[Q] My Camera Is Now Completely Useless.

For some God forsaken reason, the camera in my N5 is a pile of crap. Let me list the issues:
(Note I'm using the stock Google Camera app and have tried CM Focal with identical results).
Switching from Rear to Front camera takes a stupid amount of time, usually winds up crashing the Camera app altogether.
Switching from Camera to Video results in a grey bar, 1/10th the width of the screen, spanning the entire length of the right side of the screen. The app usually crashes after this.
Videos usually can't record, the screen freezes, forcing me to hit the back or home button.
When videos do record, they're corrupt and cant be played on any windows machine or in any program.
Sound quality is laughable. (wasn't when I first bought the phone with 4.4.2 on it)
Snapchat usually can't even launch the camera and asks to restart the app. Usually results in me having to reboot the phone.
When the camera does work in Snapchat, pictures come out fine, but switching cameras usually reproduces the issue mentioned above. Videos, however record only 50% of the time. The times they dont, the screen freezes, resulting me having to restart the app.
When videos do actually record in Snapchat they have about a 50/50 of being unable to be played back, resulting in the error message: "Can't play this video".
On rare occasions, using the camera in Snapchat results in the screen flickering rapidly for a few seconds and then the phone reboots... The last time this occured it wiped all the data to Facebook, Snapchat, and EvolveSMS.
These symptoms exist in both Vanilla KitKat 4.4.4 and CM11 (Snapshot M8). Yes, I have reinstalled Snapchat. I've also tried toggling on/off HDR+ to no avail.
My Camera is basically useless and it's extremely annoying. It has even caused crashes that have wiped data from my phone. Hardware related? Software related? I'm really at a loss here... Any help is appreciated.
Well first try a complete fresh install to see if it's just software related

Factory reset, wiped case and dalvik, freshly installed CM11 last night before bed. Same symptoms exist as they did before.

Light won't go off

On stock 5.0.2 and been having no issues until few minutes ago. I noticed the phone getting warm and burning battery. Killed some apps,etc.. Then I noticed the camera light (flash) was on. Tried to open the camera to stop it but failed as camera was unavailable.
A shutdown did the trick but very odd. Anyone else experience similar?
Just a tiny bug, had it once and the flash light button was gone too, just force stop the camera app in settings and it should solve it.
Weird. Odd part is that I wasn't using the camera around when it happened

Z5 Camera app issues

About 70% of the time the camera app on my Z5 works fine, but the rest of the time I seem to get issues such as
- failing to start at all
- starting, but never loading the camera controls (so all I see is the live camera feed)
- starting fine but crashing in actually taking the picture (usually after a couple of successful pics). This pic doesn't save
- video recording fails to start, but looks like it has. Pressing stop actually starts the video
These are all quite weird and seemingly unrelated issues, but wondering if I'm alone in experiencing this, and if not, if anyone else has found a fix?
Thanks
Anybody able to help hear... most frustrating thing missing key moments of my baby's life simply because the app decides not to load properly and requires a reboot...

[SOLVED]Weird black screen happening

Hi guys. Im gonna tell about a problem which does not occur in many apps. In my opinion it happens when i open an app that neeeds graphic card but not for sure. Here is the problem.
Ex. When i open a game or youtube video nothing is wrong if screen faces up. Nothing at all. When i tilt the screen down it blacks out even sound goes off ( phone is on) and then i tilt phone back up everything goes on working. It only happens in these kind of apps. Any ideas ?
-----------
I solved the problem by uninstaling updates from samsung's game tool/game mode app from aplication manager.

Instagram stories and front camera problems [Lineage 15.1]

I've searched here and on other forums but can't find an answer to some camera related problems.
I'm using 15.1 Osprey June, 1st build on my Moto G3 2Gb Ram (XT1543).
PROBLEM 1: front camera not working.
This is happening for a long time, since I was using stock ROM (my phone came with 6.0, but that time both camera worked fine).
Don't know when this starts, cause i didn't use front camera very often, but when on 6.1 this already happened, the change camera icon simply disappeared.
I've tried all tricks, format the phone, boot on safe mode, clear chaces, etc.
I've used Lineage 14 for a while and now I've made a clean install of 15.1 and same thing.
Back camera works fine for photo and video using Footej Camera — the first time I opened this app, there was the change camera icon; I clicked and get that camera error message, and now the icon disappeared again. Installed MotoCamera_Mod_6.2.5.16 and same thing: back camera fully functional, front camera no icon or options.
Didn't drop my phone, but i'm considering some hardware problem.
Anyone has a link to a DIY fix (or at least try)?
Here in my country, the cost of the repair probably does not pay...
PROBLEM 2: Instagram stories not working
photos works fine, a click the button and can add to my story, but when I record video, after it's finished the buttons doesn't appear and the app freezes.
on "hands free" the image freezes during record, when try to make a boomerang "an error occurs" message appears and the **** goes like this...
I've removed and install back the app, have the last update, etc.
Is someone else having this problem?
thanks!
problem solved!
if someone else is having similar problems, here's the (obvious) solution:
just do a clean flash!
I did it and everything is working now (instagram stories, other camera apps functions and GPS).
except the front camera, probably due to some hardware stuff.
