i tried setting it to a minimum,
sleep mode, press volume up many times
check sound, still the same.
with the same setting tried to press
volume up on home, ringer bar goes up, checked
sounds, still at a minimum, but when press volume up on
sounds it automatically goes to maximum in one push of a button.
I am having the same problem as I can't hear it ring on top volume in my handbag so I have no chance when it turns the volume down by itself. Nice to know I'm not the only one with this problem but Apple fix this soon
well i know that when you plug in your headphones the volume automaticly changes to what you last had when your headphones were plugged in so make sure this is not the reason a lot of you guys are notices volume decreases. try it and see for yourself plug in headphones and put the volume somwere then unplug and watch the volume go back up
