[Q] camera sometimes freeze - Android Q&A, Help & Troubleshooting

Hi folks,
I have a haipad i9300 mtk 6577 4 days ago the camera start to make trouble. Sometime just show black screen and after ask for a force close.
I tried to delete the old camera apk and installa brand new...I give to JB 4.2 camera a try to see if it works...nothing still the same. Black screen and after several touch ask for a force close. I guess is not an hardware problem because sometimes it works...what can I do?

I notice if I press several time and I force close then the camera app cannot connect to camera. This happen 4 or 5 times...then if I am very lucky the camera rebirth and start working again...It seems there is a kind of problem between the app camera and the camera hardware...because every camera app have the same issue, so maybe the problema is after...maybe some libs or something like that...any idea?

Odd update...I have a torchlight app with its widget. I notice the torchlight has the same issues of the camera. In fact it freezes and often I need to force close. The strange thing is if you turn on or turn off after few timers you can heard a kind of "click"...the same click you heard when you activate the camera...after that if you turn on the camera it is working. So I guess the torchlight and the camera are linked in some way. Of course I try to unistall the torchlight app...nothing the camera still not working.
Any ideas?

I'm not expect ,but
if something using start using camera (for example torch widget app) then other program cannot access to camera,so if program was not design for that case it will crash. (I know this as When I writing my app i spotted the same problem as You. ).
So i guess something using camera and that cause your problems.Try to find how many programs/services use camera and close all of them and then check/

That's my thought...in fact I'm pretty sure something is bothering the camera app...but...I did an hard reset, so a clean system, but the camera still freeze so I assume is not an application I installed. How can I check which application is accessing the camera?

[Q] How to fix camera problem?

Since I updated OTA to 2.3.6 build 4.5.141, I have been experiencing a problem with the camera as it shows a black screen (both still and video) and crashes after that.
I am willing to root the phone and install flash a ROM if that could be helpful. I tried a factory reset, SD format/unmount, battery pull, reboot, and everything possible with an unrooted device.
Warranty period is over so I can't ask for a replacement.
Any help is appreciated.
Camera
I had similar problems with upgrading to ICS Roms.
I fixed the problems with installation of Videocam Illusion and ProCapture or FastBurst Camera. I don't know if it is suitable for your Rom.
The only problem I see now with these apps is that I can't open, let say, ProCapture or FastBurst and after any camera or camcorder apps. The only to get these apps to work is to reboot.
Not working
Thanks for your feedback.
But I tried installing all those apps but they all give the same problem (black screen, which later freezes). I tried changing the resolution of the camera and then the camera app did not open at all saying: camera unable to initialize.
Occasionally, it shows a large camera icon in front of the screen and then it just closes down saying 'Activity Camera (in application Camera) not responding.
I do still think it is a software (not a hardware) problem because the phone has not been exposed to any physical damage whatsoever and everything else works smoothly on it.
I am already considering getting a replacement camera but thought I'd exhaust all other options before doing so as it does take a while to get a replacement. Luckily, it is under warranty.
Thanks again.
Id you're looking for a good stock based rom id try nottachrix. I've been on it roughly 2 months no issues

Camera closes after taking pic...

Hello everyone. I just got this phone the other day after returning the galaxy s5. I am loving it but I have one issue and maybe I'm just doing something wrong.
Everytime I take a picture in the camera app after tapping the check button, the camera closes and I return to the home screen. Does anyone else have this problem or is there something obvious I'm doing wrong?
Not normal. If the phone is stock (unrooted, etc.) I would try a factory reset (backup any personal data first) and see if the problem persists.
Only time I see a check in camera app is when sending picture via mms and it asks where I want to send [email protected],camera etc... if this is case of attaching picture directly from camera to an mms then this is a normal function, if taking a picture and it just closes then this is not normal reaction
Well it seems that the problem has resolved itself. I was just about to post a screen shot of the check mark so you guys could see it and then it just starting working as normal. Thanks for the responses and I'll post here if it comes up again.
Ok the problem returned... I showed the issue to a buddy who has the same phone and it also turned out that I was missing several options on the camera. I did a factory reset and the problem persisted.
I think I found the issue... I was using Google Now Launcher. Apparently that launcher doesn't play well with the camera. I uninstalled the launcher and voila, all the features (video, zoe, dual camera,etc) are back and the camera no longer closes after taking a pic.
Anyone else want to test this theory and see if happens?
confirmed issue and workaround
Hi there,
I can confirm that the Now launcher uses the native Google camera instead of the Zoe camera. I have also found that from the lock screen with the now launcher installed, unlocking by pulling the camera icon opens the full HTC zoe-enabled camera again. I find this super annoying as I'd like to have Google launcher and have the camera work properly. Anyone know a fix for this other than my workaround?
Ditto for T-Mobile HTC One (M7)
There's a lot I really like about the Google Launcher, but this just drives me nuts. I didn't really understand the workaround suggested here ( though I have no doubt it works). But the suggestion sounded on target. So, I went into my app list and shared it from there. It didn't do the funky stuff any more. I wonder if there's a setting to change that behavior: like someone thought, Hey, take a picture and go back to our regular programming? It's a shame because I really feel that the Google camera takes better picture.
In any case, just to let folks know that this is a real problem. The OP was on target.
To anyone else having this problem that does not use Google Now Launcher, another app that causes this is Omni Swipe. The default camera button in the tools section isn't the right camera (not sure what it's trying to access but still). If you add the correct camera app to the app section, it'll be fine.
Yes, this solved my problem as well. I went back to the default launcher and now the camera is working fine

It seems that i /m facing the same problem here. I'm running the AEROM v5 and out of the sudden the camera stopped working, the flash as well. Every camera app that i used only opens the front camera and i cant even use the LED light as a torch. I contacted the seller and suggested a factory reset , i did it with no success. i think that it might be a "missing driver". I do not know a lot apart from flashing roms, recovery etc. Trying to work it through.
Did you try to open the cover and check if the camera is connected properly at the board?
Sounds like hardware.. Any other experiencing this?

It is a hardware matter , at least for me

Camera error, Camera unavailable error.

Hi,
I am using LG V30+ (LG-H930DS) past one year. For past two months, my default camera app stopped working. I have tried with restarting the mobile, clearing the data and cache, force stopped the app also. Nothing works. I am receiving the following error
"Camera Error;Camera unavailable"
Also in other camera applications the selfie cam is not opening. If I select the change camera option to take photo in front camera, its redirecting again to rear camera. I am unable to open the camera through applications like WhatsApp also. Even face detection is not working.
I haven't dropped my mobile or damaged by any other means like water also.
So can anyone of the members in our forum could help to rectify this error?
My mobile IS currently running in May 1 2019 security patch. Software version is V20f-IND-XX.

1) Perhaps there's a conflict:
"Camera Error;Camera unavailable"
"Also in other camera applications the selfie cam is not opening".
That first error usually means something else is using the camera. Uninstall the other camera applications to test. You can always re-install later.
Back when I had Moto Maxx XT1225 and custom ROM, I ended up with two Galleries and my camera would crash when I tried to use it. I ended up having to freeze one of the Galleries in Titanium Backup.
If you have multiple camera apps, it's possible one of them is always running in the background or something which prevents the others from using the camera. Just a suggestion to uninstall them, temporarily go back to stock LG camera only and see if that solves the issue. Then you can add them back one by one, rebooting in between, see if there's a conflict again (if that's the reason).

2) Yeah, could be hardware failure. In one instance, someone's selfie camera was not working -- wouldn't open. But turns out the problem was actually the rear camera. They had to REPLACE THE REAR CAMERA and then the selfie camera worked. The rear camera was faulty and wouldn't switch to the selfie camera.
This camera error, camera unavailable just happened to me. This is the 2nd time its happened and rhe first time i had to do a complete factory reset to restore my camera function....i didnt know what caused it then but it happened again and I think I know what may have caused it.
So this time just like last time I had my SD card filled with photos mounted and taking photos with this new phone created a 2nd "camera" folder.
I moved all the photos out of that folder into my existing SD card "camera" named folder and this inadvertently deleted my newly created LG "camera" folder...
I noticed my next time I went to take a pic I got the error....im thinking its related? Any weight to that? How do it restore or create that folder again...? To check before im forced to factor restore again??
Thank you!

stock camera keeps stopping

Hello,
I recently got a mi a3.
Today the stock camera ''keeps stopping'' , I can still use open camera and Google camera redmi note 7 port by BSG. I installed the last update with 5 July security patch yesterday maybe it's linked.
Does anyone have the same problem ?
Does anyone know if we can use the wide angle camera with an other app ?

I already tried that :/ Even with safe reboot it doesn't work.
I'm going to factory reset.
I'm having the same issue. Also, the camera is very laggy, whenever I click a photo the camera takes 1 or 2 seconds to respond.

Yaaaaay It worked perfectly. Tnxxxxx
Just open settings -> search "Usage access" -> tap on the result -> choose "usage access" from list -> allow camera. DONE
(It's suspicious why camera needs usage access tho!!!!)
