It may be due to the fact that I still had the protective film on the camera?
[Galaxy S6 General] nlab:
Looks like oily lens. Try to clean and re-shot.

You should also look if there is a protective film on a camera.

If this doesn't help, be sure to ask for a replacement.
[Galaxy S6 General] gianni500:
yes, there was the protective film. Now I removed, tonight I try to photograph a hot stove in the dark
[Galaxy S6 General] TheWarKeeper:
I believe its very unlikely to be the plastic film at fault but let us know anyways.

Isocell 60fps video problem

Recently I bought Samsung Galaxy S6 (in Latvia, Europe). I got Samsung Isocell (SLSI_S5K2P2_FIMC_IS) camera sensor. When I film using 60fps mode at low light conditions, i got vibrating blue violet video noise on every black place. My friend got Sony sensor in his device, and there is not such a problem.

Can anybody check this 60fps filming mode in low light on your Galaxy S6 series phone, especially if you got Samsung Isocell camera sensor?

I got video example, but cause I'm new user here, forum did not allow me to share it with you :( To illustrate it, I can only give youtube video link watch code: mu036C41By0 . There is also original file shared in the youtube's video description.
[Galaxy S6 General] nlab:
The same blue noise for my s6, isocell sensor. Is it fixed in 6.0.1?
[Galaxy S6 General] RobertsLej:
In my country Samsung official support is very stupid. They didn't even check the problem, they simply changed camera sensors, then they change even motherboard (for warranty), but as the problem stayed the same, they said that there is nothing more they can do. I'm not satisfied with such answer, so I want to know is that's sensor problem, and if so, then i'll be asking to change it to sony sensor. Cause this problem is huge, and there is none info in web about it, cause 60fps is rarely used, and all tests done with first phones, which got Sony sensors.

It seems that Latvia's Samsung support does even know, that there are different camera sensors for S6.
[Galaxy S6 General] Samed92:
Same here on my ISOCELL S6 edge+ . I had the Sony Sensor before and it was much better in low light in terms of noise and details. ISOCELL sucks... I will change it in a few weeks. 740€ for a bad camera...

---------- Post added at 05:00 PM ---------- Previous post was at 04:59 PM ----------

This is normal on the Sony AND the Isocell sensor. Its because of the lens. Somehow I didn't got this Problem on my galaxy note edge (sony sensor) before.
[Galaxy S6 General] gianni500:
ok, thank you, actually searching the web I saw other photos with the same effect caused by the lenses
[Galaxy S6 General] gylbert:
I have the same blueish video for 60fps,on low light. S6 , isocell sensor. It's annoying because I like very much this mode during the day, but at night I need to remember to change it back to default.
[Galaxy S6 General] Duzzy5:
i have same effect with mine. i guess this is normal :D maybe not, because galaxy s6 have some faults by default.. oh yeah got isocell sensor, and had buzz and vibrate from it ounce (ois mechanism i guess - that is common too)
[Galaxy S6 General] jocaboss:
The Sony ones has a very blueish effect on the sky and don't like this at all.
[Galaxy S6 General] wilmark23:
same here 60fps video recording have blue noise on dark edge isocell sensor hopefully it can be fix in upcoming MM update :(
[Galaxy S6 General] TheWarKeeper:
You mean because of that 1 bad photo taken in HDR mode at the time when the sun was fading into night in sammobile?

Ive got a Sony sensor and that doesnt happen to me at all be it daylight or lowlight, all colours are way more accurate on my new galaxy s6 sony sensor than my old galaxy s6 isocell sensor
[Galaxy S6 General] jocaboss:
Yes but the blueish effect is in the auto mode. The HDR one is a bit better. For me based on the sammobile.com pictures i don't like the sony at all.
[Galaxy S6 General] TheEndHK:
Same here. My ISOCell color way better than my Sony Sensor and so the auto exposure. But the ISOCell real got blue effect during at extreme low-light video recording but it only happens in completely dark environment to me and never being a real problem bcoz I never shoot at such extreme condition even without the blue effect, the video quality is unusable.
[Galaxy S6 General] jocaboss:
I has noticed the blue effect in video. But as you said, i don't make any video in that conditions without flash.

So far happy with my s6 isocell sensor,not much difference to sony ?
[Galaxy S6 General] jocaboss:
Very happy indeed. Here is an example.
[Galaxy S6 General] supera3:
amazing pic friend
[Galaxy S6 General] EQ2000:
And looking att comparision with different ISO the Sony sensor walks all over the ISOCELL. Beyond ISO 200 one can start to see difference in IQ and the higher the ISO the more stark the differences. ISOCELL just is sub-par. Not even night-mode with longer exposure time and multi-frame noise reduction saves it as you need to have the camera absolutely still for seconds just like with the S5 else you get a mess.
[Galaxy S6 General] TheWarKeeper:
Yeah its funny people now are actually trying to make imaginative faults with the sony sensor just because they own an isocell... theres no such thing as blue issue with the sony sensor and color wise it only looses to xperia z5 sensor color accuracy by a very small margin which says alot since xperia z5 has the best color output found in any phone camera sensor to date, it even trumps the over saturated colors of the nokia lumia 950xl
[Galaxy S6 General] eum1r:
Its very funny,i mean very very funny that imx sensor user think that they treat their sensor as perfect and treat the isocell as worst,hahaha,i dont have to tell about my observation to imx or isocell,as a phone photographer im happy with my imperfect isocell sensor ???

---------- Post added at 04:09 AM ---------- Previous post was at 03:58 AM ----------

Nice shot man,i dont know these people are mad at isocell,they make me laugh when they are talking bad about our isocell,nyahhaha
[Galaxy S6 General] EQ2000:
It's not as good as the IMX240 camera module but it doesn't mean it is bad, just not as good and not as advertised by Samsung and what is used for pretty much every single review unit Samsung sends out. That is what the discussion here is revolving around and the fraud Samsung has been pulling upon its users. Defending that is quite ingenious becouse it is you the user that will suffer. And day/bright photos wont say that much becouse a "potato" could also take damn good photos when the shutter speed can go beyond 1/250. And we are all pro photographers on the internet, heroes, firefighters and own atleast one Bugatti.. :laugh:

See, that photo has great composition and view but quality is horrible (view it on a monitor/TV screen). Just look att the artifacts, color blotches, noise, smudging all over the scene and yet it is downscaled to 1328x747 resolution. And the scene aint so dark either. It wouldn't surprise me if shutter speed was 1/64 or higher and ISO below 400. But ofcourse if you are happy then.. But fact is it has damn low IQ, "potato" quality. :cool:
[Galaxy S6 General] naokilla:
Had an imx with my edge on an early unit, swapped it with a standard s6(glare on edges was annoying), and can notice a vry slight difference with zoomed quality which is better with the sony sensor, although it does have the blueish hue with some shots. However these differences are so minute and after using the cams on several other top handsets, motorolas, lg's, nexus and even my iphone 6s, ive got to say the handset im using now with the isocell still blows them all out of the water. There really is nothing in it, and once you know what your doing with pro cam settings etc the pictures are beautiful on either. Neither one is better than the other!
[Galaxy S6 General] eum1r:
...

I understand you man,i think the others have slightly defect isocell,including me,but the other isocell sensor doesnt have issue,and so on same sensors both have defective sensor

I agree with you

Who can send me untouched pictures of low light both sony and isocell? Full reso pls.. thanks
[Galaxy S6 General] jonymimoso:
Mine ISOCELL takes excellent pictures, I do have an good unit.

Thanks man,i see there that sony is slightly better than isocell,maybe his isocell got some slightly defect sensor,i say so because other isocell sensor user i saw has a good quality,equally or maybe better than sony in other low light scenes

Check mine guys,all comments are welcome s6 g920L isocell full auto
[Galaxy S6 General] EQ2000:
It does ressemble the other comparision in as the ISOCELL having more agressive 'big block' noise reduction in low contrast areas (shadows/dark areas) at ISO 320, 400. This due to more noise as you can see quite a lot of noise and slight smudging of the overall image aswell as prefering a yellow color tone when handling tungsten lightsources. This opposed to the IMX240 which goes for a less saturated but more realistic image by reducing vibrancy value and/or tweaking blue color channel.

As for the San Miguel bottle and bike, is it in night mode? Becouse in night mode you dont get ISO nor shutter speed value on the S5 (and I reckon it is similar for S6) due to it taking a multi-frame photo with slower shutter speed to lit up scene and remove noise based on differences in luminance between both captures (might be 3 photos but atleast 2). You just need to hold the phone absolutely still for some seconds else it creates a mess.

[Galaxy S6 General] Pierre118:
I have read the whole thread. I have the choice between a Isocell and a IMX240 S6 Edge+. I know most people would advice the IMX240, but still i don't know which one to choose. The quality of Low light pictures is very important for me.
[Galaxy S6 General] TheWarKeeper:
isocell quality looses to sony imx 240 in every light condition, isocell has more noise, less color accuracy and more smudges.

PS: unlesss youre buying a second handed or voided seal unit, you do not have the choice to choose isocell or sony, they are product number independant and impossible to be distinguished without opening its case and voiding the case seal.
[Galaxy S6 General] Samed92:
Could someone with an S6 edge plus and a Sony Sensor post an unedited .dng RAW image? I have got so much noise when I capture RAW images with my ISOCELL Sensor, even on ISO 50. I know it's normal, because there is no post processing and I have to reduce the noise by myself but there is too much noise. On my Galaxy S6 edge with Sony sensor before I didn't have so much noise.

And guys, Sony sensor has got much more details and less noise in low light. Also the Video Quality is much better. I got two ISOCELL and two Sony Sensors since now. The first ISOCELL had a really bad quality ( I had the imx240 on my Galaxy Note edge before and was really disappointed). Then I got the Sony sensor on my old S6 edge and it was really a huge difference to the ISOCELL Sensor.

Now I got the S6 edge plus and I can say, that it is better than my first ISOCELL Sensor but still not as good as IMX240.

I would be happy if someone could post unedited raw images here.
[Galaxy S6 General] Pierre118:
Thanks for the fast response. I have the choice between 1 new one that has the Isocell sensor(they checked for me) and a used second hand that has a IMX240.

I have tried them for a short while. The Isocell images, taken in a sunshine lit room, looked brighter than the IMX240 pictures. What are the best circumstances to test the differences between the two sensors?
[Galaxy S6 General] jonymimoso:
Mine ISOCELL is pretty damm good. If you know how take shots it will be as good as another. The advantage of the ISOCELL technology is that captures more light than similar sensor, is not much but it will possible to taken shots as bright using lower ISO. I do not tried take on raw, I am wating for the official Android mm for that
[Galaxy S6 General] Pierre118:
Does the ISOCELL captures more light because of the hardware of because of the software?
[Galaxy S6 General] jonymimoso:
On theory, the ISOCELL sensor uses isolation in each color pixel. Because of that the sensor have an decreased light loss. Of course that this is on theory.. If you compare the Sony and Samsung sensor you will notice that the samsung sensor use lower ISO at the same shutter speed.
[Galaxy S6 General] Pierre118:
So, in theory : when you should use the same ISO, shutter speed and all other preferences, the results will be the same under all circumstances?
[Galaxy S6 General] jonymimoso:
On the low light scenes the lower ISO will produce less digital noise. In mine experience with the S6 ISOCELL, the quality is really good. In auto mode I noticed that sometimes takes one picture with low ISO and other with higher ISO but that is an fail from the software and quite rare to happen. On daily use I do like the quality. Mine girlfriend have an S5 that have ISOCELL sensor and on the same ISO mine shots is much better, maybe I have an good ISOCELL sensor unit.
[Galaxy S6 General] EQ2000:
Looking at comparision at Flickr they both use same shutter speed and ISO and Sony sensor performs better. If anything the ISOCELL looks like it is brightening the image by manipulating exposure curves while trying to recover detail in dark areas resulting in an image that looks smudged as it doesn't do it that well. Kinda gets the 'fake high ISO' look.

Intersting though that S5 with ISOCELL can do ISO 2000 although it suffers greatly regarding IQ unless night mode is used and on the S5 it goes for high ISO even in medium/low light indoor scene.
[Galaxy S6 General] jonymimoso:
Can do you share that Flickr comparison?
[Galaxy S6 General] EQ2000:
Watch them in Flickr to see them in in larger size or download for fullsize.

http://xdaforums.com/showpost.php?p=64438503&postcount=873
[Galaxy S6 General] Pierre118:
The manipulating of the exposure curves, is that something that is in the firmware of the ISOCELL sensor hardware?
[Galaxy S6 General] EQ2000:
Firmware/camera framework software. But it should be configurable you would just probably end up with a darker image than the Sony IMX240 sensor and to make it look similar the ISOCELL would need to ramp up the ISO and suffer even more regarding image quality so I guess this was their solution to keep both sensors outputting similar photos at the same ISO and shutter speed.
[Galaxy S6 General] jonymimoso:
One thing that I noticed is that using the official camera app all photos came better.. Since that guy have exposures of 1 sec I must believe that used an 3.rd party app.. There is various comparisons that shows ISOCELL sensor almost as good as Sony.
[Galaxy S6 General] EQ2000:
Though the detailed exif information says he used the stock Samsung camera app "Software - G920FXXU3COI9" / "Software - G925FXXU3COI9". 1s shutter speed is not for the comparision shots he put upp as none of them has such slow shutter speed. Otherwise for his other photos it might be 3rd party or Samsungs multi-frame, slow shutter speed "Night Mode".
[Galaxy S6 General] Pierre118:
So, you recommend the S6 edge+ with the IMX240 sensor to buy?
[Galaxy S6 General] EQ2000:
Yes it will give you best photos regarding detail, post-processing configuration and colors compared to ISOCELL edition.
[Galaxy S6 General] forumber2:

[Galaxy S6 General] TheWarKeeper:
The isocell sensor is not a very bad sensor, nobody can say that, its quality is close to the imx_240 sensor but its still worse than the imx_240 sensor in several areas.

The "capture more light is bullcrap" marketing tactic by samsung, it never really proved to be the case in real life, infact, it introduced more noise and less color accuracy because of that system, as they had to shrink the pixels even thinner to accomodate for such light blockers....

In the end they ended up with a good sensor instead of a revolutionary sensor, and sony imx_240 beats it in every test.

As for the reason why the images look brighter in the isocell sensor at night even though its blurry as heck is because the drivers of the camera forces the brightness of the image up, trying to give you the hidden details that normaly is hard to see on a low brightness image, if you photoshop your images in sony isocell and brighten them up the same as the isocell you get same detail but with less blurr and less noise.
[Galaxy S6 General] jocaboss:
Nice picture. I'm really wanting the marshmallow for tweaking the shutter speed.
[Galaxy S6 General] Pierre118:
What do you all think of this comparison : http://www.sammobile.com/2015/05/05...-camera-sensors-on-the-galaxy-s6-and-s6-edge/

The low light pictures of the IMX240 look very purple to me. What do you think?
[Galaxy S6 General] eric150:
The ISOCELL appears to be equal or better in all the examples
[Galaxy S6 General] Pierre118:
I don't think so. The low light ISOCELL pictures have a lot of more noise than the IMX240. Under 'normal' conditions you would not notice, but on my iMac 5k it is clearly to see.
[Galaxy S6 General] jocaboss:
But they have very purplish effect.
[Galaxy S6 General] Pierre118:
That's true, the low light looks very purple on the IMX240.

I have examined that the file size of a IMX240 picture is about 10% higher than the ISOCELL version. I just took 2 exactly the same photos. With IMX240 it is 4,9MiB and the ISOCELL one is 4,5MiB

Update : the exposure time of the ISOCELL photo was 1/17 and the IMX240 photo 1/14. Both pictures taken in auto mode with HDR auto. I am a real amateur so can anybody can explain this exposure time to me? What is the difference?
[Galaxy S6 General] TheWarKeeper:
Lol imx 240 has no purple issue. That only happened in that biased review and it isnt even very low light... i had both and i still own imx 240 and i never experienced that strange error
[Galaxy S6 General] jocaboss:
The difference is the sony sensor in that photo absorbs light during 1/14s before the shot and ISOCELL 1/17s
[Galaxy S6 General] jonymimoso:
Mine ISOCELL do not have that purple color..
[Galaxy S6 General] Pierre118:
Why lol??? Maybe there are differences between some IMX240 batches. That can be possible. I try to be objective and share information,
[Galaxy S6 General] jonymimoso:
I do believe that as well.. There is so many people telling that ISOCELL is much bad. Mine is really good
[Galaxy S6 General] jocaboss:
The purple effect is actually on sony pictures in sammobile.com comparison. I like my ISOCELL a lot too.
[Galaxy S6 General] EQ2000:
Post some non-macro low light shots where ISO is 400, 800 and 1000 and scene depth is 10m+ and atleast 30% is covered in shadows.

---------- Post added at 12:18 AM ---------- Previous post was at 12:11 AM ----------

If they use same jpeg compression which they should then the IMX240 shot contains more information which means there is more detail (contrasts, colors and texture detail). That means less blur to. Shutter speed is how long time light photons are absorbed, how long time the shutter is open. 1/17 would theoretically mean it can take 17 photos in a second. The longer the shutter is open, the more important it is to hold the camera still and have minimal amount of object movement in scene that is going to be captured to prevent motionblur.
[Galaxy S6 General] jonymimoso:
Well saying that 1/17 is equivalent to take 17 shots in a second is not correct. This is an shutter speed and indicates that each photon received light for 1/17 of second or ~3.5 milliseconds. Longer exposures can lead to shaky pictures but is not only that, it can raise the temperature and produce pictures with burned pixels, even at low ISO.. I can take the pictures and sent do you what requested
[Galaxy S6 General] Pierre118:
So, when i understand you well.......the IMX240(1/14) shutter was opened a little bit longer than the ISOCELL(1/17)?
[Galaxy S6 General] TheWarKeeper:
See the russian isocell vs imx 240 side by side comparison for an actually serious testing with All lighting conditions from very high to high to normal to low and to very low light. It shows 0 puprle shots for imx sensor and shows considerable quality improvement over isocell in pretty much all of the shots 100% zoom side by side
[Galaxy S6 General] EQ2000:
I said theoretically just to give something to compare against in terms of understanding. 1/17 is 58,8ms. Yeah sensors have their optimal working temperature. Not to warm and not to cold and as you say slower shutter speeds as in going beyond a second and especially together with high ISO will introduce heat related noise. The worst is though moderately slow shutter speed and very high ISO considering high ISO requires more current to the sensor pixels and the sensors are very small in mobile cameras. Do so. :)

---------- Post added at 12:55 AM ---------- Previous post was at 12:52 AM ----------

Yes, 71,5ms vs 58.8ms. But on the Flickr test both ISOCELL and IMX240 had same ISO and shutter speed for each comparision set.
[Galaxy S6 General] Pierre118:
Still the Sammobile test results in some purple pictures by the imx240. And they were taken at the same lightning conditions and same settings, just lke the Flickr comparison. Strange but true.
[Galaxy S6 General] theronlas:
Or it means that there is more noise, noise compresses very badly and will cause large files.
[Galaxy S6 General] EQ2000:
Fine grain noise with high contrast edges. There is barely any such to see in the photos so we can exclude "film grain" type of noise. All you see is smoothed out noise (looks blotchy) which means blur which means less detail thus smaller filesize for ISOCELL. It's evident in the comparisions.
[Galaxy S6 General] molanjami:
I personally like the Samsung sensor. the colours of the water pictures are more natural for me than the Sony
[Galaxy S6 General] TheWarKeeper:
I see.... have you even examined the exif data of the said "same settings"? even the isos are different, so so much for "same settings"

Theres no purple tint on Sony IMX 240, i have it lots of other people have it and know that information is just false.
