I have tried to disable all possible sound on the phone before I use the camera function, but it still have the sound when I try to take pics.

this is not cool, sometimes I do not wish everyone around me to notice when I am taking a pic, it's call privacy! it's embarrasing sometimes when you want to take a selfie or something, and everyone turn around and look at you because they hear the camera sound!

is there any ways to stop this? thank you

1) On my testing device with this month firmware the camera-shutter sound is gone when you set the sound to silent
2) You can also use third party camera apps like open camera where you can set silent shutter in the settings

Have a look here: viewtopic.php?f=142&t=114125

But as mentioned, setting the sound to silent, or do not disturb, should help

Which firmware do you currently have installed?

sorry not a high tech person, don't know what is"firmware" or where to check that?
as I stated in my question, I turn off all possible sound on the phone which included the do not disturb too.same camera sound!

You can also use third party camera apps like "open camera" from playstore where you can set silent shutter in the settings

Firmware is the software (SW) your mobile phone is running on. Manufacturers provide regularly SW upgrades fixing bugs so it is good to check if your mobile phone has the latest SW available installed. If not, please try to upgrade.

Go to Parameters -> About Mobile Phone -> Updates it will check if your mobile has the latest SW installed

In any case, please copy here the SW version you have
