Hi, "D/Camera ( 1033): app passed NULL surface" is the error log from the Camera client (frameworks/base/libs/camera/....)which will communicate with the Camera Service. This is message will ususally appear after some instance of time , the actual surface will be set if there is a call from Application to setPreviewDisplay with a proper surfaceholder.
Please read this : http://developer.android.com/reference/android/hardware/Camera.html Check in HAL, whether the proper Camera device is opened & you are able to query the capabilities of the Camera Hardware. If you doubt the functionality from kernel level (if you have time), Do one check, have a C application which will communicate with the kernel & dump the image frames onto framebuffer or to a file.
