[Q] Issue with apps that access the front-facing camera

About 7 days ago, my camera app started force closing everytime I tried to open it. Thought it was an issue with the CM10 build I was using, so I wiped and flashed the official AOKP ROM. The issue persisted. Tried multiple ROMs, including stock. It seems to be an issue with not only the stock camera, but with any app that accesses the front facing camera. Skype won't let you log in. The stock camera app force closes. Camera ZOOM app works with the rear facing camera, but won't let you use the front facing camera (just flashes black when you try to switch to the front camera, then switches back to the rear camera). This all started about 7 or 8 days ago, and I initially thought it was an issue with the experimental version of CyanogenMod 10 that I was using. But after multiple wipes and reflashes, that doesn't seem to be the case.
Anyone else experiencing this?

Sounds like a hardware issue. Maybe you can get the hardware to reset by leaving the battery out for 15-20 mins?
Swype'ed on my CM10 Galaxy Nexus

go back to stock and see if that resolved the problem.

Let the battery sit out for an hour today at work just in case, no dice. Clearing data/cache in the Apps menu, no dice.

Yup, tried that. Did a complete wipe of internal storage, not just user data. Used the GNex Toolkit to put stock 4.0.4 and 4.1.1. Same results with both. I've (miraculously) never dropped this phone, so I'm not sure what could have caused the front-facing camera to fail. Either way, Verizon is sending me a new one. Drives me NUTS not knowing what really went wrong though.

[D855] "Cannot connect to Camera"

I don't know what's happened, seemingly over night my camera no longer works. I was running Cloudy 2.5 and I wiped it and installed CM12, still no luck. Now I've got it running PA and STILL the camera refuses to work in any apps. I installed FV-5 camera and it just crashes when I launches it. Snapchat tells me to restart the phone but after a few attemps, I can get the front camera to work. I'm starting to think this is a hardware problem as I've flashed new ROMS etc. Has anyone else had a problem like this?
edit: I just installed and launched Snapchat again and when I switched from the front camera to the back, it worked for half a second and then froze. Restarted the app and now it seems to be working.

I had this issue on my g2 all roms nogo so i flashed back stock kdz and it worked then flashed all same romsa again and it actually work so im asuming it was some stupid issue from the factory. But mine done it from the start on stock rom i thought it was a hardware issue it was a warantie replacement i didnt know i had the pbone for about a week and went to take a pic and bam so like i said i tried many roms nogo a fresh new tot

I'll give it a go because it still seems broken. It's working sometimes, but in snap chat the image is flipped upside down and there's a purple tint. Exiting the app and opening it again fixes it, but most of the time it's not working.

This happened to me, but on a different device - it's a CM bug. You could download an app called "restart camera" by temasek from playstore to see if it helps.

Mine was on a ls980 sprint g2 and a stock. And stock based roms never tried cm really

I have LG G3 *D855*... My phone worked fine and fast 2 and half years, no problem, warranty after 2 years was over, but I even didnt think about other phone, because I realy like LG G3 and there is nothing very better created yet + I used mobile case and phone is in perfect condition. Ok, after 2,5 years, phone never was swiped, it was overloaded with files, photos, apps... One day, camera start crashing and sometimes I got some lagz. I decided to root the phone, installed Cloudy 3G, camera worked only first 10mins, then crashed like in stock version. I found one flashable file, called camera fix lgg3... It fixed camera, no lagz on camera, no problem with crashing, flashlight worked, everything was fine. But damn, that Cloudy3G was so unstabble, sometimes phone freezed for a while, sometimes it restarted itself, sometimes apps crashed, like facebook, whatsup and other... But... The biggest deal was with battery... Battery drain was awfully high... If phone was in standby mode, battery taked only one day, but... If I used any app or just watched videos on youtube, I was able to see how % was dropping in minutes. It was like 1 min = 1-2% gone. So, I flashed CM14... Nice mod, I liked, takked few hours to know the mode and customize it for my needs. Camera worked first day, then crashed again... Actualy... It worked sometimes, like 1 time from 10 attempts with phone restart. But, for short time, sometimes 1min, sometimes 30mins. I didnt find any fix, cause that first fix was only for stock camera version... Decided to flash other rom... Fulmics was next, worked fine, mode is cool, stable, battery life is very good, almost like stock version. Camera worked for 2 days, then the same problem... Cannot connect to camera or camera is busy...
From starting, I was able to get into camera by restarting phone, but after few days, no restarts helped.
What I can do now? Any suggestions? Ohh, and sometimes camera is purple and shows upsidedown, before crashing.
All, what I can imagine to do, is try another ROM or try to swipe everything and get back to original stock version. But its not so difficult like installing custom roms. So, it will help or somebody has other solution?

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

Camera won't focus on foreground, except in the actual "camera" app

Alright, this is starting to drive me crazy, it follows me to every ROM I try.
The camera...it just sucks. I'm currently on ExperienceOS, and loving it, but I've had this issue on FreedomOS, Lineage, Resurrection Remix, and OwnROM. Anything other than the default "camera" app, just plain can't use the camera. It's terrible. Snapchat, mobile check deposits in my banking app, scanning apps, really anything that uses the camera except, again, the actual camera app on the phone, has awful quality. It'll focus the background, and everything in the background is crystal clear...but no matter what I do (angling, tap to focus, pulling phone back and pushing it closer to try and re-focus it), my phone will NOT focus on the foreground.
I can't be the only person having this issue, and I really don't think it's a hardware issue. I think it's probably something more to do with firmware, although I am on the latest firmware and have flashed back to stock OOS before coming back to ExperienceOS.
Does anyone have any ideas or suggestions? It's making this phone not fun to use. I went back to my Nexus 6P for a bit, until it died at 24% battery, reminding me why I switched away from it. This camera bug is literally the only issue/complaint I have about this phone. Please help...
P.S. - Rooted using Magisk, flashed ElementalX kernel (I've tried sticking with the stock kernel, and using other kernels, so I don't think it's a kernel problem), and I've tested it with many different apps that use the camera...everything but the camera app is fine.

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.
