I have trouble with my Huawei mate 10 pro when capturing photo.
Sometimes appears vertical lines moving across the screen while capturing photo.
you can watch the video that I mentioned the problem:

Is that a bug, software/hardware error?
Should I take it under warranty?
Thanks,
Thats due to the shutter speed, happens on every camera.
It is due to the TV flickering to create the image, happens with LED's most commonly.

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.
Anyone notice that one the T-Mobile Edge, that when you set "Video Stabilization" to "On" it actually doesnt stabilize the video?
Only when you set it to "off," it'll stabilized the video recording?
It's kind of the opposite, not sure why no one else noticed.
Could be wrong here, but I believe that while recording you not going to notice any stabilization. It's happening but you won't see it until replaying the processed video after the recording is done.

To check video and photo stabilization, try zooming in to 3x, point it at something and try to do a recording with it On and off, the video will do the opposite.
It work none the less, but it's counter intuitive to have it day off when it's actually on.
OP seems to be spot on. Same problem with my regular S6. Video stabilization = off turns stabilization on. With it = on, videos are jittery as hell where even my pulse through my fingertips causes the camera to shake.
So guess there's a bug in the camera app.
I just noticed the same thing with my unbranded regular Galaxy S6. If you have video stabilization turned on in camera app settings it is in fact turned off. I was surprised how poorly it stabilizes the video, so I had to use 'Stabilize' option in YouTube. Then I thought maybe my optical image stabilization component is damaged so I started playing with it and once I turned it off my video stabilization started to work very well. So it seems to be a bug in camera software. Anyway - if you want to have video stabilization you need to have it turned off Samsung logic
The reasoning is because the video stabilization setting in the camera app turns on DIGITAL Image Stabilizing by Samsung via software which is really just counterproductive to the Optical Image Stabilization already built into the camera.
So yeah, trust the OIS hardware because typically hardware > software in this field.

Just a question so OIS is default by default and always on am I right? Even on UHD recording?
More evidence that the switch in the camera options refers to DIGITAL image stabilization:
Set video resolution to FHD (not the 60fps option). Otherwise, the Video Stabilization setting is not available (grayed out).
Set the Video Stabilization setting to "ON".
Go back to the camera, zoom in fully (8x). While pointing at something easily identifiable, without shooting video, note that the image is stabilized quite well -- you can simulate "shaky hands" and the image is very stable, not jittery. However, you are not shooting video yet, so settings specific to video are not activated. What's happening here is the OIS is working, and doing a very good job.
Now, click the video recording button. You will notice two changes in the image: It will zoom in a little bit more without any zooming input from you, and the image will get rather UNSTABLE.
It turns out, what you had selected in the settings is actually, truly, being invoked. No, this is not a bug. The switch is not acting the opposite of how its labeled, even though the RESULT is exactly that in practice.
Here's what's happening: As someone else noted, that switch controls digital image stabilization. This is a software process, that basically crops off a small margin all the way around the picture and reserves these pixels for calculating a smaller moving "window" in the larger captured image space. The software tries to move this window around so that it follows the random small movements from jiggling, unsteady hands, etc. In this way, the image appears stable rather than moving around in the capture space.
This is why, when DIS is turned on, the displayed image zooms a little bit -- that's the "reserve image edges" being cropped off and the remaining image being expanded into the display area.
So, here's what I think is happening: When you have Video Stabilization on, the phone turns off OIS and enables the DIS algorithm. The OIS camera hardware is something like a Googolplex times better as IS than Samsung's crappy algorithm, so the end result is the appearance of IS being turned OFF and a little loss of resolution of the video image as well.
Once the video is stopped, after a few seconds you'll see the DIS turned off, OIS turned back on, and the image will zoom out a tiny bit and become very stable again.
Bottom line: The Video Stabilization setting in the S6 camera app is worse than useless. It's adverse. It should be left off at all times under all conditions.
How did this happen? My guess is, the engineering team responsible for the hardware was organizationally distant enough from the camera software team (keep in mind the latter are trying to develop an app that can run across many phones). The hardware guys put this incredible camera in the phone with awesome OIS. The software guys, not focused only on the S6, passed through the DIS that's been in the camera app forever, and no one engineer was responsible for integrating all this stuff for the camera feature itself, testing it, making sense of it, blah blah blah.
And here we are.
Bottom line: Because of the OIS in the S6, the DIS feature in the camera app is unnecessary and should be left OFF. In fact, the way it works misleads the user into thinking IS can't be had with the video resolutions higher than non-60fps FHD. In fact, exceptional IS is available at all times in all resolutions for stills and video -- the hardware OIS is always on the job, unless you turn it off by turning on the [digital] Video Stabilization option in the settings.
The only bug here, if any, is that this setting seems to turn off OIS, when it doesn't need to. Perhaps with OIS on, and the DIS processing applied to that stabilized image, we might get something even better than OIS alone. Alas...
Hey guys. As you can read in the title its about some problems i ran into when using the camera. Using the official v3.88 rom btw
For example
Video recording
4k records in laggy 15 fps in good light, 11 fps low light
1080p records 24 fps in good light, 11 fps in low light
For 720p its the same as 1080p
Photography
I have focusing issues when using automatic mode on macro and/or close up shots. Camera tries to focus, then focuses beyond the sweet spot (meaning its sharp but it still adjust focus beyond that so it gets blurry again), and then it jumps back to what the focus was before. Happens very rarely that it stops the focus where it should be to get a good picture.
Now for low light and complete dark conditions using the led flash.
The focus issues here here are similar to the previous macro/close up issue.
Example scenario: complete dark room, camera with flash led enabled. Now when i try to take a picture using the shutter button (not onscreen one as this just shoots without attempting to focus at all), the led turns on, camera tries to focus, led turns off after focusing, focusing indicator appears again somehow (orange square), now i press the shutter down completely, it takes the picture and it comes out really blurry as it resets the focus right to where it was at the beginning (thats what similar to the macro shots).
Does anyone of u guys have these problem on the same rom (v3.88)?
Do any Mini and Max users here have similar issues?
If u have time pls try out the things mentioned above (video and photography pls) and post your results if you have the same issues or similar things happening to you.
Anyone?
Guys, pls. Already 170 views and nobody answered. This goes to anyone. Max, mini and normal z7 users. Pls tell me about if u have got camera issues or not on the latest available stock rom on your phone
I'm having the same problems with videorecording, low FPS in low light, like 10-20. Im using Resurrection Remix 7.1.1 though, i dont rememeber if this happened with the stock version i had (3.84). Have you found any fix to this?
Edit: i´ve found a workaround for the low FPS in low light. You have to set the "exposure" setting to -2, it will make the video darker but you will get a stable framerate.

Thank you for responding. Yeah i know its due to exposure being too aggressive while video recording. What about taking pictures in low light (or even in a completely dark room) with led flash on? Does it focus correctly and captures a sharp image or does it kinda reset the focus after led turns off and gives u a blurry result?
And what about 4k video recording. Does it give you stable 30 fps in good light conditions? I know mine didnt.
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!
I have started experiencing this issue with my galaxy s9+.
The camera no longer capture those impressive shots which it used to capture last month or until few weeks ago.
Now the photos are blur and focus is very bad.
Anyone facing similar issue.
Can anyone help me fix it?
My camera is capturing photos, the shots which it used take were very impressive and now the quality has become very bad all of sudden.
Please see the 1st photo in white t-shirt. It is few weeks ago.
The second photo in black t-shirt is captured now. It is very blur. No matter how many times I try or change location or light condition. Photos are very blur and focus is very bad.
FYI... I reset the camera settings and clean the partition cache several times.
Thanks for your help.

To see if it's the hardware or the software, I would suggest you try the same photo setup with a DIFFERENT camera application to see if the problem is in all the camera apps or in just the one you're using.
Each camera app will have its own set of settings which may help you debug, e.g., the GCam port has these settings screenshotted below which can help you debug such as "dirty lens warning" and resolution setup.
But the SIMPLEST camera app to test might be this FOSS camera app from Mark Harmon. If that doesn't work, nothing will.
There is also the free "camera2api" probe utility program which may provide hardware malfunction indicators.
