Is there a setting that will keep the screen active (lit) during a phone call? It's fine for it to go dark on voice calls but it's a PITA when I'm in a phone tree and having to enter numerals constantly. I have to light up the screen (using the End key), enter numbers until it goes dark, and then go through the whole process all over again. I found a setting to keep the screen lit at all other times but I can't find anything to work during a call. I assume the going dark has something to do with the proximity sensor but I want to override that. Sprint Hero 2.1, rooted but with stock ROM, all updates Suggestions?
