Respuesta a "Why does my camera say, "Warning: Camera Failure""OK I have the perfect fix. I have battled with this common fault (come on Samsung get your act together). Factory reset, new cameras nothing worked. Was told it was a common fault by Samsung only fix replace the phone. Well by chance I made a call to my wife and pressed the "video call button". Camera worked instantly and so did the full camera function. It has failed again and I just repeat the video call fix. I believe the fault is software related and should fixed by Samsung who dont seem too interested. Hope this helps!
