hi, i was wondering if you were kind enough to answer the following:

-camera's autofocus: do you know if it uses a phase detect system -like the s5 or a contrast detect like the note3/s4? i played with a demo unit and it seemed to focus slower than the s5. the specs just mention autofocus without going further into detail.

-compass calibration: is the compass still calibrated when you restart your phone or do you have to recalibrate it at every start via the hardware test mode *#0*#. that's an issue with the note3.

-gps stand alone accuracy while offline: how good/accurate is the gps by itself without cell support? the note 3 was worse than the note 1 in that respect.

thanx for taking the time to answer
[Galaxy Note 4 General] pcman2000:
As far as I know the Note 4 unfortunately doesn't have PDAF. It's using a Sony IMX240 sensor as opposed to the Samsung ISOCELL one, which had PDAF.
[Galaxy Note 4 General] DelBoy:
bladefrost007 congrats mate. There is more and more of us
[Galaxy Note 4 General] bladefrost007:
Thanks del boy. I have a problem antutu score only 35k. Very low. Also i cannot find air gesture.
[Galaxy Note 4 General] JCM800:
When you get time,, could you please play the latest GTA on max settings and see if your 4 can cope with it? Thanks :)
[Galaxy Note 4 General] bladefrost007:
I restarted the phone and run antutu again and here are the results...
[Galaxy Note 4 General] DelBoy:
You mean San Andreas?

Plays fine with max settings
[Galaxy Note 4 General] tmac31:
I checked bluish color turn on demo unit. Its definetly there when change angle abit white goes blueish. But it was only noticible on white i checked with a colored picture it was fine or not noticible

[MENTION=4228208]pcman2000[/MENTION]:

thx for your answer. i saw the imx240 part when it came up a month ago, but i wasn't sure, if the pdaf part had to be on the chip. i thought it might be incorporated as a separate module. thus the question if it's pdaf. i guess it would have been more expensive to build. i wish they would use better quality sensors instead of keeping adding new ones. you had to be lucky to have an accurate (5m)& persistent (>10mins) gps on the predecessors
[Galaxy Note 4 General] markyboy81:
This is also present on my note 3 but I hadn't even noticed it until I'd read about it on here. Certainly not an issue for me.
[Galaxy Note 4 General] :
How is the build quality / look and feel cmpared to the Galaxy Alpha? I was quite impressed by the Alpha, felt like real premium quality to me.

Is there an useful car mode (S-Voice?)?

Sorry, didn't had Samsung devices since S3. ;)
[Galaxy Note 4 General] toadsurfer:
Thanks for checking. Unfortunately on mine it's very noticeable, even on coloured images and especially in video when a slight altering of the screen angle changes the picture from warm to quite green/blue. Bit depressing really as it seems is not a widespread issue and I've maybe just been unlucky with mine. Now I've noticed it it drives me mad though!
[Galaxy Note 4 General] tmac31:
Did you try auto adjust colors option in settings maybe it reduce the issue.
[Galaxy Note 4 General] toadsurfer:
Yeah, no real difference. It's probably just a case of me being picky and my phone being worse than normal, but it is frustrating. No point having an accurate screen if it changes colour wildly depending on small changes in viewing angle. Is particularly obvious when side by side with my s5.

The displaymate review claiming very small colour shift but then the phonearena review stating very large shift suggests there may be a bit of a screen lottery going on. Thinking of returning mine. :(
[Galaxy Note 4 General] tmac31:
Maybe you can check demo units against your device.
[Galaxy Note 4 General] toadsurfer:
Well l went back to the shop and compared it with some display models and they all have obvious colour shifts at even small angles, it's really quite a pronounced blue / green tint that reminds me of the s4. Samsung fixed it in the s5 but seem to have gone backwards again.

Don't get me wrong, head on it's a great screen, but the very sensitive viewing angles are a real shame. Most will be fine with it but if critical colour is important to you (I'm a photographer) then check the screen of the phone before you buy it if you can.

Sent fro m my S M-N910U using XDA Fr ee mobile app
[Galaxy Note 4 General] bladefrost007:
I say the viewing angles are great. I can crank down the brightness and still the screen is clear to the eyes. Not like my note 2 that i sometimes have to crank the brightness up. Maybe due to note 4's high resolution screen and the very accurate whites.
[Galaxy Note 4 General] toadsurfer:
Yeah, brightness and contrast remain good at angles, it's more the colour shift that is disappointing. Dead straight on though, it's a stunning screen which makes it all the more annoying the colours are only accurate for a narrow field of view.
[Galaxy Note 4 General] Thepunisher70:
Note 4 is monster
[Galaxy Note 4 General] horiakyys:
Hello. I intend to buy a tablet because i need Hancom office. But, In a hands-on video from mkbhd i saw this on Note 4. Is this true? In this case I will wait a little and buy this new phone.
[Galaxy Note 4 General] romreviewer:
Note 4 Rocks. Best Note Ever.
[Galaxy Note 4 General] ars_92:
are you saying that your note 4 DOESN'T have color shift? could you please check the Google webpage and tilt the phone and see whether it still stays white or it changes? My note 3 doesn't change at all even at a 90 degrees angle (auto brightness) and viewing angle is CRAZY important for me :crying:
[Galaxy Note 4 General] bladefrost007:
There is slight color shift only on the white it becomes yellowish. Not anoying at all. Still happy with my note 4.
[Galaxy Note 4 General] DelBoy:
Every Note 4 have slight color shift while changing viewing angle. It becomes little bit bluish or yellowish, depends.
[Galaxy Note 4 General] DelBoy:
And I know I probably havent answer to on all questions here, hard to find know in this many posts them.

So, please repeat question if you did not get the answer.
[Galaxy Note 4 General] alexcarterkarsus:
In gsm arena review they mentioned the immersive mode, is this present in every app now?
[Galaxy Note 4 General] getbuzzin:
What's the file size of a 30 sec 4k video? I'm trying to decide off I should go with a 128 Gb or just 64 Gb micro sd card.
[Galaxy Note 4 General] cooldoc007:
sorry if u posted this earlier.. could not find gfx benchmark.. if u could post the results?
[Galaxy Note 4 General] DelBoy:
30 second video will have around 150-180 MB.

Always go for bigger card if you can :D

Its posted couple times. Scroll back few pages, another owner posted screenshots.

But benchmark are just numbers, nothing else.
[Galaxy Note 4 General] bladefrost007:
We compared my note 4 whiteness on the iphone 5 and my buddies says my note 4 has the more true white.
[Galaxy Note 4 General] cooldoc007:
i did search.. found antutu , geekbench and browsermark.. nevermind.. jus asked.. thanks..
[Galaxy Note 4 General] MartinDimchev:
Can't wait fot 17th to come in Bulgaria... This phone is a beast.. Watched couple comparisons with iPhone 6/6+ and Note killed it.. For me the camera is the most important. How good do you find it in everyday use?
[Galaxy Note 4 General] gtg465x:
DisplayMate is in Samsung's pocket if you ask me. Also, I believe Samsung sends them devices that may not match retail units.
[Galaxy Note 4 General] WizeGuyDezignz:
Visited my local Best Buy again today to check the color shift on a white background. It definitely happens, but not at all a dealbreaker for me personally. My S5 does it a bit too. I didn't notice it on color screens really at all. YMMV.
[Galaxy Note 4 General] :
How is the build quality / look and feel cmpared to the Galaxy Alpha? I was quite impressed by the Alpha, felt like real premium quality to me.

Is there an useful driving mode (S-Voice?)?

Sorry, didn't had Samsung devices since S3. ;)
[Galaxy Note 4 General] joelteixeira:
Man, if your first assumption is right then every reviewer out there is on Samsung’s pocket. ?
[Galaxy Note 4 General] gabrielgon:
Don't have a note 4 yet, but I kept some results:

Exynos GFX benchmark:

Manhattan On	10,6

Manhattan Off	17,3

T-Rex On	26,4

T-Rex Off	37,8

These are the best results I could find, but most of them are almost as good as that. Just some people reported quite low numbers but I guess it was due to overheat or something else specific to their device. You can expect these results (or almost that) for the exynos and just a little bit better for the S805.
[Galaxy Note 4 General] toadsurfer:
Yeah, certain color screens it's harder to see, although the cynic in me thinks that is why Samsung chose the particular wallpaper it did.

Phonearena's results show a 127% deviation in rgb at 45 degrees and over 200% in grayscale, neither of which is insignificant in my view and are huge compared to all other phones. Colour images that have a lot of green or yellow in them do change quite a lot. For example trees and foliage and sunsets in movies change a lot with slight movement of the screen which is noticeable and annoying.

Personally I can just about live with it but I only go on about it as it's a shame and also people who think it will be a problem for them should def check phones before buying and try to not base checks on the default wallpaper.

As an example of how much the colour shifts, download the free 'screen adjuster' app. Max out the red channel so you have a very red screen. Then start tilting the phone. I think I may have a badly affected phone judging by what other owners here say, but by time I reach about 30 degrees, all the red has disappeared.
[Galaxy Note 4 General] bladefrost007:
Yah on my note 4 slight color shift on the white background only.
[Galaxy Note 4 General] WizeGuyDezignz:
Dealbreaker for you?
[Galaxy Note 4 General] gtg465x:
No, other reviewers think Samsung's displays are good, but they also point out flaws like the color shift in the Note 4 and realize that they aren't perfect. DisplayMate's findings never quite line up with everyone else's.
[Galaxy Note 4 General] joelteixeira:
For those with Note 4 in hands, is it possible to authorize Google Play payments using the fingerprint sensor?

The Kids Mode is available, have you tested?
[Galaxy Note 4 General] ars_92:
Is it not possible for you to exchange your unit? Since yours seems worst than others? Or it might just be that you are more sensitive than the other owners here. Damn I really feel like I might go thru what you are going thru once I get the device as im quite sensitive to color shifts...hope that isn't the case though...will be getting it on the 18th hopefully.
[Galaxy Note 4 General] bladefrost007:
No not at all. im happy with my note 4's screen. Its sharp, bright, accurate colors and vibrant. I came from a note 2.
[Galaxy Note 4 General] cooldoc007:
so the gpu is similar or worse than 420 adreno huh....!!!
[Galaxy Note 4 General] ars_92:
Does anyone know whether the bezel on the note 4 is less than the note 3?
[Galaxy Note 4 General] CLARiiON:
You should read the displaymate articles properly.
[Galaxy Note 4 General] toadsurfer:
I went back to the shop and the assistant and I looked at another note and it had the same issue so the shop wouldn't do a return as they said it's just the way the screen is made. Is OK, I can live with it, I'm just surprised the screen is worse in this respect than the s5 and s4 before it.

I am sensitive to these things and it's great that others aren't, but I am surprised others don't seem to see it much as it is quite obvious on the three note 4s I've now seen and especially as the accurate colours are vaunted by everyone whereas in fact the colours are way off from just a small change in angle depending on the image being looked at. The phone is awesome in many ways and I'm overall happy with it, just disappointed in the screen after all the hype. If I'd known, I would have stuck with the s5.
[Galaxy Note 4 General] AndroidNoob22:
Hi [MENTION=2181552]DelBoy[/MENTION], wanted to know if there are air gestures and temp sensor on the device? or Samsung has skipped on them in Note 4...
[Galaxy Note 4 General] bladefrost007:
Me too i looking for the air gesture and temp sensor on my note 4 but cant seem to find it
[Galaxy Note 4 General] squidink14:
According to the GSM Arena review they're gone:

"The IR gesture sensor of the Note 3 is gone as the Note 4 doesn't have the air gestures - obviously Samsung has decided that polishing those and making them usable isn't either feasible or worthwhile."

http://www.gsmarena.com/samsung_galaxy_note_4-review-1147p2.php
[Galaxy Note 4 General] bladefrost007:
Its okay. Theyre not the reason alone why i bought the note 4. For me those features are just add ons or gimiks. But i just hope they still included it also the temp sensor because we know the note 4 is a flagship
[Galaxy Note 4 General] markyboy81:
It's a shame the air gesture is gone as I did use the Air glance occasionally. The temperature sensor is definitely missing although this isn't a big deal for me as it was never accurate anyway.
[Galaxy Note 4 General] bladefrost007:
Does the s5 still has air gesture?
[Galaxy Note 4 General] neybos:
Is there anyone, who has compared Galaxy Note 4 and iPhone 6 Plus?
[Galaxy Note 4 General] bladefrost007:

[Galaxy Note 4 General] gabrielgon:
Can anyone make a video showing the viewing angles?? There is one on youtube but it's not possible to see any color shifts or even if it really is the note 4.
[Galaxy Note 4 General] DelBoy:
There is no air gestures.

Temperature sensor is there.
[Galaxy Note 4 General] bladefrost007:
Hi delboy, how do you know the temp sensor is there?
[Galaxy Note 4 General] geovass:
Nice. Can you take a screenshot of the temperature sensor screen please?
[Galaxy Note 4 General] DelBoy:
Sorry mate, typo.

Temperature sensor is

not

there.

Little bit drunk from last night :D
[Galaxy Note 4 General] geovass:
Ahh... No worries :)
[Galaxy Note 4 General] bladefrost007:
Oh lol! Haha [emoji38]
[Galaxy Note 4 General] DelBoy:
But you have UV sensor :D
[Galaxy Note 4 General] bladefrost007:
Haha UV and SpO2 [emoji106]
[Galaxy Note 4 General] joelteixeira:
DelBoy, could you confirm if the fingerprint sensor can be used to authorize payments on Google play store?
[Galaxy Note 4 General] DelBoy:
Most useless sensors :D

Oxygen in blood lol

They are not optimizing Chrome, Google does. And they are doing a horrible job with it, Chrome can be buttery smooth and full of leg inside 15 seconds on a single web page.

S5 LTE-A SD805 Samsung browser (top), Chrome (bottom)
[Galaxy Note 4 General] EP2008:
Actually, it's a very useful sensor, especially if you have a chronic illness, like I do. It's one thing hospitals always monitor when you're there and it's nice to see these health-related sensors being added to the devices we carry around with us.
[Galaxy Note 4 General] DelBoy:
Like this sensor can really measure true oxygen level.
[Galaxy Note 4 General] EP2008:
If anyone works in a hospital, I'd love to know how accurate this is. ?
[Galaxy Note 4 General] alexcarterkarsus:
Exactly.... which is why I think it's wrong, or even dubious for anand tech or gsm arena to present the chrome based score as the result you'd get from S5 or Note 4
[Galaxy Note 4 General] iggibar:
It actually works the same way as hospital reflectance pulse oximetry sensors. It uses a light that bounces off the persons skin and goes back to a sensor in order to give SP02 and PR readings. It's actually not that hard to make these sensors accurate due to it being a two step calculation. You have a detection, and an algorithm to give you a reading. Depending on what needs fixing, you can alter either one to give you the most accurate reading(done during manufacturing process).
[Galaxy Note 4 General] toadsurfer:
I tried but it's difficult for a video camera to show the shift. You have to just test it in person to see if it's a problem for you.
[Galaxy Note 4 General] sunny37660:
All the air gestures and stuff has been moved to accessibility area.go to accessibility and then dexterity and interactions.that's where they put it in galaxy s5
[Galaxy Note 4 General] joelteixeira:
When using private mode (to hide a file or picture for instance) this data is saved on some kind of encrypted volume or it just stop showing on default applications? Like it would be hidden or default file manager but showing on es file Explorer...
[Galaxy Note 4 General] EP2008:
Yes, but do we actually know how accurate the Note 4's sensor is vs. a calibrated hospital device?
[Galaxy Note 4 General] joelteixeira:
It's a bonus, just like the heart rate monitor you can't compete with professional and dedicated devices.
[Galaxy Note 4 General] EP2008:
Sure, but I'm assuming that it's accurate enough to be useful. I plan on using both the HR and o2 sensors on my device. :good:
[Galaxy Note 4 General] OnlinePredator:
It's AMOLED, so there isn't any?
[Galaxy Note 4 General] gabrielgon:
The color shift is a fact as it was stated by many users.
[Galaxy Note 4 General] OnlinePredator:
Then why are your asking if you already have the facts? Perhaps this is due to the curved screen?

Okay saw the video, had to focus to see the difference. Not sure if it's legit. Again shouldn't be a thing for amoled at all which is really weird.
[Galaxy Note 4 General] bladefrost007:
Im comparing my note 2 and note 4's viewing angle. When viewed at extreme angles close to 90 degrees my note 4's display is much clearer and sharper. Color shift i notice very little to none. Maybe it just because when you view it at an angle the brightness you see on the screen is reduced and gives the effect of color shifting.
[Galaxy Note 4 General] toadsurfer:
I'm jealous of your viewing angles! I'm getting really annoyed with my screen. I'm also getting obsessed; I spend my evenings tilting my screen backwards and forwards, tutting, with my girlfriend looking on in despair.

Brightness and contrast actually remain good on mine at an angle but the blue tint creeps in very early with tilting and increases the further you go. If you do the test code (*#0*#) and select the green screen, and then tilt the phone backwards and forwards quickly, mine goes clearly from a yellowy green to dark green with little tilting. The red test screen goes sharply from red to orange. It's not so much the shift at large angles I care about, more the subtle hue change at very small changes in screen angle that gives subtle but noticeable changes to images.
[Galaxy Note 4 General] bladefrost007:
I dont know but i havent noticed color shifting on mine until i read comments but it is so minimal to none. Maybe im just getting paranoid or just imagining. The note 4 has the best display off all smartphones
[Galaxy Note 4 General] toadsurfer:
Yeah, I kinda wish I'd never noticed it, but on my phone at least the shift is not minimal.
[Galaxy Note 4 General] gabrielgon:
I'm asking because I wanted to see it and have my on conclusions about it. No note 4s in Brazil yet for me to see it in person.

---------- Post added at 04:51 AM ---------- Previous post was at 04:45 AM ----------

Didn't look for new videos this weekend but there's one that actually shows it pretty well. Here it is: https://www.youtube.com/watch?v=aVrm73sAnUs

Looks pretty bad. Can't image how they released an 800 dollar phone with that. "Look! Our screen looks amzing! It' got 45678987654563454323789876 pixels!" aaaaaaaaaaaaaand the color shifts like a 100 dollar phone. Congratulations Samsung guys, your are a bunch of idiots :good:
[Galaxy Note 4 General] pafc66:
I just received mine today its the exynos version. noticed its not the bright in direct sunlight and when under alot of light and with auto brightness on the whole display kind of goes into over exposure and the colours appear to wash out? i might have to send mine back. bought it from unique mobiles here online in australia. This overexposure thing doesnt seem to happen with its set to manual full brightness. Would this be a hardware or software fault? anyone else getting this?
[Galaxy Note 4 General] gabrielgon:
Have no idea how most of the reviews are not stating this. The one which say something, is just a commentary. To me, it looks ridiculous, sorry. Haven't seen the phone in person so I still may change my mind.
[Galaxy Note 4 General] bladefrost007:
Mine does it too when set to auto brigtness and at outdoors the screen would brighten over 100% and colors looks washed out
[Galaxy Note 4 General] pafc66:
Must be a common problem. . No good. Where did you buy yours from?
[Galaxy Note 4 General] bladefrost007:
Its a hongkong/china version of note 4 sm-910u. I bought here in the philippines at a local grey market
[Galaxy Note 4 General] ShadowFlare:
It's not a fault, that's how it works under sun light or very bright light.

When you manually set brightness to max, it is literally maxed at that setting. BUT, if you set brightness to AUTO, you will unlock the brightness to go BEYOND the max settings, sacrificing colour accuracy in order to achieve that next level in brightness.

My Galaxy S5 Mini does it, and here's a review below that mentioned it. So no, it;s not broken, it's just trying to reach up to 750cd/m2 level of brightness (according to Displaymate's measurement).

http://www.androidcentral.com/samsung-galaxy-s5-mini-review
[Galaxy Note 4 General] Magnesus:
It might be on purpose? I had an LCD screen that allowed setting brightness like that on higher settings - it's useless and stupid but maybe Samsung thought it might help in very bright light?
[Galaxy Note 4 General] pafc66:
Hmm that makes me breathe a little easier then I guess but it seems like a odd feature I can tell you my Samsung s5 definitely didn't feature this. Comparing it to my old s5 it definitely does not get as bright . Would this be because of the 2k display?
[Galaxy Note 4 General] ShadowFlare:
The review mentioned that the S5 has this feature too but the colours did not go as bad as the mini. And if the Note 4's colours are washed out under sun light, maybe due to the new 2K display. It is after all the first 5.7" AMOLED 1440p display. So probably not yet perfected to retain colour accuracy under sun light.

Or maybe that you have Adapt Display mode on, and when it kicks to Super Brightness, it switches to Basic and made colours see wash out, since your eyes are used to the punchy Adapt Display colours. Just a thought, I don't have a Note 4.
[Galaxy Note 4 General] pafc66:
Your right I just tried my Samsung tab s 10.5 outside in the aussie sun and it went all weird colours on auto brightness as well .. I guess the s5 just felt brighter due to lower res
[Galaxy Note 4 General] Lodix:
In normal conditions the note 4 display will be a bit dimmer compared to S5 but it will be because of Samsung keeping battery life. But it will be more brighter than the Note 3 anyway and in auto brightness it is supposed to be brighter than the S5. The changes in colors is made in purposed to make it more easy to see under the sun.
