Android Fix - Camera

It stopped working a day later, I've just tried a fix that Google support suggested when I contacted them ....

"Go to Settings > Apps,Camera, and then touch Force stop.
Go to Settings > Apps, Camera, and then touch Clear cache.
Go to Settings > Apps, Camera, and then touch Clear data. Caution: Any data saved in this app will be erased.
--------
Then restart your device without opening the camera or any other applications that use the camera "
