Hello,
I installed the developer preview as soon as it came out. Today I noticed my front facing camera is not working. It was working 3 days ago. In the stock camera app, the button to switch to front facing is not present. I installed a couple of other apps and there is no option for the front facing camera there too. So I tried to wipe the stock camera app's data. After that, the app does not start at all, it just crashes. 3rd party apps still work, but just for the rear camera.
I tried to reflash the system image for android m, but still, the problem persists. I happen to have a spare front facing camera from another broken nexus 5 (RIP old friend), and I still have this issue. Anyone got any ideas?
HI.
I have a problem with the rear camera.
The camera has stopped working focus.
My phone did not fall.
I tried to clear the cache camera and reebot the phone.
I tried to use different external applications to the camera.
Nothing helped.
My OnePlus' front popup camera had stopped working ( it would not Pop-up) and since the battery health was bad, I switched to a new phone.
So I tried flashing crDroid 9, the inbuilt camera app had 4 zoom option ".7x", "1x", "2.2x" and another "2.2x".
when I click on the third option the front camera popped up but the preview is still of back camera, and when I try to switch to front cam it simply goes blank for a second and shows the back cam preview.
So my question is,
is it a problem with persist.img? if not are there any fixes?

Huawei P40 pro front /selfie camera issue – continuous restarting camera app
Hi guys,
I bought a second hand Huawei P40 Pro ELS-NX9 last year in November. The seller told me selfie camera is not working due to an update of the EMUI.
Issue: camera app works fine, I can open it and it will go straight in the main camera mode photo/portrait, I can than navigate all the options and everything works fine. If I go to push the selfie button than app will try switch to that but I ll have only a very blurry image of the last thing showed on the rear camera for 5ish seconds and then go back to the rear camera, (will freeze on the last image showed before pushing selfie button) and close the app. It will open it again show a black image and then close the app again…this loop will continue until manually closing the app.
Fun fact: if I i put a finger over the front camera ( without touching it ) and try to unlock the phone it will show : DO NOT COVER TOP OF THE SCREEN – mistouch prevention enabled …that should be the other part of the camera I replaced
Me trying to fix it: I did the downgrade to EMUI 10 but the camera did not work
Factory restore – clear cache
Replaced selfie camera with new one
Replaced camera with working camera from another phone (bought from a store)
Any idea what the issue could be?
Thank you for your help
Hello everyone, after years of resolving my issues just by looking here on XDA, it's time that I post an issue with my Poco F2 Pro. Sorry if my english is not correct (i'm from Italy btw).
So, yesterday i got a notification that told me that i could download and install the MIUI latest version (13.0.8.0), and i did it. Later, when I wanted to send a photo i opened the rear camera and "surprise" it wasn't working. Here's what I found out trying some apps:
GCam >> when I open the app, the rear camera comes out but on the screen i see the frontal camera. If I swipe to the rear camera, the app freezes for a bit and then it cloes itself.
Camera's Stock App >> when I open the app, the rear camera comes out but on the screen i see the frontal camera. If I swipe to the rear camera, i visualize the Macro Camera.
Whatsapp >> the app doesn't even give the option to switch to the rear camera (in fact, i think that the app does not detect the rear camera) but i can easily take photos with the frontal camera.
Instagram >> here i have the option to swap to the rear camera but if I do so, the app freezes and it closes itself.
CIT Mode >> when I check for the Rear Camera, i get the error "get the empty or null camera id".
I brought these examples hoping to show that it's not an hardware problem, since before the update I used the phone and the rear camera easy as always, and i think that the update could have compromised or smth the way the phone detects the rear camera. Anybody has the same problem? Or at least anybody knows how to fix that?

Delete all other camera apps, erase all Miui camera data, reboot.
Same, factory reset.

Thx i'll try asap, meanwhile i have a question: erasing all Miui camera data means that I lose the photos that I took with the miui camera?

Nope, it's cache and settings.
Also, check permissions, long press camera icon, info/permissions.

This is indeed the solution if the factory reset does not change anything and before to concluded that there is a hardware problem.
