Simple, but not that easy, would have to go through the problem of unlocking the bootloader, rooting, then unroot then lock the bootloader again. Was hoping for a simpler way. I tried the silencer app, it worked in a way, but all it did was shut the volume off. I guess until then, I will just shut the volume off. But thanks for trying.

Wife says I am spending too much time on computer.
But I do stop when I go to bed, so it's not like I spend 24/7 on it!!!
