[Q] Front and Back camera don't work in MB860 Atrix

[aerismel]

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.

by logs he mean getting a logcat output

Logcat and dmesg, as the kernel log may show device failure.

I Have the SAME Problem

I would think that cables are well connected. The repair was change of touch screen and display.

I have THE same problem and both cameras stopped working as yours after the replacing the touch screen (digitizer)

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

 

[andresrivas]

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

Touch Replacement

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.

Thank you

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?
