Hi,
I'm unrooted, stock V10h.
After noticing that the stock camera photos are very compressed (8MP photos never go above 3MBs) with no option to change that, I installed Camera Zoom FX. All seemed good, but then on a sunny day after taking *lots* of photos, noticed I couldn't view some of them on the phone, although thumbnails were there. Came home, transferred to PC, opened and noticed that the ones the phone couldn't display were corrupted. All of them, had a gray bar at the bottom, some more, some less. Obviously the compressed jpg stream was broken after some point.
Thought it was Camera Zoom FX's problem, because this never happened with the native camera app. Uninstalled.
Still wanting better quality, installed Camera ICS. Great too. But same problem too (on some photos again).
Went on to install Camera MX. Same.
Finally narrowed it down to this:
if resulting photo is > 5MB (more precise: if > 5130 KB) then it's corrupted
(and that's why the native camera doesn't have this problem: there's no way to choose better JPG quality for it to make 5MB photos).
I thought: memory speed problem. But then again, the photos were saved in the phone internal memory. Internal memory is not supposed to have speed problems. Anyway, I tried saving to Class 6 and Class 10 SD card, and the results were the same.
Anyone know about this?
Also, please report if your >5MB pictures are fine (in case you shoot at that quality), and what app you use to take them.
Note: the problem seems to be there with jpg photos in general, irrespective of device. Here's a link of someone experiencing the same photo corruption on a normal camera (Casio EX-F1). The problem with my photos is exactly as in the photo he posts a bit later in the thread.
Ok noone seems to know anything about it.
Could someone at least please report if you can get photos equal to or above 5Mb in size, whatever camera app you are using and whether the photos are ok?
(to get that quality, you must select 8 megapixels and then the highest quality in some other setting. For example camera zoom fx and camera mx have a percentage slider (set it to 100), while camera ICS names the quality (select ultra). Also a steady shot and lots of light is needed for the pictures to go up to 5Mb even in these settings.)

Just tested with Camera ICS.... Same issue as you. Photo was 5,266,434.00 bytes.
Using V10h Euro Open.
i had the same issue on deodexed ICS i had a week after purchase, and after i installed this mod:
http://forum.xda-developers.com/showthread.php?t=1855818
i tought the mod broke my camera, but i guess it was this bug/limit.
Thank you both for reporting. At least now we know it's an (LG implementation?) android bug.
Really annoying to me, as I would like to use the camera's full potential. Hope this gets fixed in the upcoming JB for 4X.
(although in order for something to be fixed, LG would have to know. And this problem surely hasn't received attention since it seems I am the first one to bring it up).
It would be interesting to see what would happen if someone with v20a tested this.
Yes indeed.
On another note, I also checked GeoCam and sometimes it gives an error (not enough memory or something). The photos that it saves with no problem are maximum < 5 Mb, so I assume it is the same problem. But this app demonstrates that there is a way for the programmer to know that during saving the photo something did not go as expected.
Where exactly the bug lies, is another matter.

i might try the mod in official 4.1 when it's out and someone releases a deodexed version, just to check if it works on JB.
this is quite a strange problem we have on our hands, i did some search on google, and haven't found many similar problems.

I too am anxiously waiting for the official 4.1 and was hoping that it would not have this problem.. just wishful thinking..
i already know it a long time ago, and i asked about this at the camera MOD thread by ksekhar http://forum.xda-developers.com/showthread.php?t=1855818. but no one seems to bother

Hello ksekhar. I found a problem in the LG firmware, it appears in your mod too.
In third-party programs (ICS camera+) and in your camera mod of the compression quality jpeg minimum, maximum file size.
In some conditions, such as the leaves in the sun, the size of the file begins to exceed 5 megabytes. Then the problems start.
This file is written to the error (broken jpeg file). I've been thinking why this is so and finally got it.
In your version, you just increase the compression quality to any situation the file size is not more than 4-5 MB.
Also, if you is not difficult, please do me a version (as we did earlier) which fixes only compression jpeg,
but the quality of compression should be a cross between the standard version and your version.
Or tell me how I myself can change the quality of compression.
For example (like photoshop - compression level from 0 to 12)
Original LG camera - compression 9
Your mod - compression 12
The required - compression 10.
Link to example of broken jpeg file: http://narod.ru/disk/61445464001.4b4c982386ce7c47b2214e33a90a25aa/bug_IMG_20120923_124127.jpg.html

i have this problem too
when photo taken exceeds 5MB.. it is broken...and it happened too often. any solutions?
Click to expand...
Click to collapse
Ok, that's bad...
For now, I check whether the thumbnail of the just taken photo appears correctly (inside the photo application). If not, it's a sign the photo has exceeded 5 mb. Then I go to settings, reduce the quality, reshoot.
Or, one can use Camera MX and set the quality slider to 90-95. Then the photos are better than stock camera, and they don't exceed 5 mb.
Since noone cares for this problem I can only hope the new firmware automagically hasn't got this problem. If it does.. we'll see then...
Bad news... Just updated to official V20a, and the same issue persists. a 5.02mb JPEG resulted in an image which was half ok, half greyed out and corrupt.
Only hope now a mod, or a custom ROM..
Ok, is there a way mother LG can be notified about this? (and don't tell me phone support in my country, they can only handle basic stuff. They won't understand what I'm talking about and respond like "use the official camera application"...)

Not that I know of.
i have no idea why, but yesterday i took some pictures with my 4x (with the stock lg camera app!).
the most pictures had around 1,5-2,5mb , one hat 4,7mb and one 5,05..
the ->5mb pic is corrupt..
never saw this error on stock, im using stock camera app on my CM
Anyway, i reported this bug to CM on the 4X forum, lets see if they can help. would good if more people confirmed this bug on CM forum..
I have a little experience about this bug.
Last time I flashed google's camera 4.2 with photosphere, camera.tegra.so and libnvmm_camera.so (modded to disable denoise filter) and stock camera. The result was that wherever camera I used (stock, cm, google's) the pic were corrupted (taking photos in dark). Just few of them were OK.
Here are modded .so files - works with CM10.1 (made by me, if you want i can made thread for them):
http://db.tt/2Lfxuehq - camera.tegra.so pasted to /system/lib/hw
http://db.tt/LXdwvJUZ - libnvmm_camera.so pasted to /system/lib
Sth more I will say when I come from holidays.
Guys,
I've started a multi-part article series discussing how the Note4's camera should be used (and how it compares to other high-end phones, cameraphones or even standalone cameras).
The first two parts in the series have already been published:
Part I: http://www.dpreview.com/forums/thread/3781966
Part II: http://www.dpreview.com/forums/thread/3782300
This series will be of particular interest to Snapdragon 805 users. Exynos users, at the moment, will find the series less interesting, as third-party apps, currently, can't access the (almost) non-processed image stream and they, consequently, can't export non-overprocessed images.
EDIT (2015/01/17): Part III is published on HDR: http://www.dpreview.com/forums/thread/3782850
EDIT (2015/01/24): a brand new writeup is here at XDA; you should start with it instead of the previous ones: http://forum.xda-developers.com/note-4/general/shooting-light-best-image-quality-note-4-t3012008
Great. Thank you

How to manually change shutter speed to 1/8s in Snap Camera HDR app? Thx

Basically, if you have an Exynos device, the stock Camera app unless
- you're absolutely sure you don't need shutter speeds under 1/30s (the restriction of many apps, incl. FV-5) and
- you do need the on-screen controls of that app.
Otherwise, the image quality will be the same so there's no advantage in using any third-party app for shooting, as opposed to the Snapdragon case.
If you have a Snapdragon device, you can get far-far better image quality out of your camera in both still and video shooting mode because of the lack of noise reduction and oversharpening. Then, using third-party apps like Snap camera HDR is preferable, assuming, of course, you don't need features like dual camera.

You can't - the pre-Lollipop API doesn't let for directly setting the shutter speed. The device will automatically use 1/8s when there's little light.
You'll need to make sure you do enable the Photo > “Samsung Camera Mode” checkbox; otherwise, it will NOT be able to go under 1/15s, resulting in a complete loss of no less than 1EV. At least on Snapdragons; I couldn't test this on Exynos devices.

Then, if you really want to see in which cases third-party apps can produce significantly better images, you really want to compare my example shots of the stock app to those of, say, Snap camera HDR - see the crops in my article.
Basically, the stock Camera app applies far too much noise reduction and oversharpening, pretty much ruining fine detail and introducing ugly oversharpening halos. Photos produced by third-party apps, incl. Snap camera HDR, are far more natural.
Just writing my HDR article. The first two parts of the new article is already published: http://www.dpreview.com/forums/thread/3782850
Very nice articles. Thanks for doing them.
Is there any way to get rid of the cruddy yellowish look I get on low light photos on my phone? My wife's phone doesn't have this at all, and both of the Note 4s that I have had do. I've been very unimpressed with the low light abilities of this phone, so far. I'd love a solution that doesn't involve sending the phone in to maybe be fixed.

Hi there. It's a nice report! However i do have some input
1. The stock camera does do 1/4s in rare occasions , happens for me when I do shots in not-well lit conditions and yet insufficient for camera to engage in night mode.
2. I have no idea if its just me, but night mode does not downsize my photos to 6mpix no matter how dark the scene is. It still stays at 5312x2998. N910G here. Details of photos on poorly lit scenes do not have significantly worse detail for me as compared to well lit ones and file size is in fact larger by a bit. (the room is still not too dark though).
IMO the stock camera does some sort of multi frame noise averaging technique (similar to canon's and sony's "Hand-held Twilight") to reduce noice.

Wow! Haven't ever seen such an image from my European Snap 805 (F) model. Could you post the original to, say, flickr, or, here as an attachment? (Of course, feel free to remove the location info first from the EXIF data.)

It'd, then, exhibit a much higher probability of camera shake / stitching errors. The relative noiseless-ness is because of the very-very strong noise reduction. (Or, maybe, because of the "G" model you have is somewhat different from the European one? I wouldn't think so - after all, both are Snapdragon-based.)

I've tried all of the settings in the phone. Nothing makes the problem go away. Using the same settings as my wife's phone, and there's a huge difference in the quality of indoor pictures between the three phones.
It does take quite nice outdoor pictures.

Could you take low-light images with an LCD computer screen displaying white
- without(!) using f.lux or other tools to decrease the white balance (this is equal to about 7000K) and
- at both a very low brightness level (to "kick in" night mode) and a high one (to avoid night mode)
with both phones? Preferably in "auto" and "incandescent" WB modes on both phones.

Unfortunately, I deleted those photos as it was blurry due to the unexpectedly low shutter speeds or that the picture sucked. I will post if I can reproduce that setting again.
As for the noise averaging mode...
1. It will not cause camera shake/stitching errors even if you hold still. Why? If you were to shake your phone violently, the software is smart enough to abandon image stacking altogether & the final image produced is the result of just 1 picture that has a little fine bit of extra noise reduction maybe.
2.Samsung's night mode is not well documented, unfortunately, despite them having this mode since Galaxy SIII.
However, the answer lies hidden in one of their support page for galaxy S4
http://www.samsung.com/us/support/howtoguide/N0000003/10094/120418/SGH-I337ZBMATT
"Night: Take photos by combining them to get a brighter, clearer photo in low light, without flash."
Now, you may think that perhaps this mode only applies to the S4's night mode, so I did a mini test.
(click on photos to zoom in)
(1)
Image taken with night mode
(2)
Image taken WITHOUT night mode under same conditions (This is done by tricking the camera to first take a photo in bright light,continue holding down the shutter button to engage burst shot, quickly direct phone to subject and wait for phone to adjust to the right exposure)
(3)
Same image from (2), but edited in Lightroom by dragging the luminance noise slider to like 40.(there is little or no chroma noise, so I did not touch that slider)
As you can see, despite their photos taken under the same conditions, (1) is the best as it as less noisy compared to (2) and sharper than (3).If Samsung really did engage in strong noise reduction at night mode, much fine detail would be lost and the photo will look like an oil painting when you pixel-peep. Thus , night mode photos you take will look more like (3) than (1), when (1) is the actual night mode photo in reality.
3. Another good guess that Night mode is actually a multi frame mode is that, all night mode's photos have their EXIF data eroded.
(Fun fact, dpreview says iphone 6+ does this too)
"the built-in, stock Camera app may have too strong noise reduction and oversharpening"
IMO, Im sorry but I disagree, too strong noise reduction would mean that photos from the note 4 would be too smooth and would lack any fine detail at all, which from my observations isnt true. Samsung excels in that area. Also, oversharpening is also not the case, oversharpened photos often result in false detail and look contrasty/frosty which is again, not the case to me.
EDIT: oversharpening and noise reduction could be a matter of taste so it could be true for some
Hi
Will Huawei fix the overexposed soft image quality of the selfie camera on this phone.
I am still on 8.1.0.103 and wondering if its been fixed in one of the newer updates as it is really disappointing
Not sure they think it's broken, it was obviously designed to do this on purpose. I know a lot of people that use beauty mode. It is rather annoying though as it can't be disabled for those that don't want to be enhanced to Ken doll like proportions lol
If you hit the photo mode rather than the default portrait mode for front camera it does help a bit. Definitely better than portrait mode. I do hope that a future update will add more control over the processing, but I won't bank on it.
I've tried many different camera apps, and the overexposure and softening occur as soon as the camera detects a face. Haven't been able to find a solution yet.

im 99% sure it can be disabled with root - its got to be a setting that detects faces.
we;d need someone to go through the source (if they ever release it)
once i root my p20 ill stalk around to try and find a property.
Sorry, i dont have phone yet. But, if you use some other camera application, will it be the same problem?
Its definitely a setting built into the kernel/source code because using another camera app will not override the setting. It only focuses on the subject (face) and blurs out the background which should not be the case
I have rooted P20 pro, and there is a ton of properties and definitions xml files for different modes and effects in odm/camera folder. For example there is something called "casiobeauty" among others But, to mess with those parameters someone has to have knowledge. So, i guess effects can be modified, if there ever will be someone of knowledge and will to do it
You all may want to install CameraMX from PlayStore.
It gives out high resolution and high qualoty images. Selfies taken by it are noticeably sharper than the p20 pro stock camera. Also, there is a slider to adjust exposure for the front cam (something that is missing from the stock). In addition, the app also supports HDR for the selfie cam as well.
You can give it a try...

For the photos below, the washed out one is taken with the front camera native app. The better one is with cameraMX app.
Note: No editing done, same lighting condition, almost the same hand position, same angle.
It is very evident that the native camera app is washed out/overexposed.
Well, the CameraMX photo isnt perfect but for me, it is 80% better than the stock camera.

Hi, I'm pretty much sure it's a software issue as the original photo can look so much better when you edit it. And, you can also use other camera apps
There is a workaround on the overexposed p20 front camera images using the Google Photos Editor App
(I've read it from another XDA thread).
The results are stunning! It's almost as if the photos were taken using an actual Google Pixel front camera! (In my opinion)
I suppose the image enhancement algorithm for the Google Photos app is similar to the image post-processing of Google Pixel phones.
Note: Google Photos is commonly preinstalled along with Gmail, Hangouts, GMaps.
Step 1 - Snap a selfie using the native app
Step 2 - Preview the photo and click the (...) at the bottom right
Step 3 - Click Advanced Edit ---> Select Google Photos
Step 4 - Select the second icon next to the filters menu.
You will find 3 sliders (Light, Color, and Pop)
Step 5 - Slide Pop all the way up, as well as Color.
You may tweak the settings more for Color and Light too!
(There are more options when you expand it)
Step 6 - Click Save.
Find sample photos below:
Just got a P20 Pro and this is seriously my biggest hate with this phone! The rest is great (except my google pay not working) but the front camera makes me look like a ghost on any image!

Yes, I second that.
Personally, I just realized that even taking photos at 40mp with the stock camera a high compression ratio is applied without any criteria. I took several identical photos and realized that some have a size of 15mb and others were with 3mb. Photos identical with the same settings. I tested other applications and encountered the same problem. Lightroom CC and SnapCamera. Here comes the surprise! With cameringo+ I got files with a bigger size at 40mp. That it would be the right thing to do to others as well. Please take a test and comment.
Hi everyone, I have got some camera issues in my pixel 7. I bought Pixel 7 few weeks ago and today I noticed weird effect when taking a picture of printed document. The text in the very centre of image is sharp, but in the direction to the edges it is blurred and distorted. You can clearly see a shadows behind a letters. Do you have any idea what is going on with this camera?
Pixel 7 distortion in the camera image
Because of the focus features and the camera software optimization of the photos taken by the Google cam, it is maybe not the right app to scan documents.
Check out MS Office Lens for better results https://play.google.com/store/apps/details?id=com.microsoft.office.officelens
Another suggestion is Adobe Scan if you're having issues with text. It's what I typically use for this. Personally, I've never had any issues with the camera taking shots of text.
I face this same distortion issue while using adobe scan app too. I also noticed that google camera is over processing selfies mainly to an extent that the original photo is way better than the processed photo. How to overcome this? Kindly suggest ideas.
