Just throwing it out there: for those with InCall Power Manager issues-mine was really glitchy, either not turning the screen back on or waking to the home screen. Ever since making the #777 reg edit, InCall SEEMS to be working fine. The reg edit is for the Tachi dialer to work correctly but maybe this is an added bonus? Check your reg:
HKLM/Comm/Conn Mngr/Planner/Settings/SuspendResume should be set to #777
You need to do it with a reg editor other than Total Commander.
Hope you are as lucky as me
