Back camera stopped working

My back camera/light has recently stopped working. This phone is less than a year old so this issue is frustrating. At first, I was able to reboot the device and the camera/light would work for about 30 minutes or so. A month later, it only detects the front camera. Now I can't select or add the camera in the Camera app. My flashlight app just freezes if I try to open it. I have some screen shots below. I used an app called System Droid Info to get my hardware information and it seems to display only the front camera specs as if it's the only one connected (maybe I should try another app?). Not sure if this is related, but it also started occurring around the time I installed the latest OTA update.

Things I have done:
-Cleared Camera data/cache and rebooted
-Disabled/enabled Camera app and rebooted
-Force close/reopen Camera app and rebooted
-Powered device off/on
-Factory reset through bootloader
Does this sound like a hardware failure? Are there any other steps I should take? Any help would be great, thanks!
Sent from my HTC6535LVW using XDA-Developers mobile app

hey @poupdujour, this happened to my M9 whilst i was trying to capture lightening in a thunderstorm (not relevant, but i thought i'd give you a back story) I was able to get the camera "working" through 3rd party apps like whatsapp and instagram but the image was flipped upside down. did everything you went through and even went back to stock, nothing helped.
Think it must be a hardware issue, I sent mine back to EE and got a 24hr replacement.

Oneplus 3 camera and gallery wonkiness

Hey guys,
I've had the OnePlus 3 for a wild 2 days and its definitely the best decision I've ever made phone wise. I like the camera, though it does oversharpen a bit, but the thing that really annoys me is how they have done the gallery with the camera. I'm not sure if they have a consistent system for when you are able to slide to see photos and when you cannot, but it seems arbitrary to me.
Basically, they have chosen to only allow the user to look at the pictures taken in that app session, which I can understand for some situations, but its a strange feeling when I open the camera app (double click home or launch app) and swipe to see my gallery and it just keeps saying No Photo. Seems like a strange departure from previous camera apps I've used. But sometimes, I open the Camera app and can swipe to any picture. I don't get the differences if there are any.

Anyone have a good rationale for it? This is not just me, right? Am I missing something?
Thanks and I hope to OnePlus with all of you in the months and years to come.

This is done to secure your data/photos in case someone finds your device.
When you open the camera app without unlocking your device by fingerprint (pin,...)
it does only show you the photos from the current session.
If you unlock your device and start the camera from the hoemscreen it will show you all your photos.
This has been this way on all my previous devices and also on iPhones for example.
What is weird is that it also shows no photo after unlocking when you open the camera app by long-pressing a navigation button
or double-pressing the power key.
edit: ok, after reading your post again I noticed that I basically repeated what you already wrote... I'm too tired :/

Same here. I was about to say this.

Front camera Not working!

I just received the phone, everything seems to work except for front camera. Back camera works fine but whenever I switch to front camera the app crashes and creates a log. I have tried changing setting for front camera, tried using open camera, checked permission. I don't know what to do. Any help will be appreciated!
Edit:- I have noted that camera setting can detect it as 8MP camera and I can change the setting for front camera, though it does not put any effect on front camera. The front did work for a second,
I managed to click a photo of it.

I just did that, returned it.

Magisk Assistant Lens Enabler

I made a module to enable lens from the assistant screen instead of having to take a picture and hit the button in photos. Seems to work fine and I still pass safetynet, it changes the fingerprint to that of a Pixel 2.
I modified it from the Pixel Experience Module, which I tried first, but unfortunately it caused instability and a lot of crashes. I decided to start by removing the overlay and that helped some but it seems that the stock ROM launcher interfered with the scripts even with no launcher selected.
I removed everything but stuff to enable lens, but it has one unfortunate side effect. I'm sure if you have tried any of the non-stock ROMs you seen the camera lose vibrancy with colors. It causes that but to a lesser extent than what I've seen in the past. It's perfectly usable to me, just wanted to let you know.
I haven't tried this on anything but the stock 8.0 ROM with magisk 16.4, but you're welcome to give it a shot.

... Please don't tell that lens needs Camera2 API to work. And I'm surprised why it just won't arrive for me in Assistant. Hopefully someone finds a way to make camera usable with Camera2 API. At least on Alberto's ROM it only looks good inside lens. In Moto camera is just jumping around between normal and pretty much b/w
PS: why are you including all those system sounds? They shouldn't be necessary at all and I actually made a module to rename the camera sounds to mute them, that could conflict with your module

No, it doesn't. On latest ROM by Alberto it finally popped up for me.

Working
Thanks, it's working on AospExtented for addison.

Question [SOLVED] Very strange ongoing camera issue

Hi, I have spent the last few weeks searching XDA, OnePlus and various other forums for an answer to this issue but have come up with no working fix.
The camera on my OP9P works absolutely fine sometimes, but other times it will show the feed for about 1 second and then freeze, completely unusable as the OP Cam app will also become unresponsive. Other times it will work, but the wide-angle 0.6x lens will not be accessible, the button for it will just not be there. Other times it will work 'fine' but the 1x lens will have a very strange overlay on it (photo attached).
I have tried every cam app on the first 10 pages of the Play store and even installed older versions of the OP Cam app and I eventually get the same issue. It happens in every app I use: WhatsApp, Instagram etc.
I have installed various ROMS also and still had the same issue.
Has anyone heard of this issue before, or know what it could be? My gut says it is hardware related but if I restart the phone, it usually works fine with no physical changes to the device.
Device was purchased around September 2022 and is in great physical condition, currently running OxygenOS 13.0 (LE2123_11_F.75).
Any help will be much appreciated.

Hardware issue

Is that 100% sure? I thought it could be hardware but a simple reboot usually fixes the issues for a little while.

I've reached out to the supplier who is going to repair it. Frustrating but quick response times so we'll see what happens.
