[Q] Camera FC when i try to clicked image and shows error...

hi friends i have rooted official LPY ics rom and whenever i try to check image after clicking new image and try to see image from left side bottom camera image saved folder button it automatically FC and shows error.... "unfortunately camera stops working"
any solution for it?
Which phone you used..
Can you post the phone model?
According to your description, maybe the driver of Camera has a problem or the hardware issue. You can check the camera or the shell of the phone, closed or not.

In regards to camera problem
Ok, so i'm in exactly the same situation you are in as the recording feature of the stock camera app or any app failed to work for me (froze and crashed app). So far I have found two fixes, the first one thanks to a user called "RambJoe", so thank him if it works (it didn't work for me )
Fix 1-
1. Install/Open a file explorer on your device (I used ESFileExplorer)
2.Enable "Root Explorer" (Under Menu>Tools>Scroll to bottom on ES)
3.Navigate to system/etc/init.d/80cfw (This file seems to be missing on my phone, and I have found other people who have not got it as well. I believe it is because this guide isn't compatible with the International version of the SII i9100, so if you do not have it, skip to Fix 2)
4.Change the permission of the 80cfw file to rwx r-x r-x (Select the file, tap on "More" and scroll down to "Properties" and change the permissions from there)
5. Save and reboot, that should do the trick!
The next fix requires you to have Titanium Backup (FREE) to be installed or another such app that can delete/modify system apps. You can thank me for this one
Fix 2-
1. Download this apk *DO NOT INSTALL YET* - http://forum.xda-developers.com/showthread.php?t=2340858 (Thanks nexūs0 for upload)
2. Open up Titanium and back up, then delete your stock Gallery app
3.Find and install the apk you downloaded in step one
4.Open up the Gallery app and you should find the camer ON THE GALLERY APP ONLY working correctly (it did for me, anyway). The other camera apps still do not work
Don't forget to tell me if this helped you and feel free to PM me if you need assistance!

Snapdragon Camera

Hey,
I just installed cm13.1 by Team Superluminal on my mi4c. Somehow I can't find snapdragon Camera on my device. Can someone please post a flashable zi for the app. Regards
It's already the default camera app. No need to flash anything. To enable some more advanced feature though, tap 7 times on Screen Brightness option and it will unlock additional setting.
For me it is not installed the only camera app I can find is the Google camera. I used the open GApps stock package. Maybe this somehow replaces the default camera app?

I guess. In all of my flashing i install the mini package though.
So can anybody please extract the snapcamera app as zip or apk and post it here. Would help me a lot. I think it's possible using fe titanium backup.
Edit I tried reflashing the rom without GApps. No changes : Google camera remains the standard camera apk

You need to wipe before reflashing the ROM, otherwise Google Camera may remain.
Use a version of the GApps that does not contain Google Camera. Google Camera replaces your default Snapdragon Camera: https://github.com/opengapps/opengapps/wiki/Package-Comparison

Stock camera apk for Find X2 Pro

I messed up my camera by using an APK form apkmirror.com. Probably i choosed a non compatible camera. Stupid idea.
I tried them all by now and stil the camera is not working. It goes as far as the permissions for location, but then it crashes.
I really hope that someone can provide me a link for the stock camera APK for the Find X2 Pro (ColorOS 11).
Thanks in advance !

Try this : open camera app properties and check if you have an option to uninstall the updates.
Otherwise, factory reset of the phone should revert to stock app.

Thanks for your tips. !
I had tried the 'Uninstall updates' option already, but it isn't there unfortunately.
The factory reset is an option i want to avoid for now. Maybe later.
