I have a motorola MB860 phone and after a repair both frontal and back cameras don't work.
When I touch the camera button the camera app opens but the screen is black. If I touch the shutter button it looks like the picture is taken, but it doesn't save the picture. The flash doesn't work. And frontal camera is the same thing. Only a black screen. The camera app doesn't force close or anything. It opens normally, but cameras don't work.
I tried updating the software of the phone and still the same issue with both cameras.
Do you know if it is a hardware problem? Speakers, microphone, and volume keys work fine. I know they are connected to the flex cable of the front and back camera. So what does that mean?
I just need to know if I need to change the parts or maybe there is something else I can try to fix it. And what are the symptoms of a camera that doesn't work? Should the camera app force close or should it do what I mentioned before? Show a black screen?
Thank you

Are all cables properly seated in their connectors inside? And what kind of repair was done?

I would think that cables are well connected. The repair was change of touch screen and display. However, let me know if I am wrong, but I think rear camera and frontal camera are in different cables. So it's weird that both are not working. And I understand that one cable also has the speaker, mic and volume keys. Which they all work. So that is why I'm confused about this.

Rear camera has the vol up and down keys and headphones. Were both cameras working prior to repair?

Yes they worked before the repair.
What I would really like to know is if that behavior means that the cameras don't work and they need to be replaced. I'm guessing that if the volume keys and headphones are working then the camera must work too. So why does it show a black screen? The app opens, but shows a black screen.

Not necessarily. I had my vol keys not working and my camera and headphone jack still worked. It could be hardware related. But i seriously would double check the connections first. Are any on screen camera buttons showing up or is it just a blank screen?

Yes there are buttons showing up in the screen. I attached a picture of how the camera looks like.

The fact that the camera app does not force close leaves me feeling very curious. It might be helpful to know what ROM +kernel you are using, and posing the logs might give us a better chance at diagnosing the problem. It's possible that the cables were damaged during the repair, not at the connector end, but around the cameras.
Ok, here is the rom and all phone specs attached in a picture:

Now, I don't know where to get the logs you are telling me about.
Thank you.

Logcat and dmesg, as the kernel log may show device failure.
I Have the SAME Problem

I have THE same problem and both cameras stopped working as yours after the replacing the touch screen (digitizer)
---------- Post added at 08:21 PM ---------- Previous post was at 08:16 PM ----------
I used (flash) 3 or 4 different ROMS and it still not working, also i installed differen camera software thought normal apk and recovery too... this doesn't work
Nope, it is a hardware problem. IIRC, both cameras do not share the same flex, but I don't recall if one was connected to the other
Hit the damn thanks button instead!

Butas i saw inside the phone cameras do not connected to each other by the cable... they are connected just at the board/// Heating the digitizer cant be the cause of this effect//// or not

Some guys from motofan.ru said that this problem may be becuse of conflict with touchscreen controller on the main board of phone... that why I think that the replacement of touch may be the decision of this problem... But i'm not sure... And now i have no opportunity to find any touch for my atrix...
Also may you tell where did you buy your touch (digitizer) is it original or chinese version
P.S. in my case flash is working fine...
Have you tried reflashing SBF?
So my Prime's back 8mp camera is messed up. When I use my back camera, all I see is green lines running all across the screen. my front facing camera works fine. When I take a picture using back camera, green lines everywhere, can't see anything, the flash turns on, I can hear the auto focus working, but then it force closes. I believe that it is the cable connecting to the camera is out of place. I tried doing the pinching my tablet on the camera, and it worked, but when I let go, my camera glitches out. But now it doesn't work anymore when I try to pinch the camera.
I'm thinking about opening my tablet and try to reconnect the cable together. Has any1 ever fixed their camera problem? If so, how easy was it to do so.
Thanks!

Had the same problem a while back. Was still under warranty so I sent it in for repair. All I know is that it's a pretty common problem and that it definitely is a hardware issue.

Oh well my tablet I got a year ago on May 1st, so my warranty is expired. Also I unlocked the bootloader so i voided warranty anyways.
Happened to my back camera few days ago. Is there any known fix, outside warranty (bought my device two years ago, so it's not an option)?
I've never had this issue so I'm bot the best to advice. But It should be fixable, you just have to open your prime and do a little mod with the pogo pins, I'm pretty sure there was a thread with instructions for the fix.

I replaced my crashed lcd screen and digitizer with new ones from etradesupply.com. After I installed them serious problems started to appear. Firstly the mic went off. While the front camera was working, the rear started showing horrizontal green lines. Sometimes if I was pressing real hard at the centre of the screen the rear cameras were working fine. After a while the rear cameras went off. Initially when I was using the cams the cell was rebooting. I thought it was a rear cameras problem. So I ordered new ones. Meanwhile the rebooting situation stopped. Anytime I was try to use the cams, a black screen for a moment and the back to the previous screen. Additionally the front camera started doing the same thing. The new cams arrived, I changed them but same old situation. I 'm on stock RUU. Any help because I don't have a F$#%^& clue anymore...
i broke my nubia LCD and replace it sucessfully, but when i was moving the old modules for the new frame i broke my back camera... so i moved all the rest and my phone is alive again, but after testing all sensors i saw that the flashlight isnt working. check it circuit and its all responding but when i click to enable/turn it on, the icon goes brighter and get dark again.
i didnt move the old broked camera module so the phone have no back camera until i get the new one.
is it possible that my flash doesnt work cause the back camera is missing?
thanks in advice.
Hello
I had my phone in a drawer for over a year because the lcd shattered and a few months ago I ordered a 'new' screen and replaced it.
The first time I opened the phone I broke the front camera flex cable so I ordered a new one also.
The reason I'm giving a little context is to give you some insight to what could be the problem.
After replacing the front camera, it wont work. I tried installing the original stock rom, updating firmware via mmi codes and cleaning the connections.
What happens is, when I open the camera app (tried multiple ones of course), the back camera behaves very strangely and when I switch to the front camera, the phone either reboots or the app freezes.
This behaviour is green and purple lines through the image when opening, it kind of pulsates and if I get it closer to something bright it takes a few secons getting to a normal clear picture.
This is a recording I've made with the back camera: streamable.com/ilxln
Would apprecciate any info on this.
Thanks
