Flashing custom rom sounds a bit OTT isnt it
is it a Samsung's official recommendation is it?
As I said I found a solution in the link i pasted above so i do not need further assistance (and I was not expecting further replies but thanks anyway).
My point here is that if "mute ALL sounds" option does not mute "all" the sound for whatever the reason is, then either it should be fixed or if this can not be done, then the description should be changed so that the option does what it says.
also in my opinion, making the camera sound dependent on the carrier, that is a design issue. If Nokia can do it, apple can do it and HTC can do it on the same carrier, then there should be no reason why Samsung can not do it.
Anyway, you can close this issue. Thanks for your support.
