Samsung Note 3 Phone - Clicking camera button fails to take picture
I knew why you have x1.0 appeared on the screen and can't take photo. I had the same problem and found out the answer. If two fingers touch the mon, it will appear x1.0 in order to zoom, and if there is still one finger on the mon and haven't move away, you can't press the camera button until all the fingers have moved away from the mon, the camera button will function again!
