Wipe cache + dalvik cache. Reboot. Leave it 5 minutes. Clear camera data, hold your phone steady, open camera app. There should be notification Windows ask you, whether you want to use location tag or not. Don't tap anything! I repeat, don't tap anything. Leave it 10 - 15 seconds. You'll see the background actually is your camera on streaming. Try to move it slowly, and make sure if camera is calibrated.
