Test this :

if(camera == null){

camera = Camera.open();
parameters = camera.getParameters();

List flashModes = parameters.getSupportedFlashModes();

    if(flashModes != null && flashModes.contains(Parameters.FLASH_MODE_TORCH)){

        //appareil supportant le mode torch
        parameters.setFlashMode(Parameters.FLASH_MODE_TORCH);
        camera.setParameters(parameters);
    } else if (flashModes != null && flashModes.contains(Parameters.FLASH_MODE_ON)){

        //spécial samsung
        parameters.setFlashMode(Parameters.FLASH_MODE_ON);
        camera.setParameters(parameters);
        camera.startPreview();
        camera.autoFocus(new AutoFocusCallback() {
            public void onAutoFocus(boolean success, Camera camera) { }
        });
    } else {
        parameters.setFlashMode(Parameters.FLASH_MODE_OFF);
        camera.setParameters(parameters);
    }  

        parameters.setFlashMode( Parameters.FLASH_MODE_OFF );
        camera.setParameters(parameters);
        camera.release();
        camera = null;

    } catch (RuntimeException e) {}
