pros:
- Huge, beautiful, detailed screen
- S-Pen (I use it pretty frequently for taking notes, screenshots etc.)
- Great speed
- ICS coming
- Great camera
- Did I mention the lovely screen?
Cons:
- Notification LED missing (I got used to it on Desire)
- For some the screen might just be too big, so try it out before you buy it.
- You really won't like smaller screens after a few days
Oh and the phone has some difficulties with the black color in films. As I read, it is because the screen has 24-bit color depth, which is uncommon yet amongst programs (to an expert: please correct me if I'm wrong!)
Feel free to ask, if you have further questions!
Hello Darius, I've owned both the SGS1 & 2, and now the Note. I had some misgivings about the Note too, especially since the demo units at the local Samsung shops felt laggy to me. But I did much research and finally got the phone, and it's one of the best decisions I ever made.
Pros:
Huge size makes browsing, checking email and ebook reading a breeze. It's large enough for me to decide to sell off my rooted NookColor as this is much more flexible, portable and has much better features. I find it easier to hold the phone and take photos because of the size, as compared to the SGS2 which was too thin for me to hold comfortably.
Doesn't matter what conflicting information there are out there about pentile display, the screen is beautiful and the colours lovely, not over-saturated like SGS2. Banding is also much better than what the SGS2 suffered from.
Battery life and camera seem comparable to SGS2, if not better. No issues with dead pixels, pink spots, green whatever...I did notice that the display is a tad uneven with a flat grey wallpaper/background, but that was true of my SGS2 as well. In real life I do not use an even toned grey wallpaper, so that doesn't bother me at all. And it's pointless to get all stressed out over little things like that as my life is exciting enough.
The s-pen makes taking notes on the fly so much easier and cooler than digging around for a pen to write on your palm! I like being able to take screen captures too. Hopefully my artistic career will take off because of this phone. Nah...just kidding!
Cons:
Huge size means the self-conscious people may feel somewhat clownish with this. You'll have to put up with a few--not that many--stares, rubber necks and looks of horror from the unenlightened. Those who had owned Palms or are suffering from long sightedness will doubtless praise you for your gorgeous new gadget. Those who wear tight jeans may not be so crazy about it.
It comes with bloatware that slow down the phone (at least for speed freaks like me) and take up space. Thus you may need to root--please read extensively before doing so--in order to freeze or delete the bloatware. This is subjective as some people don't find the bloatware an issue, but I've always rooted my phones and my hands get itchy when I don't. Perhaps once the official ICS comes out, I will no longer need to root as I understand that you can easily delete unwanted apps.
Some apps are not meant for phones this size and may not take up the entire screen, or will look a little soft. So far these tend to be games. It's not a deal breaker for me because I don't play many games and can easily look for alternative games.
And the greatest problem, I feel, is that I may never settle for a smaller phone in the future!

You're most welcome. Uh...I added a bit more info after you read and thanked me.
My pros and cons are at my blog, AndroidNZ.net
So far I've written about 8,000 words or something in my review, and the last part is nearly done and currently coming in at around 4,600 words.
If you really want to know the pros and cons in detail that is.

I mean...pray that you won't get one with Dead Pixels like the one that I got recently
I heard there are some screen quality issues with the Note from this forum but didn't think I would be unlucky enough to get one. But guess what....
But hey...I'm sure you will be luckier than me....and apart from that....it's a GREAT device
Well the only issues you would face are with the screen and nothing else. If you are buying at some store do sure to take "dead pixel checker" or "screen test" software with you (in ur older phone). You can transfer em to the new phone via bluetooth and test the screen.
Otherwise U can go to the service menu and check the RGB screens for any dead pixel. Best way to check for dead pixel is to lower the brightness to 0% and take the phone in a dark environment if possible and look from a distance of about 5 inches. Otherwise its really hard to make out dead pixels in bright lights, but if they are there and you are watching a movie at night in the bed, u wont be too happy to find em. As others have said the screen is uneven on gray color. Do check out the grey color and see if there are any smudges and try to see them on other normal screens. If they are not there then all good.
Regarding dead pixels till now, only white stuck pixels have been reported (me a victim as well). And stuck pixels (particularly in this phone) are visible only on grey color. If you have any more doubts dont hesitate to ask, would be glad to help !!!
I have had both. The biggest decision is the screen. Its fantastic to look at and work on but its massive to deal with. I'm sometimes a little scared I may drop the device and one handed is nearly impossible - which is generally not a big deal except for taking pictures sometimes. Jury is still out.

Thank you everybody for sharing. I have already exchanged my SGS to Note. Very happy. Seems to be no dead pixels.

most super amoled srceen does not have dead or stuck pixels, is this because of the density of the screen using the 1280-720 screen, also to hijack the thread, what will ppl consider between the note or galaxy nexus, why i'm asking, i will be getting either one next week, so ppls opinion would be great.

[Q] Missing OIS in Turbo's camera?

I currently have a Nexus 5, and I'm thinking to get the Droid Turbo, preferably the international version that would be announced this week (hopefully). I would say I'm between a normal and advanced user, not development or heavy stuff, just the normal usage and some ROM/Kernel flashing when bored.
I have read tons of threads here in XDA and also in other forums about camera, battery life and all the Turbo features; I found many opposite opinions across people about camera and battery life, but my question is more oriented to know if the missing OIS feature in the Turbo's camera mean low quality in pictures or videos.
Also, I don't really know how much the OIS feature helps in taking pictures or if there is any notable difference between having a camera with it or not for pics; I'm so not worried of videos because I hardly record one but I'm wondering if it is useful when in any way when not taking videos.
Thanks to everyone.
OIS does help in certain situations. From my understanding its in lower light enviorments with a longer exposure times. Im not sure its a deal breaker though. I think its more helpful on expensive cameras with higher zooming capabilities. When your not zoomed in its much less useful. Its also more helpful on much heavier devices that are hard to hold still. Overall smartphone cameras are for daily photos, quickly capturing moments. They will never be professional level picture takers. I can say the camera takes awesome pictures for me so far. I havent had issues without OIS.

Thanks so much for the answer, I'm not the guy who want the best camera on my phone, but at least I want decent pictures, and I think my Nexus 5 already make that, so I hope the Turbo could be the same or a little better.

I see no difference in Gaming (from the Note 2 to Note 4)

Was testing Asphalt 8 today, and noticed that gameplay was more or less the same as it was in the Note 2. Seems like we're reaching a plateau in the world of mobile technology.

Isn't Asphalt 8 locked at 30fps?
Anyway,youve got all those extra pixels to render with the Note 4,it will stress the CPU/GPU more. I believe Annandtechs tests showed that running the S805 with a 2k screen gave similar performance to running the S800 with a 1080screen.
I forgot to think from that perspective. Seems like the game is locked at 30fps. I really see no use of those extra pixels and thus unnecessary battery drain though I've achieved over 3 days with the standard battery.

There's only going to be more pixels, wait for 4k phones at the end of this year!
4K on a small screen is crippling when think in terms of battery drain. Wonder what the future of battery technology will bring to the table.

I feel you. I've also upgraded from note 2 (which is now with my wife). Really, other than a better scree/ pixel density, I don't see much in the Note 4. May thinner profile/ better build quality. I still feel that the camera is downgraded (except for the fact that the note 4 has better control over spherical aberration). I really miss the macro mode in the note 4. Gaming, as you already mentioned, isn't any different.
I see the camera at fault as well. Not defective, but in low-light, tends to get grainy without the flash. Perhaps I haven't taken enough low-light pictures w/o flash with my Note 2 to notice this. For outdoors, the HDR modes works great with the Note 4; I do like the ability to enhance the photo, edit, and get creative. Software, there are some things I miss, especially Quick Glance, and features in the Galaxy S4, which I never got to experience, not that those software features are gimmicky.

You may need to get your eyes checked lol massive difference
Asphalt 8 is not locked at 30fps, the note 4 Exynos during game gives around 60fps while Snapdragon 45fps.
The Note 3 Snapdragon is around 30fps.
You can test the FPS whit the app "Gamebench". It needs root.

Lodix,
Thanks for the plug mate Just a note - GameBench doesn't require root - you can launch it using our desktop launcher just fine If you have root we can launch it for you.

Confirmed 60fps. The massive difference is only on the display quality, not the game play; subtle differences only.

LOL. :silly: I was just basing this on various articles I came across on Google, can't confirm real world value, unless I perform the diagnostics. Though Antutu does mention my overall score to be 49,888. My Note 2 only reached 18,000. Seems odd that the real world performance difference is subtle. Forget gaming, my Note 4 does feel a lot smoother and I can keep more apps running in the background compared to the Note 2.

dude Note 2 with mali 400 can play almost every game around 30fps @720p but Note driving x4 the amount of pixels which needs a lot of power + adreno drivers sucks and games always run better on non adreno GPUs like mali , Powervr
anyway i don't think any android game support 1440p or even 1080p natively they are just get up scaled i think which is just wasting of gpu/cpu power if android allows user to change the res of the game like windows that would be great

That's why I miss the Mali / Exynos combination. Hopefully, my next Galaxy device will feature this.

Can you share a screenshot ??

Seeking feedback re: camera quality... just how bad IS it?

hi folks,
been excited about this device since it was announced but have been real disappointed by the negative feedback on the camera. still considering the purchase but am worried i'll regret it. i am coming from the z3 (non-compact) so i have difficulty gauging just what people mean when they talk about, in particular, poor low-light performance. just how poor are we talking? like you can't shoot indoors at all or just that photos in dark areas will be grainy? will it be at least as good or better than my z3?
there have been some really helpful posts in this thread and i've read a range of opinions from "it's actually quite good" (see this android central review) to "i am returning this piece of garbage immediately" (various forum posts).
from what i can gather the device is a winner is most other areas (including all the ones that matter to me) but this camera stuff is a real sticking point. i mostly only use it to take pictures of my kids and tbh the z3 does a mostly good enough job so i'll probably be happy with any improvement at all.
thanks for any guidance you can provide, low light samples would be super helpful as well.
I think it takes better pictures than my X Performance, Z3, or Z2 ever did. I haven't noticed any grainy photos. I don't use auto focus a ton but when I've tried it the photos turned out fine.
GSMArena has quite a lot of sample pictures for various scenarios.
It will be a step up from the Z3, especially the speed (I have a kid myself, capturing the split second moment is now possible).
But if you want the absolute best camera on a smartphone, then this is not the phone you are looking for.
Also, from the same review, they have a photo that quite clearly shows the distortion people were complaining about, including me. Note how the building looks warped.
The same distortion is actually present in all photos, but as you can see from the other photos, one would be hard pressed to actually perceive anything strange about it thanks to the way our brains work.
Chances are you'll never notice any distortion for the majority of photos you take, unless you happen to have a grid-like background or object to magnify the effect.

Distortion is horrible, but only seen if some photos.
Overall the camer is good, not the best like from note 8, pixel2 or iphone 8 but still ok

I agree. Overall camera performance is better than in Z3c, especially at low light and in department of focus speed.
But when you take a photo when distortion is visible, it makes you sad But in my case it was ~5% of photos.
Distortion is not really noticeable to me, but Sony's smoothing algorithm is.
Often, lots of detail is lost it parts of the image when viewing at full res.
I'll experiment with lower resolutions to see if it's still as agressive there.
Other than that, the camera is really fast to focus and make shots, and HDR seems to work reasonably well.
Haven't tried manual mode yet.
Super Slo-mo is a very interesting feature to play with.

note going 120hz

https://www.youtube.com/watch?v=LzC_kkbFTHQ
just came out today,? is will their be a mod to put note 8 120hz or im i going to hear the magic words ...no its hardware thing?
Um ... why , 2k screen at a 120hz would take some power. Plus with small size really wouldn't be worth it. High fps really only matters in shooters on pc. On a phone there are too many weak links to make it good for games that would call for 120hz..

Hz (refresh) is not the same as fps (framerate)...
And higher refresh rate actually makes everything smoother, including simple animations, etc. For example, I have a three monitor setup (2 x 60hz, 1 x 144hz), and you can easily see the difference just by moving the mouse cursor. Much smoother and easier on the eyes.
Razer includes a 4000mah battery...if Samsung bumps up the Note's battery capacity again in the future (and/or introduces further OS optimization for increased efficiency) then it could mitigate any additional draw in power. Personally, I think a Note 9 or 10 with faster refresh would be sweet

Yes it can be done, the Razer just did it. Not likely on the Note 8 though, but can't really say for sure. I do know that the refresh rates of some monitors can be overclocked, but it only works up to a certain point (much like ram or processors). So even if it were possible to increase refresh on the Note 8, I don't think it would be anywhere the Razer's 120hz. Happy to be corrected if I'm wrong though.

Just found this article which explains a lot:
https://www.androidauthority.com/120hz-displays-the-future-or-just-a-gimmick-782717/
Sounds like the refresh rate on the Note 8 could theoretically be increased through software alone, but that it would likely introduce issues such as screen tearing, etc. In contrast, the Razer's panel (for example) has hardware technology to reduce or eliminate these types of artifacts. So I'd say yes it could techically be done on the Note 8 to some degree, but even then the results wouldn't be great. Better to have the hardware that makes it work right and delivers the desired/expected visual experience.
OLED is not able to do those high refresh rates yet.... Its hardware
Even if you got it to work it would absolutely kill the battery and if/any games even are optimized for 120 hz is another story.

You can see the difference if you have the video/game that uses it otherwise it's number theater . I would venture most folks couldn't tell between 60 and 144 unless it was in action. 24 to 60 yes, but beyond 60 is splitting hairs. Also on the small form factor of a phone, with the control latency of a phone not sure tour getting bang for buck . I am aware that Hz and fps are different ,just as I am aware that using different refresh rates in a triple monitor set up is just asking for problems as well. To me it's just the same as THX speakers on a phone or Dolby Atmos on a phone, yes they're there but it's more like a gimmick because of the small form factor. I am also biased towards pc gaming , and could not imagine playing any serious shooter on a phone, just like I couldn't do it on a console either(but at least consoles have the horsepower now).
My biggest fear is this catches on and Samsung ditches it's Amoled displays for LCD just to get the specs for the next phone.

No as I said you can see the difference just moving a mouse (or watching movies, etc). Also, no issues at all in a triple monitor setup with different refresh rates, so long as you know what you're doing. Obviously if you try and play a game on 3 monitors at once with different rates then you're asking for trouble lol. Anyways, moot point now as OP's question has been answered.
Animation in android
Can the animations and UI in android currently even run at 120? Are they not rendered at or around 60fps?

I wouldn't put too much credit in this article. They seem to be sort of talking out of their asses on this.
Adaptive display technologies reduce screen tearing yes, but their main benefit is the reduction of resources. Allow me to explain.
Your free to correct me if I'm wrong but this is my full understanding.
When a screen displays an image it has to get told to display an image. However, it's not quite as simple as the CPU saying, please display an image.
The screen will continue to display an image until it's told to Change to a new one (think of when your PC freezes. This is why the image can sometimes freeze. The display adapter has stopped sending new images to the monitor).
So what happens when your computer is creating a new image, 1000x a second? Well, it would tell the display to "display" 1000 images in a single second, even though it's only capable of let's say 60 (this is where 60hzcomes from) this creates the tearing effect. To combat this there are controls we can use, Such as vertical sync, where we can just Pull an image from that 1000 image pool when we want to display a new image. For example, your phone might tell android, since it is running at 60hz to just pull a new image from that pool once every second. We could also limit the software to only create a new image once every second as well to combat this. The problem with these is they require CPU cycles. And they have an impact on the memory, with the frame buffer holding that 1000 count image pool. Ideally went want the CPU to only worry about creating an image when we 'want' one. So that it can move on to the next process in it's Queue.
With adaptive display technology, we can 'sync' these two numbers without creating a significant performance impact, and because we have synced them the overall smooth transitions require less motion smoothing, or blur effects that alot of movies might use to help create that clean look (This magic is why movies at 24fps look fluid). When it comes to Android, 120hz vs 60hz would most definitely be noticeable, so long as UI transitions and the OS itself had animations that could display 120 different frames. Currently I think that it does not. Also, let's be honest, until the hardware starts supporting it, android won't support it. We are starting to see that support now, in the Razer phone and in some Sony phones.
I am unsure of the currently refresh limits of OLED. I do know however that OLEDs response time is faster than that of LCD. Response time doesn't directly effect refresh rate, That would be the job of the display controller, or whatever that strip is called haha. Response time is important though as it'll determine the quality of the images being displayed at higher refresh rates. Which would be the significant factor in whether you would want your display running at 120hz or simply 60hz
Also... Before anyone chimes in, with "you can't see more than 60 frames per second" your wrong. Don't bother. Sorry, but you've done zero research.

So samsung Note 8 runs on 60 GHz?
And razer runs on 120 GHz

No, just Hz. And yes, 60 &120. Did you join xda just to ask this question ?
