camera no more working, need help

Hello,
today i played on my gnex a tower defender game... and i forget to close the game and wifi... after some time (3 or 4 hours) i looked at my phone and it was off (i guess because of the game and the wifi on )
after that i tried to reboot it after putting the power cable in.
it does only bootloop... so i though : super i guess i found a bug on the MIUI rom ....
so i first tried to reinstall that rom (without wiping... because i didn't want to loose my data)... it doesn't change anything
so i tried installing the latest AOKP (b39) still without wiping... i got a lot of errors on boot
so i did it again, this time wiping the data
it boot, it seams to works well... but after 30 min i wished to take a picture... and i got FC
I asked on the aokp thread if this is normal, it seams not
so i installed it again (and of course did a full wipe again... cache, data, davlik cache) but still no camera working
so i force the camera app to close and delete it data, but still no luck
i tried CM9 nightly and Foxhound 0.6 .... every rom refuse to make my camera works
any idea ? (i will try them after night... it is 2 AM now and i really need to sleep)
hope to see some answer in a few hours
Thanks in advance

do you have any nandroid backups saved?

It sounds like b39 may potentially have a Linaro optimization that breaks the camera; guessing. As far as flashing ROMs (markedly different) ROMs without wiping, good luck with that. B/U your apps/data with Titanium b/u or alike.
As mentioned above, hope you have nandroid.

B39 does NOT have any Linaro optimization, nor will future releases for the foreseeable future. Said by the dev himself on the release page.
Anyways, saw this happen on my gfs Sprint Gnex. Fixed it by clearing all and any data from the Camera app, disabling it, rebooting, enabling the camera app, and rebooted again. Haven't had the Camera FC since then.
Also, you should ALWAYS wipe data. Saying that you installed a rom but WITH wiping data makes me think that the Camera most likely doesn't work due to user error.

There's more to Linaro than the tool chain and 03 optimizations. Last time I looked at the aokp code review there were plenty of merged Linaro bits.
Edit: I agree optimization was the wrong choice of word.

thanks everyones for answers.
i will try the method you said and cross fingers for it to work.
if not i will try an old nandroid backup
if not..... well i guess i will come here and cry for help

very fast feedback...
i let the phone turned off all night
i turned it on and tested it BEFORE even doing what you told... and it works again
crazy....
yesterday i reboot the phone at least 20 times and the problem was not gone

Remember. A Rom needs to settle and dig it's teeth into the phone.
It actually takes 2 weeks for all the bugs to work there way out I believe.

Art

Can you enable ART on G3?

Yup just did it and its rebooting.
Its under developer's option > Select runtime system > Use ART
Edit: After booting up the system with ART, the camera app immediately crashed. Whatsapp worked fine. The phone also got really hot when android was switching over to ART from Dalvik. Going to switch back to Dalvik when the phone cools down.

phone got really hot WHEN switching or after switching?

Phone gets really hot while switching. It cooled down after it booted into art mode.

Its doing a lot switching to art ....
Here are some of the major new features implemented by ART.
Ahead-of-time (AOT) compilation
ART introduces ahead-of-time (AOT) compilation, which can improve app performance. ART also has tighter install-time verification than Dalvik.
At install time, ART compiles apps using the on-device*dex2oat*tool. This utility accepts*DEX*files as input and generates a compiled app executable for the target device. The utility should be able to compile all valid DEX files without difficulty. However, some post-processing tools produce invalid files that may be tolerated by Dalvik but cannot be compiled by ART.
So it its compiling every app you have on the phone to start on time instead of the little lag you get when opening some big apps.....so in reality your phone won't have to work as hard using art after the first time....

I wish i can benefit from those point you've pointed out. but unfortunately many of the LG doesn't work with ART and will crash when i attempt to load it up. for instance, the camera app stopped working after switching over to ART.

I think LG should fix the camera issue. I've had the same problem with G2 over year ago.
TA

That is the only thing the apps need to be updated to support art and soon 64bit

Phone seems faster with art but quadrant score is very low 13k Max

Switched to ART from day one. Not had a single problem. Camera and everything else I've tried works as it should.

Can somebody check benchmarks both on art and dalvik? It's weird to get worse scores right?

Same here...

Depends on some apps you use. Not all apps are switched to art yet. I use a few that don't work with art. It's still not supported

I tried switching to ART but the whole phone became extremely slow and laggy. Did any of you guys experience this? Should I leave it for a while to sort itself out?
Also, a lot of my installed apps disappeared from the launcher? Is this normal as the apps do not support Art or should they still show up?

The first reboot after the switch from Dalvik to ART took about 10 minutes for me. It depends how many apps you have installed, as it needs to pre-compile all of them. After that I didn't notice anything being slower or missing.
In theory ART should make it faster to start applications and should help with battery life as well, as it doesn't need to compile the apps on the fly as you start them. That's the theory anyway. I had ART on on my Nexus 5 as well from the beginning and none of the apps I've used misbehaved.

Device running sluggish/lagfest stock rom AT&T

I've had my g3 since it was released for pre-order. The past two days the device has been running really slow, everything I do it seems there's a second or two delay especially with text input, its just stock rooted with xposed and greenify, titanium used to freeze all the bloat but that was day 1, just yesterday I was messaging someone on Facebook and there was a delay in typing a message, haven't added many apps on the device either, also my phone doesn't get hot and I don't leave my brightness no more than 40%, usually at auto 0%, I really don't want to factory reset but I might have to seeing its to slow to use yet there isn't really much running on the device. Any help would be appreciated thanks
Also in dev options animations are turned off

mine was running like that when using the chainfire supersu app, i was also getting bad battery life due to a wakelock related to it. i switched to the chainsdd app and now the phone is super smooth and the battery life is greatly improved.
ymmv

I also got a parsing error when trying to install g3 tweaks box if it means anything, might try a factory reset or an exchange, thankfully I have a nexus 7 2013 but it's a piece due to the plagued random reboot problem

i used towel root for what it's worth. also, if you installed anything around when it started to bog down, maybe uninstall recent apps and see if that helps

i'm on the 1.1 beta, installed fine. i haven't used a benchmarking app in a long time, but that's a pretty normal number from what other reviewers have gotten on this phone

Art vs dalvik going back and forth

Is there anything wrong switching back and forth between ART VS DALVIK?
IT seems that some games won't operate properly in one or the other.
That said I notice that I cannot install real racing 3 from the play store. In fact if I search for it. It does not show up. If I click a direct link for it it says my device not supported.. Any ideas?

Maybe the game doesn't officially support our resolution.
For some apps that don't want to install via play store I install them through Amazon app store, but that's only if they are also available on there because it doesn't do some of these "officially" supported checks.

No issue at all. Have smashed b/w dalvik and ART several times. Finally on ART, no lag, amazing battery life.

OK cool thanks. So save to experiment

Curious, I switched to ART once and after every time the phone was rebooted it came up as one app was being optimized, anyone else had this happen?

This doesn't happen to me on my G3 or Nexus 7. Both of them only upgraded the apps once, so I have no idea what's going on with your phone.

Same here. After switching to ART, every time the phone is rebooted, it optimizes apps.
ART runs better for me.
Dalvik should have better compatibility.

I know some games simply don't work with ART, they FC immediately. Developers probably won't update it until L is out for a while.

How to prevent Android from killing apps?

So, I have this issue, where most of my apps can't stay in recent apps overnight. They all get killed, all but 5 I have noticed. I did the battery optimization thing for all apps I use on a daily basis. I have edited build.prop file and added sys.keep_app_1=com.whatsapp and so on for the rest of my apps. I also did that in the local.prop file. None of it worked. How to prevent my phone from killing apps overnight?

Nobody?!

If you are rooted you might try the app LSpeed and use one of the build in RAM profiles.

I am rooted. OK, I will try it. Thanks. It shuts my app very VERY aggressively. For instance, I was watching some youtube video yesterday, and in the other app I was searching for some products and was going back and forth between YouTube and Google Chrome, and every couple of times it restarted YouTube app, even though I was using it 2 minutes ago.

Both youtube and chrome are resource hungry apps, that's why it keeps reloading.
I guess your device is 3 gb version as mine.

I have the 4 gb version as well and I don't face such an issue, if nothing works try factory reset, absolute solution :good:

Tried it already, didn't work. Try leaving 10-15 apps opened in the evening, and see in the morning if they are still in recent apps. And tell me tomorrow.

Well, then you probably need a custom rom. Android One is known to be optimized for dumping non needed tasks. You could try to disable battery optimizing for the apps you would like to stay alive.

Tried that too, didn't work.

My previous phone was 2Gb running android 6. Now i have a mi a2 life 4Gb and it is OK except for 2 games.
Apparently there's some AI that learns what you use but after many weeks no change.
Most apps open pretty fast. It's only these 2 games that I run daily. Annoying to have to wait for them especially since the old phone was able to keep them cached.
I tried the low-memory config (magisk module) but it didn't help. I guess android has changed its algorithm. I'm resigned to it.

It's insane. What's the point of having 4, 6, 8 or 10GB of ram if you can't use it?!

Connect it to a monitor, install Taskbar app and SecondScreen app, enable Freeform windows and turn your phone into a mediocre PC. Assuming you can get all the resources back from OS's hidden service threads of course.

Facing the same issue
facing same issue specially after android 10 update. Change apps back and forth even in recent apps menu kills the app. My phone is 4/64.

Android 10 has a known problem. Rebooting helps. For how long seems to vary. I get a week or so, some people only get a day.

I had the same problem when I was unrooted during the Android 10 update crash. After rooting and installing Lspeed again, Android is not killing apps anymore as I set these settings
