Solution 1:

Did you see : Camera FLASH_MODE_ON not working on Moto X ?

What is

Parameters param = mCamera.getParameters();
Log.i("camera", param.flatten().toString());

logging ? =)

Solution 2:

Well, it seems as in moto x, flash operation works only with some combination of Camera preview size and Camera picture size. I used different combination and it worked.
