Okay, so there is no true "silence" mode if every time I accidentally hit the dictation button on the keyboard I get those annoying tones. Now, they wouldn't be so annoying if I wasn't at work. My manager doesn't really mind if I text between calls, as long as it isn't distracting, but it raises a lot of attention when I keep accidentally hitting it. Anyone know of a tweak to get rid of those tones? I've never heard of one and have tried searching a bit. Any help is much appreciated, thank you!
