Hello people gust had the same thing phone hit the floor and both volume and silent button didn't work and I tried squeezing the phone together by the buttons but only volume button worked as long as I kept squeezing it then I worked out if I lay the phone I'n my hand flat and slap the back and front of the phone at the same time as if I was clapping my hands together fairly hard for a few seconds firmly both buttons now work and all seems good but squeezing it together or any other thing I tried wouldnt make the mute button work but slapping it together hard has sorted them both so hope this helps as I read all your coments and used them to work it out so thanks to u all
