Hello,
I'm a heavy user of Glide and I get really annoyed by how the Samsung Note 4 front-facing camera performs. It seems that Samsung implemented low light compensation which makes any head or hands movement look ghostly. I'm deaf so use sign language over Glide video to my friends and my hands blur easily when using front camera.
Is there a way to turn off the low light compensation or does anyone know the proper channels for me to go through with Samsung to ask them to, at least, add this as an option.
Thanks,
Jared
i'm quite disappointed with the front facing camera as well. on paper a 3.7 mpx front facing camera with "wide angle lens" should appeal
to most people, myself included. i've found that the front facing camera has lots of ghosting, choppy and partly blurry movement.
this is only confined to the normal selfie mode on my phone though. i have tested out the wide angle selfe mode, and that one seem to
work fine, with smooth and decent motion and movement. most people haven't complained about this, but i'm definitely bothered by it.

So, my problem is that my camera does not seem to focus an Objekt, even when I "touch " it in the camera app. It is still a bit blurry when I view the taken shot. When I look at my friends Nexus 4, colors are much better and everything is sharp. Is it possible that I have a broken camera? The settings are exactly the same...
It may be helpful to post some example shots.
1st thing to look for is to make sure that the glass covering the lens is clean. And shoot in good lighting.
Known problem, please star the issue http://code.google.com/p/android/issues/detail?id=43153&thanks=43153&ts=1359017856
AW: Bad camera focus
And the washed out colors? Max it be the fault of rev10 devices? A friend of mine said something like that
//edit
Here's a sample. If you zomm in you will see the Blurry borders. They are really annoying because when I look at the pic on a PC, I am able to notice it. Maybe it's the cameras fault or Googles fault for bad drivers and software.

It seems to me like the hardware is perfectly capable of the focal lengths to get clear focus, it's just the autofocus implementation that's broken. Is autofocus a driver level implementation? If so, would it be feasible to try and create a custom driver to at least allow for true manual focus?
There are several things that can be going on here. 1.) it ain't a great lens, so not all areas of the picture are going to be razor sharp. I see a good degree of softness in the corners.
2.) I have noticed the camera's default behavior is to use lower ISO, and longer shutter speeds in less than ideal light, making camera movement a major factor in blurry photos. If you're gonna test under less than ideal light, rig up some kind of tripod.
3.) Auto-focus algorithms decide focus based on maximum contrast. If the area of your focus reticle is over an area that has poor contrast, focus will be compromised. Low light also lowers contrast.
4.) Depth of field. It is limited with this lens. Make sure areas you are checking for focus are on/near the same plane with shots that have reasonable distance separating foreground/background objects. They all can't be in focus.
With all that said, reasonable photography skills can get pretty reasonable results from this camera, as is exhibited in the photos posted in the photo thread of the "general" forum.
It does focus, but has a small delay tho..
actually the focus on N4 is slow a little bit ..
Is there any new piece of information about the bad camera focus?
anyone else have a pink haze when capturing white objects
Is it possible to capture a photo in broad daylight and have it look like this? The noise is HORRIBLE! (skin correction is turned off). I dont even dare take selfie shots. The results are ALWAYS awful not matter the lighting conditions.
This is during daylight:

No one? Everyone's Note 4 takes so bad front camera pictures? Oo
bump
This is unfortunately typical of the Note 4's front camera. The module's just not quite up to snuff - it's got a tiny sensor without OIS. Sure, the optics get a bit more light in, but at the cost of stretching things near the edges.
Skin correction "helps" things a bit I guess, by blurring the skin surface so you don't see image artifacts, but it makes other things in the frame blurry.
This is very weird. The Note 3 I had before had a better front camera than the Note 4!
For some reason the exposure on the front camera is really low. When switching back and forth from selfie mode and video mode there is a huge drop in exposure, compared to the front camera where there isn't any difference at all. Looking at all the video tests for the front camera on youtube, they all look fine in comparison. I can't tell if this is a hardware defect or if the front video camera on the axon 7 isn't that great. Anybody else have this issue?

Hi, I have the same problem at low light but it's fine at good light condition. It seems that the back camera automatically adjusts the exposure at low light, but the font camera does a bad job. However, you can manually adjust the exposure thorough the vertical slider on the right. The algorithm of Axon 7's camera sucks!
Hi all - it sounds like the front (selfie) camera does not take the best pics.
One of the uses I wanted for the G6 is to use the back camera (the wide angle one) to take selfies instead.
I won't be able to see the screen, but with the wide angle lens, I don't really need to do much framing I'm guessing.
The only thing that I'm concerned about is the lack of auto focus and if the wide angle camera can focus on subjects about 1 metre away from them.
Does anyone have a G6 who could comment / or post a sample pic of this? This is pretty much the dealbreaker for me to get this phone.
Cheers!
I'm interested in the same question! Would be great if anyone could comment on this, hence bumping this thread.
Yes. Front facing camera is not as good as it should be. Specially in low light situation...
This, and lack of LED notification light are the biggest flaw to me
Back cameras takes good selfies though. I don't have any problem with framing or autofocus. Does a good job with defocusing background and shaking effect is at minimum thanks to new image stabilizing system.
Hope this help you
Cheers
Someone here at xda calculated that all things between 35cm and infinity are in Focus for the wide angle camera.
I also made some tests and I think that he is not totaly wrong with his 35cm.
So taking selfies should be ok.
The highlighted thing about g5 plus was also the reason for bad camera. The 1.7 aperture and wide angle camera are the cause here. Though it is good for shots within a certain distance like 10-15 feet. But any further the pictures loose sharpness and gets noisy due to which moto decided to use high denoising due to which the photos look soft. My father's redmi 4 clicks better distance pictures than this. It has 2.0 aperture and little less wide angle lens.
Don't forget that G5 Plus have the same camera sensor as HTC U11 or Asus Zenfone 4 (which takes good pictures on stock software).
Worse photo quality is caused by software (Motorola/Lenovo screw it up).
Did you tried any mods/apps? You can find a lot of these, but I suggest you to try Google camera app port.

I use bacon camera on stock Android without root.
I disabled noise reduction and use hdr with manual mode and stable hands to get though grainy but nice pictures. Though the app is not perfect but it works
When I first got the G5+ I thought the camera was too dark... While a lower aperture may help in low light shots it does cause a bit of trouble for highly illuminated scenes.
HDR does compensate but it's nothing like HDR+ from Google.
Plus, terrible sharpen and overdone Noise Reduction excessive Color NR.
I felt quite dissapointed comparing it to my old Titan (G2)
Anyone tried to mod the camera to enable debug mode? You can disable noise reduction from there

Coming from an old school enthusiast of photography background - you're aperture on your lens (in this case f1.7) isn't going to cause noise - that's a function of the sensor. A lot changed when we went from film to digital sensors, but the impact of the f number of the lens did not.
You might be on to something with the with loss of sharpness though. Typically a fixed focal length lens is at it's sharpest at it's only setting... but they very well could have forked this up.
Given that the camera does pretty adequately with other camera software or other hacks - I don't think it's a hardware issue or lens issue. It could be a cut rate sensor...
It could also just be that whomever chose the default settings for this camera did a bad job

What about shadows in bright scenes such as outdoor scenery?
I mean, wouldn't lens aperture like f2.2 preserve more of these details?
That's a function of the film/sensor.
Your f number controls light and the depth of field (area that's in focus) - a smaller f number is more desirable because it allows more light to the film/sensor.
The only thing different here than fine that I can see is the size/diameter of the lens related to the f number. A larger f number, like f 8 or f16 increases the depth of field and sharpness, but at the cost of light hitting the film/sensor. That results in a longer exposure time.
A wide open f stop means more light and shorter exposure times.
One thing we gained with sensors over film is a wider range between highlights and shadows... You could get more shadows and more highlights. Film could get only so much of that before shadows went black and highlights blew out to white. But you still have a limited range. You can't get it all. In order to keep the highlights from going completely white you have to trade off some of the shadow range.
It's early and I'm probably explaining this horribly. Your spectrum between black and white or shadows and highlights is very long. But your camera sensors capability can only encompass a range of that spectrum. If the spectrum were a line of shades of grey from black to white that was, say, 10 units long, the range you could get in one image might be six units long. You've gotta give up somcombo of four units either at the black end of the spectrum or the light side.
If the cameras loaing details in the shadows that's because it's opting to the highlight/light end of the range.
So lens doesn't play a huge role in what chunk of the spectrum the film/sensor can encompass. But does play a role in how quickly the sensor can collect that info. Higher f number = smaller amounts of light on the sensor = longer exposure times.
My guess would be that the sensor or software is biased toward highlights because it results in faster exposures making life easier for snap shots and selfies.
