On my LG-ally, I keep accidentally turning on silent mode. What exactly am I doing to cause this, and is there any way to disabled whatever the action is?
Are you perhaps using the volume control and going all the way to the "bottom"? That turns on silent mode in my Droid.
Are you hitting the wrong option on the menu when you hit the power button?
I'm not familiar with the LG Ally, so I don't know if they might have added an extra feature to make it easy to get into silent mode. Did you check the manual?
My apologies if this is too much of a me-too, but I'll second Al Everetts comments on the volume control.
I have this problem in 2 situations: 1. In the bracket I use in the car, one of the foam blocks rests a little on the down volume button. I've since cut the foam to reduce this issue. 2. When I'm holding it in landscape mode, I often bump the volume buttons.
There are on-screen indicators though, so I usually don't do it without noticing.
