[Q] Force apps to use only front camera - One (M8) Q&A, Help & Troubleshooting

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!

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)

LG G4 - camera flash and camera not working

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).

First rear camera broken, second rear working. Any way to choose?

So using the *#808# diagnostic menu I can see the the first rear camera is inoperable but the second rear camera and the front camera work. I know about the *#*#1576#*# or whatever thing that pulls up the camera and should let you cycle through which one it's using. However because it first tries to pull up the dual camera before you can switch, the app crashes. I also tried the nokia camera that lets you select individual camera modules and the same thing happens. Is there anyway to change my camera preference or to disable the first camera so it defaults to the second rear camera?
Thanks.

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?
