Cannot connect to the camera - ONE Q&A, Help & Troubleshooting

Hello everyone,
I've got a very annoying problem on my oneplus one (CM 12.1 RC). Every time I'm trying to launch the camera, a message tells me "cannot connect to the camera" ("impossible d'établir une connexion avec la caméra" in french).
I cannot actually use the camera, either back or front, in any of my apps using it, not even Messenger or Skype.
It used to work fine on my previous ROM, it also worked fine on this one first, it worked fine with the app ColorOS, until recently. The changes since this time are that I flashed HAL (CM_HAL_MOD.zip), and I installed lots of plugins for colorOS.
I have no idea if it comes from any of those changes. However I cleared the data and cache of HAL, of the plugins, of colorOS, of the stock camera, I uninstalled all of those, tried different versions, rebooted... Still the same error.
I would be very thankful if anyone could help !

I'm just seeing that the flashlight is not working anymore :/

Up ?

Okay, no one is probably ever going to see it but I still follow up: after having tried every other option, I finally solved the issue by upgrading to cyanogenmod 13.
I still have no idea what has been the cause... At least it is nothing hardware, as a thread has made me fear!

You just messed up your system. Thats why cm13 fixed it...

[Q] [HELP] Samsung Galaxy S2(GT-I9100) wont remember settings after reboot

EDIT2: It seems that it wont remember settings either. I disable WiFi, and after reboot its back on. Same with all other settings. If I uinstall an app, its back in normal function after reboot. If I install a new app, its gone after reboot. And I cant even perform a hard reset, everything back to normal after I tried it... sick stuff!!
EDIT: Actually it seems like it wont accept new installations or something. Because now it found new updates to apps I did upgrade earlier this morning already...
Its the two latest installed apps Im missing after installing them (Swiftkey X and Dolphin Browser HD). Also now Im trying to upgrade my phone to version 4 of android, but after downloading the firmvare, it need a restart and then I have the same problem as with the apps. Its like I never downloaded the firmware, tried 3 times now and all 3 times the same happens. Anyone have similar problems with their phones??
Also noticed that last the phone reset itself it yesterday at approximately 9.04 (that was when my weather app last updated). Really wonder what can cause this? No one with any similar experiences or possible solutions?

Camera app is not working

Hello everybody
My Nexus 5 recently captured my attention as the camera is not workig anymore. I have the latest android version, not the L however, an it's unrooted. I only have retrica and instagram for taking picture as well, but they don't seem to work too due to this problem. I don't know where the problem can be originated from, but when I open the camera app it says Cannot connect to the camera. Has anyone of you exeperience it? How did you solve it?
I tried to delete the data from the app menu, stopped it, unistalled and reinstalled the updates but nothing has changed.
Thank you
Did you already try these suggestions? http://forum.xda-developers.com/google-nexus-5/help/connect-to-camera-error-upgrading-to-4-t2564457
Camera not working can be one of the frustrating things when you use a phone. As it involves hardware nothing much can be done. I use Cyanogen based phone which has not given me any problem. I would suggest to try it as it is heavily reliable.
did you try a reboot? seems so simple, but it can fix

Solution for the "Cannot connect to Camera" issue?

As my N5 was getting slower and slower, I did a factory reset but later decided to flash Resurrection Remix Pie as it seemed fast as well. That fact turned out to be true, however, after the custom ROM had been installed, the Camera wasn't working anymore (the App said "Cannot connect to Camera").
I experienced the issue with my previous N5 from time to time, after I installed a Custom ROM, the issue didn't go away anymore.
I know that in some cases, rebooting, a factory reset or checking the camera connection to the hardware helps... But the first two options didn't work out, and why should the camera connection be bad after flashing a Custom ROM. Also, I tried various camera apps but the problem remains.
Therefore, I'd like to know, if there is a software solution to this issue after almost 6 years.
Reading your post, I assume the camera NEVER worked after you flashed the ROM, right? Strange... I am on the same ROM, I have installed a GCamera 3.2 app apart from the camera app that comes with the ROM. I get occasional "can't connect to camera" errors on both, but usually a reboot fixes the issue. Try a Google Camera 3.2 apk and see if it works. If not, I guess it is a ROM issue, and maybe you should do a clean install again. Are you rooted? Because for some reason this ROM does not play well with Magisk, when they are installed together at once. I ran into some minor issues myself (see here: https://forum.xda-developers.com/showpost.php?p=79599654&postcount=686).

[EDIT] Phone completely buggy even after full reset (back to locked stock)

Hi everyone,
I noticed that yesterday and today face recognition was not working and was wondering why. I assumed the cam could be dirty so I opened the camera and switched to front cam, the app crashes immediately.
After several tries I restarted the phone and the result is the same...
Not sure if it's a software or hardware problem, can anyone help me debug?
Ok this is getting worse
I updated from Beta 18 to Beta 19 hoping it would fix the issue. After the update even the back cam wouldn't work...
So I assumed there was a software issue. I factory reset my phone and it still doesn't work...
Any ideas please/ I am desperate...

Click to expand...
Click to collapse
If it is getting worse with beta log an event with it send it to oneplus. And maybe try a older beta again or a different firmware all together. Would probably be your best bet. Just weird your having the issue and so far no one else has chimed in on it
So apparently I now have this issue:
https://forums.oneplus.com/threads/camera-not-working.771655/#post-20390562
The storage is encrypted despite the factory reset . I will try to factory reset again once I get home (travelling right now)
Not sure how to fix this issue...
I tried wiping Cache, Data and System and doing a full reinstall but I still have the same bugs that seem to come from encrypted storage... Not sure how to solve this, should I wipe storage?
I did the "Format Data" in TWRP which is supposed to format everything and remove encryption and I still have the same bugs:
-Both cam not working
-SMS not working
-Amazon not working
-Youtube not working
etc
I completely erased the phone, used MSM tool to recover it and it still has the same bugs... What's crazy is that I know it's an access issue because one time everything started working again... Until I rebooted and it stopped
I used this (https://forum.xda-developers.com/android/software/universal-dm-verity-forceencrypt-t3817389) to keep the phone uncrypted and I am still seeing the same bugs, I have no idea what to do next...
Very same scenario with mine! Any solution? I also did what u did brother.
i can confirm the same behavior as of three days ago here. downgrading to android 9 (oxygen os still) fixes the rear camera but not the front. youtube starts to behave again. this is a HUGE issue, as my phone is 90% of the time just a youtube client. oneplus support is useless and just keeps going in circles saying to reset the phone. resets and cache clears do not fix this issue.
i've got three other oneplus 7 pros in the house that don't have this issue on beta 19, but they're all the t-mobile version flashed to international. unsure if that's relevant.

Anyone got their camera bug problem on Mi Note 10 miui 12.1.3?

My Mi note 10 has recently updated to miui 12.1.3RFDMIXM (android 11), and after that I noticed that my 5x, 2x and ultrawide are freezing when switch to it. A week later, my front facing camera too got the problem when I noticed that I can't use face unlock.
Right now only the main camera and micro are fine, but im not sure will it'll also be effected in the future or not.
I never been once drop my phone before
So, I just wanna know am I the only one who got this problem or is this a bug?
I've tried restore camera settings, clean cache and data, restart multiple time. But still not fixing it.
So I would love to hear someone that have a problem like this too.
I have the same problem now. did you manage to fix it? seems like it is an isolated case.
I tried reflashed multiple versions of xaiomi.eu, stock rom, oneos and even flash my persist partion backup to no avail.
