Weird camera bug

I have a weird camera bug on my phone.
Since a few days ago, every time I switch to the front camera, the camera app crashes and I have to force close and delete data to get it working againg.
This happens on multiple roms with multiple camera apps, so it has to be hardware related.
I opened up my phone to change the screen a few weeks again, but everything was working fine after that until now.
Now the thing is, I opened up the phone again to see if maybe the cable went loose, which it didn't, but when the back was removed the camera was working correctly.
Closed up the phone again, same thing as before, front camera does not work.
What could the reason for this be?

It's software not hardware. Mine won't take screen photo's. It says not enough memory with 4gigs free. I use a widget with extensive reboot /recovery options and that has a screen grab that works. I've had the bugs you have and had to switch roms, providing it's software

How can it be software when the issue persists on different roms, stock roms and after factory reset and with different camera apps. Added to the fact that the front camera worked when I tried it with the phone back removed

Camera Failed

So a few weeks after I got the phone I started getting the camera failed message. I've tried every option I've had, clearing the cache, force stopping, removing the sd card, turning off smart stay, even hard resetting the phone and using the complete data cache wipe. Finally I took the phone to samsung and they did their software update/data fix thing and it worked. For about 10 minutes my camera was just fine. Then the error came again, but not as often. I would get the error once then right after the camera would work. So for most of the day everything was just fine. However, then towards the end of the day, it's gone back to how it was before with all error with almost no successful camera app use. I had shown it to samsung again and they were just stumped. They said to try a complete wipe, but I've already done that with no success.
I bring this up because I can't find any recent threads on this issue. Also from what I've seen it's a software issue so do I just wait for a fix for RMA the phone. Everything else about it works fine. Does anyone else have this issue?

Warning: "Camera failed" imposible to solve but dialing *#0*# the camera works
Hi, I have a problem with my front camera in the Galaxy S7 (SM-G930F). It doesn't work and every time that I enter in the front camera appears the message "Warning: Camera failed"
The Rear camera works perfectly but since I've bought the S7 I never couldn't use the front camera
Here is what I have tried:
- Force Stop, Clear Data, Clear Cache, and Clear Defaults
- Clear Cache Partition in Recovery
- Factory Reset through Settings
- Factory Reset through Recovery
- Installed 3rd party camera app
- Installed another OEM ROM through Odin
- Repite everything
And the camera never work.
But.... by entering *#0*# into the dialer and picking Front cam the camera works perfectly and I can take a pictures. but through the app it doesn't work
Another thing that I can do it is, install the Dual-camera MODE and I can use the both two cameras at the same time although the front camera locks very blurry but it is another problem
I need to know if it is a hardware problem or a softwared problem. I don't know if I replace the front camera It will work.

Hi! I have this problem with my front camera I tried every option too and also install another Oficial ROM through odin but it didn't work
Did you solve it?
Try to put *#0*# in the dialer and test the camera. tell me if it works.

LG g5 main camera broken?

Hey there, I have a major problem with my LG G5 SE and it's really annoying me. One day a few weeks ago the camera app decided to crash and when I went back in I found I was in trouble as the main camera was not showing at all it would glitch out completely and show the front camera and back wide angle only and the interface for rear and front are the wrong way round... I've tried everything out there to try and fix the main camera not working or appearing anywhere even in third party apps... I've even factory reset it so many times did nothing, and that failed to sort out the problem so I am really stuck on what to do next as it has such a fantastic camera and somehow has stopped working recently, image below is what it always shows even after cache and data cleared i try switching cameras in app and shows that again every a time I do so, and no idea why but it seems a software fault which I cannot fix myself clearly as I've tried everything out there, any ideas please as I do not know what to do...(ID RATHER NOT HAVE TO SEND OFF TO BE REPAIRED AS IM SURE ITE FIXABLE) Thanks

Rear camera stopped working randomly

Yesterday, I could use my rear camera normally without problems. Now every app that uses the rear camera (Camera, Snapchat, etc.) crashes instatnly without giving chance to switch to front facing camera. Tried factory reset like a million times without any luck. What could be the possible reason and how can i get it back to work ?
HTC U11 Life Android One 8.1.0 (EU/PL) 32 GB

Same problem here...any fix for this?

same problem here, any solutions?

add another person. My wife's u11 just stopped working no matter the resets, forced RUU updates (stock) and everything.
Spoke to HTC they said they'd fix it but said they have no timetable on when they'd return it! They're falling apart.

This is U11 life thread and not u11, and its related to a not working camera module and not the whole device. For HTC repair i can tell you it takes something between 3 and 12 months to get the device back. No joke you can read about these long repair times a lot online.

same issue here. No fix but to confirm it's a hardware issue, I use Google voice commands to say "Take a selfie" - which launches the camera app with the front facing camera selected.
If that works fine, then it is likely a hardware issue with the rear camera, you can contact HTC, though your mileage may vary.
If front-facing camera is also not working, that could indicate a software issue you could try resetting the camera settings back to default. Other possible causes might be the disk / sd card where photos are being stored when camera is launched....

Back camera stopped working completely here, no picture, just black and the camera app closes after 5 sec. Resetting camera app did not help. Other camera app (open camera) has the same problem.
Front camera works from “long tap / selfie cam”

Camera app crashing when using wide aperture - Huawei Mate 9 Lite

The camera app always worked well, but since I updated it to Nougat, every time I take a picture with the wide aperture feature the phone freezes and the photo is not saved. I have to reboot it in order to use the phone again. I've tried deleting the cache and data of the camera app, making a factory reset, nothing worked. Huawei support says that it might be a 2nd camera hardware problem, it was working until i received the update. Anyone know how to fix this? Also, in case i wont be able to fix it, which camera app do you suggest that has a nice portrait mode?
Thanks in advance
