Nubia Z9 gives error on starting camera
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:


the ADB setup and command ready in PC
device connected to PC in debugging mode.
run adb logcat &gt; d:\dmp\device.log
run the camera app. Disappeared the error, the camera turns on
