Camera focus fail - Xiaomi Mi Max Questions & Answers

I have the mi max for a few month, suddenly, one day, I had this problem when I tried to focus on close object, the focus got stuck on the close object, and when I try to focus on some object in different distance It couldn't change and got hot.
My guess is that this is not a software fail cause I tried full wipe. I even installed a fresh stock. I also replaced the camera part but even this didn't fix the problem.
If anyone have faced this problem or have any idea it would be just great.

Front camera stopped working

Hello,
I have a strange problem with my phone. When I try to use the front camera (using any application that makes use of the camera) I get the following error: "Unknown error by ErrorCallbBack".
Even though I am not using the camera often, I know I have used it before to take photos. I haven't upgraded the ROM or made any changes recentrly, so this is very strange.
Sometimes, after a few restarts, the camera works again for a couple of times and then fails again.
I googled the problem and pretty much everyone says it's a hardware problem. I was just hoping if someone can tell me something different cause I don't have a spare phone and can't afford to be without my smartphone for days.
Thanks,
Aris

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 cannot focus at distance

I got a warranty replacement and I'm finding the camera cannot focus at distance. Up to 1 foot it focuses great, but anything farther is a mess. Even with manual focus at infinity it doesn't work.
Sad quality control?
What about with video ?
Give the lens a clean. Take a good look at it and see whether some dust got trapped on the inside. Give it a tap and see if it moves.
With the camera app closed and not in memory try clearing the camera app cache and restarting. If that does nothing try clearing the camera data too.

Same thing with video. I had read about clearing cache/data, so I tried that as well. Even tried factory reset. It seems this camera just cannot set focus at infinity. Used several other camera apps with the same result.
Same here .. Got a warranty replacement for my bricked G4 (boot loop failure) and the new phone has serious camera focus issues. Will not focus on infinity and even at short distances has grainy unfocused pics intermittently. My old G4 camera was amazing even at infinity on max 4.0 zoom super clear pics. This one not even close. Video is the same. Very disappointed. Maybe I need a new Camera module? Any advice would be helpful.
I feel like I need to see what sprint ir LG can find out but sure they will say it works fine but I know better. Arrg!
Hi there,
Did you get a solution for this problem? I have noticed the same situation, focus for close objects, macro, works amazing, but for far objects it's out of focus, I notices for stock and 3rd party apps. I've tried Google camera, Stock camera, LG G5 camera, LG V10 camera, Pro Shot, Camera FV-5, Open camera, this issue also happens for video. I start to suspect that issue it's hardware.
Any suggestions?

Rear camera/Flashlight not recognized

My rear camera suddenly stopped working. My phone didn't get any hurt in nowhere, just suddenly it stopped working. I was takin photos since 10 minutes before, I locked the phone and I noticed that Torch tile disappeared. I thought it was a bug and I didn't care anymore. The day before I noticed that even rear camera stopped working, I was trying to take a photo but the "change camera" (from front to rear) disappeared in every camera app I was using, camera apps opened by default with front camera opened. I tried to reflash ROM thinking that it was a ROM problem (even if I was using the same rom since months ago and I've never had any kind of problem), no results. Reflashing everything starting from stock firmware, no results. As a last hope, I tried to replace the rear camera by buying a new one, but the problem it's still here. Could someone that experienced the same problem, tell me where the problem could be? Or maybe some possible fixes, every kind of help is appreciated. Thanks.
Same
I have the exact same problem. After wiping the cache the rear camera is recognised and I am able to take a picture with it (which is not saved into gallery) but about 5 minutes later the option to switch to rear camera has gone and all camera apps (including social media such as snapchat) is stuck on front camera. This leads me to think it's not a hardware problem but rather that of software with which I am running cm13 nightlies that I have updated every day for the past week in the hope it will be patched.
I have this exact same problem on my d855 too..!
Sooooo frustrating, I've been looking everywhere for a fix, tried full factory reset the other day (I'm running full regular stock with no root or anything), and sadly that didn't work either... I'm glad to read someone has tried changing the camera hardware, cos that was I step I've considered taking, but I now know would be a waste of time and money...
But still, the problem persists..!

I don't think that's a software problem simply for one reason: I'm on the same rom and kernel since months and camera worked fine. It stopped working suddenly with no reason.

Yeah now you made me understand why the camera worked for some minutes. I'll try clearing cache after installing new camera module. I'll report the result. Thanks anyway.
Edit: It's not working. At first boot, systemUI doesn't load well, when I reboot everything works fine but rear camera isn't working. Maybe late I'll try with phone's camera. Now I'm using the new one bought some days ago.
same here!!!!! I'm using LOS13.1 on my d855 and i can't fix it... any idea?
What OS are you guys running? Is everyone experiencing the issue on Cm13?
Also try cleaning the camera connections really well.
I have same problem. Although i expirienced it first time on Lineage OS 14.1. Now 30B, but it still not working. I was listening to music through external speakers, and suddenly it stopped working. Music app was "playing" but i couldnt hear anything and when i exit the app my phone just stops working and starts being laggy as hell. Later that day i found out my camera is not working. I tried reattaching cam connector but it did not work...idk if i should order a new camera or it might be a software fix or something
same problem
happened to me after upgrading to 6.0 , downgraded back to 5 with no luck , even opened my phone and released and reconnected the 3 cables inside with no luck at all . don't know what to do
It's "good" to see other people with the same problem as me.
I replaced the camera and it still won't work.
I'm afraid that it might the problem with our motherboard...How can software block our camera even tho all of us fully reinstalled ROMs/Modems etc? It would be awesome if dev would see this and tell us what is the actual cause of this
If you reinstalled the entire OS using a TOT method, no files are left behind. This is more likely a hardware issue.
The Camera module is extremely close to the problematic hot chip on the G3 so it's not impossible something got messed up.
I have a d852 in Canada that doesn't get hot and I'm having this problem too. Going to order a new camera since I know this is a hardware issue. Hopefully fixed the issue. Not cool having no rear camera or flashlight
It's impossible Every G3 gets hot...you either are not heavy user or idk...but every G3 that i've held had the issue of overheating at some point...and indeed it can ruin everything...imagine 120C on your processor...that kills everything around it...idk if my processor got that hot as i've seen in some cases it did on internet, but it did go up to 90ish...and that is too damn hot
FIX ISSUE be Done
Hi all .
Problem method for repair
Issue is easy buy new rear camera D855 or this same conector D820/D821/Nexus5 is this same and all works fine I'm tested on my D855 International

If u tru turn on flashlight he said (on broke camera) " Immpossible turn on flash light when camera work" !!!!!

Need help fixing/calibrating camera focus

So... I've tried many ROMs on this phone and the one that I like is This one. However there is one problem with it and that is the fact that focus is broken and the OpenCamera app 90% of the time takes a photo that's out of focus and it takes 10 tries to finally get at least one photo that is on focus. (yes I tried many focus options in the app)
Is there any way to calibrate this or fix this somehow?
There is Another rom where this is not an issue, (but I don't like that rom due to other stuff). Maybe I can copy some files over from there to fix this? I have no idea how these works. (when using OpenCamera app on that rom, it takes photos and focuses just fine on the first try)
I just experienced this focus problem.
In logcat it's reported as
Code:
mm-camera: [CAMIF]: semc_camif_sensor_get_focus _driver_ready:semc_camif_sensor_get_focus_driver_ready failed -22
I believe this to be hardware related, since changing rom or wiping didn't seem to make any difference (even though until just a week ago there were no problems).
But every now and then, I don't know why or how, it suddenly start to work again.
One of these days I might try to change camera module with a spare one I have.
Maybe you think it's a hardware issue because pretty much every custom ROM out there for this phone has that issue. (the one I linked also has that issue, just not as badly as others)
Right now I'm running the stock rom (that comes with the phone) and I have no issues with focus.
