have the Bionic after two Blackberries and a Samsung smart phone before them. all had a button to mute the microphone while in a call. the Bionic has one but only on the dialer screen. so when the screen times out, you first have to wake it up, then swipe to turn on, then press the Mute button. Highly recommend that when in a call one of the permanent buttons be programmed to be a Mute Toggle.
When in a conference call and on Mute, when some one asks me a question it takes 3 -4 seconds [a very long time when people are waiting for answer on the phone] so my first statement after finally getting off mute, is sorry using a Verizon Motorola Droid phone that doesn't have a Mute Toggle. I am on conference calls for hours during the week. this feature is the most irritating for a business person.
Second most are the notification tones are all juvenile. A simple - single tasteful tone would be ok and not distracting.
i realize you want to sell tones for 3 dollars apiece, but Geeze already, 300 dollars for the phone and 200 dollars a month bill and i have to buy ring andnotification tones?
