XA2 Ultra front cam startup error

Anytime that I attempt to open the standard [non-wide angle] front camera, I receive an unknown error warning (see screenshot). Have reset phone, etc.
Sony test utility shows error in standard front cam, however the wide-angle front cam functions normally. Rather than send the phone in for repair, I'm wondering if it's possible to have the front camera open on the wide-angle by default?
Unfortunately, once the camera app is open, the switch to wide angle is not functional, so there's no way that I can activate the wide-angle front camera. Any ideas? Thanks

Is a bug

It is not a bug. I do not have this problem at all. First.......
-Tell me what mods you have install
-tell me what you have for root and if magisk what modules
The camera error is being caused by something you have flashed or modded. Worst case scenario your camera is broken

I think the camera module is broken, as the phone is unrooted and unmodded, running the latest official stock for the region (Customized US). I might not bother to send it in for repair, as I don't use the front cameras much, anyway.
BUT- Is there any way to have the camera app open the wide-angle front camera by default? This would circumvent the problem. Thanks.

Probably not unless you know to edit an app and recompile the app. But good luck cause Sonys camera is tied into the framework so mess something and ur back to square one

How to flip (reverse) video image in AVin app?

I installed a front cam and connected it to aux video in cable so it shows picture in AVIN app. The problem is, the picture is mirrored like on a rear cam and the camera itself doesn't have an option to reverse image.
Is there any way to reverse image in the app itself or is there some other app that could use video input and has that option. Or is there a way to modify AVIN app so it shows normal image?
Please guys I need some help with this one.

I wonder if it is the camera itself that is reversed? Can you test it with another input?

Sorry, I didn't explain that clearly. The camera is meant to be in the back (hence the mirrored image), but unlike other cameras it doesn't have a loop wire to cut or any other way to change that built in mirrored mode. Fortunately I managed to locate front cam pin on my device so I connected it to that and the f-cam app has the ability to switch between the two modes. So I guess, problem solved

[OOS Camera] 7 Pro uses main camera even for zoom pictures?

I was messing around with the camera when I noticed something weird. When in the official camera app (tested in both implemented version and new 3.8.1), I can tap in the "three trees icon" (panoramic) and covering the top lense I see that's the one the phone is using. Now on to the 1x icon, the phone changes to the mid lense, but when tapping the big tree icon (telephoto), looks like my phone keeps using the same central lense, so the one in the bottom is never triggered.
Has anyone else ever experienced this?

Telephone is only used when there is a lot of light ( i personally tested it a lot). If you want to forcefully use the telephone camera use gcam mod with 'gcam for oos' module to enable auxiliary camera support.

in video mode telephoto is actually never used. that i did notice.

Indeed, I think they will allow for it in future updates.

Maybe that's the reason, after further fiddling I've found there's some kind of jumping between both lenses, it's not just that it doesn't toggle at all. So maybe the light is the reason for that. Thank you for your reply!

Front / Rear Camera

Hi. I have PX3 unit and want to connect rear and front camera ( Front only for parking), and i have problems....
So rear camera connected to : CCD AV in and to "back" and working fine when im switch to rear gear its opens automaticly in AVIN app.
But problem is front camera. I enable "front camera" in factory settings. Also enable DVR as CVBS., and switch to front camera after reverse.
And here problems starts.
I have 2 yellow RCA connectors in my unit: Video IN and DR-V
If i put it on Video IN i can open AVIN app and i can see front camera view , and black screen in DVR app
If i put it on DRV connector, i see front camera in DRV app and black screen in AVIN
But when i switch to reverse gear and then put front gear ( enabled switch to front camera after reverse) i see only yellow sign.
Its annoying to swich always to AVIN app cuz its mute radio and i neet to turn it on again after close AVIN
I have app "F-cam" but there is only black screen with yellow sign. Is there some option to usee only this app for rear and front camera? As there is button to switch cameras and it would be nice....
Pls help me guys to solve that problem... Many thx !
EDIT: hmmm i cant add images ;/ i've made album : https://ibb.co/album/fhm4wF

Hello just joined for tech support.
[Mod Moved to MTCD], your unit is probably an MTCD. Use CAM In on Connector K, and if that doesnt work, contact your reseller.

Only front camera or both? And for front camera use Video in or DR-v ?
EDIT: CAM in - is used by rear cam
Connector K - 3V output no matter what so i think its not correct cable to connect...
And i dont have free cables more... So F-cam app dont work at all... Rear cam induct AVIN screen, and nothing working for F-cam app i lost my hope...

I will ask my question, because eventually it may have a solution by changing the rom (as shown here).
So it's like this: I have an Isudar, in my car Mercedes w203 (2002), with android 7.1.2. It's working ... well.
Of course, I was left without the radio station ID, the dashboard instead shows a dash, and pressing the non-nude station switch button for the next preset station starts the search for another station. Apart from that it satisfies.
As I knew I could have other kind of elements added, I started installing a sim card to have Internet (although 3G), but it satisfies and I already put a reversing camera, no problem and it is working. But when trying to attach a front camera the question arose.
One of the cameras I bought, via USB, is not recognized by the system, but recognizes the application built into the camera which once installed continues to say that "there is a problem plugging in the USB plug" and / or the SD built into the camera. I searched the net and saw some that gave, but with radios of other brands, or with cameras of other brands, but more expensive, which I do not risk buying, because of the uncertainty of its operation.
If i connect the camera to my phone, no problem, install the app and show the image, record and that's fine. The difference is that on the mobile phone the connection is made by OTG (USB to micro USB) and the image is very good. In the car, with the connection made and the application open, the SD will record - with a non-current date (maybe the date of manufacture) - and show the movies with some quality.
With this camera was not for me I ordered another to connect in the rear of the radio via RCA plugs. And, only an application that comes on the radio (DVR) allows image if it is connected to RCA CVBS, but does not allow any recording. I will add photos to know if the reported problem can be solved without touching the software installed at the factory or if it will only be solved by installing a new ROM and, if so, if the radio has the proper specifications.
In advance, I am very grateful.

Rear Camera not working after installing MIUI 13.0.8.0

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.
