hi guys this is David concise reviews and today I had a problem with my new Samsung s7 edge that's when you open up the camera it just stays black and then you get the error message that says warning camera failed that's not what you want to see I also had this problem with my s5 and I managed to fix it on that and the same thing fixed it on this so I'm going to take you through the steps that you should go through to get this problem fixed on your device because the good news is it's a software fault and not Hardware fault okay so the first thing you want to do is pull down the notification panel open up the settings go down to applications application manager and then you need to select camera once you've done that hit full stop and then full stop again then you want to hit storage and hit clear data and delete and then go back try your camera and hopefully that was fixed it for you a
