Camera stottering - New rom / kernel a solution? - Nexus 6 Q&A, Help & Troubleshooting

Hello,
because i bought a new phone i gave my "old" Nexus 6 to my wife. Since a updated to Marshmallow i had problems with the camera. It stuttered while making a video. But i dont often used the camera, so i ignored it. My wife is Snapchat addicted and she can't make good videos with the front camera of the N6....it's like a slide show....the record is not smooth. I searched at the internet and a lot of people have the same problem since Adnroid Marchmallow ....
I flashed her CM 14, because i thought it might be a problem with the stock rom , but the problem remained. So my question is. Because i know i had not the problem at Android Lollipop. Is there anybody who had the same problem and solved it with flashing another rom? Or is it worth to try another kernel? I looked at the "rom forum" and found the "sky dragon 5.0 with a "new" kernel and probably i will try this. So my question is....is it a problem with the rom? is it a problem with the kernel? is it a problem with the hardware? What you expert think its the best way to fix the problem (i tried tips in the internet like diasble geodata at the photos or disable the battery safer for the camera app).
I hope you are able to understand my english. Otherwise i will explain it in other words.
Thank you very much!

Flash a factory image (will wipe the phone 100% but take it back to bone stock). If the camera issue is present on stock rom, stock kernel, with no modifications, then it's a hardware issue.

i have had problems with stuttering camera app before but it was fixed by resetting the phone. not really sure why after installing a new ROM you still facing this issue.
have you tried other camera apps? download a free one from the store and see its the same deal.

My first Nexus 6 had no issues whatsoever. When I had to RMA that one for the massive battery bulge issue, my second Nexus 6 had the camera stuttering issue. It would happen whether I was taking still shots or video. Obviously it was more noticeable on video, but it still made taking stills difficult. I took a video at the time to post on here to see if other people where having the same problem, but actually never got around to posting it...

Anyway, I RMAed that phone for the camera issue but then the third N6 had the same issue. I decided to live with it though since (a) Motorola has a really frustrating return policy/procedure, and (b) since two different devices had it I didn't think there was any guarantee that an RMA would fix the problem.
Fortunately, I've noticed that lately (running Nougat now), the stutter has mostly gone away. I'd say that for still pictures it has gone away entirely. For videos, I think it is gone as long as you use the stock camera app. I've noticed that if you use other apps, like Instagram for example, my video still has issues. In that case though, it's more of a constant refocusing issue than a stutter issue.
So moral of the story is... for me at least, it seems to be ok on Nougat as long as you stick to the stock camera app.

[Q] CM6 camcorder focus

So last night I swapped out my Milestone for my Nexus One because it takes better videos in the dark... and I was hoping to film some performances on the closing night of one local nightclub in town.
The first few videos turned out really fuzzy and I was frustrated because this had never happened before I installed CyanogenMod 6. I quickly Googled the issue and found this:
http://forum.cyanogenmod.com/topic/5336-cm60-stable-no-video-focus/
So I tried the workaround - enter camera mode, touch to focus, then back to camcorder. Worked sufficiently well for my needs, but it really sucks that I lost out on the performances I filmed before I tried this.
One poster reports on the thread that flashing the Korean radio seemed to fix this. I had earlier installed Paul's pre-rooted FRG33 ROM and this included a radio update which is now still on my phone after reverting to CM6 (baseband 32.4100.32U_5.08.00.04). Thus my experience is that this was not fixed.
Anyway, has anyone managed a better solution than this workround? Thanks!
Not sure if this fixes your problem but cyan tweeted this earlier today
cyanogen: Just wrote touch-to-focus for the camcorder. Even works while recording. Suck it iPhone

[Q] Camer preview flickers

Good day all,
I got my Z1 and updated to 4.4.2. Its a non rooted one. I have issues in camera. The camera preview itself flickers all time, even though pictures taken were clear. I tried clearing cache and data files, factory reseted too; didn't help !!! I Is there any way to overcome this bug?
Thanks!!
Reg,
Raj.
Not sure if this is what you mean, but I also have a lot of noise in the viewfinder/camera etc. (hard to describe exactly but sort of like watching analogue television not quite on the station correctly).. have never seen this on any other smartphone..
My phone is brand new.. seems to really only be a problem indoors/low light etc..
Does everyone have this? coming from an S3 its a bit off putting.
Flickers in camera preview
Yea exactly the same as you told. Is there any app or something to fix this ?? Does rooted phones also has this issue?

There is no difference in Rooted or Not, this is related to the Update, one of many issues. I think there is no fix, just try different Rom, even stock.
Camera Preview not working
since lollipop my camera preview does not work. I can see the small thumbnail but it will not open

[Q] Colour issue when recording video - re-flash camera firmware?

I am having a problem with my HTC one M7 (Rogers) . I am running Android Revolution HD 84.0 (and I have tried the last couple versions without any change in the problem). When recording video the colour information seems to be horribly skewed relative to the brightness data. The screen shows the video properly, the problem is only visible when playing back the video. Here is a video of the problem, and yes I see the irony in using a broken camera to record a video of another broken camera:
It looks like it is either reading a bunch of garbage data before the colour data, or starting partway through the colour data and reading off into another section of memory (I don't know if it is read top to bottom or bottom to top).
I tried changing ROMs and cycled through the last few versions of ARHD without any change in behaviour. I did a factory reset and there was no change. I am not sure what provoked the problem as I don't frequently review my videos so I don't actually know when it started but it was in the last 2-3 months.
My hope would be that the next step is to re-flash the camera firmware but I haven't any idea how to do that on this phone or where I would obtain camera firmware.
Has anybody run into this before? What should I try next?
After some searching I see 2 other people have had this problem with no solution:

This is a known issue with the HTC Camera App. Not a Rom issue or an problem with your camera.
Recording at 1080x720 works fine. It was something to do with HTC implementing the eye experience on the M7 Camera app. You can replace the camera app with an older one but you will lose the eye experience. Or record at 1080x720

I wish known issues like this were better disclosed - I could have avoided wasting people's time.
You seem to be correct, I have changed to the google camera and it seems to be working properly.

[Bug] Snapchat/third-party camera apps choppy recording

Purchased a new P9 Plus the other day and installed both Snapchat and Instagram. Went to take a video in Snapchat and as soon as I started recording the recorded frame-rate dropped to ~10fps making for a nice slideshow.
Also noticed this occurred in Instagram so it is not isolated to just the one app. I must also point out as soon as the recording started it seemed to zoom in slightly, unsure whether this has to do with the lens crop-factor or what.
Original camera app works just fine without any choppiness in recording.
This leads me to believe that it's something wrong with the firmware and makes me curious as to whether there is a solution out there (as I use Snapchat on a daily basis and this purchase was meant to be an upgrade, not a downgrade.)
Current version: VIE-L09C706B102
EMUI: 4.1
So using even more third party apps I am relatively confident it is instead just a Snapchat and Instagram related issue as other camera apps on the store don't seem to exhibit the same symptoms.
Submitted a bug report to Snapchat in an attempt to get it fixed. However I'm still convinced with a tweak somewhere in the Kernel and a rebuild I could flash a version that solves the issue. Anyone have ideas about where to look?

FWIW, I recorded a Snapchat video and it come out perfect. No choppiness at all.

I also have a highspeed Class 10 microsd card that I use as the default storage. Not sure if that would make a difference.

Ah right yea see you're on a much newer firmware version than I am (FYI I don't have a microsd in my device atm). I'm stuck with B102 here in NZ which is what I think the issue is. You wouldn't happen to know an easy method of debranding my device and potentially swapping to the international/EU version would you?

I just got my phone a few days ago so I haven't done much in the way of researching how to root, but I know you can root it.

U should post this on P9 Plus forum, this is for P9.
Had the same problem, updated FW to EVA-L09C432B166, has up to Android Snapchat standards ever since (still kinda slow, but you know, some devs just don't like Android).
Do you guys have the same where it zooms in upon recording as well? I'm guessing this is because of some resolution change, but it's way too zoomed for my taste.

Concept Marshmallow vs. AOSP Developer World

I'm way out of the loop on this phone right now, it's my wife's. But she's been running the Concept Marshmallow Edition, and is currently on build mob30m.z1.3633-somc
It works ok overall, but we have a couple camera issues. Specifically, the video not recording and videos not playing back. A reboot fixes the issue for a short time, but then it creeps back up within a day.
Does any one know if the AOSP build available on developer.sonymobile.com is a better route? I can't imagine reverting her to Lollipop at this point, but I'd really like to solve the video issue for her if at all possible. Any one have any input? Thanks if you do!
Well if you would go with that route the problem would be the camera would not be good because there is no DRM fix and to install that you need to have an unlocked bootloader while for concept if I am not mistaken you don't need to and you do have DRM fixes,try reinstalling Concept to fix the camera issues
