I don't know how many others are having this problem, but I hit the mute and/or speaker button frequently while on a call. Is there any way to remove these buttons from the dial screen? The proximity sensor "works" but not in the sense that it works on the iphone. The screen takes several seconds to dim and then can pop on at any time during the call allowing these buttons to pressed with my cheek. Many many times, the speaker has been activated in an environment where it should not be. Are there any apps to prevent this, or do I have a bad proximity sensor? Does the fact that I hold the phone on the left side of my face effect this at all? (most people hold on the right) The last time I tried other advice of pressing home button, the phone has opened a self service apps and was about to start programming itself by the time I got off the phone. Anyone have any ideas?
