Hi everyone.
I have huawei P9 plus VIE-L29 with microsd card attached, i was video recording a concert and trying camera features randomly when my storage became full and i changed the saving directory to the sd card and it was ok. After that i noticed sometimes when i switch between the front and rear camera the camera app freezes or crashes. And sometimes it works fine. The problem developed till the rear camera is not working at all but the front camera and flashlight are working fine. Then sometimes after restarting the phone the front camera and back flashlight started not to work. Randomly also sometimes they both work and sometimes they dont. Tried to put new software and permnantly unlocked my phone for this and it didnt work. Yesterday tried to change the camera piece front and rear and the same issue ! ... Its like not a software or a hardware problem ! What kind of problem is this please ? ... Sorry for being so talkative just tried to mention everything happened

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.
I have had no issues at all for almost an year with this phone. I was running oreo ever since I bought this phone. Suddenly, a day or two before upgrading it to pie 9.0, I found out in my Snapchat app that there was no back camera sign. First I thought, some weird snap update, but then I found out in system Camera app, it was even not showing the back camera. Whenever I would click on the rear camera sign from the top in Camera app, it would keep on swapping to the frontal secondary camera and then back to the primary frontal camera but no back camera was working. Also I found out that my Flashlight icon is hardened or greyed out, like it's been disabled forcefully. I can make it work using some other app, but it is frustrating why this is happening.
Now I am on android 9, rooted, and this problem keeps on coming and going. At times the back camera won't even work or open with the error "Camera not working" etc. Sometimes, the back camera would work but with only 3 weirded resolutions, like 12MP, 16MP, and some other. and the video mode will be extremely large or zoomed in at 16MP. Suddenly, the camera will start working normally again with all the perfect default resolutions. I tried everything from SAFE MODE to CLEARING THE CAM APP, RESETTING THE APP, but nothing works. All it seems like that camera has suddenly came to life and has a self-consciousness and a mood which it is controlling itself. Sometimes it wants to work and at times, it simply just gets disabled. Any idea what could be the problem? I am rooted using MAGISK.
Simular camera problems with Lenovo tab v7
I have a Lenovo tab v7 with almost the same problems, the rear camera wont work but occasionally the front camera works and the flash LED is dead.
Running Android 9 Pie as well, but not rooted yet.
Any ideas about what we can do about it, is the camera hardware due to be replaced?

It suddenly started happening almost a month ago, I was on oreo 8 and then upgraded to pie 9 but the problem persisted. It kept working for few days and then started to make problems again. I tried to read many forums for android users with the same problem but still haven't found a single complete fix for this problem other than that the rear camera needs to be refixed. But I am finding it hard to believe that even if camera was getting bad, there is no point of FlashLight getting greyed out/disable from the notification bar. It seems more like some kind of a process is not releasing the rear camera and flashlight module/process.
Hi everybody,i have search everywhere but did'nt seen similar case anywhere,my problem began after a litlle fall after this my camera started to behave strangely, like a reversal the motor brings out the front camera when I activate the rear camera and vice versa so the selfie camera works but only inside as you can see on the video, I already tried a factory reset.I also removed the back cover to check all the camera cables and nothing has changed except that when I disconnect the one from the front camera, the interface of the rear camera becomes "normal"
Thanks
summary of the situation the pop-up camera comes out when it should be in and stays in when it should be out

I don't know about the Poco F2 Pro but if it's something like the Huawei Y9 Prime with its pop-up camera it has a small magnet that "indicates" to the system when the front one is up or down and that makes the small motor that moves it activates the front camera, now the cell phone fell with the camera outside and the module was hit, it is possible that the state of the camera (down/up) has been "uncalibrated", in any case you would have to take it to a center specialized to be disassembled and checked because it seems to be a physical failure rather than a software one
thank you, indeed it is very interesting I had not thought of it did you see the video that I posted it is for this reason that I thought of a software defect but your proposal holds the road.
