How to make silent Fujitsu smartphone camera

If you have a Fujitsu Android smartphone that originates from Japan, I mean the production is intended for use in Japan,  you will not be able to use it's camera in silent mode.

Because in Japan it does not allow the camera shutter sound to be turned off by any legal means.

So how to make it silent? because you will use it and you are not in Japan. 

The solution : 
You can use the small application named: Mute Camera.
Go to Play Store, search the App using keyword: mute camera.
I recommend you to choose Mute Camere Free from HDM Dev Team.
Install it and then you are ready to use the camera with silent mode.
