Hello guys,
i've bought the p8lite from a few days and it was working great.
Suddendly the camera has stopped working. I keep getting the message "Impossibile avviare la fotocamera, verificare che non siano in esecuzione applicazioni esterne in background (come torcia elettrica). Chiudere le applicazioni in questione e riprovare.".
Translated is like "Unable to start camera, check that there aren't any external app in background (such as torch). Close those apps and try again"
I've not installed any app yet, nor I have rooted or flashed the phone so I really don't know what to do with it.
Help me please!
Thanks in advance to everyone.
Hi, same problem here. I have ALE-04 version (android 5.1)

*clean app data/cache: didnt work
*wipe cache/date partition from recovery: didnt work
*factory reset: didnt work
*downgrade to android 4: didnt work
*upgrade again to android 5: didnt work
*close apps like flashligth: didnt work

Hi,
I had to send the phone back and get it replaced cause it was a hardware problem.
Hope it helps
thanks! but send my phone to USA service is very expensive to me. I had bad luck because my phone has no more than a year.
i will keep trying to repair it.

Maybe flashing twrp and flashing B598/599 stock will help.
Also, when you open the camera app you hear a sound from the actual camera (the lens) ?
I had a similar issue. When I installed a new update etc. the phone was fine. However after switching Google Now Voice (I mean saying ,,Ok Google" from ANY screen) it didn't go well with other apps - in my case it was Camera. So switching Google Ok Voice off helped me. But I'm not really sure, whether it's a same case. Maybe some third party app is blocking something? Good Luck!
im embarrased because camera app works sometimes, i mean, usually works 1 day or less and then shows error msg.
Yesterday i restarted my phone (normal restart) and then started to work. So i do not lose hope

Hi! I have some problems on my Huawei P8 Lite number model Ale-L21.
My Problem is:

That's my problem on huawei P8 lite
Thank for Reading
I've been up and down in this forum and cannot find a proper solution to my problem. It seems that a few of us with certain variants of the G4 Plus have been experiencing issues with either WI-Fi connectivity, SIM error, camera and flashlight not working. In my specific case, my camera and flashlight stopped responding after root. All I get is a black screen when I try to access my camera and my flashlight will not respond. I don't want to have to break root, but is that the only solution or is there a fix?

in stock? how did you root?
Rkschuk from MotoG4 Plus (XT1640)
It would be hard to tell you how because I used several different How-to articles, but from what I can piece together, I used mfastboot to flash TWRP and after that, SuperSU 2.67. It's on the stock rom.

install the TWRP stock again and then go TWRP / advanced / terminal, type the command: echo "SYSTEMLESS=true" > /data/.supersu and then install the super su 2.78.

I just tried it and it still isn't working.
Did you use the tutorial that requires to flash a "modified" system? Rooting systemless should never require you to touch the system.
I just wiped my phone, reinstalled TWRP and SuperSU and the camera and flashlight seem to be working well. Thanks guys!
UPDATE:
I found my problem. When I edited the build.prop file by adding "net.tethering.noprovisioning=true" to enable wifi tethering, it completely disables both the camera and flashlight. When I remove that line and restart the phone, the camera and flashlight are still disabled, but once or twice I received a "this camera is busy" error. I guess I'll have to do a system restore and start over again, without the hopes of enabling wifi hotspot.
Mine s xt 1643 even i rooted my phone... But i didn't checked it even i edited build for Google assistant.... My camera and flash light not working ..
.
I got it back by installing stock rom
Hi!
I rooted my galaxy s7 edge that had stock version of android 7 (nougat) on it using this tutorial: http://www.droidviews.com/install-twrp-root-galaxy-s7-and-s7-edge-on-nougat-g935fxxu1dplt/. Now when I open built-in camera app it shows me a black screen for few seconds and then it says "Camera has stopped" and it offers me to "Open app again" and "send feedback" And it keeps happening over and over again.
Lemma: The reason is rooting.
Proof: Camera app worked perfectly. After I rooted my phone it started to crash like I described above. Then I tried to force quit camera app and delete it's cache/data. It did not help. After that I wiped entire cache partition. Still no help. After that I wiped all partitions except system. That did not work either. Then I re-flashed unmodified original stock ROM. Then camera worked perfectly again. Then again I rooted my phone the using tutorial I linked above. And again exactly the same issue. Camera app show black screen for few seconds and then crashes with exact same error message. ∎
Does anyone know fix for that? And why it happens? Is it some kind of samsung's anti-root thing that prevent camera fromworking on rooted phones or what?
Update [SOLUTION]:
In case someone else has same problem.
My solution was to skip restarts in TWRP steps. No restart between format and installing packages. Restart once when everything in TWRP part is done.
Root doesn't break your camera
I just Rooted my G935F that had Nougat as official firmware and had zero problems with the camera.

But then how do you explain that before rooting camera worked and after rooting it didnt work?
And how do you explain that after I flashed original rom back, camera started working again?
And finally, how do you explain that after rooting 2nd time the camera again started to show black screen and crash?
I have done nothing else than rooting. I have not added any custom mods or anything. For me it starts working again every time I flash original stock rom and shows that black screen and gives error every time I root it.
I downloaded original firmware from here: https://www.sammobile.com/firmwares/database/SM-G935F/ (I chose baltic (only 1 occurrence in the table))
Maybe that specific tutorial I linked is bad one? Could anyone check that?
Rooted my G935F and no problems here for me.
I suggest you follow the tutorial here on xda and try again.
Could you post link to tutorial please? Then I could be sure I used the same tutorial as you did.
PS! Now I also noticed that with rooting I lost auto brightness adjusting and also manually changing brightness didnt do anything. Right now I am back on un-rooted rom because I need camera functionality to work. But would love to get it rooted. Is there any info on cf-auto-root and android 7 yet?

A simple search here you'll find all you need. You are the only person I've ever read of that had camera problems like you've stated after Root. Again rooting won't break your camera.
I've Odin to stock literally hundreds of times testing Rom/Mods/themes as a tester for several teams from my s3 up to and including my G935F.
I've also flashed every Rom available for the G935F and the only ones with camera problems are the Lineage or AOSP Roms which more than likely are kernel related. Start here https://forum.xda-developers.com/announcement.php?a=81
Then this
Here's one

How can you be so sure if you didnt even answer these? Just because it worked for you doesnt mean it works for all. Looks like you dont even try to read what I write. You just read the title of topic and then jump to comment with out even reading the content of post itself...
I have done nothing else than rooting. I have not added any custom mods or anything. For me it starts working again every time I flash original stock rom and shows that black screen and gives error every time I root it.
Also, posting some specific link rather than general starting point would help to guarantee that I use right tutorial for rooting. From these links you posted I didnt find any specific tutorial. I did search and dig these links, but I didnt find any specific tutorials. All I found was some tools and some roms. But cf-auto-root works for android 6 but I have 7 on my phone so I cant use that and I did not find any rooting tutorials on this forums.
Edit: I have also tried this tutorial: https://forum.xda-developers.com/s7...overy-official-twrp-hero2lte-3-0-0-0-t3334084 . The same issue. The camera stops working after that.

Ok here is what you need to do.
Download a logcat app and get a logcat of it forceclosing.
I can't magically look in your device and see what, if anything is wrong.
As far as you saying you've searched well if you really did you would've found several tutorials.
How do I know?? Because I've used them myself.
It took me less than 5 minutes to root my new G935F using the TWRP Guide here on XDA
You seem to be the only one in hundreds that's claiming root broke your camera.
Provide a logcat in the Q&A and maybe a dev can help you.

You could try to reset your settings
Same issue on smg935w8 lost camera and screen brightness. Also can't mount micro sd... we're you able to fix? I thought it was a bad root then I re flashed and the issue came back...twrp 3.1.0 supersu 2.79 and no verity 5.1
---------- Post added at 10:15 PM ---------- Previous post was at 09:50 PM ----------
im re flashing stock and tomorrow ill redo twrp and super su and skip dm verity patch think that might be the issue as it worked before for me last week and i then messed up by turning dev mode off and disabling oem and when i reflashed after that i have been flashing the dm verity patch....
give that a try if your still having issues
had similar issue, my camera app keeps crashing, i went to settings, applications then cleared cache after stopping it, i hope that will fix your camera too

Thanks I've tried clearing cache for everything no luck. I originally thought it was because I might have deleted a system app with titanium but when I reflashed it all (firmware,tarp,supersu,no small verity disable 5.1) I still had the issue.
Lastnight I wiped and flashed the entire firmware. Everything works. Tonight I'm goi g to try and only flash twrp then supersu as I only want root. Hopefully that fixes my issues.
OP have your issues been resolved?
I'll let you know once I get it working on mine and we'll get you sorted out. I believe it's something with the steps or order as I had root fine for a day then had to reflash due to messing around and didn't do it my original way and that caused my issues.
flashed twrp 3.1.0 from odin with auto reboot off.
then booted to twrp. swiped right to mount system,
wipe data(format data) type yes.
mount microsd as mtp copy supersu 2.79 over if its not already on you microsd card.
else just install it from zip
cleared cache/delvik
rebooted to system
log in and setup everything and restore
camera and auto brightness...stilll doesnt work.
ok so after multiple tries to fix this (flash stock) everything works,, root and it breaks tried clearing all cache in system and twrp no difference... then i loaded phone info and used the secret codes to find out that my camera firmware is not installed....so im trying Flashfire to reflash the AP only while injecting supersu and maintaining root.... it is just booting up.....and OMG!!!!it works!!!!
so....for some reason...firmware was corrupting..... no clue why tired multiple methods and nothing... and im not a noob either.....
what finallllllllly worked was.... flash your rom and get root how you would normally. camera/auto brightness/and mounting usb doesnt work....boot to twrp. get your ap md5 file on your internal storage
reboot to system,. get flashfire from playstore or chainfires website
install and then click the + select firmware and select the tar file
only install system....uncheck boot and cp
then in the everroot select injject supersu, preserve recovery
and flash.... it will start flshing and boot to syteem once done..
everything is working nice
finalllyyyy!!!!
hope this can atleast help OP
no clue why i was losing firmware on the flashes
@unit68 Tnx for sharing. This time I got camera and brightness adjustment work out of box. But if in any point of time I happen to need your tutorial, I'll give it a try and let you know.
I am not sure if it is by chance or not but what I did differently this time was:
1) I paid attention to step where it asked to disable auto reboot (can anyone explain why?)
Previously I thought it shouldnt matter so I kept auto reboot for convenience.
2) I did format data, install no-verity-opt-encrypt-5.0 and SuperSU-v2.79-201612051815 and wipe dalvik cache with out rebooting between (Anyone know if that matters?).
Previously I had done it: format - reboot - install no enc - wipe dalvik cache- reboot - install super su - wipe dalvik cache - reboot .
Now I did it format - intall no enc - install super su - wipe dalvik cache - reboot.
I'll see for few days if anything else comes up or if camera breaks down again. Btw @unit68 what happens when you try some bloatware remover that run with root access? Do you get rid of bloatware or not? I tried few of them such as no bloat for example. Some complain that uninstall failed some seem to uninstall the app but when they reload app the app is still there and it's also still in app menu. Just curious if you have the same same issue. And is it safe to delete apk file manually? Or would it cause phone to crash/boot loop? When I ran supersu it complained about knox and asked me to disable it but it never managed to (however root checker tells me I am root). Maybe knox is protecting bloatware? Any ideas?
Flash your able too get it working! It was soooo frustrating. So for Knox supersu asks to disable then seems to hang so I go about my business reopen supersu it'll ask again and then is successful.
To remove bloat I normally just go to titanium and remove the ones I don't want
No issues on that and all my apps that require root work fine (titanium,adaway, flashfire)
This time disabling knox worked too... It turned out that all 3 apps that I used were note able to remove bloatware. App you named worked and also ROM toolbox lite works.
Btw when I google bloatware, the lists are incomplete.... Do you happen to know list of apps that must not be uninstalled? I guess white list would be better idea than black list.
Is installing/uninstalling app same as removing/adding apk files? So that I could cut and paste everything expect file manager and launcher to usb memory stick and then start adding required apps back one by one?
ive seen some samsung debloating software around. i honestly just remove stuff based on manually debloating for last fewyears. if i dont know what theapp is for i google it to see if its ok to remove. normally i remove samsung knox, few other samsung apps, some google apps (music, games, videio), briefings some edge panels, live wallpaper, and carrier branding apps(for me rogers) stuff like that. if you are going to i recommend you do a backup first as it ccan mess up your phone if you uninstall an important app. . also once your do uninstall you need to reboot ... the paid version of titanium allows you to freeze applications so you can try that first before removing it.
I had the exact same issues: camera crashing, blue light filter not working, brightness not working, etc. It was supersu. You need the right version of supersu, it's 2.79 SR0. It's checksum is f4ecbf5814215bf569ff3324fc1c91f5

Interesting..ill check that if I need to to Flash. I have 2.79 but maybe I grabbed an old version or a beta. Mine says 20161205 I think it may have been sr3
Edit _ just checked I grabbed sr0 the stable release from 20161215 not the sr3 beta
Maybe it was corrupt when I flashed

Same for me, i recently updated for pie and i have root using Magisk.
I can take photos, but can't record, the camera just won't record.
Check installed Magisk modules.
After updating from last build my video camera is failing in both stock and google camera , and other third party camera apps. I have uninstalled, cleared cache and Data and tried Safe mode. Nothing is working error is "Something went wrong, Part of video has not saved" is there anything I can do short of a factory reset? I can record video in Instagram and I can make video calls from telegram. Camera MX can record but fails at saving when recording is stopped.
Having the same issue with the latest version of 17.1
Have you found a solution?
I did a factory reset and accidentally ruined my Esim, and then reverted to stock for now PITA.
I did not have TWRP installed at the time just los stock recovery... I would have liked to have tried clearing data cache etc before doing a full factory reset (which didn't fix the camera issue) reverting to stock did but the options were not available
Found a solution!
CERTAIN AOSP roms have an options to spoof your phone as a PIXEL XL.
Namely:"UNLOCK HIGH FPS IN GAME" and "UNLIMITED PHOTO STORAGE".JUST TURN IT OFF AND RESTART. THIS SHOULD FIX THE PROBLEM.HOPE IT HELPS
Also Disable "Allow Signature Spoofing".

The phone is gone but this is important for anyone else in the future. Thank you this is great to know for any other future issues. Although I am not sure it was a signature spoofing issue as I was bone stock lineage OS with no mods and spoofing is not supported/enabled by default
Yea just wanted to share what worked for me!
