LG G4 - camera flash and camera not working - G4 Q&A, Help & Troubleshooting

So I know about the typical camera issues that this phone has, however, when I noticed the built-in camera app start having issues with the rear camera, I also noticed the LED flash was also starting to go black in the bottom left corner.
Does the LED need to be working in order for the camera to work?
I also cannot use the flashlight, as it shows the error that it can't be used in Camera or other apps (no surprise, positive it's burnt out).

Sensor problems (brightness, auto rotate etc)

Since a few weeks my LG G3 has te following problems:
- Auto rotation is not working
- Camera is unable to focus frequently when starting the app for the first time
- Camera is not saving while recording, but photos are working fine
- Screen is not turning off while making a phone call
- Auto brightness is not working
- Sometimes the infrared sensor at the front side of the screen is constantly turned on, untill I reboot
I've dropped the phone once, very softly from like 20 cm, on the right bottom side.
The strange thing is that the problems occurd step by step and sometimes disappeared after rebooting, but now all the problems listed above are unfixable.
Checked CPU-Z at the sensors tab, none of them seem to work:
And the original values from a fully working LG G3:
Any ideas on how to fix this, it's getting really annoying right now.
Thanks,
Niek
I guess returning the phone to LG is not going to work, since it has already one scratch mark on it from falling.
Any ideas?
hi @Niekjuh,, how the solution for your phone ?
Returned the phone, they could not repair it so returned the money instead.

[Q] Force apps to use only front camera

Hey peeps,
Yeap, I did search a lot before posting it, but apparently the other topics are not quite about the same thing.
My HTC One M8 rear camera is not working anymore (buzzing sound, it is a hardware issue and I can't send it to repair for now).
I need to use some apps that turn the camera on automatically, but they don't provide the option to change from rear/front. So, when they turn the camera on, they use the REAR camera, which is not working (it opens normally, but it can't focus, so it's useless).
So, I need to force apps (and, hopefully, the whole system) to use the FRONT camera as default, maybe by disabling the rear camera? I don't know yet.
Does anyone have any light about the process? Is there any filesystem I can edit to disable rear camera / force front camera?
I'm on Marshmallow, CM13.
Thanks!

One M8 Rear Camera Not Working..Plz Help

I have had this phone for 1 month and rear camera stopped working. when i try opening the app, it instantly dies and goes back to the home screen. Also on every app that uses the rear camera the screen shows up black and will not show anything. My phone is not Rooted

Front camera doesn't work.

Hello,
After launching the camera application, when I select the front camera, the app shows a black screen for a few seconds, then crashes back to home screen with no error message.
The rear camera and everything else work fine.
I replaced the front camera or/and the daughter board the symptom is the same no front camera works.
I need help please.
Best regards.
I have the opposite problem. After removing my daughter board, the camera app just exited. After replacing my rear camera, only the front facing seems to be working (and no flash)

CAMERA ISSUE - Reversed Camera - Rear Camera opens "Front Camera Harware" vise versa.

CAMERA ISSUE - Reversed Camera - Rear Camera opens "Front Camera Harware" vise versa.
Hi,
I am having this weird issue where my phone opens the "Front Camera Hardware" and thinks it's the rear camera and Rear Camera opens with the front camera settings and it shows a mirrored view.
Sometimes it just will not launch and will just show yung the Camera functions with a Black Screen.
Installing a different camera app makes it worse as the camera shows an inverted picture for both front and back cameras.
I tried to do a Factory Reset but it doesn't fix the issue.

Got the same issue on my realme 3 pro, found any fix yet?
