REAR camera can't start.

Hello.

Sorry for my English, my native language is Russian.

The rear camera in my G4 VS986 refuses to run; the front is running. Phone generally works fine, the only problem is with the rear camera.

Camera Module I rearranged the other phone, and there it works fine (camera module work fine).

I also updated the phone's firmware, but it did not change anything.

From this, I concluded that the problem may be in the power of the camera on the motherboard. Perhaps because of what that system left a capacitor or resistor.

Tell me I'm on the right track?

If this is true, tell me, how can I check?

Thank you!
