[Q] Camera failure on S3 (T999)

I have a problem and after trying lots of thing I am stuck and don't know how to continue.
My S3 felt from a riding bike and so the LCD was cracked and even the battery cover was lost. I refuburbished it myself and at the end the phone was working perfectly ...except for the camera.
there is an error while trying to use Galley to take pictures. After the error the Gallery closes.
In fact the camera is damaged, because I have tried it in other working phone and it does the same.
Nevertheless, if a working camera is installed in my phone it doesn't produce the error immediately. It takes a little time to fail and the camera causes a FC in the Gallery when trying to take a picture.
I've tried:
1. Load stock firmware 4.1.2
2. Load stock firmware 4.1.1
3. Load my actual CM 10.1
4. Update camera firmware to all the available versions (ZDxxxx)
5. Use 2 different working cameras
Is there somthing more upgradable or any other adjust I can do?

Rear Camera stopped focusing

I'm on CM11 nightly, which did at one point have problems with the camera. However it had been working fine for a while. I don't remember doing anything to my phone (no upgrades, drops, etc) but the camera just stopped focusing.
I've tried ALL the setting in the stock and several other camera apps.
I tried wiping.
I then installed jelly bomb which (I believe) is based on 4.1 stock.
Still won't focus.
It seems to be stuck in a macro focus, I.e. when the camera is 2 inches away from an object, the object appears in focus.
Anyone seen this or have an idea?

There is also more on this in the cm11 nightlies thread.
Sent from my SPH-L900 using xda app-developers app
Thanks for your reply. Unfortunately, that zip didn't change anything
Also, like I mentioned, I had wiped and gone back to (4.1) JellyBomb just to try the camera and it didn't focus there (eliminating 4.3/4.4 AOSP camera issues).
It had been working fine with CM11 nightlies (after the initial issues you referred to were solved).
I'll keep trying stuff, but I'm starting to fear it's a hardware issue.

Camera focus stuck on N7100

After more than 1.5 yrs of using my Note 2, recently I noticed that sometimes the camera focus gets stuck. It seems to be at macro focus distance. So everything close to the lens will be clear, and things beyond that blurred. There is no way to refocus. No matter what I do (using manual touch focus, setting to autofocus, setting to macro focus, setting to video mode, killing the camera app or restarting the phone) it is stuck for some time. And then it just starts to work again by itself after few minutes. Completely randomly it seems. I'd say it gets stuck approx every 5th time when I turn the camera on.
If I look at the lens, while the focus is stuck, the lens, naturally, also don't move as they move when the focus is not stuck.
What could this be? My bet would be an issue with camera, but I'd like to exclude any possible known issue, before I RMA it. I still have few months of warranty. Normally I would be doing the factory reset, but I was kinda waiting for the 4.3 or 4.4.2 update, and fresh flash.
I'm running stock 4.1.2 (still the latest official for me), and it is rooted, and triangled away. Everything else is stock. I use stock camera app. Also I don't seem to have any other problems. When it does focus, the camera produces sharp photos. SO no problems there either.
PS The lens are clean and undamaged, as is the whole phone.

Camera Problem in Lenovo Vibe Shot (Z90A40)

I have Lenovo Z90A40 Stock Android ROM 6.0.1 Build Number Z90A40_S363_160625_ROW
I have a big issue related to camera, it works fine in indoor or at distance of around 4/5 Normal Rooms
But when I go out door where there is more distance such as in mountains or a big park, then camera stucks at
autofocus and a few 2nds later phone restarts, after searching I tried to reflash ROM / reset device
but all goes in vain, it has a good 16 MP camera but I effectively cannot use it where it is most needed
No error message is ever shown during this problem or even after restart
In outdoor, if I hold phone very still in my hands, then the problem does not arrise, it only arrises when
I normally shake the phone, just like a normal person would do to take a nice picture
I am a rooted user with Xposed framework installed
I tried other Camera apps from Play Store assuming the issue is with Stock camera app, but I think
the issue is related to camera hardware with autofocus in vast areas
So I was looking for a solution, Can I handle this restart as in: Can I skip this restart, is there any normal
or Xposed application that can help me in this regard or any other trick
Plz help

Video Calling or Camera system issues on Mi 9 SE on MIUI 11

Dear All,
I recently upgraded to MIUI 11 and there are numerous problems, some of them as follows below
Video calling using Google DUO is problem the front cam is very unstable and the application itself crashes very often.
mic usage during video calling is worst, opposite ppl cannot hear anything no matter how every you hold the phone and while taking portrait mode shots via back cam, it does not settle VF keeps changing and post 2 or 3 shots app crashes.
Need to know if anyone else is having this problem and is the issue with MIUI ? or Hardware?
