[Q] Colour degradation when editing/moving pictures - Xperia Z2 Q&A, Help & Troubleshooting

I am experiencing this issue with my Z2 running .69 firmware.
I updated upon receiving my handset so i can't say if it's firmware related or hardware related.
To describe my issue, whenever i move photos to photo editing apps, there is a visible degradation of my pictures. I'm labeling the issue as degradation for now, but note that there is no lost of image size or resolution. Instead, the issue is the appearance of green splotches over the image, similiar to the appearance of noise on digital cameras.
This happens regardless of the editing app, it seems whenever the picture is moved to another app, the problem occurs.( E.g. in gallery; share a picture via Instagram or VSCO )
Attached are two images, neither images have received any filter. only difference is that one has gone through 3-4 apps. For clarification, the apps are not the one degrading the picture as it works fine on my GNex.
Kindly open both files and is is pretty evident there is a green tint on the second picture.
Can anyone test if their handset is experiencing this same issue?
Is there some sort of Sony "enhancement" going on behind the scenes causing this?
Is it limited to the Z2 or is this an issue of Kitkat?
If possible, could someone help me test if this is a problem with my specific handset?
kindly move a shot to VSCO or your favourite editing app, don't make any edits but just save the file and compare between the original and the "edited" file. you can try moving the image through 3-4 apps and note the green tint becoming stronger each time.
This is happening on all my pictures, regardless if i took it off the phone or through a dedicated camera and then transferred it over. The colour shift is greatly bothering me as it just ruins the picture.
Thanks.

I just tried with a couple of photos. On one of them the green tint was apparent (on white background) but the other is identical with the original.

Hi, Thanks for doing the test.
It seems there is some form of over aggressive noise reduction when photos are moved. It tries to reduce the noise by smudging it, however it results in the whole image having the green tint.
In your first image, the green tint is actually present, go back and forth between the two pictures and you'll notice the skin tone of your thumb changes slightly.
The effect of this noise reduction becomes over bearing when moving the photos through multiple apps, and it is seriously bothering me...
Furthermore, this is totally redundant, why is there a need to modify pictures that are being moved around? I understand if it's present on the camera's software but to implement it when editing pictures??
I have contacted Sony regarding this but they simply asked me to do a Factory reset which won't solve the issue. I have asked them to push this to the software team, hoping it is removed in the next update.
If there is a more direct way to contact the Sony android software team, kindly let me know, thanks.
If However you are not experiencing this, do let us know as well so i can decide if i should send it down for repair or not.

Could more people test this issue?

It seems more than just colour issues.
There are tons of compression artifacts in my pictures, making smooth surfaces appear blotchy.

[Q] Camera picutres come out darker in gallery vs on screen?

Hey guys, I haven't seen this question asked outside of the CM7 Thread.
I have UnNamed 1.1.0 Which to my knowledge is identical to stock when it comes to the camera aspect.
When I'm taking a picture it will look great on screen but when I go review it in the gallery it looks almost twice as dark. Almost like the shutterspeed is too quick and wont let enough light in. Outdoors the problem isnt too persistent. Just indoors. I'm going to try another gallery app and see if that help but doubt it will. Anybody else notice this?
I was actually playing with the camera last night and noticed this.
Tried adjusting the ISO and exposure and it helped a little. I noticed that after viewing the picture though, it still turns out a few shades darker than it does in the live view. Not sure what thats about.
I'm seeing this issue as well. Any resolution?
I noticed this too, not only that but there is a slight delay from when you hit the shutter.
Seems like any movement screws up the picture as well.
I think the brightness discrepancy has to do with the screen brightness settings.... try setting your brightness way up, then take a photo and see if your exposure "gets darker".... it should be the same as how it looked when you took the photo...
I think when you take a photo, the camera app automatically brightens the screen to the Max... then when you go to review the photo, your screen brightness settings take over... since most of us use the phone NOT at the highest setting, it makes the exposure look dark....
The same theory goes for anyone editing photos... I always brighten my screen when I edit the photos...that way I'm not adjusting a photos exposure if it doesn't really need it... this needs more practice though as I don't edit often and could be wrong ...
If you're having lag in the shot... try turning off the anti shake option... you might think anti shake can ONLY be good but I find that my photos are fine without it.... but I also know to not try to take photos in dungeons...
Thanks ill try it

[Q] Camera app viewfinder distorted in widescreen mode

I've been using the Ressurection Remix ROM on my S2 ever since v1.0 and I've only noticed this problem when the ROM moved from ICS v4.0.3 to v4.0.4. I would've reported this problem earlier but I figured, since the ROM gets regular updates, the problem would've been fixed by now.
Whenever I take photographs with my S2, I always have it set to 6.5MP Widescreen. Previously, when the phone was un-modded and when using Ressurection Remix versions that used ICS v4.0.3, the image in the on-screen viewfinder matched the resulting image I got when I took the picture. However, since ICS v4.0.4, the image in the viewfinder is distorted and, in contrast, the resulting image when taking the photograph is cropped. It makes it difficult to take photos since the image I get doesn't match what I see on the screen when taking the photo. I can also report that this is only happening for photographs. The viewfinder picture when recording video appears to be fine.
I have included two screenshots to illustrate the problem, and I have used one of my Union Flag cushions as an example. The first screenshot shows the cushion in it's entirety. Note the gap at the top and bottom of the viewfinder image. At the top, you can see part of my TV, and on the bottom you can see a row of keys on my laptop (which I used to prop up the cushion for this example). The second screenshot shows the resulting image I took when I kept my phone in the same position used for the first screenshot. Notice there is no gap on the top and bottom of the image now. When I compare both these screenshots to the actual cushion, the resulting image appears to have the correct aspect ratio but the image on the viewfinder seems to be vertically distorted, or "squished".
Is anyone else experiencing this? Is there a way to resolve it?
Does it on mine too in 6.5Mp mode
I just checked it out on mine here I am on 2.4 it doesnt seem to cut anything off on mine on 8Mp but it does do that on the 6.5Mp mode. must be a glitch.
I agree, the problem doesn't occur with 8MP photos and only happens in widescreen mode. I'm kinda glad to see someone else is experiencing the problem, as it suggests its something that could be resolved by the developer.
I would comment on the main Resurrection Remix development thread but I haven't posted enough yet.
[UPDATE] I've installed Resurrection Remix v2.5.2 and I can confirm the problem has been fixed in this version

[Q] Image rotation in picture messages and camera displays image differences?

First specs: Samsung Galaxy S4 (Verizon) running rooted with GPE ROM.
The issue occurs on every ROM I have tried, including TouchWiz, and its driving me and my friends INSANE.
I've attempted to look into this issue and I can't seem to find a good answer on this. Whenever I take a picture in portrait mode, the image rotates in the message to landscape mode. Not only that, but if I take an image holding the phone with the lens to the right the image appears upside down.
The image displays correctly in the gallery. However, if its transmitted in any capacity, it will always display upside down unless edited to display the correct way.
To make matters worse, if I take an image with flash, the camera will flash, show the adjusted "flashed image" for a second, and then immediately show me a different looking image, almost as if it was a "pre-flash" image. Many times, the image will look completely different on screen but when downloaded or transferred, it will look completely different. Lighting and all. In other words, the image on screen looks different than the image that was taken, making it almost impossible for me to tell what the image looks like until its transferred. Sometimes the image on screen looks better than the actual image taken, which is why it infuriates me so much.
Does anyone know what is causing this to occur and how to fix it?
I am just noticing this myself. Super annoying!! Anyone have any insight on this?

Nope, I posted this awhile ago and no one has responded to it but you.
I've found some mentioning of it being reported on the Galaxy S3 dealing with the hardware and then some excuse about fragmentation. There were comments regarding "well why are you taking pictures in portrait anyways?"
I hope that someone else has some more information than I do at the moment.
Usually when you take pictures the camera detects the orientation and physically rotates the image accordingly, as well as saving the orientation data as EXIF metadata. Samsung have apparently decided to only include orientation metadata and to NOT have the camera physically rotate the image--probably to give the camera better performance. Some apps are smart and will read the EXIF data to rotate the images correctly...most don't.
Unfortunately, this seems to be a hardware thing. Unless Samsung release a camera firmware upgrade with this enabled, or there's a way to force enable it through software, we're stuck using landscape or manually rotating.

I'm on stock TW (ME7)...I haven't noticed the rotation issues, but I definetly have the before/after issue where the picture looks different. It is super annoying and my wife always complains that my photos look too dark. I asked my question a little while back in this thread (http://forum.xda-developers.com/showthread.php?t=2421173). I would love to know how to fix this!!

Can you do me a favor? Take a picture in portrait mode, then download Solid Explorer, browse to your camera storage directory, and tell me if the thumbnail for the image you took in portrait mode is correctly rotated?
Sure. Once taken in portrait, the "preview" image shows as landscape in the detailed list of files, however, upon opening the image in SE Image Viewer, it displays the picture in portrait correctly. I also have QuickPic and ES File Explorer installed. QuickPic shows the image in portrait correctly as well, but ES Image Browser shows the image rotated to landscape (incorrect).
Thanks. Since you were stock I was wondering if there was a camera firmware update problem for people who didn't take the official ME7 OTA. Looks like not.

RS988: Is my camera defective (Snapchat)?

Hey all, so I got the unlocked US model of the G5. First thing I noticed is a scratch on the back on the paint near the camera. I was upset, but thinking if I returned it, I'd get something worse back.
Anyways, when I went to use Snapchat, I noticed if everything is on the dark side I can see some lines on the video/photo viewfinder and it stays in photos/videos if it shows while recording. So far this only appears to happen in Snapchat, so I'm hoping it's something with the app, as it doesn't show in the stock camera. (See sample video below)
Can anyone who uses Snapchat check if this is a thing?
Sample: https://drive.google.com/open?id=0B8OF-gTbFNmSVVdLSlAtdGdYUWM (that's South Park in the background fyi)
Thanks for any input!
I think if you have your phone in any version of English other than US, it will change the anti-banding setting in all camera apps. I can't watch the video right now, but it sounds like what you're describing. Snapchat is working just fine for me.

I don't think that's the problem. I'm in the U.S. and have it set to U.S. (just tried UK, as well).
It comes and goes and only on the right side of the screen.
I noticed also in the stock camera app it seems the viewfinder "lags" (has lots of motion blur) while taking photos., causing some photos to come out blurry. This never happened on my G5 H815.
My snapchat is the same, I get those lines down too
I have a Verizon G5 and have those exact issues in Snapchat. Strange, dully colored vertical lines when moving the rear camera, and a dark front camera.
The front seems to be a bit better from an update, but I'm thinking they have no idea how to code for the dual cameras.
I have the same problem on my g5 rs988
Update your Snapchat app, the issues I use to have is that front camera flashes on snapchat when trying to use it in low light photos or rooms, inside places, etc. Otherways the photo came extremaly grainy too, but no that lines.
Later I joined beta and it seems solved now i dont see that flashes from black to light or grainy selfies, even the resolution looks like normal camera even in low light
Same for me with G5 H850
The snapchat camera is fixed now.

Wierdest side effect I have ever seen

Hi guys,
as the title said I am experiencing a glitch with my phone. The good news is that it occurs only a few times a year but I was wondering what's happening here. The side effect only occurs when I turn on the screen and vanishes on the next screen turn on. When I try to screen capture this it results in a "normal" screenshot (i.e., the side effect isn't visible). Clearing the cache doesn't seem to help. Here is the video (https://youtu.be/vZ0cBGjlBlM). Photos are attached bellow for a sharper picture because YouTube downgrades video quality.
If some of you didn't notice, the background photo on the "grayscale" image is the background photo I attached below (what should the phone actually be displaying).
Thanks for your help!
