CM12 Black Camera Issue - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

Hello, on every single recently nightly I've tried for CM12 on my trltetmo Note 4, many apps can't use the camera correctly. Stock camera of course for the most part works, though HDR doesn't actually take a HDR photo at all. Mainly, what really is the big issue here is, FB Messenger, World Lens, and FV5, all show a black image for the camera. But here's the kicker, with FV5, you can enable widescreen viewfinder, and it shows an image, but the shutter button doesn't do anything. Another interesting quirk is, World Lens, though showing you a black image, DOES actually show translated text when the camera is aimed at words, so the camera IS doing something, but you simply can't see the image. I don't know if this is all related to the other issues.
Since we can't really talk to the devs at Cyanogen mod about this issue, I have no idea if they are aware, or are fixing it. Known issues page doesn't even mention it one bit. If there is actually a fix for this, like something I can flash in recovery, or simply missing libs, I would be greatly appreciated, because for me, there is literally no other issue with CM12 for me, except this one thing.
Thanks!

Camera settings inquiry

Apologies for cross posting, also posted on HowardForums.
Does anyone know what the camera settings actually do? I mean specifics.
For instance-
Is changing saturation to 1 effectively converting the image to grayscale or is color data preserved?
When it comes to contrast, is 3 a linear curve? What sort of curve is applied at the other settings?
For sharpness, 3 is the default. Is changing the setting to 1 or 2 simply appying less sharpening, or is it actually softening/blurring the edges?
Are other image formats besides JPEG supported and just not enabled? Lossless formats perhaps?
I know we are not talking about an amazing camera, but I would love to be able to find a baseline to work from. The closest thing to raw, unaltered data with some level of consistency between each capture would be absolutely wonderful.
I see myself using the GPS Photo feature on the Tilt quite often, especially if I can tweak the camera settings.
Thanks!
hi guys,
i would really appreciate if any of you could tell me is just me or others facing the same problem. I've set the saving pictures taken as storage card but each time i take a ew photo, it shall show as unsupported format or corrupted file when i want to view t using pictures or resco photo viewer. why does it take so long to go back to camera after taking a picture especially if set it to storage card as default. hope any of you could help me. thanks.
I'm guessing your storage card is corrupt, try reformatting it.
You can change the amount of time the capture review stays on the screen, if that's the other issue you are having.

Yes absolutely right. I've never seen the point of reviewing the pics one at a time anyway. I've set mine to zero and it makes a huge time saving between pics.
Apologies to the OP for a somewhat hijacked thread - don't know the answers unfortunately.

[Q] Camera pictures sharp then soft

I've posted http://forum.xda-developers.com/z3-compact/help/z3-compact-camera-z1-compact-t2899172 but having spent a couple of days I wanted to see if other are having the same issue.
Basically.. when I take a photo in any mode, the initial capture looks great, but then 0.5-1 second later Sony 'processes' the image and it looks worse 9 times out of 10. Example is if you take a picture of your hand, the initial capture shows all the skins imperfections and looks really good on the screen, a second later, it looks softer... I am not using 'face soften' or anything like that either.
Why is this the case? Can you disable the processing? I can't believe this got through Quality Control, surely people in the product testing group would have noticed this? Seems a weird flaw in the software...

I totally get what you mean. It's as though when the shutter is half pressed, everything is in focus. Then when you snap, all goes blur.
I was attributing this maybe to my shaky hands, but apparently I'm not the only one having this problem.
More often I experience what you said in Manual mode. My photos are better in SA mode.
Sony Soft skin effect ruins all pictures of people
You are 100% correct. Sony has put a soft skin effect (some asian girls love it) on all pictures of faces. It automatically ruins your picture and makes it look fake.
I'm a professional photographer, but the new Xperia phones are so "smart" that they are useless on portrait pictures. Sony MUST fix this.
You can not take a normal picture of any face with the Xperia Z3 or Z3 Compact. Nobody should buy this phone before Sony fixes the issue with "Soft skin".

I've experienced the same thing as the OP on occasion. Sony has always had rubbish jpeg processing that destroys details, even in its high-end cameras. I really wish it would offer the option of switching noise reduction and other processing algorithms off. The Z3c camera is capable of very good quality, but the software makes taking any photo a hit-or-miss experience (janky white balance, incorrect shutter speed/ISO for scene, over processing of jpegs, etc.).
I renamed the iAuto mode to uAuto (aka Unintelligent Auto)
Does this processing still happen if you use the Google Camera app instead? My understanding is that these processing algorithms are sony-app specific and if you unlock the BL and lose your DRM keys (thanks a lot sony), you no longer get sony's denoisification/etc processing, at which point the sony camera app will behave just like any other camera app that doesn't have access to sony's processing.
This is a terrible "workaround" as sony doesn't give us a way to set google camera is default - and we can't disable these features in the sony camera app.
I've got the same problem even if I use the google's camera instead of the default one. I don't understand why we're allowed to turn off this soft skin effect even if we "turn off" with the button on option. I really hope Sony is going to fix this because it's so annoying.
Lets wait for the new android L as it will come with raw image support, so hopefully this will be a fix .
http://www.androidauthority.com/nexus-5-lollipop-camera-api-samples-540858/
And have hdr mode on 20meg pics with a toggle option. In fact the whole hdr function needs work. Its currently pathetic.
I also hate this softening. I was wondering if it would be deactivated by loosing drmkeys.

It would be preferable if Sony had software that took decent auto-mode photos in the first place. RAW support would be nice, but half the time I don't want to be editing photos, I just want to take a quick photo and post it online. Preferably an photo that's sharp, with decent white balance, some detail left at high-ISO, and no pink spot in the middle -- four major things that are not guaranteed with the camera now. Not to mention the fact that the file size for a RAW 20MP image (often over 30MB) will lead to storage space filling up fast.

Storage should not be that much of a problem as you always can expand with the SD card if you need to.
Nevertheless i agree with you, but since this softening effect can also be observed on Sony cameras i doubt that your wish will come true.
What RAW Image support will hopefully bring is better camera apps which process and compress exactly in the way you want without further modification on a computer (as we are basically already running around with a small computer). This of course will still take some time and effort but is very likely to happen.
So i guess we still have to live with this a couple of months .

Galaxy S5 camera versus iphone camera

I really like my S5 but when it comes to using the camera it looses personal every comparisson with the iPhone. Not only versios iPhone 6 but also older ones.
Either the Camera lags when I launch it and is not ready fast enough to catch the scene
Or from picture to picture I have to wait (I do have a fast sd card)
And ultimately (and this is my major complaint) all point and shoot pics are vivid and sharp on my friend's apple devices but not on mine. I can make pleasing pictures but I do have to make sure I hold my phone dead steady and bother about whether to use flash or not since relying on auto doesn't always do the trick. And focussing seems to be really slow in comparisson.
I have tried alternative apps but my shap shots are rearly as crisp as I would like to have them.
What is your experience? Or how can I improve this?
Buy an iPhone?
But seriously, it sounds like a problem with your S5, I have none of those problems, and get great pics without having to hold the phone perfectly still
Camera launches quick, photos switch perfectly smooth and fast too

Cheeky
No .. actually I really dig the freedom Android gives me and since there are so few complaints I thought this thread could bring some insight. I know that my phone is quite packed with stuff and that having a ligthweight system could probably improve things a lot.
So hopefully there will be another entry or two that may enlighten me
I find the S5 camera captures pretty amazing shots in good lighting., especially outdoors in the day. At night and indoors with poor lighting, I am not that impressed with the camera. But overall it's an impressive phone, and I will never trade an android for an iphone, due to android's freedom to customize in way too many aspects.
I now found out that automatic night mode may be what's diturbing me. It is said to be degrading the overall app performance. Will see how it goes without.

I find the stock camera app fast and shot to shot (with auto night mode disabled) is fast.
However, I don't use it at all. Here's why, Samsung has a very aggressive noise reduction and sharpness that makes things look really ugly. In day light it isn't too bad but still noticeable.
If you want to unleash the capability of the camera, download Snap Camera and go to "Other" in camera settings and enable "Show advanced settings" and "Use OpenGLES 2.0" (don't enable camera2 api). Go back to "Photo" and put a checkmark on Denoise and remove the checkmark. It doesn't have a checkmark originally but it doesn't seem to disable it until you check and uncheck it. You want it to be unchecked so that it removes noise reduction. Also, check zero shutter lag and check Samsung camera mode.
Next, put the sharpness to 2 for balanced sharpness, or choose the one you want, note that after 3 images will be over sharpened.
This camera app has many features and settings, even the ability to choose what quick buttons you want. It's also fast!
Images look realistic. You will have noise all over but that's fine, at least all the details are visible.
Let me know what you think after you do the above.
Thanks for the instructions. I did first steps with Snap Camera but I cannot decide yet wheather I like denoise more than not to denoise .. I will have to do some real life tests. I do notice though that some features of that app need straightening out. It cannot write to my SD card directly and "touch to capture" is also not working. And I must admit that I miss the small preview pic I have in the stock app. Please don't get me wrong .. I have tested several camera apps so I will also gladly look deeper into this one. For a while A Better Camera has been my favorite and I also tried Googles Camera etc. Regardless of what I tried out in the end I always returned to stock.

Stock ones are always my favorites as well. I tried to find a way to remove the noise reduction using build.prop but I couldn't figure out how. For the HTC M9 that I have I can do that and use the stock app, which is awesome.
Did you try shooting to internal storage vs sd card using stock Samsung camera? Maybe it will be faster than SD card. On my M9 when I shot a raw it took 2 seconds to save in internal storage (38MB each) but when I tried saving to my Sony 40 mb/s class 10 micro sd card it took longer so I only use internal storage now, even on my S5 (though I don't have as much space on it). How fast is your SD card?
i feel like the iphone camera isnt that great plus smooth video on galaxy s5 is a win

I have a Samsung Evo+ 128MB ExtSD and and it doesn't seem to be a bottle neck. Plus I use FolderMount anyway so in fact it doesn't really matter which device I set up in the cam app since it is a link to ExtSD anyway.

Google Camera/Gallery Issues

I finally received my 4XL and have been setting things up. I decided to take a few test shots with the camera and noticed a strange and concerning issue...
When I take a picture and tap the small viewfinder icon on the bottom right of the camera UI, there is a blurred version of the image and then it just goes black. I can still see the share and delete icons on the bottom but they do nothing when I tap on them.
After about 10 seconds, it will finally load, or I'll have to navigate out back to the camera viewfinder and then back again to the gallery to see the picture I took.
Selfies are even worse (particularly portrait mode). They just disappear after I take the picture and I have to redo the same troubleshooting steps described above. However, I have to wait a full 30 seconds or so before the portrait mode selfie shows up.
I've tried clearing data and cache of both the Camera and Photos app, uninstalled updates, rebooted into safe mode, tried with the stock kernel and Kirisakura, to no avail.
Anyone else having this issue? I'm trying to see if I can resolve this without resorting to a factory reset.
EDIT *RESOLVED*
It was my fault. I had Tasker set to move pictures from the default DCIM folder to a different folder of my choosing, once the Photos app opens.
I guess viewing a picture after taking it is technically part of Google Photos, hence why it was going black (picture no longer exists in that location or not enough time to process the image before it gets moved, thus corrupting the file).
This thread can be closed but I thought I'd share the solution in case the rare chance anyone else has a similar Tasker setup to mine.

How does the panorama mode work in the stock camera app?

I must say I'm impressed. Quality aside (it's still a phone camera), the images are seamless.
Can someone explain? Does it just lock ISO etc. and use the decently fast RAM and CPU to speed things up?
Just to make it absolutely clear, I'm talking about this app.
HELLO Wrt34u7, I capitalize the magic word when you ask for info or help.
Also know on which devices you want to know how to use the panorama.
Thank you for specifying
