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

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.

[Q] No Rear Camera

Hey All,
Replaced my cracked screen this weekend. Everything seems to be back to functional now, EXCEPT
- the ambient light sensor isn't working
- the rear camera isn't working
If I open the camera app (any camera app) it will show the front camera so I see my stupid face, but if I push the "use the other camera" button nothing happens.
Entirely possible I messed something up in the reassembly, BUT before I go and take the thing apart again I was wondering if there was anything I could try from a software / firmware perspective first.

Well, I am not the biggest hardware person, but I believe you can run the RUU and detect if it is a hardware issue. Again, I am not sure, you may want to double check.
Bump, anyone else have any suggestions for ways to "wake up" my camera?
FYI for anyone else who stumbled upon this thread - the problem was a disconnected ribbon cable that I missed. Between the motherboard and the plate that the camera sits on it a TINY ribbon cable (lengthwise) that has to plug into the back of the motherboard. It's nearly impossible to get even the tiniest tool in between the motherboard and the front assembly while this cable can reach its connector. So if you end up in this situation, have a lot of patience. I don't know if there's a way to get the screen off WITHOUT disconnecting this cable, but I certainly couldn't find one.

Camera Focus lock issue.

Hi everyone, i want suggestions guys, my opo's main camera focus is acting weird since last update, it was working great on 44s and then i updated it and the camera stopped working, cell phone showed theres no main camera attached to board, like camera app opened with front camera on by default, and there was no camera switching button. So i decided to deassemble the device thinking that it was some hardware issue, but everything looked fine in there, so i just disconnected and reconnected the camera sensor ribbon/connector to board just to make sure, and restarted device, canera came back somehow, but since then camera focus lock became horrible, anything out of 2feet range is blurred and out of focus, when cell auto focuses, theres a perfect focus point but camera locks its focus after that on blurred image, yesterday i flashed back to 44s and camera focus became a bit better, not perfect but way better than before, so now i think it is not entirely a hardware issue, something in camera firmware or drivers, can somebody help me on this issue please?
Same as mine after updating to lollipop.
guys please help saw something in the youtube about nexus 5 having the same issue fixed by tasker app running shell script. killall mm-daemon-camera tred but not working maybe some dev can help us use this method to fix the issue.

The camera does not focus after you change it

The camera on my phone started to show green screen and to show double image on the same screen, Then I bought 2 new cameras and they worked but neither one focuses.
If you bring closer a very strong magnet to the camera improves the focus but not 100%
-Already try with a clean system, new rom
-Try without the phone chassis
-Try in safe mode
-Try different camera apps, like opencamera camera L, among others
Help !
No body ?
Yeah they are fake thats why. You have to keep buying them and eventually you will get a working one. I myself bought about 4-5 of them (from ebay they were dirt cheap) and eventually one of them worked.
recently i bought a camera replacement part and replace it, yesterday i noticed it unable to focus, i search online for the solutions, and i tried restart, clear app data, flash the rom again, try many different camera app, try barcode scanner, none of it work, and i gave up and think it is hardware problem and i order the camera from other supplier...
but today, the camera can focus...the only thing i can think of what make this happen is i uninstall the google camera and install only footej camera. afternoon i try install google camera, initially it works well, but in the evening, it unable to focus again...
i try to uninstall google camera and left only footej camera, and try reconnect the camera cable, the camera is able to focus again...will try another few days and see how...

Rear Camera + Flashlight keeps getting disabled... Why ???

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.

Tof sensor dead?!

Hi everyone,
Has anyone experienced an issue with the camera?
Since my phone overheated, about 3 weeks ago, staying under the sun, I can't use the rear camera... I had the overheating warning pop up.
Basically if I launch the app, the app freezes, I can't switch to different rear cameras (wide, regular, telezoom) nor switch to front camera.
Sometimes I get a pop-up saying "can not connect to camera".
I can launch selfie mode directly from the app shortcut (by long pressing), other apps can't access the rear camera either and clearing cache of the camera app didn't change anything.
So, I had to change the back cover of the phone that had been previously cracked (nothing to do the camera not working), and I benefited the phone opened to try with disconnected cameras:
Telephoto works well, super wide as well.
Funny thing: the phone can use only the super wide camera to do both x0,6 and x1 (you don't notice that the main camera is not used).
Main camera worked.
2nd funny thing : portrait mode works perfectly without the Tof sensor being plugged in...
I plugged back the Tof sensor, it was still working, but stopped after restarting the phone. I removed it, cleared cache, it started to work again. I plugged the Tof sensor back in, it was working... I glued back the cover, and had the camera stop working within few minutes...
Long story short, has anyone experienced an issue with the Tof sensor? Which doesn't seem to be very useful...
I guess I'll try to remove it completely and check if the camera becomes stable.
I didn't find this part being sold :/
Regards, Charles
