Samsung A21s stop start up sound

[AK16]

Hi 

Does anyone know how to stop start up sound? I changed system UI >phone restarted > silent but I can't switch off start up sound. 

It is so annoying to hear start up sound every morning when I switch on my mobile phone. 

I hope anyone can help me out. 

Thanks

why would you turn the phone off at night? why don't you turn on the do not disturb settings overnight or put it on silence? I thought the whole point, or one of them of a mobile phone was the always on feature?

Try pressing the volume button, then the three dots, then the cog and finally turn the system volume to zero.

Thanks for your suggestion! 

I switch off sounds before I go to bed and switch on the sound when I wake up. It is the same thing I believe.

thanks N1vag, I checked my volume button.

System sound is nil but I still get this problem. I only get this notification sound every morning when I switch on. 

I spoke to the customer centre but no solution except for factory reset!

that's strange because I get no sound on boot up if my system sound setting is turned down.
