changing camera - not recognized

DJac

@Keneda I already tried to back android 8... nothing more : the camera app crashed every time. (this is not the case in UT)
@gpatel-fr I will try the logs... I come back.

journalctl -F _SYSTEMD_UNIT give me :

is it this part ?

@DJac

this is an extract of dmesg yes ? not looking good at first sight.
However, should I understand from your previous post that you reinstalled Android (8) and that the camera app crashed ? If the cam don't work under Android, there is little hope that it will work under UT since UT use Android drivers.

DJac

@gpatel-fr yes, extract, from dmesg.
it indicate errors on 'CAM-SOC' but i can't understand what that mean... is it a physical probleme, or a software one ? I don't know...

It is the fist time that i change piece in a phone. Is there any special software thing to do, to validate the change ?

i tried to reinstall android 8. yes.
but it is worst (the camera app won't start). So i come back UT.
if it is not better i will try lineageOS (juste to compare... but without hope).

i will try lineageOS

If the problem is my point 2 (different hardware working but not 100% compatible) it could work since it may use a different driver version, since as far as I know this OS use native drivers (not Android) to access hardware. If it's another of the 4 possible problems I enumerated, nothing you can do at the software level will change anything.

DJac

it seems that the camera is detected as dummy video device 0x0000 (app 'camera test'). is that true ?

but i can't choose it...

it is extract from 'dmesg | less' commande.
what do you mean? I personnaly don't understand (except 'error' )

@DJac

Sorry but getting back to my 4 points, the only one were this is not working because of a hardware problem is 2): the new hardware is not compatible with the driver.

Android is (probably) not like Windows where when you pull a device from your computer and plug another in its place the system downloads another driver from the Internet: phones are not devices where you can plug and use new hardware.

So if the 2) point is correct, the driver installed with Android matches exactly the old camera, and not the new one. Since UT uses the Android drivers, I don't see a way forward with this camera.

DJac

okay... so the vendor give me wrong material ?

gpatel-fr

@DJac

I don't know what you ordered and what you received so I can't have any opinion on that.
Well, I'll post again the possibilities I see:

1) the hardware you got is defective
2) the hardware you got is functional, but there may be several submodels of the phone and the new camera is not 100% compatible with the previous one.
3) something else was damaged when the phone did fall.
4) there are problems with the repair.

Whatever the reason, if you asked for the exact same model that was included in your hardware and you got another variant, the vendor has made a mistake and you can ask for a return.
