Short version: Is there a way to prevent the phone from locking while on an active call? Former iPhone user here.... With the iphone, there was a sensor that detected when your face was near the phone, so the screen was blank and disabled but the phone was not locked. When you pull your face away, the screen is active again. On the Evo, it seems it has a similar sensor. However, after a minute it'll actually lock the phone for me while on an active call. So in order to hang up, I have to fumble with the phone to press the top button, then fumble some more to press end. Is there a way to prevent the phone from locking while on an active call, yet allow it to disable the screen when it detects it's being held up to the face?
