I have restored several times to install; Rub phone many times, both FW and eMMC flash several times, run: apt-get install - reinstall camera-ui-settings-camera-ui-y libqcamera1 005 libomap3camd
, Apt-get update, is not.

before normal camera.
* But there was one strange phenomenon:
When the camera is still normal after, one time I have to charge the battery, just moved Blutooth ... Meanwhile, my phone emits sound "z .. zzzz.zz" (like something was spinning and rubbing together)
* then I shall be drawing on camera
Is that the cause?
You do please let me know: camera before and after roughly 1 camera controller? If the previous camera after camera enforcement activity has not totally broken?
