mm-qcamera-daemon on 4.4.4

I had this on 4.4.2 but 4.4.3 fixed it. I'm on 4.4.4 now and have been since it came out, but all of a sudden last week, mm-qcamera-daemon came back and I'm not alone.
With L just around the corner, I doubt there will be any fix for this from Google, so what's the best way of finding out which app is keeping this service alive?
P.S. I have neither Skype, Instagram, nor Snapchat installed - and never have done - so it's not them.

Did you have a camera app running in the background? ie. minimized it without swiping it away.

Nah, nothing like that. I'll even get it when I boot my phone, open no apps at all, and charge to 100% before unplugging from the charger - this action seems to be the cause of the daemon, like some of the other users on that issue report are saying. Never mind, I guess I'll just wait it out until L.

I have never had this problem on my nexus 5 until today (I bought the Nexus 5 on day one)!
This process is draining all my battery!!
The only app I installed in the past week is "Google Opinion Rewards" which was installed 6 hours ago.
Please help if you find a solution
UPDATE 1: I just noticed, via CPU-Z, that all 4 cores are continuously active at high frequency and the phone is overheating
UPDATE 2: Problem is still there even after removing "Google Opinion Rewards"

Just reflash the stock firmware and see if it continues.
Best thing to do with any issue that a solution can't be found for easily. ?

the camera daemon is supposed to appear. its not supposed to stay around, draining battery. especially at 100%, you will see it, as the phone uses it a little bit, and you havent used the phone at all. it will show up. the question is, if you dont use the camera at all, and it appears in your battery stats, after a full cycle of use, how much battery does it take? chances are that by the end of your battery cycle, it wont even be in your battery stats.

I actually fixed it now by flashing the system image and restoring all my apps via Titanium Backup, but I swear I'd never even open Camera for it to occur, and I don't have any third party camera apps. It would constantly be active without opening any camera apps at all.
edit- also Google have restated that they're looking into this bug and have marked it urgent, so anyone else getting it - don't panic too much, it's most likely not a problem you've caused.

I suspect the Hangouts/Hangouts dialer. I updated the app few days ago (no other installs), today was the first time that I got this issue (got my Nexus in February). Also first time since updating I used the camera, followed by battery drain/ daemon/ "failed to connect camera" etc.

I think its because of android wear
With android wear u can access the camera, hence u will be seeing the camera drain for sure. i unpaired my watch for few days and i didnt have this problem till now

I had this problema today morning, my android version is 4.4.4, In my case I used yesterday the camera to attach a photo inside the facebook messenger, maybe this buggy app make this mess in my case.
I reboot and waiting for the results

Same here
Everything was ok from 4.4.2 till 4.4.4. But suddenly week ago discovered mm-qcamera-daemon issue, tried many things without success. I am using phone in safe mode (facepalm).
Waiting official Android L or fix from google.

I got the same issue now!
Started today, what the hell?

Some apps will keep the camera wakelocks going. Freeze anything that can possibly use the camera and see what happens.
Or just clean flash stock, and see if its OK. If so... Install a handful of apps per day.... Then if it goes nuts you know it's an app you've just installed.

https://code.google.com/p/android/issues/detail?id=70755#c171

I think i had this fixed. Ihave a rooted nexus 5 stock rom. Installed greenify, pirchased the donate version and had the camera app greenified. No more mm-qcamera-daemon showing up on my battery stats. No more "cannot connect to camera" issues. (So far it's been 2days without it.

camera block app
i see this issue occurs when i use skype or any camera related app in my grand 2 4.4.2 / only way i keep the issue at bay is use camera block app.. which i keep it turned on when i am not really using the camera.
this seem to keep this daemon under control and not drain my battery .

freezes and reboots (Note edge G)

Hi everyone, few days ago i got some problems with my phone.
When i am doing smth, for example chatting in whatsapp(it can be any app, even the menu) , the screen may freeze from 5 to 20 sec. After it, the device may become locked or not. Also, after it, device may reboot. Or just shutdown.
I already tried :
1 wipes (full via phone menu and recovery)
2 formatting flash via custom recovery
3 flashing 5.1 via odin
4 emergency restore via Smart Switch
But the problem is still here.
Is this a hardware problem, or should i try smth else?
Thanx for advice

I'm starting to wonder about hardware issues myself.
I'm getting the feeling that Samsung wound the processor too tight on these phones.
Once I get rooted again,I'm planning a proc' downclock to 2.3/2.4 Ghz.
I'm not totally sure,but if these proc's control the RAM directly,that might help with stabilty issues.

Just to confirm; you did a factory restore and also flashed the stock 5.1.1 for your model and region with Odin 3.10.7?
Sent from my SM-N915G using Tapatalk

yes, exactly. Not sure with odin version, but everything was fine.
Yesterday also tried River rom with Mickey Kernel. First few hours phone worked normally, but was a little bit slow (it is normal for this kernel). But then the problem returned, i got some (2 or 3 ) reboots and lots of freezes.

weird. I started gettig these issues a couple of weeks ago too. Did as you did, Odin, Smart Switch, TWRP. Nothing. On RiverRom it seems to be more stable than on the official Rom. Which is crazy. Searched through all the logs, only idea i got left is keeping in under android logcat on my computer until it crashes.
Also phone won't restart if I want to do that. Not from menu, not from TWRP. It will just not do it. It shuts down and no matter how much I press the power button.... nothing. Hve to take out the battery, wait 30 seconds, plug it back in, and it will start.
Any advices on what logs should be looking at would be much appreciated.

I just tried to restart my, it booted normally.
Maybe its overheating or smth like this? It will be difficult to demonstrate this problem in service centre

honestly i don't think it's overheating. For me the behavior is a bit weirder, as said, as the phone won't restart, unless removing the battery and waiting for a minute or two before plugging it back in. Every. Single. Time. Not even rebooting from recovery.
I use now riverrom with the emotion kernel (they launched this year a new version of the kernel) and it seems to be better. Weirdly enough, the system gets slower when i turn on GPS (although i have next to nothing appls installed), and the apps that say they stopped responding are the boring ones. System UI, Google Play, etc. Also downloading the kernel auditor from the guys at emotion and enabling logcat seems to help too.
An error i seem to get constantly now is google play services error.
Bluetooth also seems to be an issue, i also have a android watch and it gets kinda weird behavior.

Why does my Google Pixel randomly reboot?

Hi. My device worked just perfect until 5 days ago. It slowly began to ignore some tasks like opening apps or doing calls.
2 days ago my google pixel with Android 8.0 started to ignore every input i made, like opening apps or trying to reboot. It behaving like this after taking some pictures with the rear cam. After some attepts in opening apps it started to reboot. But instead of a normal reboot it stuck in a booting screen (the one with the Google G and a gray animation bar underneath). It took a while and i waited until it seemed that the OS booted correctly. But after this my device started to reboot randomly after a few minutes. After a while i figured out, that i can hold the power button while the screen with the google G was up to reboot it normally. This worked so that the phone was at least half an hour or more working until it rebooted again out of nowhere.
So far i tried to get it in safe mode and delete some apps like whatts app etc. In safe mode i didnt notice any crashes so far.... but in normal one it does a lot so deleting apps wasnt helpful. Turning on flight mode was not helpful either.
What can I do? What could it be?

Same thing happens with my Pixel, sometimes the phone is just get stuck on some random screen then I have to press and hold it for 15 seconds to let it reboot again. Lately I have started to see another problem, when it reboots bunch of google apps and services stops working and gives hell lot of notifications. All this started to happen after Android Oreo update

I noticed problems with my ear speaker as well. And i cant make phone calls. The phone doent respond anymore when i try to.

Same problem after android 8.0 update

If you have installed the latest Google phone/dialer app, that is likely the problem, was for me.
Find the app in settings and uninstall,it will roll back to a previous version and hopefully fix your issues.
Sent from my Pixel using Tapatalk

My pixel does the same thing, ever since I updated to 8.0, have you tried doing a factory reset? I haven't done it yet, I have been uninstalling apps for the last couple of days, when it is in safe mode it works good, but when it's not, it freezes and restarts. I'm going to try uninstalling the latest version on google dialer to see if it helps.

I just want to update everyone in case you are having a problem with the random reboots.
I uninstalled the phone update and it was still randomly rebooting so I backed up the stuff that I needed and just did a factory reset. I have been a full day on my phone without any problems. I did a factory reset twice, just in case, for some crazy reason, the phone still had a problem, I wiped it twice! I think you'll be good with only wiping once.
Anyways to sum it all up, I did a factory reset, restored all of my backed up data from my pixel, I had about 120 apps and the phone has not had a problem since. I hope it helps someone else.

Mate, please report if you're still getting the reboots. Mine disappear for two weeks after I do a factory reset and then come back. Same happens in Safe Mode. Bug report claims it's 'Sense Key : Hardware Error [current]' and Google rep says it's a hardware issue (Toshiba's memory or something). Buganiser thread is here.

wrong place sry

Had this on my pixel xl. I was on the 8.1 beta.
factory reset, rolled back to 8.0
8.1 ota official
haven't had a reboot in over a week now

Yea, the issue is back, has been for about 2 weeks. This phone is really starting to be a pain in the ass, I can't believe that it happens so often. Did you do a warranty fix?

That's a pity. Yes, I did. Got the device roughly two and a half weeks ago. Flashed 8.0 and then sideloaded 8.1 right away. Knock on wood, all good. But there's still a report every other day in Buganiser of a phone even on 8.1 doing this.

Got mine at release. November 16. Google won't replace it either. I have a one pixel brick

I have the same problem. However, it is not frequent enough on Android P beta. But as soon as I go back to the stable build, it starts to do the same thing. Did you guys have any luck resolving this or should I send it back to the vendor I bought it from. They won't replace the device in Pakistan but may be will fix it in some manner.

SM-G920F constantly slow and hot

Hi everyone, recently I had some troubles with my Galaxy S6 ...
The problem is that the phone gets really hot even when I'm not using it and when and the system in general in really really slow... So, I decided to install BetterBatteryStats in order to better understand if any Kernel Wakelock was causing the problem and YES !
There's a so called "flip wake lock" that is active almost anytime and when it does stop (it stops automatically sometimes) the phone comes back to life, fast and smooth.
So, I was wondering if any of you has ever heard of this wakelock... I , of course , already searched in Google but pretty much no one knows what this is about...
Also, I had to manually disable the softkeys because the were constantly fading in and out.
The touchscreen is fine because when I'm in recovery mode everything is smooth as butter and YES, I have already tried a wipe data, I changed rom, I did format all my data and went back to a stock rom, I changed Android Version but nothing seemed to work.
Thanks in advance for your help, have a lovely night.

I would advice a full wipe and re-flash Stock Firmware via Odin.

If a magnetic case is installed, remove it and see if the wakelock persists. If there are magnets around the phone, remove those and see if the wakelock persists. Also worth checking is the 'USSD' code hwmoduletest *#0*#, select hall. If the problem persists try to disable the hall sensor in the kernel.

Phone freezes up

Has anyone experienced your U11+ freezing up.
It has happened to me about 3 times.
It generally happens over night while it's charging. I get up one of those mornings and the green light is on, remove the charging cable and I can't wake up the phone. I can't even turn off the phone by pressing and holding the power button to kill the device. The only way is to put it into download mode by simultaneously holding down the vol down key and power key, and then when the menu comes up to select the reboot option to get the phone back to normal.
Has anyone else experienced this or know what could be causing this to happen?
The problem is that I use my phone as my alarm clock, and when it freezes up, my alarm doesn't work.
Any suggestions anyone?

No problem like that until now.
However, noticed sometimes that the my alarm, which is setup for vibration only, only vibrates once and then continues silently alarming until I turn it off.
Happens randomly but still strange. I've to try with another clock app.

That's really odd.
I'm going to turn off the always - on feature and see if I get anymore freezes. I had another one this afternoon.
I'll report back after some time and let you know if there has been no more freezes.

I'm just updating to the latest update 1.23.709.3 and see also how it performs.
I'm a bit concerned about this random freezing that I have experienced since I got this device.
If it persists I may ask for a new one.

I'm still on the October security patch so I'm expecting one for the December period soon I hope.
In regards to your freezes I've not encountered anything like that so far been working flawlessly so far if there is anything I can test let me know

I have the Taiwan version.
If you could try the always-on feature for a couple of days and nights and report back, that would be awesome. However, I selected the option, for always-on to only come on when I moved the phone. (good for night time use especially)
I had my phone in the pocket yesterday afternoon and it froze.
As I stated earlier, I can only restart the phone only by putting it into download mode and reboot from there.

Thanks for letting me know.
I guess I can rule that feature out as a probable cause.
It must be some other app that's causing this issue. But it's a pain to go through the process of finding out which one.

Yeah trial and error isn't fun. I'd probably factory reset though and see if it happens with barely any third party apps installed.

I have the HK model I think and I had the AOD when I first got it, set to motion and nothing has happened to my phone in regards to freezing fingers crossed. I have disabled it for the moment as I noticed a greater battery usage overall, I believe between 9-10% overnight and only 2% when I had it disabled.
Hopefully you find the problem otherwise see if you can get it replaced...

Since not using the always-on feature, I don't have any more freezes. Must be some conflict with the alarms and always-on. Can't see what else could be causing those freeze ups.

My phone surprisingly just froze up yesterday. But at least it's been a long while since not having the always-on feature enabled. With always-on enabled, it seems to have happened every day.
The issue I have most about this, is missing that important call when I haven't realised that the phone is frozen, because sometimes I don't pick up the phone for hours.

I had to do a complete fresh install from scratch and I have no more issues. I believe all my issues came from using HTC's transfer tool when going from u11 to u11+. Importing all the settings features using the Transfer Tool has caused issues. I'll never use this tool again.
All good now.
