[Q] Camera Bug - Nexus S Q&A, Help & Troubleshooting

I've been having problems with my back camera.. It can take pictures but randomly only shows a black preview of the picture taken and says "no thumbnail" for that picture or half of the picture shows gray or green colors only and also sometimes force closes.. Front camera works fine and I've already tried different camera apps and different roms but still facing this problem.. I've got no problems using video recording though that's why I think this is really weird..
Hope someone could help me out on this since I've got such an unreliable camera that is randomly usable for taking pictures which is really annoying..

I had same problem when I was on ICS but with front camera. I flashed JB and now it's not even showing black screen, it just crashes

I finally found out what is triggering my camera not to work properly.. When the device heats up that's when the back camera has issues (maybe since it is located on the upper part of the phone and that's where the phone usually heats up)..
Does anyone have an idea if this is hardware or software related?

[Q] Camera clicking/ticking noise

hi guys,
I started to get this clicking sound from camera yesterday while closing and opening camera app. I never noticed this clicking/ticking sound before. I restarted my phone, took battery out and its still there. Sometimes its louder that i can even notice while holding my phone. Its not coming out from speaker and i checked all settings. Its mechanical and coming out from camera. I have no problem using camera. Everything else working fine. i am on stock rom never rooted. I was wondering if you guys ever noticed this on your phone. I searched on google but didnt find anyone with a same problem on Inspire 4g. Thanks in advance.
No noise on mine. ClearDroid.

It's the lens moving to focus the image for the picture. Mine is noticeable too.

720p recording is jumpy. Select 480 and your results will be much better.

This is the most well known bug of ICS and jb ROMs...it has nothing to do with the camera app itself...its something with the drivers/memory
So there is nothing you can do...except going back to GB :/

So the infuse needs a new camera driver? Or possibly better memory allocation?
I might have this slightly wrong because I'm not able to access my notes at the moment but the problem is this:
Our camera (and most others) works by generating, dumping, then starting a preview again. When it records (after the restarted preview), it should enqueue "empty" buffers that should then be written to (as it records). That written data is released through the codec, allowing the buffer to be released from the queue so it can then be enqueued again to be written to (it's the circle of life, camera-style!). This has to happen quickly enough for "clean" buffers to reenter the queue, but for some reason that doesn't happen. Instead, the function that should be removing buffers from the queue is failing. Finding out why this is happening is extremely difficult because there are so many places that could be failing. Samsung have given us bum code (or none in the case of the camera hal) - or, to be precise, they've given us generic Linux drivers, that don't always reflect customizations they've made. I suspect that the problem is partly in the codecs and partly in the construction of the camera hal.
Anyone who knows about this, when I was looking over the manufacturer's sheet for what I think is our camera, it looked like the problem might be in the implementation of fimc_v4l2_reqbufs in the camera hal. According to that sheet, there is a relation between that and fimc_v4l2_dqbuf that, if improperly implemented, would cause fimc_v4l2_dqbuf to fail.
THANKS! for the in depth analysis. I think I can help narrow this problem down. After reading this I think that problem may lie with the initial buffering portion. But I think that i'm assuming this prematurely. First i'm assuming that recording only applies to video and not snapshots (Camera doesn't seem to flicker when only taking pictures, even at high resolution). Second i'm assuming that camera features and filters will require an extra amount of buffering to work correctly (not only is 720p a problem, but different snapshot scenery effects don't work at all).
Another thing i noticed is that 720p recording flickering is proportion to the amount of light you have. A dim room records video at 720p with little to no flickering while a very bright lit room flickers like crazy. Snapping pictures in any light works fine with the exception of camera features.
Light sensors are part of the recording apparatus (part of the camera) and 720p requires higher light sensitivity so...
Increasing the buffers doesn't really make a difference. I made some experimental builds to test. The prob is in the flow of data. Somewhere there's a blockage.

[Q] Front facing camera issue

Hey,
So I cracked my screen, changed it with OEM new parts, and worked great for weeks after the installation.
Now, I'm having camera issues, back camera works fine, but when you switch to front facing camera the app freezes and crashes, and I get cant connect to camera black screen, and at this point the back camera wont work either, if you restart and clear data on camera app the back camera works again, but front facing will never work. Currently, I;m running stock rooted but I've had this issue with rooted custom roms and stock unrooted. I'm not sure if this is related to the screen change or not, but it worked great for weeks after the screen change. and, I;m having the same issue with other camera apps too, no snap chat installed nor any other apps that could conflict.
Any help would be greatly appreciated
Thanks!
I am currently dealing with a similar situation. Did you find anything to help fix the problem?
This is almost certainly due a little piece of tape coming off of the ribbon cable. I happened to solve this by cutting a small piece of scotch tape and wrapping it around the ribbon cable so that the underside of the cable is not making contact with the PCB.
I know this is a super late reply but I hope it can help someone in a similar situation!
Hello. So i had the exact same problem as OP. Got my screen replaced (not by me), but a few days after that i noticed that my camera would freeze when trying to change it to the front facing camera. i had issues with messenger and the normal app. i did a few system restores and even unlcoked and installed custom rooted Roms last night. Still freezing on the front camera.
I'm now positive its a hardware connection issue. Anyone else have this issue? I feel i should open the phone and try to fix it.

Pixel 2 Camera ERROR

Hello everybody.
Had been dealing with camera faulty error message. Did 200 picture a day ago, and in the morning, my camera did not want to focus on a far object but did focus on the close ones.
The selfie camera worked OK.
After a day of unknown. the back main camera stop working fully. Just a black screen and saying faulty error. After the day it just stops working and always says the camera had closed want to send an error report.
After that, even the selfie camera had stopped working, so I got no camera, Tried everything, even went from 8.1 to Android P. But nothing.
Talk to Google, and they said that it is known issue and will replace my phone, But due to not having one single paper for the phone. (long story) Can not get the warranty.
So my only solution is to fix it my self. I bought the new camera for PIXEL 2. and Today I got it.
I removed the screen, when via JerryRIGEverythning. And did the change.
But my luck, the replacement camera is malfunctioning and it is just going left and right. So I'm stuck until I get a new one. The company already sent me a new one.
But now my selfie is working again, but my main camera is working bearly.
For the guys that have the same issue, It appears that all we need is a new camera. The phone then works.
I bought:
-camera 37 eur
-adhesive for waterproof LCD 5 eur

Pop up camera weird behavior

I had a strange behavior a while ago.
I was riding my bike, the phone was in the pocket and I got a video call for which the front cam would have popped up. When I stopped to check, the camera was partially hanging out.
Started the cam app and switched cams to see if the cam goes up and down, it didn't respond. Then I pushed the cam inside and upon switching to front cam, it won't pop up.
Rebooting the phone fixed the issue. Btw I'm on Havoc 7/29 build.
I'm not sure if the behavior is same on oos as well since I haven't used it long to experience this.
Has someone experienced the same? Is it rom specific or is this a design fault from OnePlus that'd be seen even on the stock oos?

This would be a problem with custom rom, I have never seen this issue on stock rom
