Re: why my phone kept sleeping during call

If you mean the screen going black, it's so you don't "cheek dial" during a call. As soon as you pull it away from your face it should come back.

If it happens even if it's not near your face, if you have any case on the phone, take the case off and try it. If that works, the case it being seen as "you" and the screen shuts off. (Some cases cause that.) If not, the proximity detector is bad and you'd have to bring the phone to a shop and have it replaced if it bothers you that much.
