Nexus 5 camera

But 'mm-qcamera-daemon' glitch may affect other KitKat devices too

Google says it has fixes ready for reported high CPU usage connected to the Nexus 5's camera, according to a post by a Googler on the company's issue tracker. The bug can cause the phone's CPU to become maxed out — resulting in battery drain — when using the camera, with "mm-qcamera-daemon" showing high battery consumption in Android's power consumption display. As the bug is related to the process handling camera data, third-party apps may trigger the glitch as well. According to the update on the Android issue tracker, Skype in particular "seems to access the camera regularly from its background service in some way that triggers this bug," though the poster says they don't believe this is a bug in Skype itself.

The Google employee says the bug will be fixed in the next maintenance release of Android, but until then the only remedy is to reboot the phone. Uninstalling Skype may also fix instances where the app triggers the "mm-qcamera-daemon" in the background. Perhaps more worryingly, though, the bug can affect other KitKat devices using Qualcomm chips for camera processing, such as the Galaxy Note 3. For these devices, the Googler says owners will need to wait for the device manufacturer to issue their own patch.

Meanwhile Nexus 5 owners should expect the fix along with other improvements in the next update, most likely Android 4.4.3.

Google pinpoints Nexus 5 camera/CPU usage bug, fix coming in next Android release

For now my temporary fix is downloading an app called "disable camera device ics" which stops apps from accessing the camera.

No wonder my Note 3 has been draining lately. It's been a different app lately using way to much battery when I'm not even using it. Ever since KitKat Google has had a lot of issues with their sources and internals.

On the Nexus they have. That is why we 4.4.1, 4.4.2 now 4.4.3

-------------------------------------------
You really should see the crap I don't post. Sorry if honesty offends you

So? iOS is up to 7.0.6. Does the need to release 6 point releases suggest they've had twice as many problems as Google has with their latest milestone release?

My point is that the first two kit Kat minor releases were mostly to fix n5 issues

-------------------------------------------
You really should see the crap I don't post. Sorry if honesty offends you

and the first two 4.2 minor releases(4.2.1-> December Bug, 4.2.2->BT Audio Bug) were mostly fixing Nexus issues as well,This is nothing new. The first two Jelly Bean minor releases(4.1.1->Nexus 7 screen orientation bug, 4.1.2-> more lockscreen/home screen rotation support & bug fixes for N7) are the same.

Android minor versions have always been mainly bug fix focused, what you observed with KitKat is nothing new at all.

Yes. It's not like you can't easily see online which issues triggered each of those 6 points. Several were quite serious.

So then basically it hasn't had any more issues than any release of any OS ever before? So the comment was irrelevant? Thanks.

The Nexus 5 has average battery life? Mine is excellent, although I am coming from a gnex which was terrible even with extended battery.

I bought a Nexus 5 the other day, love it but battery garbage. Just thought I'd share even if off topic.

Getting full day 12-16 hours and 5 hours of screen time on my N5 (heavy user, all syncs on, location reporting, wifi scanning, google now, on WiFI mostly with some LTE)

I can provide you screenshots of over 7hrs SOT on a Nexus 5...granted that's trying. 4-5hrs SOT is NO PROBLEM syncing everything, high accuracy on, data and wifi on (not scanning though) with stock+Xposed/GB and most importantly Franco kernel. That said I was using my camera/recorder a lot this past weekend at a wedding and had to bust out my battery pack, so this update is welcomed nonetheless (as always). Thanks big G.

I have a whole forum thread dedicated to this with multiple screenshots of the same 5hr screen time and 15 hour day. People think its impossible but its not. And like others say, that's with heavy usage. Art runtime seems to be a major player in that for me too.

Finally they are fixing this problem...…that I knew absolutely nothing about haha...good stuff Google keep up the good work ;)

I often wonder if the Nexus cameras are all gimped slightly on purpose to stop them being a total blitzkrieg on the top end Android Market.

"Well the Nexus is a great phone for the money and its got great specs ...but...you know...the camera isn't all that great!"

It's like there has to be at least one big negative with going Nexus.

I'm a N4 owner just in case.

I doubt it, since the Nexus 5 camera is actually better than most reviewers will admit. Sure, it has certain conditions where it shines the most, but so do all cameras. I have taken over 600 pictures since I got mine the first of January, and nearly all of those pictures are very high quality shots without major noise, blur, or washed out color. Can the camera on it be improved? Certainly; however, it still beats the camera in most mid range phones, and is surprisingly good for a $350 phone.

But that still isn't saying much. Notice the two phones closest to stock, have cameras that suck?

Why even bother coming to a nexus post we get it you hate nexus devices get over it and move on.

Posted via Android Central App

I do not hate the n5, but every time I talk about issues with stock, people tell me I am full of it.

But, if you would have read the article you would see this isn't just a single device issue

-------------------------------------------

Its a phone camera people! I know it's not the best, but if you want some professional grade photos, go get a DSLR! A phone's primary function is to communicate! The pictures aren't the best, but who cares? The end of the day, someone who bought the Nexus 5 saved a lot of money and got a good phone.

Nexus 5...enough said

But why settle? I took some incredible shots at a Mardi Gras event last weekend and didn't have to lug around an extra piece of equipment on a pub crawl

-------------------------------------------

I wouldn't call it settling. Your paying more money for a phone, subsidized or not. For a sub-500 dollar phone, I'm not complaining at all that the camera isn't on the top of the charts. Getting a phone that costs 600-700 dollars, that better take good pics! Don't get me wrong, Samsung and other flagship's take really nice pics! But just a little too expensive. Besides, the Nexus 5 is a solid phone all around, not to mention it gets the latest flavors of android the fastest!

Nexus 5...enough said

The N4 was a huge upgrade to the Gnex, the N5 is a huge upgrade to the N4 regarding the camera. It's not thee best, but I promise you out of 500 shots it'll take just as many great ones as just about any flagship phone out there. Plenty of video reviews has it besting the iphone 5s...generally touted as better than any Android camera by professional (or paid lol) reviewers.

I settle (and despite what people say above, it definitely is settling) because the camera isn't a huge deal to me. When I bought the N5, I was considering an unlocked One instead. If I were more interested in photography, I would've gone with the One in a heartbeat. As it is, the $250 or so that I saved was well worth it.

I had this problem, the device got extremely hot as well. I uninstalled most of my camera triggering apps, but this did not resolve the problem. So I did factory reset and was very cautios while installing new apps. Since then, I haven't noticed the bug at all. But a fix is necessary because it became quite annoying.

Well at least Nexus 5 owners won't have to wait for carrier approval for the update. Unfortunate for other devices on KitKat although carriers have gotten with the speed of releases.

Well I don't find others unfortunate. They took the decision to buy a non-Nexus. If they expect timely updates, then they failed at choosing the right phone for them.

I think you guys forgot about custom ROMs. Even if you don't buy a Nexus, you can still get AOSP experience which will get this fix sooner than going through custom ROM.

No sir, "we" have and/or have had non AOSP devices running AOSP custom roms. It's an option and a good one for many, but it is actually pretty far from "the same."

Lol

Then you're just not trying hard enough.

Either that or you got the special N5 that doesn't have this issue.

Either that or you're just lucky.

Haven't seen this yet; of course have only had the phone about a couple weeks. Don't use Skype/Snapchat so maybe that's why I've avoided it so far. Hopefully the fix pushes soon as this is a nasty bug.

This has happened to my N5 twice. I notice unusually high battery drain and sure enough, mm-qcamera is using a huge percentage of the battery. Rebooting solves it. Glad a fix is coming.

This is not just a kit kat issue. I've seen this twice on my Note 3, and it's not running kit kat, (Verizon)

I noticed this sort of bug on my Galaxy Note 3 way back in 4.3. I simply uninstalled the Yahoo Video and Audio plugin and the problem went away

I haven't noticed this being an issue on my Nexus 5, but I am still having the "calls dropping" issue. I have not seen anything posted about that, despite the numerous forum entries all over about it. That seems like something that would be of major interest to have resolved. It doesn't seem to be specific to a network. While off topic, anytime Nexus 5 has a posting, it's valid to describe the issue, in my opinion. When the mobile network is set to LTE (preferred), the signal seems to cycle from nil to what's available several times, until the call just drops. If it's set to 3G, I have no problems, except that I don't take advantage of LTE speeds. This is an issue.

While in the store (tmo) I noticed that n5 had the highest dB among other flagships on dusplayOver 10

* 10 over mine.
If you are commuting in the low signal area 5-10 dB can make a big difference.

I've never experienced or heard of what you're talking about, but you should know that you can't make or take calls over LTE yet (VoLTE). So in an LTE area when you make or receive a call the radio switches to HSPA/CDMA etc. Sounds like you may have an isolated hardware/radio issue or it is indeed a carrier issue. I'd start with flashing a different baseband or doing a factory reset.

I hate dealing with that switch from LTE to CDMA ! While on the road as soon as I drop to 3g (CDMA) unless I reset the network search (airplane mode on n off) I would get stuck on it for longer.
That switch def drops calls, so if this N5 is on Sprint that might be the issue.

You can do that now

I've seen this bug a few times but the Google Play Services bug is killing my battery more than anything since the last update. It keeps my phone in a constant wake lock, where as before the last update, screen on and awake where nearly identical.

"...the bug can affect other KitKat devices using Qualcomm chips for camera processing, such as the Galaxy Note 3. For these devices, the Google says owners will need to wait for the device manufacturer to issue their own patch."

Verizon Note 3 owners are screwed. Again.

My AT&T Note had this happen to it the other night. I'm sure they will take their sweet time issuing a fix and I'm more sure that the Kitkat update for our Notes will not resolve this.

I saw this for the first time after upgrading Skype to 3.6. Backdated to 3.5 (thank you Titanium) and it went away.

Posted via Android Central App

I haven't notice this bug, my bug has happen twice, my bug stop me to launch camera app, it says did not respond and I have to restart the phone. Is this related?

Posted from my new Nexus 5

I was aware of my battery draining too fast once. I thought I had just taken it off the charger early. I bet it was this bug. I rarely use my camera though so that's probably why I haven't really noticed it. I am glad I can get this update from Google though . I could see a lot of phones having this bug for life.

This happened on my Note 3, running 4.3. It's definitely not a 4.4 issue exclusively. Does that mean I'll have to wait until Samsung updates to 4.4.3 before my Note 3 won't be affected?

Will this update fix the email issue as well? The camera issue is an isolated one but all N5 owners I've noticed can't use the built in email app.

I never had any problems with my camera draining my battery on my N5. But, I was one of the lucky few that didn't have focusing problems with 4.4 and 4.4.1 but since 4.4.2 (which was supposed to fix focus problems) it gave my N5 focusing problems. Hope the next update fixes this.

Posted via Android Central App

I really hope they fix the focus its awful it rendered the camera unusable. I find that using the camerazoom FX app sometimes helps but even then not always. In any case its caused me massive frustration.

Just when I started referring N5 and the rest of the flagships to iPhone users :)

Luckily I have no issues w my Moto X running 4.4.2

More importantly Google needs to introduce slow-motion video capture to the Nexus camera. We have the horsepower to handle it. Please Google! Only feature aside from BoomSound that I miss from my HTC One.

Was wondering where my terrible battery life was coming from lately, uninstalling Skype for now

Posted via Android Central App

guess iv been lucky as i havent had this issue on my Nexus 5. only thing that was draining my battery was the Facebook app so i turned off notifications & problem solved. an update is an update & is always welcome, any idea of when its coming at all ?

Posted via Android Central App

I had this problem on the Note 3 (International) and it's still running JB 4.3. So it seems this is not specific to Kitkat, maybe more a Qualcomm thing!
