When receiving a call, how do you mute the phone? This might seem like a stupid question, but I couldn't find the answer on this SE so here goes. When I receive a call and my phone starts to ring, how do I mute the phone without answering or dismissing the call? Is this done differently depending on the Android OS version?
Just press any volume button while its ringing.
On side note, make sure there isnt an option like answer by volume buttons in settings-&gt;accessibility. If there is, make sure its disabled. If its not there, then you are fine ;)
Hope this helps.
