Nubia Z9 gives error on starting camera

Question

I bought the nubia z9 mini last year November.



About a week ago this message appears when using the camera:



"camera error"
"Please make sure no other applications occupy the camera, or try to restart the phone. "



I tried restarting but the same error. As requested, I've run adb dumpsys:





> adb shell dumpsys media.camera

Camera module HAL API version: 0x100

Camera module API version: 0x100

Camera module name: QCamera Module

Camera module author: Qualcomm Innovation Center Inc

Number of camera devices: 2 Vendor tags left unimplemented.

Camera 0 static information:


Facing: BACK Orientation: 90


Device version: 0x100


Device is closed, no client instance

Camera 1 static information:


Facing: FRONT


Device version: 0x100


I put the New version V3.67 Android Version 5.1.1 [ROM], the error is same.
Can you help me?

Answer

I was able to solve the problem (thanks to Firelord):



While "being debugged", the camera is turned on. For that, I've simply did the following:




  1. the ADB setup and command ready in PC

  2. device connected to PC in debugging mode.

  3. run adb logcat > d:\dmp\device.log

  4. run the camera app. Disappeared the error, the camera turns on
